Water Heater Leak Repair Services in Portland
We do not sell expensive new water heaters or perform general plumbing remodels. We specialize 100% in diagnosing and stopping water heater leaks on residential and light commercial water heaters across Portland.
T&P Relief Valve Repair & Rebuild
When the temperature and pressure safety relief valve weeps, drips, or releases a steady stream, it compromises home safety. We test thermal expansion, inspect static water pressure, and install brand-new ASME-rated relief valves with code-compliant discharge piping.
Drain Valve Brass Upgrades
Factory plastic drain valves easily crack and weep around the threads. We safely drain sediment, extract worn plastic valves without damaging tank threads, and install full-port heavy cast-brass ball valves that will never snap or leak.
Supply Line & Dielectric Sealing
Leaking top connections ruin insulation and rust out top tank jackets. We remove corroded galvanized nipples, install lead-free dielectric unions to prevent galvanic reactions, and fit commercial-grade braided stainless steel flex connectors.
Tank Seam & Acoustic Diagnostics
Unsure if water on the floor is a loose valve or a burst internal tank? We conduct acoustic ultrasonic testing and thermal imaging to trace water tracks behind the jacket, providing definitive, honest answers on whether repair is viable.
Thermal Expansion Tank Leak Repair
A waterlogged expansion tank causes pressure spikes that blow out water heater seals. We check bladder charge, replace corroded mounting tees, and re-calibrate the expansion chamber to protect your water heater against Portland municipal surges.
Heating Element Gasket Resealing
On electric water heaters, hardened rubber element gaskets can leak water into the thermostat controls, causing short circuits. We isolate the electrical circuit, drain the tank safely, clean flange faces, and install high-temp EPDM O-ring seals.
