What does a pressure relief valve do? | Viessmann

Without a pressure relief valve (PRV), your boiler would frequently over pressurise and this could cause it to shut down or present a fault code on the screen. The PRV helps to control the pressure within your boiler, ensuring that the level doesn't become too high. If you're wondering how a PRV works, or how to fix a broken one, then you
