Jabsco Flush Mount Water Pressure Regulator 45psi - Chrome

The Jabsco Flush Mount Water Pressure Regulator 45psi in Chrome (Model 44411-2045) is engineered to protect your vessel's fresh water system from the damaging effects of unregulated dock-side and campground water pressures. Whether you're docked at a marina with variable city water supply or connected to a campground faucet, this regulator maintains consistent output across both low and high flow rates, preventing seal degradation and component failure caused by pressure spikes.

The 45psi outlet pressure setting is the standard for marine plumbing systems, balancing water delivery performance with seal integrity. The removable strainer cartridge is a practical feature that intercepts pipe scale, sediment, and debris before they reach sensitive valves and faucet seats—a common cause of leaks and reduced water flow after connecting to unfamiliar water sources. The flush-mount chrome body integrates cleanly into galley and head installations, resisting corrosion in salt-air and humid marine environments. Its compact design (7 x 4 x 8 inches) fits standard cabinetry cutouts without modification.

This regulator is essential for cruising sailboats, power vessels, and RVs that rely on external water hook-ups. Serious boaters running extended offshore passages or seasonal cruises will recognize that pressure regulation is non-negotiable preventive maintenance—it costs far less than replacing a burst water line, leaking through-hull fitting, or compromised shower valve at sea. The Jabsco 44411-series has become a standard retrofit and OEM choice across the marine industry for its reliability and straightforward serviceability.
