Check valves and non-return valves
Find check valves for plumbing systems, including non-return valves and one-way valves designed to help prevent reverse flow in suitable pipework.
Check valves are used where water needs to flow in one direction only. They can help protect pipework, appliances or plumbing systems from unwanted backflow when installed correctly.
Before ordering, check the pipe size, flow direction, connection type and whether the valve is suitable for your application. Always fit the valve in the correct direction as marked on the product.
