    How to remove seized tap backnut

    Thanks, Undertrained, snowhead and PETE 123. Panic over! In the end, I drilled into the nut, fully intending to crack it open, but used too big a bit (4 mm) to gain leverage. However, it did weaken the nut's grip enough to allow it be slowly unscrewed with what leverage I had. Some damage...

    How to remove seized tap backnut

    Hello all, Can anyone suggest a good way of relieving this hot water tap of its backnut? The nut's quite firmly seized to the thread. Have so far tried scraping the crud out of the nut then spraying with WD-40, tapping with a hammer, applying with a heat gun and, of course, brute force...

    What power cable for immersion heater?

    Yes. It's the only heater. 2.5 mm² it is. Thanks very much, Murdoch.

    What power cable for immersion heater?

    An easy one... The power cable from my immersion heater controller to the heater itself needs replacing. It's been stripped back so many times over the years that it's getting too short. Can someone qualified tell me exactly what cable to ask for? From what I've read, it would be a three-core...

    Replacing "short wire" in immersion heater

    Thanks, ShaunCorbs, Murdoch and Gasmk1. That sounds fairly conclusive. It's possible I could've nudged the wire when adjusting the thermostat. It's frustrating because every time I wire up the thermostat, I always make sure it's screwed tight. Don't know what else I can do. Not sure, but I...

    Replacing "short wire" in immersion heater

    OK. Thanks, both. As I found it, the wire was fried (the insulating sheath was burnt and crumbled away) and was either free or hanging by a strand (it came away from the terminal easily). When tested, the heater shows the correct resistance (just under 20 Ω) as does the thermostat. The...

    Replacing "short wire" in immersion heater

    Thanks, but again more information would help. Trekking up to Screwfix in the middle of winter at the height of a pandemic, buying a new heater and going through the rigmarole of fitting it is easier than soldering? There's no doubt it won't be as good. The question was: is it safe...

    Thanks. Why do you say that?

    Replacing "short wire" in immersion heater

    Hi, This morning, I found that my immersion heater had stopped working. The short wire that runs from the thermostat to the live terminal of the heater had fried (or at least its insulation did) and disconnected from the terminal pin. Although I've scavenged a replacement wire from an old...

    Immersion heater: copper, Incoloy or titanium element?

    Don't have a multimeter but did replace the thermostat with a new one. No heating even though there was voltage at both terminals of the thermostat. Looking again just now, the site of the blow-out seems to be the heater's neutral terminal in the boss. Taking the thermostat apart, there's no...

    Immersion heater: copper, Incoloy or titanium element?

    It failed after three years. Don't know the reason yet as I've not had chance to drain the cylinder. The thermostat is fused with black scorch marks.
