Faema Non-Return Valve One-way check valve used in the water supply line to prevent backflow into the pump or boiler feed. COMPATIBILITY Fits: Faema-platform water supply lines Replaces: F_322 INSTALLATION Technician-level, requires accessing the water supply plumbing; mind flow direction when installing. PRO TIPS Non-return valves are directional, there's usually a flow-direction arrow stamped on the body. Installing it backward blocks water flow entirely rather than just failing to prevent backflow, so check orientation before sealing everything back up.
The catalog often lists the same model at several merchants — worth a price check before you buy.
