How to Deal With a Leaking Water Heater in Dallas, TX

Is your water heater leaking all over your floor? That situation might not affect its performance, but leaks are a serious problem that should always be solved immediately. Leaking water that isn't stopped will eventually cause serious water damage to your property.

Water heater leaks are a common problem in Dallas. Minerals and sediment buildup in the city's hard water increase wear on all plumbing fixtures, and the effects are most severe on the systems that people use every day. Every plumbing system has a limited lifespan that's only made shorter by the effects of daily use. Most heater units in Dallas start having frequent failures around the ten-year mark.

Leaking is a common sign of deterioration. There are several components that will all cause that problem if they're not regularly inspected for issues and replaced when necessary. You should always take advantage of routine maintenance services provided by your local, reliable plumbing company to avoid surprising issues and catastrophic failure.

Mr. Rooter Plumbing of Dallas is here to help with all leaking water heaters! Our team of professionals supports Dallas with guidance about how to identify leakage and what to do when you find it — plus, exceptional repairs and replacement services. Just a few simple steps will help you avoid the effects of water damage and other issues.

How Do You Know if Your Water Heater is Leaking?

Did you know that condensation can appear on a normal water heater? When cold water enters a tank, it will create condensation if air around the unit is warm, just like what you might see on a refreshing, cool beverage during a hot summer day. That's not an issue you should worry about — unless that moisture doesn't go away.

If you notice any warning signs that you need heater repairs, you can get prompt solutions or replacement service. For leakage, a visual inspection is usually sufficient.

Warning Signs Include:

  • Rushing sounds or dripping noises

  • Puddles on top of the unit or near the bottom

  • Liquid running down unit exteriors

  • And, unusually high utility bills

What Should You Do If You Have a Leaking Water Heater?

Responding quickly to any plumbing issue is essential for avoiding serious situations down the line. If an issue isn't affecting performance, many people in Dallas will choose to ignore it, but leaks that go unaddressed will only get worse over time. Even if your shower stays hot, you should still take immediate action to address leakage.

1. Close Your Cold Water Supply Valve

This step is particularly vital if you have an issue with a conventional tank model, but it's an important step for addressing issues with tankless water heaters too. Most models have a dedicated shut-off valve on their inlet pipe.

Most intake pipes are connected to the top of units. Your valve will either be a wheel that you need to turn or a handle. If it's missing or broken, you can also turn off the water to your entire home at your main shut-off.

2. Turn Off the Power Supply

For electric heaters, you simply need to locate your circuit box and flip the appropriate breaker. For gas heaters, you need to shut the gas supply valve located on the intake line leading to your tank. It's typically located near the bottom of a tank.

3. Locate the Leak

This is easier said than done, as there are several areas you should inspect and you may not be able to pinpoint its location. Generally speaking, most components cause problems either at the top or base of the units, so those are the places you need to focus on. Leaks at the top can often be fixed. Leaks at the bottom often mean you'll need to consider replacement options.

At the Top

First check your supply valve for any problems. Loose connections are a common cause of water heater leakage, and they can be fixed. If your supply valve is working fine, move on to your next valve.

Your pressure relief valve (T&P valve) is a safety feature designed to release water when pressure inside your unit gets too high. It is usually located on the side or top of a unit. It has a small handle that flips up, with markings that indicate your unit's current PSI (pounds per square inch).

When pressure in your unit gets too high, your T&P valve will release fluid to reduce stress on your system and prevent disasters. If that's happening, you'll need to address those pressure issues. A T&P valve can also fail, which will result in unnecessary leakage.

At the Bottom

Check your drain valve first. Confirm that it's completely closed. If anything is dripping out, you might need to replace a worn washer. If a drain valve is leaking where it connects to your tank, that's a sign of internal leaking.

Leaking tanks often create puddles under units or issues with valve connections. If you see puddles, double-check to confirm that an issue at the top isn't running down the sides and pooling below.

When an issue is located at the bottom, or you can't find the location of a problem, you should consider calling a professional plumber or service technician to diagnose your issue and fix it. Water heater replacement is often your only option for a leaking tank.

4. Call A Plumber

Although it's possible to handle some repairs yourself, only a plumber will provide exceptional, lasting repairs and professional insight for your needs. A skilled plumber is your best option for determining whether you need repairs or replacement — and their skills will be essential for installation.
