I am just in the process of refitting bathroom and toilet. I will be
tiling the walls and probably the floors (may use vinyl though).

To simplify things I am considering using plastic pluming to plumb in a
radiator/towel rail. Has anyone any idea on the reliability of using
these fittings. I am happy soldering, but moving the pipes around is a
lot harder, hence the thought of using plastic.

Obviously the last thing I want happening is for a joint to fail behind
a tiled partition or under a floor.

Thanks

Tim
