Common Pipes & Fittings Problems

Pinhole Leaks in Copper

Tiny holes from the inside out due to pitting corrosion. Start as small drips or green stains. One is a repair. Multiple are a warning that the entire system may be deteriorating.

Water Hammer

Loud banging when a valve closes suddenly. Shockwave can damage pipes, loosen fittings, and stress connections. Fix: hammer arrestors, recharge air chambers, or reduce pressure.

Frozen Pipes

Water freezing inside a pipe generates over 2,000 PSI -- enough to split copper, PEX, or PVC. Pipes in exterior walls, crawl spaces, attics, and garages are most vulnerable. Quick thawing before a burst saves thousands.
