Shurflo by Pentair Pressure Reducing City Water Entry - Wall Mount - Chrome

The Shurflo by Pentair Pressure Reducing City Water Entry Wall Mount in Chrome combines a diaphragm-design pressure reducer and integral check valve in a single compact unit. This combination water entry device is engineered to protect plumbing systems and appliances from the high-pressure surges common in municipal water supplies, safely limiting incoming pressure to 50 PSI while maintaining full compliance with applicable check valve code requirements.

The unit features a 3/4" GHT (garden hose thread) female swivel inlet, accommodating standard city water supply connections, and a 1/2" NPSM male outlet for downstream distribution lines. The diaphragm design prevents water hammer and pressure-related damage to water heaters, filters, and fixture valves—a critical consideration in RV, marine, and off-grid installations where pressure regulation directly impacts system longevity. Chrome construction offers corrosion resistance suitable for both indoor and protected outdoor mounting locations.

This wall-mount design serves RV systems, mobile homes, marine vessels, and residential properties where incoming water pressure exceeds safe operating limits. It's particularly valuable in areas with municipal systems running 80+ PSI, where unregulated pressure causes premature appliance failure and water waste. The integral check valve eliminates backflow, a dual function that simplifies installation and reduces the number of separate components required.

Pressure regulation in water systems is foundational to system reliability; undersizing or omitting a regulator in high-pressure environments is a common installation mistake. The Shurflo by Pentair unit meets or exceeds industry standards for check valve performance while delivering the pressure-limiting function required by code in many jurisdictions.
