Hi all.
A friend is doing his bathroom and wants to run the wash basin cold and hot water pipes and discharge pipe into the solid wall, plaster over and out into the existing hopper before tiling the wall.My questions are
1) when you run the h&c water copper pipes from the tap and straight into the wall, do you then pull manual bends wherever needed or are there points in the wall where it is better to use end feed elbow fittings?
2) are you allowed to use end feed fittings at all or is it advisable not to use fittings?
3) do you cover the pipes with insulation tape or is it better to use a 20 mm. plastic pipe to protect the copper pipes and to allow for linear expansion?
4) if you use plastic pipes to protect the copper, how do you prevent the plaster from running into the plastc pipes when you plaster over?
5) copper pipes sweat, so will they cause any damage to the wall over time?
6)when you run the discharge pipe into the wall, do you go then straight down the wall then give it a gentle fall and out into the hopper or into the wall, then gentle fall first then straight down before going out into the hopper or it does not matter either way?
Thank you very much for your time.
