This is a water heater connection we inspected in an older Portland-area home this week.
That green buildup you see is active corrosion at the water heater fitting. When fittings start oxidizing like this, it’s only a matter of time before they begin leaking.
Corroded water heater fittings are one of the most common causes of unexpected water damage in basements, garages, and utility closets.
If your water heater is 8–15+ years old and you’re seeing corrosion at the top fittings, flex lines, or shutoff valve, it may be time to address it before it becomes an emergency.
We provide water heater inspections, fitting replacements, supply line upgrades, and full water heater replacement throughout Portland, Milwaukie, Clackamas, and surrounding areas.
Free estimates available.
