Prepare your pool system for winter with this drain valve set for 50 mm PVC pipes. The drain valve allows you to drain any water remaining in the connected pipe section. This helps reduce the risk of frost damage when the system is out of use.
The set is intended, among other uses, for draining pipes in your pool's solar heating system. The lever makes it easy to open and close the valve.
Helps prevent frost damage
Water remaining in a pipe can expand when it freezes, causing damage to pipes or fittings. Draining the system before a frost period reduces this risk.
The drain valve makes it easier to drain the system, but does not automatically ensure that the entire system is free of water. Water may remain in bends, low pipe sections, or connected equipment. Therefore, also follow the winterization instructions for the other components.
Easy lever operation
Use the lever to operate the valve when draining and restarting the system. Install the drain valve in an easily accessible location where the water can drain away in a controlled manner.
For proper operation, the pipe section to be drained must be able to drain towards the drain point. The placement of the valve is therefore important for the result.
For 50 mm PVC pipes
This set is intended for use with 50 mm PVC pool pipes. It allows you to incorporate a drain point into the piping, for example in a solar heating system.
Before installation, check which fittings are required. The exact contents of the set and the type of connection fitting are not specified in the provided information.

With the PS40 polystyrene end cap, you seal the open ends of suitable polystyrene pool blocks before filling the walls with concrete. The end cap seals the formwork and helps prevent concrete from leaking out through the ends during filling.
The end caps are made of polystyrene, also known as Tempex. This lightweight material is easy to handle and is compatible with the polystyrene pool block construction system. A practical component for preparing the pool walls for concrete pouring.
Sealing the open block ends
When building the pool walls, open ends may be created that must be sealed before filling with concrete. Place the end caps at the bottom and top of these open ends, as specified for the construction system.
The caps seal the ends of the blocks and remain part of the formwork after filling. Check beforehand whether the end cap is suitable for the block type being used to ensure a proper fit.
Install before filling with concrete
Install the end caps while building the pool walls, before filling the blocks with concrete. Then check that all open ends are sealed and the caps are securely in place. The walls can then be filled according to the construction system's processing instructions.
The number of end caps required depends on the pool layout and the number of open block ends. Therefore, include them in your material calculation so that the formwork can be fully prepared for concrete pouring.
With the Small High-density Polystyrene pool block, you build the foundation for your own swimming pool step by step. The compact size of 100 x 25 x 25 cm and the low weight make the blocks easy to handle and place. At the same time, the insulating polystyrene helps to limit heat loss through the pool walls.
The blocks form a permanent formwork for a reinforced concrete pool wall. During construction, you install steel reinforcement and fill the blocks with concrete. This combines the ease of working with polystyrene with the strength of a concrete structure. A practical solution for DIY builders and pool builders who want to create a custom-made insulated pool.
Compact size and easy to work with
The Small version has a length of 100 cm, a width of 25 cm and a height of 25 cm. This handy size makes it easy to move the blocks, align them and build them up layer by layer.
With each layer, you increase the wall by 25 cm. Six layers are required for a wall height of 1.50 meters. Each block represents a wall surface of 0.25 m², so you need four blocks for one square meter of straight wall. Corner joints, recesses and cutting waste must be calculated separately.
Stackable building system with permanent formwork
The polystyrene blocks are placed on a prepared foundation and together form the formwork of the pool wall. During construction, the required reinforcement is installed. Once the structure is ready and checked for dimensions and stability, the blocks are filled with concrete according to the system instructions.
After filling, the blocks remain in place. Therefore, no temporary formwork of the walls needs to be removed. The polystyrene remains part of the wall construction and provides an insulating layer around the concrete core.
A solid foundation with concrete and steel reinforcement
The structural strength of the pool wall is created by the combination of concrete, steel reinforcement and a correctly executed foundation. The blocks make it possible to build this concrete wall in an organized manner.
The required reinforcement and the execution of the floor slab must match the pool design and the conditions on the construction site. The position of any stairs, tanning ledges and other structural components must also be determined in advance. In this way, the entire pool construction forms a cohesive whole.
Insulating walls for less heat loss
Expanded polystyrene, also known as EPS or Styrofoam, naturally has insulating properties. The blocks therefore help to limit the heat transfer between the pool water and the surrounding soil. In a heated pool, this can contribute to a lower energy requirement to keep the water at temperature.
How much heat the pool retains depends on the complete execution. In addition to wall insulation, factors such as floor insulation, a pool cover, weather conditions and the desired water temperature play a role. The polystyrene pool blocks therefore form part of a well-insulated pool.
Room for your pool design
The building system is suitable for constructing structural pool walls. With suitable components and a good structural design, elements such as entry stairs and tanning ledges can also be included in the design.
