Essential Plumber Requirements
Pipe Selection:
Insist on PN16 or PPR pipes for high-pressure or hot lines instead of weak, low-pressure PVC.
Joint Sealing:
Ensure high-quality Teflon tape or thread sealant is used on all threaded connections—never reliance on excess glue.
Overhead Tank Safety:
Must install a functioning float switch or mechanical valve to prevent tank overflow and structural damage.
Layout Mapping:
Require a clear piping layout before cutting into walls to prevent accidental damage to hidden conduit or wiring.
