Webstone 44443pr Tankless Heater Service Valve Kit 3/4 Ips

Product Description

The WEBSTONE 44443pr is a tankless water heater service valve kit designed for 3/4-inch IPS connections on both the inlet and outlet sides of the heater. This kit includes integrated isolation valves and a pressure relief function, allowing a technician to shut off water flow and service the heater without draining the broader system. It is part of the Isolator E-X-P E2 series, engineered for the specific service demands of tankless water heater installations in residential and light commercial applications. Licensed plumbers are the primary installers of this kit.

This valve kit is suited for tankless water heater installations where routine service access is required. The 3/4-inch IPS connection size accommodates the standard supply and return port sizing found on most residential tankless heaters. The built-in pressure relief integration supports code-compliant installations by combining multiple service functions into a single compact assembly, reducing the number of individual fittings required at the heater connection points.

Key Features

• 3/4-inch IPS inlet and outlet connections match standard tankless heater port sizing
• Integrated pressure relief function supports code-compliant installation
• Isolation valve design allows heater service without full system shutdown
• Isolator E-X-P E2 series construction for tankless-specific service demands

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off the cold water supply and relieve system pressure before beginning work. Ensure all threaded connections are properly sealed with approved thread sealant or tape rated for potable water systems. Do not overtighten IPS fittings, as this can damage valve bodies or distort sealing surfaces.
