Non-return valves, also known as check valves, prevent water from flowing backwards in a system. This could occur due to a sudden drop in pressure in the supply lines, meaning water carrying contaminants could flow back from the shower and into the mains. They also help maintain pressure in mixer showers by ensuring hot and cold water do not flow back into the wrong pipes.

There can be several non-return valves installed in the system and they're usually located where the risk of backflow is highest.

If you’re unsure about the process of choosing or installing non-return check valves, visit our trade experts at your local branch. They'll point you in the right direction.
