Installing an outside tap

[Cono1]

Hi

I have to install an outside tap for my daughter. The rising main comes in at the front of the house, the tap is required for the rear garden.

The best option would be to tee off from the rising main to the upstairs boiler which is in an airing cupboard upstairs, the boiler is a Potterton HE condensing unit with an integral tank for the hot water supply. In the installation instructions there is provision for a tee off after the shut off valve for a shower so that the cold supply is of equal pressure. Would it be possible to use this or is it inadvisable? Where this facility has been made it does not appear to be a straightforward blanking off plug but appears to be a brass nut on a threaded spindle. The supply pipe to the integral water tank (which I think I can identify from the installation instructions) appears to be of 22mm steel, so it may be possible to tee off from this (would it be OK to use a copper tee with the steel?). Or should I just tee off the rising main at the front of the house, take a pipe up the wall and across the loft and down the other side? Or is there a better way?

Sorry if I have been longwinded but have tried to give as much relevant information as possible.

Regards
Cono

Is there no water at all at the rear of the house? If you can find a suitable location at the rear, use that. There's no reason to go messing around with any of the connections to your boiler, you can however tee off the main rising to it if this is the most convenient location.

You'll need an isolator and a double check valve to comply with water regs.

Hi Muggles

No there is no supply at all to the rear of the house, the only other supply is to the bathroom and boiler which are upstairs and located in the middle part of the house, the bathroom adjoins the airing cupboard where the boiler is located. I must admit that I myself have reservations at taking it from the boiler shower tee off, but then considered that if I locate the pipe carrying the water supply to the integral tank in the boiler that this may be a better option. As said previously this pipe appears to be metal as opposed to copper and I did not know if it is OK to use a copper tee here.

Cheers
