22mm Compression Single Check Valve – WRAS Approved Brass Non-Return Valve
The H-10103 is a 22mm compression single check valve (non-return valve) in WRAS-approved brass. It allows water to flow in one direction only, preventing backflow and the risk of contamination from reverse flow in potable and heating pipework. Both ends are 22mm compression — no soldering or specialist tools required, just tighten the nuts onto the pipe.

Key Features
Prevents backflow contamination
The spring-loaded disc opens under forward flow pressure and closes immediately when flow stops or reverses — blocking any risk of contaminated water being drawn back into the supply. Required by the Water Supply (Water Fittings) Regulations in any installation where backflow risk exists.
WRAS approved — potable water safe
WRAS approval number 1304908 confirms compliance with the Water Supply (Water Fittings) Regulations 1999 for use with potable (drinking) water. Suitable for cold mains, domestic hot water, and expansion vessel connections.
Tool-free compression fitting
22mm compression connections on both ends — no soldering, no heat, no flux. Hand-tighten the nuts onto the pipe and finish with a spanner. Can be installed on copper or plastic pipe using the appropriate olive type.
