Frequenty asked questions about plumbing and electrical work.


Q : I have fitted my outside tap, which was my first attempt at plumbing. Everything went well, except when I tried to get the tap to line up straight. The tap thread is all the way into the wall back plate, but the tap is pointing sideways.

A : You have a very common problem, in fact it's usually what happens when an outside tap is being installed (not just with our taps, all outside taps from all suppliers). Generally, it's pure luck what angle the tap ends up when it is tightened . If you think about it, the tap could be fitted with the pipe coming down a wall as well as from below, so it's impossible for the manufacturer to know what way the product will be used. The best bet is to use some extra PTFE tape and don't worry about the last part of a turn. It's the PTFE tape that makes the water tight seal, not the tightness of the joint. If you need any help, you can ring us on 028 91271880 (during working hours).

Q : What's the difference between pipe and tube ?

A : The main difference between pipe and tube is how the size is described. Pipe has a "nominal size" based on it's inside diameter. Tube is described by it's outside diameter. Though plumbers often use both terms to describe the same thing, for example "have you got any 15mm copper pipe ?", when they really should say "have you got any 15mm copper tube ?".

Q : The thread on my plumbing fitting is 3/4″, but it measures 1″ with a ruler ?

A : Plumbing threads are made to a British Standard and are measured a special way. It can be a bit confusing, have a look at the BSPT link at the bottom of the page for more infomation.


Q : Hi I connect the blue wire to the N and the brown wire to L , it does not work, please can you advise ?

A : Much as we would like to help, you must realise that electricity is dangerous - it really is possible to kill yourself or someone else if you don't know what to do. We don't like to offer any advice on what wire goes where, if you're not sure about how to install an item, you should get a qualified electrician.

Q : My house lights have gone out and I've found this little fuse blown in my fuse-box, I've already been to the supermarket / petrol station / corner shop and bought some 5 Amp fuses but they are too big and won't fit into the holder.

A : They've sold you a fuse for a plug top, you really need a BS1361 5A consumer unit fuse, which is a little bit smaller.
