just need some help I replaced the diaphragm and the pin on my potterton 30he due to a leak but there is still a small leak when ever the pin comes out to push the chip. Can anyone give a reason why. Thanks
I have also changed the gland nut but there is still a drip coming from the hope where the pin comes out from. Any ideas I don't want to change the whole diverter valve.
It's always simpler to change the whole thing (well, the differential assembly - you don't need the whole diverter valve), saves lots of faffing and they're not exactly expensive (about £40 from memory)
