Cash Acme Back Pressure Relief Valves
|British Gas Approved||No|
The cash acme back pressure relief or boiler relief valves are usually installed in multi appliance, oil pumped ringmain systems. They are used to maintain a constant pressure on the positive side of the pump whether all appliances are in use or not.
If you’ve noticed that a boiler is suddenly letting out steam, it’s most likely coming from the boiler relief valve, also known as a pressure relief valve and needs to be replaced.
If you need help on how to identify if your boiler relief valve needs replacing, take a look at our guide here.
