Pressure Relief Valves & Regulators

Pressure Relief Valves & Regulators keep plumbing systems safe, stable, and efficient by controlling pressure and releasing excess before it causes damage. Whether you’re protecting a water heater, balancing household water pressure, or safeguarding a boiler or hydronic loop, these components help prevent leaks, nuisance drips, water hammer, and premature wear on pipes and fixtures.

Common types include pressure reducing valves (PRVs) that step down high incoming municipal pressure to a comfortable, code-compliant level; temperature and pressure (T&P) relief valves for water heaters; boiler relief valves for closed-loop heating; and point-of-use regulators for appliances, irrigation zones, or well systems. The right selection improves comfort, extends equipment life, and cuts water and energy waste.

Key benefits:
- Protects appliances, fixtures, and piping from overpressure
- Delivers steady, comfortable water pressure at showers and taps
- Reduces maintenance, leaks, and callbacks for pros
- Supports code compliance and safety best practices

When choosing a valve or regulator, match the size and flow capacity (Cv) to the system demand, select the correct set pressure and temperature ratings, and confirm certifications such as ASME, CSA, and NSF/ANSI. Look for lead-free brass for potable water, stainless options for harsh conditions, and connections that suit your workflow—NPT, sweat/solder, press, or push-to-connect. Features like adjustable setpoints, built-in or add-on gauges, tamper-resistant caps, and union ends simplify setup and service.

Installation tips: mount in the correct orientation, add shutoff valves and unions for serviceability, include a gauge port to verify performance, and route discharge lines to a safe drain. Test T&P valves regularly, flush PRVs to clear debris, and replace units that show corrosion, sticking, or persistent weeping.
