Restore factory performance and protect your water system with this Genuine OEM Metabo 316060340 Replacement Valve Assembly. This component serves a dual purpose: the built-in mesh screen filters out harmful sediment, sand, and debris, while the integrated check valve prevents water from draining backward out of your lines when the pump cycles off.If your pump is losing its prime, struggling to build consistent water pressure, or has a cracked/clogged integrated filter module due to winter frost damage, this direct drop-in replacement is the exact fix required.
