Leaking Pipes & Fittings

Leaks are often found in water distribution piping and drain piping. Even small leaks can lead to damage to finished areas and an increased risk of mold growth in unfinished spaces. Tapes and sealants are not proper solutions to these leaks.

Corroded Galvanized Steel

Galvanized steel piping still remains in many older Portland houses. This material was once durable and reliable, however it has a tendency to corrode at threaded fittings. This corrosion can lead to leaks and restrictions in water flow. Most remaining galvanized steel water piping is at the end of its life.

Drains Issues

Sink, shower and tub drains become restricted over time and can require clearing occasionally. Leaks from sink and tub drains are very common. Flexible, corrugated (accordion) drains are more likely to clog and are not recommended, and drains with S-traps should be corrected.

Excessive Water pressure

Residential water pressure should not exceed 80 PSI. Too much pressure can put strain on piping and appliances, cause leaking faucets, and waste water. When water pressure exceeds 80 PSI, a pressure regulator on the water main is recommended.

Hose Bib Issues

Hose bibs on older homes are often outdated, lacking anti-siphon devices and freeze-proof features. Upgrading these older hose bibs is recommended. Additionally, hose bibs, whether old or new, can leak.

Other issues

• Missing shutoffs at appliances

• Uninsulated piping in unconditioned areas

• Poorly supported piping

• Dissimilar metals in direct contact

• Failed wax rings at toilets
