Hi all,
I'm due to fit an outside tap for a customer. First time I've done it. I know all the theory, but have a few puzzlements...
1. I'm planning to sleeve the 15mm pipe, with 22mm copper pipe (or maybe plastic overflow pipe, which is cheaper). What do you recommend I seal the pipes in with - silicon? Plumbers caulk? Anything else?
2. I'll try to limit the amount of pipe running on the outside wall. There'll be at the minimum an elbow coming out of the wall, connecting into the tap (on a backplate elbow). When should I put insulation on outside pipe? Would an exposed elbow be OK? And maybe, say, an inch of vertical pipe? Or would you cut out an inch thick piece of insulation and wrap it round?
3. Do you prefer the elbow coming out of the wall to run up or down to the tap?
4. Do you drill with a slight run through the wall? Doesn't this comprimise the joints, which should all be 90 degrees?
5. Do you all fit drain valves on the inside wall? I've read it is good practise. However, I've yet to see a tap with one fitted. I presume it would sit on the vertical pipe run indoors, above the iso valve and DC valve?
6. Is there a recommended ideal height for the outside tap? Or do you just plonk it on where it looks good?
Thanks everyone for your advice. (Can't believe an outdoor tap could generate so many questions).