During preparation, determine where the lighting, return fittings and other wall penetrations should be placed. These components are incorporated into the walls during the construction phase. By fixing their position in advance, you prevent major adjustments after the concrete has been applied.
From foundation to watertight finish
The construction begins with excavating and preparing the construction pit. Next, the floor reinforcement and the concrete floor slab are installed according to the construction plan. A flat, correctly executed floor slab forms the basis for accurately placing the first row of blocks.
Then the walls are built up layer by layer, including reinforcement and built-in components. The connecting of the blocks and filling them with concrete are done according to the processing instructions of this version.
After filling, the walls are prepared for a suitable watertight pool lining. The blocks and the reinforced concrete core form the wall construction; the lining provides the watertight finish and the final appearance of the pool.
Calculate the required materials in advance
For an initial material estimate, you can assume four blocks per square meter of straight wall. The final quantity depends on the dimensions, corner details, recesses and any additional elements. Therefore, allow for a reserve for cutting waste and damage.
The required concrete volume depends on the internal construction of the Small block. Use the product specifications of this version for this purpose. Calculate the concrete for the floor slab, stairs and other components separately, so that you have a complete overview of the required materials.
With the High Density XXL polystyrene pool block, you can quickly and clearly build the walls of your pool. Thanks to the generous size of 125 x 25 x 50 cm, each block covers a large wall area. The height of 50 cm means that you can achieve a wall height of 1.50 meters with just three layers.
The blocks combine the low weight and insulating properties of polystyrene with a construction system that is filled with reinforced concrete. This creates a sturdy pool wall with a permanent, insulating formwork. A practical choice for DIY builders and pool builders who want to efficiently build larger wall areas.
Large size for quick wall construction
The XXL version has a length of 125 cm, a width of 25 cm, and a height of 50 cm. Each block therefore represents a wall area of 0.625 m². Due to these large dimensions, fewer blocks and layers are needed than with smaller versions.
For a wall height of 1.50 meters, you place three layers. This limits the number of individual placement steps. The larger size does require sufficient working space and careful alignment, so that the walls are built straight and to the correct dimensions.
Lightweight and insulating polystyrene
The blocks are made of expanded polystyrene, also known as EPS or Styrofoam. This material is light and therefore easy to move during construction. Despite the large size, the blocks remain easy to handle before they are filled with concrete.
Polystyrene naturally has insulating properties. The blocks help to limit heat transfer between the pool water and the surrounding soil. In a heated pool, this can help reduce the energy required to keep the water at temperature.
The final heat savings depend on the complete pool. Soil insulation, a good cover, the desired water temperature, and the weather conditions also affect heat loss.
Permanent formwork for a concrete pool wall
The construction system works with blocks that are built up layer by layer. During construction, the required steel reinforcement is installed. Then, according to the processing instructions, the blocks are filled with concrete.
The concrete core forms the load-bearing pool wall together with the reinforcement. The polystyrene blocks remain in place as insulating formwork. Therefore, no temporary wall formwork needs to be removed after filling.
A good foundation, suitable reinforcement, and correct concrete processing are essential for the final construction. Coordinate these components with the pool size, design, and conditions on the construction site.
Options for a custom-made pool
With the XXL blocks, you build the walls of a structural pool. With suitable components and a good structural design, entry stairs and shallow areas can also become part of the design.
Due to the block height of 50 cm, this version is particularly practical for wall heights that are multiples of this. For non-standard heights or smaller details, additional custom work may be required. Check in advance which accessories or additional block sizes fit this system.
When designing, also take into account pool lighting, sprayers, and wall penetrations. These components are installed during the construction phase, before the walls are filled with concrete.
From a prepared construction pit to a finished wall
Construction begins with excavating and preparing the construction pit. Then, the floor reinforcement and the concrete floor slab are installed according to the construction plan. A flat, correctly executed floor slab forms the basis for placing the first row of blocks.
Then, the walls are built up and provided with reinforcement and built-in components. During these works, the dimensions, alignment, and stability are checked. The connecting, supporting, and filling of the blocks are done according to the instructions for the XXL version. The block height of 50 cm does not automatically determine how much concrete can be poured at once.
After filling, the walls are prepared for a suitable waterproof pool liner. The blocks and the reinforced concrete form the structure; the liner provides the waterproof finish and the final appearance.
Calculate the required quantity in advance
Each XXL block has a wall area of 0.625 m². For an initial estimate, divide the calculated wall area by 0.625. This amounts to an average of 1.6 blocks per square meter of straight wall.
The final order depends on the dimensions, corner connections, recesses, and any stairs or shallow areas. Round up to whole blocks and allow for extra material for cutting waste and damage.
The required concrete volume depends on the internal block construction. Therefore, use the specified concrete consumption for this specific XXL version. Concrete for the floor slab and additional structures should be calculated separately.
