On the Job
- Bath and kitchen upgrades
- Pressure and flow corrections
- Tankless and tank heater maintenance
A direct-body water-pressure regulator valve that limits downstream pressure to a factory-set 50 PSI — a protective threshold for residential fixtures, washing machine valves, and ice-maker hook-ups in systems that see city-supply spikes above 80 PSI. The inline NPT body threads onto a 3/4 in. or 1 in. cold-water line using standard pipe-dope or PTFE tape, and an integrated stainless-steel diaphragm isolates the spring from the water stream so sediment in aggressive supply water doesn't score the seat over time. A pressure-test port downstream lets you confirm setpoint during rough-in, so there's no guesswork when the inspector arrives.

Water Pressure Regulator Valve
Product Overview
A direct-body water-pressure regulator valve that limits downstream pressure to a factory-set 50 PSI — a protective threshold for residential fixtures, washing machine valves, and ice-maker hook-ups in systems that see city-supply spikes above 80 PSI. The inline NPT body threads onto a 3/4 in. or 1 in. cold-water line using standard pipe-dope or PTFE tape, and an integrated stainless-steel diaphragm isolates the spring from the water stream so sediment in aggressive supply water doesn't score the seat over time. A pressure-test port downstream lets you confirm setpoint during rough-in, so there's no guesswork when the inspector arrives.
Key Features
- Factory-set 50 PSI — protects fixtures rated to 60–80 PSI from surges
- Inline 3/4 in. or 1 in. FNPT body — installs on cold-water supply only
- Stainless-steel diaphragm — isolates spring from water, resists sediment scoring
- Pressure-test port downstream — verify setpoint at rough-in checkout
Why You'll Love It
- Engineered for real residential and commercial water pressures
- Compatible with standard U.S. fitting sizes — minimal adapter hunting
- Ships from our U.S. fulfillment center within 1-2 business days
- Backed by a 30-day return policy if it's not the right fit on arrival
Ideal Applications
Installation & Usage
- Shut off water at the nearest isolation valve before starting install.
- Apply PTFE tape clockwise to male threads — 3–5 wraps for potable lines.
- Tighten fittings hand-tight, then an additional 1/8 to 1/4 turn with a wrench — no more.
- Pressurize slowly and check for weep points before closing the wall or vanity.
What's Included
- Water Pressure Regulator Valve — 1 unit as described
- All connecting hardware and adapters included (see spec sheet for sizes)
- Installation instructions compatible with U.S. plumbing standards
- Shipped flat-rate via USPS Priority Mail
Care & Maintenance
- Flush aerators and shower heads monthly to prevent mineral buildup.
- Test pressure regulators annually — downstream pressure should hold within ±3 PSI of setpoint.
- Descale tankless heat exchangers once per year using the SKYSHALO kit for consistent flow rate.
- Inspect leak alarm sensors quarterly and replace 9 V batteries annually.
Technical Notes
- Setpoint: 50 PSI factory calibrated — field-adjustable if supply pressure exceeds 80 PSI.
- Minimum inlet pressure: 20 PSI. Do not install where inlet pressure is below threshold.
- Install on cold-water side only — do not use on hot-water or boiler lines.
