    New stat, banging & bubbling?

    best pics i could get... What has been used... I'm guessing another flush & another treatment of the above would not be a bad idea? Cheers.

    New stat, banging & bubbling?

    Just bumping this up to see if i can get any more advice, i've been working away from home for the last month or so & just home for the weekend. I've been in the loft & there is water coming out of that vent, and when i sit next to the fire every now & then there is a hiss, like a drop of...

    Soil pipe to sewer leaking

    Hi, thanks for the reply, i would like to try the second option, the only issue i have is that as seen in the pic below, half of the soil pipe is still surrounded by cement, and i'm worried about chipping it away & damaging the clay pipe. My main worry if i dont do this is that i do a repair...

    Soil pipe to sewer leaking

    Hi all. We moved into our 1960's semi in august, and noticed a nasty smell in the bathroom, which we thought was down to the air bath that was fitted, it all looked dated, so we decided to bin the lot & get a new suite etc. Smell remained. Fitted a new aav, smell remained, though a...

    New stat, banging & bubbling?

    Problem with the pump, its been fitted in a way that you cant see the front of it, i will try and get some pics of what i mean, its built inbetween all the pipework in the side of the chimney breast, slightly annoying so i dont know what its set on! Will look into magnaclean, is it an...

    New stat, banging & bubbling?

    Hi, sorry its been a while, yes i did that & it was wet. Another part of the puzzle, we have had the dining room plastered & they removed the rad so they could do the full wall. On removing it & tipping it up outside to drain it, there was a thick black sludge that came out of it, which...

    New stat, banging & bubbling?

    Off the top of my head its a baxi barricuda, but i cant remember the rest, will get the wife to dig out the paperwork and will report back. So it may not be since ive changed the stat, more likely to be the cleaning of the system thats caused it? Can't win! Leave it, it'll break, clean it...

    New stat, banging & bubbling?

    Thanks for the reply, yes its a honeywell dt90e non programmable room stat, i've fitted the honeywell st9400c which is set to miniprogrammer mode. From what was talked about earlier, i thought if there was a way of delaying the pump shut off for a few seconds, the residual heat would still...

    New stat, banging & bubbling?

    Making more banging noises again. Is there a way of delaying the pump shutting off a few seconds after the boiler stops? I cant understand how the old 1970's stat allowed this, but the new digi one does not? Thanks.

    New stat, banging & bubbling?

    New stat, banging & bubbling?

    Ok thanks, i will turn it down, is there a rule for what it should be on? Ive not changed it since we moved in. Think its on 4. I am right in thinking this is the numbered dial on the fire? One to start the fire & set the level, this one (numbers 1-5 on it) and there is also a small grey knob...

    New stat, banging & bubbling?

    So the new stat is shutting the pump off quicker than the old one? I did notice there were three terminals on both old & new stats, they are both honeywell, the old one was wired up to a & c, where the new one is wired up to a & b. I checked both manuals and i cant figure out why the old...

    New stat, banging & bubbling?

    Hi all, we have an older back boiler in our house, it did have a non digi stat but i have changed it for a digi one, checked the wiring and its ok. Odd thing, now every time the heating gets to temp & clicks off, the boiler bangs and bubbles can be heard from the boiler and going into the...
