    Adding external light

    You mean the ceiling light? Sure - but I thought it would be neater to have a junction box where the wire from the light meets the wall.

    Adding external light

    OK, thanks. I'll probably add one then, but in a slightly different location to avoid turning off accidentally. Ahh, that's OK, the ring from the light comes across the ceiling and then down next to the light, so I could add a junction box for my spur here? Is there ever a good reason to...

    Vaillant combi boiler problem - heating always on.

    Sanivite installation - solvent weld waste

    Hi, Great, thanks for this. I did take a look on Youtube and saw some videos, looks simple enough. Seems like the trick is to make sure the ends are straight, deburred and clean - common sense really. I can't remember how the trap connects to the soil pipe, but I should be able to sort it...

    Sanivite installation - solvent weld waste

    Hi, I'm planning to put my washing machine in my cellar and will need a Sanivite to pump the waste water out. The washing machine will be directly below its current location so it shouldn't be too hard but I have a couple of questions. 1. The manual says that I should use solvent weld...
