Hi I am having trouble finding a fixing that will hold firm in my wall and thought I may some useful advice here. I have a house that was built in the 80s. All the external walls have a lightweight concrete block inner skin which is covered with about 1 inch of very crumbly grey plaster...

OK, I've been trying to follow this but as someone with very little understanding of electrics I am completely lost. I may have confused the issue to begin with by using saying the pipes were earthed rather than bonded. I haven't tested the pipes in any way. The bath is a replacement and...

Thanks for your responses guys. I accept both sides of the argument. The chances of the bath becoming live are extremely low but for the sake of a few feet of cable I will get it earthed.

Sorry flameport, you posted while I was writing so I didn't see your post. Isn't there a chance the bath could become live by accident (very unlikely) and therefore needs to be cross-bonded?

Having dug around some more, it seems I definitely need to earth the bath as it could potentially become live under a fault condition.

Hi I'm installing a new bath and I'm not sure what to do about earthing it. The taps are wall mounted so there is no direct contact between the pipes/taps and bath. The pipes are all earthed. It is a steel bath so does it need to be earthed? Thanks

Sorry if this question has been asked already but I am confused. I have a selection of Floplast plastic waste pipes. I have some pipe with 43 mm printed on the side. I've measured it and it is 43 mm outside diameter. I also have some 32 mm pipe which I have measured as 32 mm INSIDE...

OK, so i checked the wiring on the transformers over the weekend and my electrician had wired them incorrectly. Each transformers had a pair of terminals for supplying 2 lamps on the 12V side and he had matched the pairs up the wrong way round (1 light in to both +ve terminals and 1 light in to...

Yes it was the same electrician. His quote was cheapest but it seemed such a simple job I didn't think it could go wrong. Lesson learnt. :oops:

OK I'll get him back. My concern was whether I should find another electrician. Clearly I am not qualified to do this work and I wouldn't try but if I have a pack of lamps with MR16 12V written on it and they have 2 straight pins which are 5 mm apart and fit in to the fitting then why would...

OK Thanks. That makes a lot more sense than his explanation and I can see the safety reasons for it now. :D

Is there more than one type of MR16 bulb though? Do they even exist or are they all GU5.3? Seems to me that if they are 12V bulbs and they fit then they should work!

Hi I've just had an electrician out to wire up some underfloor heating and think he either pulled a fast one or doesn't know what he is talking about. To save money I ran all the cables before he arrived and then he made up all the connections. I ran a 1.5mm2 cable (5 m long) from a...

Hi I had an electrician come out to fit some 12V downlights and he left without them working. I supplied the fittings below...

I have a small mid-terrace house that was built in 1995. There are 2 radiators downstairs and 3 upstairs. The biggest radiator in the house, downstairs in the lounge, only gets hot on the very top and down both sides, about 3 inches from the edges. The rest of the radiator is stone cold...

Sorry. Didn't quite understand your message. Are you saying that the green is copper carbonate not copper oxide? I'm not going to argue with that because I was only guessing. Either way, is it likely to mean that something is corroding?

It does clean off pretty easily but I was concerned that if it was some kind of copper oxide then that must mean that copper is corroding somewhere. I know it will take a long time but I don't want a pipe to burst in a year or two. Would a tiny leak cause green stuff? I thought it would...

I have just moved into a brand new house and one of the taps has a green crystalline scum building up around it. It is a mixer tap and the problem is round the cold side. I can see that it is coming from around one of the nuts where the cold inlet is attached to the mixer chamber. To be...

I want to install a 500W PIR floodlight outside my house. The only place I can put it is above an upstairs window and I want to take power from the loft. The only power the loft has is for the upstairs lighting which has its own circuit breaker in the consumer unit. That circuit currently...

Thanks, that makes sense now but I think I will find it difficult to find skirting with pattern I have, in a taller size. I will keep looking. :shock:
