There are many things that could go wrong with your water heater. One of such complications is a leakage. You should have your unit inspected by a professional to remedy the problem. This article will focus on the common causes of a water heater leak. It’s important to know what’s causing the leakage. You will be to take actions on how to prevent a water heater leak from happening if you know its causes.
1. Connections and joints of the heating system are corroded or damaged
It’s evident that a water heater has leaks when puddles of mud are near it; but it can be more difficult to identify leaks if it’s happening on the connection and joints. One of the most prominent causes of a leakage is from a corroded or damaged connection/joint. The reason why it’s difficult to fix a leak from a piping connection is that the leak isn’t noticeable. A few droplets from the piping connection can evaporate — making it impossible to find evidence. Unless of course there is a pipe break and gallons of water are flowing out of the pipes. The only way to avoid this problem is through a maintenance inspection.
2. Broken drain valves
This valve helps drain your water heater if you decide to flush it out for maintenance. If you turned it off and it’s leaking then it’s most likely that the drain valve is simply damaged. Another possibility would be sediment accumulation on the valve. This may cause the valve to partially open. Check the washer if it has any cracks or signs of damage. The washer is part of the valve and is either made of plastic or rubber rings. Replace the washer or valve if it’s broken.
3. The temperature and pressure relief valve is dysfunctional
This valve releases water in case the water heater undergoes high pressure and temperature. The leak could be from this valve if it’s dysfunctional. The T&P valve may be malfunctioning. It could be detecting the pressure or temperature is high even though it’s not. Have a plumber check the valve if it releases water even the tank isn’t hot or under high pressure.
4. The water heater is just old
Water heaters are built to be used for many years but will eventually age and die out. An old unit that’s near its lifetime is more prone to complications — especially leakage. Some rusting components may break and cause water to come out of it. You must replace the old water heater with a new unit. You’ll be just wasting money on repairs on an old system.
5. Sediments on the bottom of the tank
Sediments accumulate due to the mineral content of the water supply. These sediments harden and stay on the bottom of the tank. The heating unit will also heat the sediments. These heated sediments can cause pressure and temperature increase to the bottom section. The metals of the lower section of the tank will expand due to the sediment. It will continue to expand until the metal burst and cause leaks.
