    What to do with dismissed loft cisterns?

    Yeah, they'll be full of Limescale most likely, which will dry then flake off. If they can come out easily enough, maybe make a little water feature in the garden or something? Also, don't take the cylinder to the tip, you'll get maybe £30/40 for it with a scrap metal place

    Can somebody please point out the issues with this installation, thank you

    I'd describe that as a sub-DIY level job to be honest. No care has been take there whatsoever. Plastic always looks rubbish where it's exposed, especially heating pipes which get hot, then go softer, then sag/contort. I installed a rad run like this once because it's what the LL actually...

    Have you ever / would you ever; Work for a Plumbing Supplier / Plumbing Wholesaler

    I worked at a large independant plumber's merchants in Essex (formally Compass Plumbing) for seven years before leaving to go out on my own on the tools. I mostly liked working there, it just wasn't my actual 'career', more a stepping stone to my career. I learned a lot and i thought it was a...

    Gas Engineer Software

    Just to update on this- i went for Gas Engineer Software and have found it pretty spot-on for certs, which is what i've initially used it for. I'm going to start using it for invoicing too, and quotes, it looks quite easy to turn a quote into an invoice once you've actually done the job. I'm...

    Vaillant VR10 with a vented cylinder?

    Hi, I was hoping to replace an old system boiler with a Vaillant Ecotec Exclusive 627 system boiler, thats the one with the diverter valve so no need for zone valves, controling it with a V-Smart and a VR10. I've spoken to Vaillant Tech and they said you cannot use the VR10 with a vented...

    Heatloss through internal ceiling

    Hello, i'm doing some heatloss calculations, going by a fairly old plumbing book. The formula for calculating heatloss would be Surface Area x Temp Diff x U-Value = Heatloss My question is, when calculating the heatloss through a ceiling, so downstairs to upstairs, the temp difference would be...

    Trade MAstermind webinaar

    In case anyone else searches for this- I sat through their initial 'free seminar' (sales pitch), and it had all the markings of what's talked about a lot as 'The Fake Guru' industry. They exist across many domains, but all have the same markings- an overpriced intensive course with vague...

    New rads added - last one cold

    You seem to have got it sorted, but for future reference, try just turning ALL other rads off, and put heating only on if it's a conventional system, just put the heating on if it's a combi, and so the full force of the pump is pushing through that one rad, that should hopefully clear any air...

    Room Thermostat: Would I Benefit From Optimum Start/Stop?

    It's very hard to calculate, if you've got a smart stat you can maybe experiment. Will it cost more than heating the house to 16 then sitting there cold after that? Yes. Will it cost more than heating the house to 18/19 say, then coasting down to 16 or less by the time you go to bed etc? Maybe not

    Room Thermostat: Would I Benefit From Optimum Start/Stop?

    I'd say it's a worthwile feature, but not so much in the way that you're using the heating. All optimum start does, is bring the heating on when the thermostat calculates it needs to, in order for you to be warm when you programme it to. I.e. if you set it to be 18 degrees at 7am, it'll bring...

    Vaillant System Boiler With Additional Pump

    Hi, thanks for the reply, that did cross my mind but it's a little tight for space where it is, it might squeeze in but I wasn't sure if that was necessary and just an additional pump would do?

    New UPS3 pump too powerful ?

    A simple thing i'd probably check is the locksheild valves on the rads. I've installed a tall column rad right next to the boiler before, and it was quite noisy, i turned the locksheild right down until the noise went, it had to be almost off. I've found some column/designer rads are...

    Vaillant System Boiler With Additional Pump

    Hi, i've got a job with a Vaillant Ecotec 630 system boiler, and i don't know the full history but the house has definitely been extended significantly since the boiler was installed. There's now 21 radiators/towel rails. It's getting to temperature, but even after balancing, it's not heating...

    Gas Engineer Software

    Hi, i'm looking for some gas engineer software primarily to produce gas certs on, i was previously using one called Gas App UK, which was ok enough, but they've switched to a paid subscription model last week without warning , and looking at a few of the others it's probably not the best one if...

    How Much Trac Pipe Tape?

    Hello, I've got a job where all 24 Trac Pipe connections in a meter room are unwrapped with protective tape, and i've no idea howe many rolls of tape that will get through as i've only used the stuff once. Just after a rough guide really, some pipes have had the sleeve trimmed back a bit more...

    Powerflushing a system with a Powermax

    Hello, I have a job with a Potterton Powermax system that is badly clogged up with sludge/rust from several leaks/ignored problems etc. I want to powerlush it to try and solve some of the problems, and I just want to get clear in my head how to go about this. I guess i'll disconnect the...

    Main Eco Elite Sump Gasket

    Hello, I've got a Main Eco Elite combi with a gap in the sump gasket (pretty sure that's what they call the part) so POCs are escaping, so needs to be replaced. Has anyone got any idea how long this is likely to take? I can't work out if the hole heat exchanger needs to come out or whether the...

    Blocked Saniflo outlet pipe

    I managed to clear it by diconnecting the actaul Saniflo, and pouring drain acid down the pipe and then linking it to the shower hose and running hot water down it and it seemed to clear, but I absolutely wouldn't recommend you try this yourself as drain acid can not only be really dangerous to...

    Vaillant Ecotec Diverter Valve Repair Cartridge

    Just for future reference, i ordered it, fitted it, and all went well. So that's £10 in parts v £122.82, and took half the amount of time to fit. You do feel like you're going to break it getting it in to be honest, but just make sure you've got it lined up and gently tap it, i think it the best...
