Description

  • Stainless steel construction (available since 06/01/2019)

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.
