Worcester Greenstar PRV - The EASIEST Way Without Cutting Out Any Pipes (Complete Start To Finish)

(Under 30 Minute Repair)

Reasons you might need to change the pressure release valve (PRV):

- It's continuously letting out water.

Usually this happens for 2 reasons:

1.) The expansion vessel has failed or gone flat.

2.) The filling loop has been left open so the system pressure has built up too high.

3.) (Very rare) Your plate heat exchanger has pin-holed and is allowing cold water into the CH circuit.

It's important to address the above 2 (possibly 3) reasons before repairing the PRV otherwise it will keep happening.
