Common causes of hot water heater leaks

A water heater leaking can be a big problem. If you’re not sure what’s causing the leak, it’s important to have a professional inspect the unit.

However, there are 15 common causes of leaks that you can check for yourself.

1. Temperature and pressure relief valve:

This valve is a safety feature that helps release excess pressure and heat from the water heater. A leaking valve can be caused by a faulty or broken valve, or simply because the valve is old and needs to be replaced.

2. Loose connections:

Over time, the fittings and valves in a water heater can become loose, which can cause leaks. Make sure all of the connections in your water heater are tight and free of any corrosion.

3. Corroded pipes:

If the pipes leading to and from your water heater are corroded, they may start to leak. Check the pipes for any rust or damage and have them replaced if necessary.

4. Cracks in the tank:

As water heaters age, the tanks can develop cracks. These cracks can be caused by many things, including over-pressurization, corrosion, or simply old age. If you see any cracks in your water heater, it’s important to have a professional inspect it as soon as possible.

5. Leaking around the base of the unit:

If you see water leaking around the base of your water heater, it could be due to a cracked base or a loose drain valve. Check the base for any cracks or damage, and make sure the drain valve is tight and not leaking.

6. Overheating:

If your water heater is overheating, it can cause the tank to crack and start leaking. If you think your water heater is overheating, turn it off immediately and call a professional for help.

7. Not enough cold water:

If there’s not enough cold water going into the water heater, it can cause the unit to overheat and leak. Make sure the cold water supply valve is open all the way and that there’s no blockage in the pipes leading to the unit.

8. Too much hot water:

If you’re using too much hot water, it can cause the unit to overheat and leak. Try to use less hot water and see if the problem goes away. If not, call a professional for help.

9. Sediment build-up:

Sediment can build up in the bottom of the tank over time and cause leaks. To remove sediment, drain the tank and flush it with clean water. You may need to do this several times a year to keep your water heater working properly.

10. Thermostat problems:

If the thermostat is set too high, it can cause the unit to overheat and leak. Try turning the thermostat down and see if the problem goes away. If not, call a professional for help.

11. Anode rod problems:

The anode rod helps protect the water heater from corrosion. If the anode rod is corroded or damaged, it can cause the unit to leak. Try replacing the anode rod and see if that fixes the problem. If not, call a professional for help.

12. Drainage problems:

If the drain valve or pipe is blocked, it can cause water to back up into the tank and start leaking. Make sure the drain valve is open and the pipe is clear of any obstruction. If that doesn’t fix the problem, call a professional for help.

13. Inlet water pressure:

If the water pressure going into the unit is too high, it can cause the tank to leak. Check the water pressure and have it adjusted if necessary.

14. Outlet water pressure:

If the water pressure coming out of the unit is too high, it can cause leaks in the pipes or fittings. Check the water pressure and have it adjusted if necessary.

15. Improper installation:

If the unit was not install properly, it can cause all sorts of problems, including leaks. Make sure the unit is installed according to the manufacturer’s instructions. If not, call a professional for help.

Conclusion:

These are just some of the most common causes of water heater leaks. If you’re having trouble finding the source of the leak, or if you can’t fix it yourself, call a professional for help.