Build a sturdy and well-insulated foundation for your swimming pool with these high-density polystyrene pool blocks. The 100 x 25 x 30 cm blocks combine a low weight with a hard outer layer and a practical stacking system.

The principle is similar to building blocks: you place the blocks layer by layer to build the desired pool wall. Thanks to the 100 cm length, you can make quick progress. For a wall height of 1.50 meters, five layers of 30 cm are required.
The low weight makes the blocks easy to move and handle. This is convenient when setting out and building the walls and makes the system attractive to DIY builders. A level foundation, accurate measurements, and correct placement form the basis for a good result.
High density for a sturdy wall surface
These high-density pool blocks have a PS60/30 construction. The core consists of polystyrene with a density of 30 kg/m³ and is fitted with a hard outer layer with a density of 60 kg/m³. This outer layer makes the surface more resistant to dents, scratches, and deformation during processing.
Thus, the block combines the ease of use of lightweight polystyrene with a sturdy surface. The hard outer layer helps keep the wall neat during construction and in preparation for the final pool lining.
Concrete and reinforcement provide structural strength
The polystyrene blocks form the formwork for the pool wall. During construction, the required steel reinforcement is installed, after which the hollow spaces are filled with concrete. The blocks remain in place after filling and form an insulating layer around the concrete core.
The final strength is determined by the entire structure: the subsoil, floor slab, reinforcement, and concrete fill must be coordinated. The dimensions of the pool and any steps or tanning ledges also play a role. The walls are filled according to the system's processing instructions.
Insulating properties for heat retention
Polystyrene helps limit heat transfer between the pool water and the surrounding soil. As a result, the blocks help retain heat. In a heated pool, this can reduce the energy required to keep the water at the desired temperature.
The total energy savings depend on the entire pool construction and its use. In addition to wall insulation, floor insulation, a good pool cover, the outside temperature, and the desired water temperature also have an impact. These pool blocks thus provide a practical foundation for a well-insulated pool.
Flexible in shape and layout
With the blocks and suitable accessories, you can realize various pool designs. In addition to straight walls, entry steps and tanning ledges are also possible, provided they are properly designed structurally. This allows you to tailor the pool to the available space and your preferences for comfort and use.
When designing, also take into account the placement of lighting, return jets, and other wall penetrations. These built-in components are installed during the construction phase so that they are incorporated into the pool wall in the correct position.
Step-by-step installation
Construction begins with excavating and preparing the construction pit. The floor reinforcement is then installed, and the concrete floor slab is poured and finished to the desired height. This floor slab forms the foundation for the pool walls.
The first row of blocks is accurately placed on the prepared floor slab, as prescribed, in a mortar bed. The remaining layers, steel reinforcement, and built-in components follow. The blocks are connected or bonded according to the system's instructions.
Once the walls are fully built and inspected, they are filled with concrete. This is followed by preparation for a suitable waterproof pool lining. The blocks and the concrete core form the wall structure; the pool lining provides the waterproof finish.
How many blocks and how much concrete do you need?
The required quantity depends on the pool size, wall height, corner connections, and any additional elements. For an 8 x 4 x 1.50-meter pool, according to the specified calculation method, you will need approximately 100 blocks and about 4.3 m³ of concrete for the walls.
This calculation assumes five layers and a calculated perimeter of 25 meters, including a 1-meter allowance. The indicative concrete consumption is 115 liters per square meter of pool wall. Concrete for the floor slab and additional material for steps or tanning ledges are not included.
Order at least 1 to 2 extra blocks for limited cutting waste or potential damage. For a design with many corners or custom dimensions, a larger reserve may be required.

Struggling with foam in your swimming pool, spa, hot tub, or other water circuit? Rijo Foam Down is a liquid defoamer that helps to quickly reduce unwanted foam. The product is suitable for situations where foam is caused by, for example, soap residues, cosmetics, body oils, contamination, or residues of other water treatment products.
The generous 5-liter packaging is particularly suitable for regular use, larger water installations, and professional applications.
Reduces unwanted foam formation
Foam on the water surface usually occurs when organic contamination and surfactants are whipped up by air and water movement. This is especially common in spas and hot tubs, as massage jets and air blowers are constantly adding air to the water.
Foam can also occur in swimming pools, fountains, and other circulating water systems. Rijo Foam Down helps to quickly break down existing foam, making the water surface look calmer and better maintained again.
Quick and easy application
Rijo Foam Down is liquid and therefore easy to add. Distribute a small amount evenly over the foaming part of the water surface while the circulation is switched on. The product then disperses through the water and reduces the foam layer present.
Always start with a small amount. Only add more if the foam has not disappeared after sufficient circulation time. Overdosing is not necessary and can put unnecessary stress on water quality.
