Check valves for swimming pools

Check valves for swimming pools

Check valves play a crucial role in a properly functioning pool system. They ensure that water can only flow in one direction and prevent water from flowing back to your pump, filter, dosing system or other vulnerable components. Check valves are therefore often used in pipes that are below the water level or in installations with automatic dosing and heat pumps.

What is a check valve and how does it work?

A check valve - also called a check valve - is a valve that closes automatically when water tries to flow back. This happens, for example, when the pump is turned off or water pressure drops. The valve opens automatically as soon as the water flows in the right direction. This keeps your system protected and prevents unwanted pressure on pumps or contamination of other pipes.

What do you use a check valve for?

• To prevent backflow in automatic dosing systems (such as pH or chlorine pumps)
• As protection of heat pumps or UV lamps from water damage
• In pipes below the water level, for example, to prevent draining of pipes
• To ensure filters or sand barrels remain filled at pump stop

Types of check valves for swimming pools.

You can choose from different types of check valves, depending on your installation:

• Transparent models: useful for visually checking that the valve is working properly
• Valves with spring mechanism: close faster and more securely at low pressure
• Valves without spring: offer less resistance and are suitable for circulating water
• With adhesive or threaded connections: suitable for your pipe type (PVC adhesive or threaded)

Our range of check valves

In our offer you will find check valves in different diameters, such as 50 mm and 63 mm, suitable for use in pool pipes. Many models are easy to disassemble for cleaning and maintenance. Transparent versions offer additional convenience and are ideal for dosing systems or installations that are checked regularly.

Benefits of check valves

• Protect your system from damage caused by backflowing water
• Extend the life of pumps and accessories
• Preventing leaks and air ingress into pipes
• Easy to install and easy to maintain

Tip: Always place the check valve in the correct direction of flow (indicated by an arrow on the valve) and check regularly for fouling or scale formation.
