Reasons Behind Water Heater Leaks

Reasons Behind Water Heater Leaks

Leaks coming from your water heater are a red flag, and this is something you should address as soon as possible. They usually start small, but when left neglected, it won’t take long for them to cause flooding and damage to your property. That is why as soon as you detect leaks on your unit, you should contact an experienced plumber in Milan, MI from Dynamic Drains immediately. 

To help you determine why your water heater is leaking, we cover some of the common reasons behind this problem.

Loose Drain Valve

Water heaters have a drain valve located at the bottom to empty the tank, which is essential for regular clean-ups. If you see standing water where your tank sits, your drain valve may be loose and is causing the leak. You may try tightening the valve with a wrench, but be careful not to overdo it. It’s also best to enlist professional water heater services if you’re unsure how to fix it.

Old Tank

If you own a tank-style water heater older than 15 years, you may experience recurring leaks. This is because as your unit ages, its components wear out, and corrosion starts to take its toll. Cracks will eventually form, causing leaks. If your old water heater is already past its prime, it would be wise to replace it with a tankless water heater. It’s more energy-efficient, space-saving, and has a longer life span.


Sometimes, what seems like a leak is caused by condensation that pools around your water heater. This usually happens because of cold water supply lines or when the temperature in the room highly varies from the tank. While condensation doesn’t indicate a serious problem the way a leak does, excessive condensation may cause your water heater to wear down prematurely. If you find your unit sweating frequently, seek an expert in water heater repair in Milan, MI to have a look at it.

Faulty Temperature and Pressure Relief Valves

These valves are responsible for regulating the temperature and pressure inside your water heater tank. When they become loose or damaged, they can cause water leaks from the sides of the tank. Once you notice this issue, reach out to Dynamic Drains immediately. Too much pressure may cause your unit to burst and warrant an untimely water heater replacement.