For the exact dosage, always follow the instructions on the label or the provided product sheet.
Suitable for various applications
Rijo Foam Down can be used, depending on the instructions on the product label, for:
Swimming pools
Spas and jacuzzis
Hot tubs
Whirlpools
Fountains
Ponds and decorative water features
Industrial and technical water circuits
Other water installations where unwanted foam occurs
Before use, always check whether the product is suitable for the specific installation, materials used, and water treatment products present.
Foam is often a sign of contamination
A defoamer removes the visible foam but does not always eliminate the underlying cause. When foam regularly returns, it is important to also check the water quality and the installation.
Common causes of foam formation include:
Soap and detergent residues in swimwear
Shampoo, shower gel, and hair care products
Sunscreen and cosmetics
Skin fats and body oils
A dirty or saturated filter
A high concentration of dissolved substances
Old water
An incorrect pH level
Too low calcium hardness
Residues of cleaning or water treatment agents
An incorrect combination or overdose of chemicals
In case of recurring foam, it is advisable to clean the filter, measure the water values, and, if necessary, replace part of the water.
Instructions for use
First, check the pH level and general water quality.
Clean or check the filter if it may be contaminated.
Shake or mix the packaging according to the instructions on the label.
Let the circulation pump run.
Add a small amount of Foam Down directly to the foaming water.
Distribute the product as evenly as possible over the surface.
Let the water circulate sufficiently.
Check the result and only add a small additional amount if necessary.
Do not add the product simultaneously and undiluted with other chemicals. Always allow sufficient time between different treatments and follow the instructions for use of the respective products.
Regular maintenance remains important
Rijo Foam Down is intended as a practical solution for existing foam. For long-term clear and comfortable water, proper maintenance remains necessary.
Pay attention to:
A correct pH levelSufficient disinfectionRegular cleaning of the filterTimely replacement or replenishment of filter materialRemoving organic contaminationRegular water changes for spas and hot tubsShowering before useSwimwear without detergent residuesCorrect dosage of all water treatment agents
Safe use and storage
Before use, always read the entire label and the safety data sheet. Wear suitable protective gloves and eye protection if specified on the label.
Store the packaging:
Upright and tightly closed
In the original packaging
Cool, dry, and frost-free
Away from direct sunlight
In a well-ventilated area
Out of reach of children and pets
Separated from food and other chemicals
Never mix Rijo Foam Down directly with chlorine, acid, lye, or other concentrated pool chemicals. Use separate measuring cups and dosing tools for different products.
Important
Rijo Foam Down is a tool against visible foam. If the foam returns quickly, check the filter, pH, disinfection value, alkalinity, calcium hardness, and general water quality. In spas, a partial or complete water change may ultimately be more effective than repeated use of a defoamer.
Save energy and keep your pool warm for longer
With the Rijo Heat Shield Liquid Pool Cover – 1 Liter, you create an invisible, heat-insulating layer on the water surface of your swimming pool. This innovative liquid cover helps reduce heat loss, limits water evaporation, and ensures that the pool stays at temperature for longer. As a result, you use less energy to heat the water and save on water and maintenance costs.
Unlike a traditional summer cover, you do not need to place or store a heavy tarp. The liquid cover works completely automatically and is invisible while swimming.
Invisible protective layer
Rijo Heat Shield forms an ultra-thin, biodegradable layer on the water surface. This layer reduces water evaporation, which directly results in less heat loss. Because the majority of heat loss occurs through evaporation, using a liquid pool cover can contribute significantly to lower energy consumption.
The protective layer restores itself automatically when the water moves or when people are swimming.
Less evaporation, less energy consumption
By limiting water evaporation, not only is heat better retained, but you also need to refill the water less frequently. Additionally, pool chemicals such as chlorine remain effective for longer because less water is lost.
This makes Rijo Heat Shield an excellent choice for both pools with a heat pump and pools heated with solar collectors, electric heaters, or heat exchangers.
Suitable for almost any pool
Rijo Heat Shield is suitable for:
Above-ground pools
In-ground pools
Indoor pools
Outdoor pools
Chlorine pools
Saltwater pools
Pools with automatic disinfection systems
The liquid cover does not affect the operation of filters, skimmers, or pool pumps and can be used safely in combination with most pool installations.
Easy to use
Add the recommended amount of Heat Shield directly to the pool water. The liquid spreads across the entire water surface by itself and immediately forms an insulating layer.
For optimal results, it is recommended to replenish the dosage regularly, depending on the size of the pool, the outside temperature, and the intensity of use.
Environmentally friendly and safe
Rijo Heat Shield is biodegradable and safe for swimmers when applied according to the instructions. Because less water evaporates and less energy is required to heat the pool, you also contribute to more sustainable pool maintenance.
