Hi Some years back I had a Worcester Bosch 30CDI boiler installed and this was ideal for the size of house and when the family lived at home and for when they all come and visit at Christmas. Now there's just the two of us and we only heat the rooms we use and a hot water tank. Consequently...

The instructions that came with my bathroom fan (Marley NDX100T) say that it must be isolated with a double pole isolation switch. The wiring diagram shows the pull switch, bathroom lights and fan all isolated with this switch and this is how it has been wired. The instructions are...

Having recently discovered that my gas supply is not bonded I have been investigating just what IS bonded in the house. The house is old and (from what I've read on here) I think my supply is TT, there is an earth spike and an RCD. I have found a bonding connection to my cold water supply...

Hi, I've recently created a shower room and the electrics are being inspected in a couple of days. There are five pipes entering the room, hot water, cold water, central heating flow and return and the shower cold feed from the header tank. Because the floor has been tiled I've bonded...

Had one about four years and it's done me well. Now making a rattling noise and I suspect the bearings are going. Are these things serviceable or should I just get another one?

I've fitted a new toilet and connected it up, via a couple of feet of plastic pipe and an adaptor, to an old clay foul pipe. The floor round the toilet and the floor over the new pipe leading up to the clay pipe has now been tiled. The clay pipe is in two sections a straight section about...

The lighting circuit in my house has no earth. I want to install two class 1 lights in a new shower room. In the loft above there will be the cold feed to the shower. If I connect an earth from the light to this and bond the cold feed to the hot feed and bond the hot feed to the central...

Prior to using it in anger I've been doing some experimenting and can't seem to get it right. I'm attempting a through crimp on 1mm sq cable. I'm using a red butt connector and a ratchet crimping tool. However a good tug pulls the wire out, that can't be right. How much insulation should I...

I'm creating a shower room - washbasin, toilet, towel rail, radiator and shower. I'm half way through, washbasin, toilet, towel rail and radiator installed with half the room and floor tiled in porcelain tiles. The far end of the room is to have the shower. Problem. I now realise that the...
