should water pipes be underground

[maffie]

I am having a shower and toilet room being built downstairs could you please advise me whether the water pipes and central heating pipes should be above the concrete floor or under, I am getting confused

Better to be above ground IMHO.

Any leaks will be apparent and you will have access to the joints for a repair.

thanks 4r ur reply I will now insist on the pipes being out of the concrete

You could form a duct in the concrete which makes things much neater!!
Poly pipe do a range of ducts and fittings!
