    Concealed shower - hose connection leaking

    Hi all, Wish I had X-ray vision. My customer has an old concealed shower valve, with a concealed shower hose connection. There is a dribble from the plastic housing around the shower hose connection (it's not the rubber sealing washer/etc on the hose). So maybe a crossed thread on the hose...

    Kitchen sink overflow

    Hi all, Has anyone come across a kitchen sink overflow that would fit a ceramic sink? They all seem to be made for stainless steel (the one I picked up from the merchant didn't have threads long enough to fix through the overflow hole). Thanks Jennie

    Gas fire not fixed to wall????

    Hi all, I'm puzzling over a gas fire Valor Homeflame. (I've fixed/serviced quite a few gas fires over the last five years, but am still learning). Every gas fire I've so far come across has been fixed securely to the closure plate/back wall, so it can't be accidentally pulled out forwards...

    Changing unvented cylinder immersion element

    Hi all, I"ve got my G3 unvented. Customer wants an immersion element changing. Access is limited - once I get into the cupboard, and I do my electrical tests it hopefully might just be the stat that needs swapping. However, if it is the element... words of advice and tips would be...

    Tapping noise under bath - a leak???

    Not a bath fitted by myself (I'd never tile it in for a start)... Customer: "We think we may have a leak under the bath. When the bath is emptying from full to half full we can hear a tapping sound- but that’s the only time. If the bath is only full to a shallow amount, or using the shower...

    Repressurise white expansion vessel

    Hi all, I've got my G3 card. First time I've attempted to re-pressurise the white, expansion vessel above an unvented cylinder. I first turned the water off, ran the taps to relieve the pressure. The vessel (it was flat). I managed to pump it up to 1.2bar with no issues. But then it was...

    Plastic-coated copper gas pipe???

    Hi all, I came across some 8mm copper pipe /plastic coated under a gas fire today. I haven't seen this before? Is it OK to be there? (It was put in by a reputable firm local to me, whom I trust, though I'd like to know what it is). Thanks all, Jennie

    re-routing gas fire pipe

    I'm due to fit my first gas fire (been servicing them for a while, but not yet fitted one). The previous fire's 8mm pipe runs from the right hand side of the chimney opening. Quite possibly, the new fire will take a side entry pipe. However, I'm curious - if I need to re-run the pipe, so it...

    Green pipes?? Sticky residue?? WTF??

    Hi all, I did a LGSC today, on a 1-year-old Worcester combi. Pics attached of the flow and return pipes to the boiler, coated with green powdery but dry residue. And also the pipe tray/cover, which had a sticky green residue. No other issues anywhere. But because it's just the central heating...

    how to set bypass (the old, red gate valve type)

    Hi all, My customer has a gatevalve/bypass off the primary flow into his cylinder. He has fiddled with it (I think he was trying to turn off the water, and got the wrong valve). How best to set it up? I'll have to check to see if the system is on a three-port or two-port valves (if it's...

    Gas leak on fire (after the gas valve)

    How far do you all go during servicing to test for leaks on gas fires? Up to the gas valve is easy -- drop test/ LDF on joints. But I had a gas fire this week, leaking from where the control 'pusher' goes into the gas valve. Visually it looked OK. But after smelling gas while using the fire...

    Anyone seen one of these plastic couplers on WC before?

    Hi everyone, I'm in the process of fixing an old Twyfords WC. It is a close-coupled model, though with an unusual plastic elbow between the cistern and pan. See pics. Anyone know if/where I can get a new elbow? Thanks for your advice, Jennie

    upstairs rad on (when heating off)

    Hi everyone, My customer has an unvented cylinder, with two two-port valves. At night, she's noticed her bedroom rad (the rad nearest the cylinder) stays on when heating is turned off. The hot water in the cylinder is the correct temperature (i.e., not overheating, so cylinder stat and...

    radiator stays on (even when central heating off)

    Hi all, I'm in the process of flushing out my parents central heating system (using F3 cleaner for a few days, then flush clean). A day into the clean, we noticed the bathroom and landing radiators were coming on intermittently. The system is an old semi-pumped gravity system, with...

    drill hole into cast iron pipe?

    Hi all, I need to re-route two pressure relief pipes (one from a combi, one from an unvented cylinder). (I have my unvented qualification). I'm going to run them both into a tundish, so there'll just be a 22mm pipe to re-route. Pic below. An extension was done, and pipes are being dealt with...

    old blue plastic 15mm pipe with glued joints?

    Hi all, My customer would like new kitchen taps. The hot is piped in copper. But the cold is piped in an old, blue plastic 15mm pipe with glued joints. A previous plumber has warned her the pipe is old, cheap and brittle, with a high chance of cracking and leaking. To change the tap, he'd need...

    Tips for Main water heater service

    Hi all, I'm due to service my first Main water heater next week. I haven't taken one apart before, so I'm a bit apprehensive. The boiler is two years old, but the flame picture has a yellow tinge, so a good clean is in order. Most of it is straightforward enough - until it comes to the funny...

    To bung or drain down?

    Hi all, I'm due to change a lock shield on a rad. It is a fairly large house, and the rad is on the ground floor. Gravity fed. Two-floor house. In theory, if I put bungs in the CH vent and supply pipes, the water should be held in the system with only a few drips while I swap the valves. Is...
