Camco RV Water Heater Temperature & Pressure Relief Valve 1/2" NPT, 4" Epoxy Probe, CSA-Certified

Keep your RV water heater operating safely with a relief valve designed for corrosion resistance and reliable factory settings. This Camco valve connects using standard 1/2"-14 NPT fittings and includes a 4-inch probe that helps sense temperature inside the heater tank. Built without gaskets and finished with an epoxy-coated probe, it minimizes corrosion buildup and reduces maintenance needs while meeting CSA safety standards.

How does this valve protect my RV water heater?

The valve automatically vents water if either pressure or temperature exceed safe limits, preventing damage from excessive pressure or scalding temperatures. Its dual-sensing design responds to both conditions so one component handles two common failure modes.

• Factory set to open at 150 PSI to relieve overpressure.
• Factory set to trip at 210°F to limit dangerously high temperatures.
• 4" probe increases temperature sensing accuracy inside the tank.
• CSA certification confirms performance to recognized safety standards.

What are the connection and material specifics I should know?

Connections match standard RV water heater ports: a 1/2"-14 NPT male inlet and a 1/2"-14 NPT female outlet. The metal body and epoxy-coated probe minimize corrosion and eliminate gasket failure points that can cause leaks.

• 1/2"-14 NPT male inlet and 1/2"-14 NPT female outlet for easy swap-in replacement.
• No gaskets in the design to reduce potential leak surfaces.
• Epoxy-coated probe to resist rust and mineral buildup over time.
• Durable metal construction designed for RV environments.

Will this valve fit my RV water heater and how do I install it?

The valve is sized to replace most RV water heater relief valves using 1/2"-14 NPT fittings. Installation is straightforward for anyone comfortable with basic plumbing: drain the tank to below the valve level, remove the old valve, apply appropriate thread sealant, and tighten to specification.

• Fits standard 1/2"-14 NPT heater ports used in many RV models.
• Requires tank depressurization before removal to avoid hot water discharge.
• Use pipe thread sealant or tape rated for potable water; hand-tighten and then wrench to spec.
• Check for leaks after refilling and pressurizing the system.

How does construction affect long-term performance?

Materials and factory preset calibration reduce maintenance and support dependable operation over years of travel use. The reduced corrosion risk from the epoxy probe and gasket-free design lowers the chance of failure in corrosive or mineral-rich water conditions common in some campsites.

• Epoxy coating protects probe from scale and corrosion, preserving sensing accuracy.
• Gasket-free assembly reduces leak-prone components.
• Factory preset values eliminate the need for field calibration.
• CSA certification ensures consistent manufacturing quality and test standards.

Who this is for: RV owners, fleet managers, and technicians seeking a reliable replacement or upgrade for water heater pressure-temperature protection. Choose this Camco valve if you need a straightforward, CSA-certified relief valve with standard 1/2" NPT fittings, corrosion-resistant probe, and factory-set safety settings to help protect tanks during everyday travel and seasonal use.
