Why Your Water Heater is Leaking

Fast Water Heater Repairs in Philadelphia & the Surrounding Areas

Finding out that your water heater has a leak is never a pleasant experience – but if you know what causes these leaks, it’s easier to stay calm and address the problem efficiently.

At Reliable Plumbing & Drain Cleaning, we’ve seen our fair share of water heater issues and are here to shed light on the common causes of leaks and what you can do about them.

Age and Corrosion

Water heaters typically have a lifespan of 8 to 12 years. As they age, corrosion can set in, particularly if the anode rod, which is designed to prevent such corrosion, is depleted and not replaced.

The tank itself may start to rust, leading to small fractures or holes that can cause leaks. If your water heater is old and showing signs of rust, it may be time to consider a replacement.

High Water Pressure

Water heaters are designed to operate within a certain pressure range, usually around 60 to 80 psi. If the water pressure in your home exceeds this range, it can stress the water heater and associated plumbing, potentially causing leaks.

Installing a pressure-reducing valve or checking the pressure regularly with a gauge can help prevent issues related to high water pressure.

Faulty Temperature and Pressure Relief Valve (T&P Valve)

The T&P valve is a critical safety feature on your water heater that releases water if either the temperature or pressure inside the tank gets too high.

If this valve is malfunctioning or stuck, it could either leak or, worse, lead to a dangerous increase in tank pressure.

Testing this valve annually and replacing it if it shows any signs of malfunction is an essential maintenance task.

Loose Connections

Leaks can also occur at the water inlet and outlet connections. These should be among the first spots you check if you notice a leak.

Sometimes, fixing the issue can be as simple as tightening a connection with a wrench. However, if the fittings are corroded, they may need to be replaced.

Internal Tank Leaks

If the leak appears to be coming from the base of the tank, this could indicate an internal problem, such as a crack or hole in the tank itself, often due to sediment buildup over time which leads to overheating and tank damage.

Unfortunately, an internal tank leak usually means the water heater needs to be replaced.

Condensation

Sometimes what appears to be a leak may actually be condensation. This can occur if there is a lot of moisture in the air or if the water entering the heater is very cold, causing moisture on the tank’s exterior to condense and drip off like a leak.

Check if the moisture appears during times of high usage and disappears later, which indicates condensation rather than a true leak.

Solutions and Preventive Measures

• Regular Maintenance: Schedule annual inspections and maintenance to catch and address issues early.
• Anode Rod Replacement: Get the anode rod replaced every few years to prevent tank corrosion.
• Monitor Water Pressure: Get a pressure gauge installed, and a pressure-reducing valve if necessary.
• Inspect Regularly: Keep an eye on the condition of valves and connections to catch leaks early.
