No. According to AWWA M23: PVC Pipe - Design and Installation Manual of Water Supply Practices,
there is a zero leakage allowance. There is a make-up water allowance designated during acceptance
testing of PVC pipe, as detailed in AWWA M23; however, that is NOT to be misinterpreted as
“allowable leakage” of in-service PVC pipe.
The make-up water allowance during testing is in place to allow for the following:
- Make-up for entrapped air
- Make-up for movement due to seating of valves, joint restraints, etc.
- Make-up for slight increase in pipe diameter due to internal pressures
Refer to Uni-Bell’s Technical Brief for more details on AWWA’s stance on zero leakage in PVC pipe here.
