Hi everyone,
I am having a new water main installed at my property tomorrow - 25mm blue pipe buried in a 750mm deep trench. The idea is to put builders sand at the bottom and just on top of the water pipe as bedding although the installer is somewhat reluctant to do this saying it isn't really necessary in clay ground, that the water companies never do it, and that they never do it when moleing as it is impossible. I want it doing properly since I am paying all this money and don't want a squashed pipe. Why not do the best job possible?
Anyway, this has given me an idea. I gave a load of 110mm, orange drain pipe lying around here that is surplus to requirements. Would it be worth laying this at the bottom of the trench and running the water pipe through it for really strong protection? It would end up with air rather than material around it inside the pipe which may reduce insulation from freezing, that is the only downside I can think of.
Thoughts?
