That small plastic spigot at the bottom of your water heater is the drain valve — and it's one of the most failure-prone parts on the whole unit. Factory plastic valves crack, clog with sediment, and start weeping right when you need them most: during a flush. Water Heater Leak Repair Company replaces them with full-port brass ball valves that drain faster, seal reliably, and make future maintenance dramatically easier.
A quality drain valve isn't just a leak fix — it's a longevity upgrade. Annual flushing is the single highest-value maintenance task for a tank heater, and a clogged plastic valve is the reason most homeowners skip it. With a brass full-port valve installed, your yearly flush takes minutes instead of an afternoon of frustration, and your tank stays sediment-free for years longer.
We determine whether the valve is weeping from the stem, the threads, or a cracked body — and check sediment load behind it.
We safely drain the tank to below the valve level, capturing sediment so you can see what was inside.
A full-port brass ball valve goes in with fresh thread sealant — a permanent upgrade over the factory plastic.
We flush the tank through the new valve, verify flow, and pressure-test the seal.

Sometimes a loose packing nut just needs a quarter-turn. But cracked plastic bodies and sediment-fouled seats won't seal reliably — replacement is the lasting fix.
It has a straight-through bore the same diameter as the pipe, so sediment flows out instead of clogging. Brass won't crack or deform like the factory plastic valves.
It enables the fix: with a working valve you can actually flush the tank. We'll flush thoroughly during the visit and show you how to do the annual maintenance flush yourself.
Usually under two hours including drain-down, installation, flush, and testing. Most visits are completed in a single appointment.
Yes. We have techniques to clear or work around a clogged valve safely. In rare severe cases we drain through the T&P port — always with proper precautions.
