Why Is My Water Heater Leaking?

When your water heater leaks, it can cause serious problems in your home. A leaky water heater may throw a wrench into your routine, cause permanent damage to your possessions, harm your water supply, and raise your energy bill. Should you suspect a leak, you need to take the necessary measures to determine the cause and fix the problem.

Today, we are going to explore the most common reasons for water heater leaks, as well as solutions to resolve the issue and prevent further losses.

How To Identify a Water Heater Leak?

A puddle of water around the unit is usually the initial indication of a leaky water heater. Nevertheless, the leak may not necessarily be noticeable. At times, you may see some drops of water. Here’s what you can do to determine if you have a leaking water heater at your place:

• Test water pooling: If a puddle forms around your water heater, this may indicate a leak.
• Find the origin: When there is little water on the heater, check it now and then after every few hours and see whether the water has evaporated. If the area is wet, then there may be a water heater leak.

Common Causes of Water Heater Leaks

Your water heater may leak due to several problems. The most prevalent culprits are as follows.

1. Leaky Drain Valve

Your water heater has a drain valve at the bottom that drains the tank during maintenance. With age, this valve may become loose or corroded, allowing water to leak. Thirdly, if you see water dripping from the drain valve, it may be necessary to tighten it. If that doesn’t fix the issue, you may need to replace the valve.

2. High Water Pressure

Overpressure in the water heater can be destructive, leading to spillage. The water heaters have a predetermined level of pressure (usually about 150 psi). If the pressure is excessive, it may make the tank or valves leak.

To check for high pressure:

• The tank will have a pressure relief valve that releases water when the pressure exceeds a set limit.
• If the valve does not function or is releasing excessive water, the valve might require replacement.

3. Age of the Water Heater

The older water heaters are prone to plumbing leaks. The average lifespan of most water heaters is 8-13 years, depending on maintenance. The old units are more likely to experience internal corrosion, cracks, or weak tank walls. If your water heater is due and leaking, it may be time to replace it.

What Do Leaks from Different Areas Mean?

Leaks can occur from various parts of the water heater, and the source can help you diagnose the problem.

1. Leaks from the Top

The top of the water heater tends to leak when there is a problem with the cold-water inlet valve or the hot water outlet. These leaks must be addressed by water heater repair experts immediately; if neglected, they may spread, damaging more of your water heater.

2. Leaks from the Bottom

A defective drain valve or corrosion at the base of the tank typically causes leaks at the bottom of the water heater. When the leak is caused by the drain valve, it is usually possible to fix the problem by tightening the drain valve. However, when the tank itself is leaking, it may require replacement because of age or internal damage.

3. Leaks from the Side

The temperature and pressure (T&P) relief valve is typically associated with leaks on the water heater’s side. This is a safety feature that releases hot water and steam if the pressure or temperature in the tank becomes excessive. The valve might need to be replaced if it is not functioning correctly. Consider checking the temperature on your water heater before you do this, because an incorrectly set water heater may cause the valve to open too soon.

Steps to Take if Your Water Heater is Leaking

In case you find your water heater leaking, the following are the steps you can take at the moment in order to reduce the damage and avoid complications.

1. Turn Off the Water Supply

The first thing you will do is to turn off the water supply to the heater. This will help prevent any additional water leakage and damage to your floor or walls.

2. Shut Off the Power Supply

For electric water heaters, turn off the power at the circuit breaker. If you have a gas-powered water heater, turn off the gas supply to avoid potential safety hazards.

3. Identify the Source of the Leak

After cutting off the water supply and power, ensure you find the source of the water. If the leakage is through the drain valve or T and P valve, sealing or replacing these components may suffice. But if the tank is leaking, it may be time to replace the unit.

4. Contact a Professional

If you’re unable to pinpoint the source of the leak or if the leak is severe, it’s best to contact a licensed plumber or water heater repair service in San Marcos, TX. They can inspect the unit, diagnose the problem, and recommend the appropriate solution.

Preventing Future Water Heater Leaks

The frequency of maintenance is fundamental to preventing water heater leaks. The following are a few things that you can do to decrease the unusual water heater noises and increase the lifespan of your unit:

• Schedule regular maintenance: Have your water heater inspected by a professional plumber every year.
• Check the pressure regularly: Make sure the pressure relief valve is functioning correctly.
• Flush the tank: Sediment can accumulate over time, which damages the tank. Regular flushing of the tank will keep it in good working condition.
• Inspect the valves: Ensure that the drain valve and T&P valve are functioning correctly.
