Frequently Asked Questions — Pipe Diagnostics
How do I identify defective polybutylene pipes in my home?
Polybutylene pipes are typically flexible, dull gray (sometimes blue or black) plastic lines stamped with code 'PB2110'. They were widely installed between 1978 and 1995 and are frequently visible at water heater connections, under sink cabinets, or near the main water meter.
What causes copper pinhole leaks in Denver Metro plumbing?
Copper pinhole leaks are primarily caused by excessive municipal water velocity, high line pressure (above 80 PSI), aggressive water chemistry, and mechanical friction along subterranean lines installed directly beneath concrete foundation slabs.
Can defective plumbing lines be replaced without tearing down all the walls?
Yes. Master Plumber Bill Clark specializes in minimally invasive repiping. By threading flexible Uponor PEX-A expansion piping through basement floor joists, drop ceilings, crawlspaces, and interior partition cavities, we replace whole-home supply systems with drywall openings in just 1 to 2 days.
