Hydrotesting

Northern hemisphere, or southern?

It's in the Phils. Sorry I don't know which hemisphere we belong. My problem is the owner tested the waterline I construct inside the house on 100 psi pressure in 15 minutes. All the fittings broke up and leaks by droplets were visible. By engineering standard and practices, it should only be tested at 60 psi max pressure. Can I claim for damages

My point was that if you supply no useful information, you will receive no useful help.

I am not a lawyer, nor a civil engineer. This can only be settled locally. A forum will provide you no recourse.

What was the material and thickness of pipe?.

1/2" diameter plastic pipe called it here as ESLON BLUE sealed by pvc solvent

What is it rated at, i.e. its maximum operating pressure at local ambient temperatures?

What type of water service pipe & fittings did you install? Was it copper pipe? If so, what copper pipe type, Type L or M (in the USA), and if not those types, what are the specs for the pipe? Were the pipes & fittings soldered (sweated)?

If not copper pipe & fittings, what exactly did you install, and to what specification (grade, etc)?

100psi test pressure isn't uncommon, and if copper pipe & fittings that have been properly sweated it should have hold that pressure for a lifetime.

What is the residual water pressure on the service line entering the house, if on public system....or for that matter if on a private well?
