Am looking to buy new shower tray. It comes with ones of these wastes. It has 90mm diameter connected to 40 mm pipe. I wanted to make sure when I install it it meets the building regs. I looked in Table 1 in section 1 page 7 of document H1 Building regulations 2000 (2002 edition). It seems to...

Yes definitely the connections. It isn't touching a joist, most of the pipe and connections are just suspended mid air at the point of creaking.

My central heating system uses speedfit pipes. When the heating is on, there is an intermittent creaking/ticking noise from the pipes. I have narrowed it down to a couple of connections - a 28mm elbow and a straight connector. What exactly would make these creak? Should I replace the whole...

In my upstairs bathroom and ensuite, I want to ultimately supply water to a bath, 2 showers, 2 washbasins and 2 WCs. Does it matter where I tap into the pipes to feed each thing? Do I have to always feed off the main pipe and run directly to each thing or can I feed off a pipe which is already...

I'm a newbie at all this and it seems a bit double dutch to me. Is there an explanation in laymans terms? I've never heard of equipotential bonding. I had a quick look in the bathroom. There seems to be no other earths connected to anything metal. The water pipes are plastic, but obviously the...

Just bought a whirlpool bath and am installing it myself. From the pump there is a cable (live, neutral and earth) which I have run through a hole in the connecting wall to a rcd protected socket in the adjacent bedroom, so no problems there but also on the pump there is an earth lead. Where...

thanks, that helps. Just one more question - probably a silly one, but I went to buy a waste pipe from a plumbers merchant and he asked me which colour I wanted. I said I dont mind but wondered why it mattered if they all get concealed. Or do different colours mean different things?

erm, thanks. which bit is the stub stack then? the section above floor level?

Been moving some stuff around in my bathroom which necessitates changing some of the drainage pipes etc and I've been reading up on the building regs to make sure I comply. Am still trying to get used to all the trade terminology as I'm a novice at all this. One thing I keep reading about is a...

No it has a valve thingy on the top, in white polystrene.

Thanks. So just to make sure I understood. In the old switch, I will end up with 3 red and a blue in L2, one red in common, and 2 yellows and a red in L1?

I have 2 doors entering my bathroom. I have a light switch outside one of the doors which turns all the lights on and off in the bathroom. I want to add a switch outside the other door, so I can use either switch to turn the lights on or off. I have a new 2 way switch and have connected the...

My main discharge stack in my bathroom is a couple of feet away from the wall and there is a 110mm vent stack going straight up into the loft. Because of this, quite a large part of the corner of the room is boarded up. I would like to create a bit more space and put a shelf in and wondered if i...
