Hi,
I just bought a new house which had a new Megaflow and Potterton boiler fitted in around 2001. I was told by the owner that the boiler occasionally cuts out and I need to use the reset button underneath. This is seems to be happening once a day now and normally in the morning when it should have kicked in at around 6am.
I had a plumber in last week to replace the cold water feed valve on the Megaflow which was leaking, two rad valves which had become seized closed and also replaced the CH pump which had become noisy (£180 for four hours work and aall parts.
I also have a dripping overflow outside which I believe comes from the Megaflow. The plumber carried out the procedure to reinstate the air gap as it was only reading 1 bar which cured the over flow for an hour or so but not it is doing it again and I am on a water meter! The overflow was still dripping when we had drained the CH so it must be on the hot water side of the system. I have today repeated this twice and the same thing happened again and there seemed to be aallot ofwater discharged on the second attempt which makes me wonder if there is a problem with the Megaflow iits self asthere was just 5 mins between attempts.
Can anybody please offer any advice or tell me if they think these two faults are related at all. I initially suspected the overflow was causing a loss of pressure and hence the thermal cut out was kicking in on the boiler but am less sure now.
The plumber has said he will look at the boiler separately and perhaps replace the tthermal cutout. He will then replace the expansion relief valve or the entire cold water combination valve at the bottom of the Megaflow
Cheers
