Potterton performer 24 leaking differential pressure valve

[Locky123]

Hi all. I need a bit of advise. About 9 months ago my combi boiler started leaking. I took the cover off and noticed it was coming from the pin that that operates the microswitch on the differential pressure valve/ flow sensor. So I popped down to my local central heating place and replaced the whole valve. Now it's leaking again from the pin! do I need to get the whole new assembly again or will a replacment diaphragm fix this problem?

get a new one and take the faulty one back for a refund

All it needs is the gland nut that the pin passes through. 5 minute job

Probably just the minute 'o' ring that the pin moves through. This comes with the diaphragm kit.

As corgi says though take it back under warranty, you didn't need the whole thing in the first place!
