Pressure Test Leakage
Pressure Test Leakage
(OP)
We are having problems with our ductile iron line/ HDPE line holding pressure.
The contractor says its an air lock problem, and we said its a water leaking somewhere.
We pressurized the waterline up to 125psi and 70 minutes later it dropped to 95psi.
Is there a way to know if this is a water leak or if it is an air lock issue.
Please advise.
Thanks

If there is a leak, then you know it is not an air lock problem.

Hope this helps.

I'm not familiar with HDPE pipe, but with ductile iron I've seen the type of pressure loss you describe even though the leakage was barely measurable.

Honestly, a good contractor wouldn't have a problem with their line.
