Jabsco 44412 Chrome 45-PSI Flush Mount Regulator

The Jabsco 44412 is a chrome flush-mount water pressure regulator holding 45 psi, with a removable strainer.

Unregulated shore water is the risk this addresses, and it is a bigger one than most owners realize. Dock and campground supply pressure can run far above what marine plumbing is built for. A fitting or hose that lets go while nobody is aboard floods the boat from an unlimited source.

The regulator holds output steady at 45 psi across low and high flow rates, so pressure does not spike overnight when nothing else on the dock is drawing. That overnight period is when the pressure is highest and when nobody is there to notice a failure.

A removable strainer protects valves and seal seats from pipe scale and debris carried in from the dock main. Being removable it can be cleaned rather than replaced, which matters because dock water quality varies and a clogged strainer otherwise means a new part.
