Hi all,
I could really do with some help, I've looked around the form and followed some advice, but not reached a resolution.
I moved into a 14 year old house in October 2014. The house is fitted with a Potterton boiler with and F&E tank in the loft and a hot water cylinder.
When we moved in, it was warm enough not to need to use the heating, but when the boiler was on, it was quite loud (I now know it was kettling).
Around 2 weeks in, I managed to screw straight into one of the micro bore heating pipes when hanging a curtain rail. Ouch. I really could have kicked myself.
Anyway, ended up calling a plumber to make good my damage. While looking around the system, he pointed out that he thought the pump was mounted the wrong way, I.e. the flow was in the wrong direction. Honestly, I did not think too much about it, I thought he might be wrong or wanted another job, and the hot water worked fine.
Anyway, it started to get cold and I used the heating for the first time. The first morning, I was woken by a loud banging from the rads and a gurgling sound from a few. I thought the repair had sprung a leak, but it wasn't that.
I bled the system and considerable air came out. The next day was the same, and so on.
Reading this forum, I thought it might be corrison related, so over Christmas I drained part of the system and added Sentinal X400 and left this to run for three weeks. I drained and flushed the system and refilled it with clean water and Sentinal X200 and X100.
The water that came out during the flush was milky black, but the system was drained when I had my mishap, so some of the sludge may have been removed at this point.
This has reduced the kettling but the gurgling is still there, as loud as before. Two of the rads need bleeding every day.
I now wonder if the plumber was right or whether I am missing something else. Not knowing how the system ran before, I'm not sure if I have created the mess, but I have noticed that the previous owner took other shortcuts around the house, so it is plausible that he fitted the pump and got it wrong.
Any help would be much appricated, its been driving me bananas for weeks now.
Thanks,
Ash
