INSTALLATION
DIY-friendly; drain boiler pressure before removing the old valve.
PRO TIPS
- Gaskets aren't always required - as the valve and boiler expand with heat, small leaks at the junction typically seal themselves. As a rule of thumb, if your old valve had a gasket, install a fresh one for added assurance.
- Measure the outside of your existing valve's male threads (should read about 1/2") before ordering to confirm fitment.
