    Seal hole in radiator

    I have a heated towel rail with an imperial size radiator as a middle panel that has got a pinprick hole in it. I do not want to replace the towel rail which is brass and cannot source a replacement radiator so is there anything I can use to seal the hole? Thanks

    Saniflo toilet

    Another question... I have asked a plumber whether I can install a toilet in a room where there is no easy access to a soil pipe so he has suggested a saniflo type toilet. What are opinions of the plumbing cognoscenti?

    Brown scale in toilet

    We live in a hard water area at the end of a small cul de sac which is on a mains water spur that terminates outside our house. When we first moved in the water company used to flush the mains once a year to clear out any sludge - it was dreadful the first time, really brown, but subsequently it...

    Immersion heater - leave on or timed?

    Thanks - now totally confused since both options seem logical. 1. Leave it on all the time and the water doesn't get so cold so less power is needed to heat it up OR 2. Put it on a timer and the heater lasts longer and you're not heating water when you don't need it I guess the...

    Thanks to several forum members I have successfully? replaced an immesion heater in my daughter's flat. I would now be interested to have opinions as to whether it is more economical to leave the heater on permanently or use a timer? Regards

    Water cylinder - sacrificial anode

    Kevplumb If it was an expansion pipe and it's now disintegrated will this cause trouble? However, I cleaned out the tank last night and it certainly seemed that the bits were of a solid section i.e. not a hollow tube. Do you think all the bits formed a coil that was connected to the small...

    Water cylinder - sacrificial anode

    My daughter's flat has a combination cylinder and in the top section there is the remains, in several bits, of what looks to be a heavily calcium encrusted rod or pipe bent into a hoop - it looks as if it was about 12" - 15" in diameter orginally. I've read somewhere about sacrificial...

    Immersion heater replacement?

    Nemo & others Thanks for the advice - will try heating up the boss. Still a bit concerned at the loss of the sacrificial anode in the cylinder - will the new immersion heater immediately start to corrode and quickly fail?

    Immersion heater replacement?

    My daughter's flat has a combination water cylinder with an immersion heater. The heater does not work and needs replacing but so far I have been unable to unscrew the old unit. The spanner I'm using carries a warning about not using undue pressure as the cylinder may distort or even break...

    Have to replace combi boiler - which one?

    Wilhelm/Oilman Thanks for the advice. The boiler is leaking from underneath but I can't see from where so possibly it's the water jacket? I have experience of amateur plumbing but nothing with boilers but am willing to give it a go if it's fairly straightforward. Do I just dive in and...

    Have to replace combi boiler - which one?

    I have a small cottage with 8 rads (9 if a double is counted as two) with a Grant 90 combi boiler that has given up the ghost and has to be replaced according to a well known and respected local heating engineer. When the boiler worked we only got a very slow flow from the domestic hot water...

    Combi boiler shows zero pressure

    I have a Grant Combi 90 boiler and the pressure gauge keeps falling to zero when the boiler is not providing hot water - when it is heating then the pressure rises to normal. I used to open the valves and top it up but the pressure falls again very quickly so I gave up and it doesn't seem to...

    How to replace an immersion heater

    I believe my daughter's immersion heater has failed and may need replacing. Can I just disconnect the electricity, turn off the cold water supply and remove the old unit or do I need to do anything else? Thanks

    Adding lights to outside circuit

    I've been found out - I am not sure they are wired in series - I just used the term I have heard to describe how I have seen the cable connected! I belive Securespark's 'sequence' description is correct i.e. Mains to Switch, Switch to Light1, Light 1 to Light 2, Light 2 to Light 3...

    Combi - pressure relief valve

    Hi The red 'target' needle on the gauge is set to 1.1 bar and I re-pressurise to this level. The pressure rises to over 2 bar when the boiler is burning and then it falls to zero when it is off. The original pressure relief valve had a 'relief' pressure of over 3 bar but the replacement...
