Note:
- UPVC and CPVC pipes are a non conductor of electricity and also non subject
galvanic of electrolytic attack.
Electrical equipments should not be earthen to UPVC and CPVC pipes.
UPVC and CPVC pipes should not be used for compressed air or gas.
UPVC and CPVC pipes are intended to use for water and approved chemicals
only.
