There are several indicators when your water heater needs to be replaced. Taking a few minutes to analyze your water heater performance can help you determine if it is time for a replacement. Being proactive now can help eliminate inconvenience or unforeseen damage if your tank should suddenly go out.

Different Types of Water Heaters


Natural gas water heaters are the most common water heater in the North DFW area by-far. Most of these have a rated capacity of 50 gallons. New gas tank-style water heaters have many more safety features than those of the past – the biggest of which is a closed-combustion design. Gas water heaters are efficient and very reliable over the long-haul.


50 gallon electric tank-style water heaters are also very common. Typically, these are installed in neighborhoods that do not supply gas hookups. These will usually last between 13-15 years before the tank itself starts to leak. It is not uncommon for one of the heating elements or thermostats to fail before that though. This can be changed out without replacing the entire tank.


Tankless technology has been around for a long time, but it is only recently really taking off in the Collin/Denton County area. Many new homes are being built with a natural gas tankless water heater pre-installed. Many of these are installed in the exterior wall, some are installed in the garage, and some are installed in the attic.

Legacy Automatic Advantage

When we install your new Rheem water heater, we will upgrade your water heater installation with:

  • New Stainless Steel Water Supply Lines
  • New Quarter Turn Water Shut Off Ball Valve

PLUS: We pull a permit and check the specific code requirements of the city you are located in to make sure everything is done up to code and passes inspection the first time. We dispose of the old, damaged heater at no extra cost.

What if I don’t need a new tank?

Age and lack of hot water are not always indicators of needing replacement. You may just need a repair. We want to provide you with an honest diagnosis and course of action for your water heater that fits your budget and needs. We will NEVER sell you anything you do not need.


A gas water heater is expected to last 10-12 years, while an electric model tends to last 10-15 years. If your heater is getting close to its life expectancy, especially if located indoors or in an attic, it may be prudent to change it before it goes out or starts leaking.

Discolored Water

Do you get tinted water when you open up the hot water tap? Rust-colored hot water is an indication of a bad tank.

Inadequate Temperature

If your hot water is not as hot or if you run out of hot water under normal conditions, it may be time for a new water heater.



Moisture around the base may signal a slow leak. If the water is pooling around the bottom with no sign of water on the supply lines, then the tank itself if probably leaking.

Water Heaters
Unfortunately, we purchased a house with a lot of issues, one being that we needed 2 hot water heaters replaced within the first year. After having a few negative experiences with other local plumbing companies I finally found Legacy by reading reviews. Besides having sincere positive reviews; I was impressed with their monthly missions giving back to the community. It has been a very positive experience from the start with Meagan and ending with Brandon and Jose installing my new hot water heaters last Friday. For the first time in 9 months, I have had a full hot shower! Not only did Brandon and Jose explain everything they were doing; they also answered all of my questions. You may pay a little more, but you get what you pay for. I have a few other plumbing issues that need to be addressed, and you can be assured that Legacy Plumbing will be my first phone call.
Water Heaters
They installed a hot water heater. They showed up on time and were very professional. They knew what they were doing and finished in less time than I expected. They were upfront on the price and explained everything they would be doing. The plumber's name was Sean and I can't remember his assistants' name but they were very nice and I would call them again when a plumbing need arises.

Luis and Steven replaced two water heaters. They were professional throughout the process. Helpful and informative. We would request them again if we need plumbing work in the future.
