How can we test the installation of ABS and PVC pipe and fiitings?
Following installation and allowing the appropriate drying times, the suggested method of testing is to fill the pipework (consisting of either ABS and PVC pipe and fiitings) with water ensuring that no air pockets remain, and carry out a hydrostatic pressure test up to 1.5 times the maximum working pressure or rated pressure of the ABS or PVC system. The plastic pipework is then left pressurised for a period not exceeding 1 hour.
