    Loud clonking and pressure dial bouncing on baxi combi.

    It was bouncing around it's 1.5ish bar so probably between 1 and 2. It was just acting like you were shaking it making the needle wobble, in time with each bang from inside. Afterwards the pressure was still good. I don't know exactly what it was at before but no obvious drop remembering where...

    Loud clonking and pressure dial bouncing on baxi combi.

    Filling loop being the two black 'taps' on the right hand side underneath? If so they are definitely turned off (I checked) - are they a part that could fail and be stuck open though? The pressure dial is (apart from when it went crazy) holding steady at just over 1 bar. Prv presumably is the...

    Loud clonking and pressure dial bouncing on baxi combi.

    Very similar symptoms to this other thread on our Baxi duo tec Combi 40 e: https://www.diynot.com/diy/threads/boiler-pressure-going-mental.304352/ I've heard it take a few times but never got to it in time, it only lasts for a minute or so. Today I heard it - sounded like someone running along...

    Planing swollen doors... do I need to paint right away?

    I think this is general atmospheric moisture, the bits in question (shouldn't) ever get direct water on them. Well, they were when they wouldn't shut but they still had paint on them :) I thought I'd got away with it as they were stable until a week back. Then winter properly arrived :)

    Planing swollen doors... do I need to paint right away?

    Ta. Will it make much difference to how quickly they absorb further water?

    Planing swollen doors... do I need to paint right away?

    The last week I've had 4 different outside doors all swell and stick. They were all painted and I've obviously lost the paint planing them to close... is it important to repaint immediately to prevent the exposed wood absorbing more moisture? It's really not a great time of year for painting but...

    Installing uPVC vertical sash windows... Cill pre-attached to frame?

    I've received 2 Spectus quickslide sash windows and was pleasantly surprised to see they come fully preassembled. This includes the 152mm cill - it is screwed to the bottom of the frame. Initially I thought that was just to hold it in place for transport, but it's fully sealed as well. I'd...

    Powered caulking gun

    Thanks, I hadn't considered the effort with much stiffer materials either.

    Flat warm roof... does the top deck require additional joists or could it screw through to the main structure?

    I'm looking to build a warm-roof on a cabin, employing rigid PIR insulation and an EPDM rubber top layer. The basic order would be, top->down: EPDM rubber sheet OSB top deck PIR boards (150mm most likely) VPL membrane (PVC sheet) boarded bottom deck (also serves as the ceiling) roof...

    Mitre acute angles

    @Notch7 so essentially pushing the piece 'lengthways' into the saw but using a backing piece to stabilise and make it safe? I might go to the hand saw for peace of mind as it's only a little bead but thanks this technique makes sense. I'll have a practice with some scrap first :)

    Mitre acute angles

    I need to cut a bead to fit into the eaves of my 25 degree pitched roof... so the bead actually needs to be cut at a pretty acute angle, on my mitre saw I'd have to go to 65 degrees which is far beyond what it can do. My basic mitre block can't either end even looking at a more expensive tool...

    Is BG HomeCare worthwhile for a problematic system?

    If they need doing they need doing, but I'm loath to spend time or money unless it does, I'd want to figure out the root cause first. Is it something one can tell visually by taking one in the garden and seeing how much crud is in there?

    Is BG HomeCare worthwhile for a problematic system?

    It is a big house so I think it was 22 in total when I had to count them all for the powerflush quote!! Several are very new but others could easily be 20 years old. I was chatting to our regular plumber on the phone whether we could remove one of the older ones and inspect it to see how full of...

    Is BG HomeCare worthwhile for a problematic system?

    Cheers @Harry Bloomfield. You are in an enviable position from my view :) Clearly there is no 'magic' to this it's a closed system with copper/plastic pipes, the boiler itself and steel radiators (they are all the modern type though some are old, no antique cast iron ones). Logically, any dirt...

    Is BG HomeCare worthwhile for a problematic system?

    We were advised to have it done as the system was filthy and causing damage. But how can one tell if the cleanse was not done well, or something else is to blame... what sort of things can be missed when doing a flush? I am imagining things like missing a radiator perhaps - everything looks good...

    Is BG HomeCare worthwhile for a problematic system?

    Thanks, just on that topic for future what should good practice be with adding additional inhibitor? Presumably the odd re-pressurisation is OK but if you replace a radiator or whatever you need to add more water back. Is there a rule of thumb here when and how much inhibitor to add? Thanks...

    Is BG HomeCare worthwhile for a problematic system?

    Typically every few months. The plumber's already established that's not the issue - well at least not this time :) We check it regularly but I actually can't recall the last time it dropped since we had something else fixed a few months back.

    Is BG HomeCare worthwhile for a problematic system?

    Whenever it needs it, we check regularly but it holds pressure well and typically doesn't need topping up often. Given I up up there restarting the boiler about twice a day it gets plenty of attention. As I said the plumber suspects a blockage leading to overheat based on past history but hard...

    Is BG HomeCare worthwhile for a problematic system?

    What kind of underlying problem could cause recurring sludge after a proper flush? I know the company took water measurements before/after and seemed happy but I have no way to know if they did it properly. They seemed fairly thorough in terms of accessing all the radiators which leaves me a bit...
