    Blocked cylinder circuit?

    Had a similar arrangement on our current property when we moved here 4 years ago. Normal primary coil was plumbed into an oil Rayburn, and immersion hole coil like yours was connected to primary from pressurised oil burner boiler via 3 port MV. Have since got rid of Rayburn and primary from...

    Stick to what you know best

    If you use PTFE tap on a compression joint, it goes around the olive, not around the threads. There are instances where you tape threads, but standard compression joints aint one of them.

    Duel system . stove gurgling!!

    Dual boiler primary water system will probably not circulate effectively without a neutraliser installed. Have seen some sysyems where heated primary water from one boiler goes to back boiler of unused stove and that heat simply dissipates up the flue. If you got gurgling, then you may have...

    Smelly hot water . Why?

    Drain it, run some clean water through, enough to empty cylinder. Milton Fluid a safe bet, as used for baby feed stuff. Might leave a bit of chloriny tang for a bit, but not unsafe if mixed in the correct proportion as per directions. I use Milton solution when servicing private water systems...

    Smelly hot water . Why?

    Recently attended a newly renovated and replumbed property on private water supply (spring, not borehole). Low pressure to house, so 2x storage tanks in loft. So-called plumber hadn't bothered with lids, hence a nice soup of dead flies and bats feeding both cold and DHW outlets. And the only...

    Suspected leaking pipe in concrete floor

    If pipes have corroded due to being buried in concrete, then be prepared for them to be fragile when exposed. You need force to break concrete, but corroded pipes dont like force. If lowering pressurw issues indicate pipe leak , then best advise client of worst case scenario. Dig up floor...

    Burnt speedfit fitting-is it a problem?

    Likewise, looks more contaminated than burnt. They tend to bubble up if burnt. If unsure of it, they are not difficult to undo and replace if you can get hands on. Simply drain down CH. Slacken nuts on fitting and remove. Fit like for like, and make sure pipe has inserts fitted. Recently...

    Plumbers of UK, would you mind answering a few questions for my research assignment

    Word of mouth. Means customers have a good reference point, and can sometimes view your previous work. Social media can encourage a drive to the cheapest. Having seen the results of 'cheap' plumbers, and having to rectify their crap work, its no longer cheap for the client. On TV £100k House...

    Chased pipes into wall.

    Having just spent 1 1/2 days locating and replacing leaking pipes buried in a plastered wall and also into sub-floor screed, my vote is deffo for sleeving or ducting. The copper pipes I dug out were corroded to hell. Also agree, 1 or 2mm of gypsum plaster will crack up.

    Mains stopcock stuck

    Find out where the external isolation tap is first. Could be within your boundary, but most likely on pavement or road. Sometimes isolates more than one property, so check with neighbours. Be prepared for outside tap chamber to be full of crud if not touched for some time. If it is inaccessible...

    Oil Boiler not heating hot water after draining system.

    Airlock likely. Check for air bleed valves. If none there, crack the highest joints on primary circuit to let air out. Dont undo fully, just enough to let air out.

    “Ticking” motorised valve

    If your valve is the type where you can remove the head unit, comprising the gearbox and motor, then get a new head to match yours. Note some motorised valves allow removal of head without draining down, some don't. Wiring from head unit connects with terminala in junction box which should be...

    Advice please on new loo fitting

    Flexi under stress. Iso valve fitted to pipe not cleaned of paint. Iso screw not perpendicular to wall. Generally untidy finish Didn't even bother to check for water tightness before buggering off with your cash. Not really a pro job, is it?

    Suggestions on how I should correctly seal this value

    Before applying PTFE to threaded joints I connect the joint counting how many revolutions until it comes to the end. Helpful if aligning taps, etc. Apply PTFE and if there is enough on, the joint will lock up before maximum revolutions reached. On deep-cut threads, it may be be wise to try on...
