I have a vaillant turbo max boiler which loses about 1/2 bar pressure over the space of 3 weeks. I have checked and found that the PRV outside is leaking. The expansion vessel appears to be fine (there was no abnormal pressure rise when the heating was on) so I don’t think this is what’s causing the PRV drip. No other leaks appear to be present around the house/radiators etc.

I’ve also tried to flick the PRV knob a few times to try dislodge any debris, but the leakage outside continues slowly. I’m assuming the valve is knackered.

I’m planning to install a new valve. I was reading online that I just have to drain down the boiler, and isolate the CH flow/return pipes under the boiler, and then remove the valve.

However, some people have said that, when messing with the isolation valves, if they haven’t been touched for a very long time, are prone to leaking.

Is this correct? If I do encounter a leakage at those valves when isolating, what can be done to stop this, as they are just small screws?

Thank you for your help!

Turbomax isos are generally ok. However, If they do leak, the only option is to replace them.
