Reasons The Drain Valve On Your Water Heater May Need Repairs

Blog

If you happen to notice a puddle of water near your water heater, you may feel frustrated over the mess and worried your water heater is ruined. However, a leak from the water heater doesn't always mean the heater needs to be replaced. A water heater repair service can find the source of the leak and then make repairs if possible. A common cause of leaking from the bottom of your water heater is a bad drain valve. Here's what causes a leaky drain valve and how a repair service can help.

A Drain Valve Might Leak Due To Age Or Damage

If the valve on your water heater is made from plastic, the plastic might be old and worn out or cracked from being bumped. A valve usually has a rubber seal in it and the seal might be worn since rubber tends to wear out with age. Another problem could be sediment buildup that's keeping the valve from closing completely.

The first thing a water heater repair service does is verify the leak is coming from the valve. Water might be forming due to condensation or dripping down from a leak higher up the tank. The leak could even be coming from the tank itself if the tank is rusty.

A Leaky Drain Valve Is Repaired Or Replaced

If a plastic valve is worn down, the plumber will need to replace it. If the valve is brass and just has a bad seal, the plumber may just replace the seal. If the valve is clogged with sediment, the valve may need to be cleaned out so it functions properly.

Repairs start with draining the tank. A hose is attached to the valve so water can drain in a floor drain or outside. The valve is opened fully and the plumber waits for the tank to get empty. A side benefit of draining out the tank is that sediment buildup is flushed out with the water so your heater may work better and there won't be sediment to block the new valve.

When the plumber starts work on your water heater, they verify the power and water supply are off. Then, the old valve is unscrewed from the side of the tank. If the plumber is just replacing the seal, a new seal is put in and the old valve replaced. If a new valve is being put in too, the plumber replaces both the seal and valve and applies plumbers tape on the threads so the valve screws in tight and water won't leak.

When the valve is in place, the water is restored, and the work is checked to make sure nothing is leaking around the valve. Changing a drain valve is a fairly easy water heater repair job, but it does have some safety hazards and challenges.

Working around hot water could be dangerous, and the valve may be stuck and refuse to budge. However, a plumber can overcome these problems and get the valve repaired so the leak stops and the threat of water damage is eliminated.
