Hot water heater leaking is not a rare problem, especially if your water heater is not new. However, not always a leaking hot water heater suggests that you replace it for a new one right away. Leaks may be caused by minor problems, occurred to different parts of a water heater. Replacing them can extend the life of your current water heater and save your budget.
Hot Water Heater Leaking: Causes & Solutions
If one day you find some water, collected under your water heater, you ll believe it s leakage from the heater. It probably is, however, there are other reasons as well. When the source of leakage is obvious, it s easier to determine what has gone wrong. Otherwise, you should also rule out the following:
#1. Drainage problem when water is coming from the outside to that part of the house, where the water heater is located.
#2. Condensation. Water could have condensed at the bottom of water heater, especially if there are some openings there.
With these ruled out, examine your water heater carefully to determine where exactly water is leaking from.
Hot Water Heater Leaking From Top
#3. Water flex lines from above. This is one of the most frequent causes of hot water heater leaking from top. If flex lines go bad, water heater leaks from top.
How To Fix?
Shut water off, remove insulation around the flex lines, and inspect the flex lines for damages. If the flex lines need replacement, do that to fix the leakage problem.
#4. Temperature and pressure valve. If your water heater is overheating, it may increase a buildup of pressure as well. This problem may be caused by improper work of the house pressure regulator.
How To Fix?
Check if the house pressure regulator is working normally. If it s OK and the temperature and pressure valve are the culprit of leakage, you will have to replace it. This one is a more complicated repair than replacement of flex lines, so it may be better to trust this work to a professional plumber. If you still opt for that yourself, make sure that both hot water and pressure are off the line before you start.
Hot Water Heater Leaking From Bottom
#5. Drain valve. Hot water heater leaking from bottom often happens due to old drain valve because it fails to shut off completely after water draining.
How To Fix?
The problem can be fixed temporarily if you cap the drain valve using a hose cap. The better solution is to replace the drain valve. Before you begin working on the repair, shut off hot water and drain the water heater down.
Note that when it s not easy to determine the source of leakage, you need to remove access panels to the temperature setting.
When Leaking Hot Water Heater Still Has to Be Replaced?
The leaking tank of a water heater is a major problem why you have to replace the whole water heater, as this type of leak is not repairable. If you have previously checked your water heater for other possible causes of leakage and fixed what necessary, it s likely that you are dealing with a leaking tank.
