Mayfair is Southstar's master-planned community on the north side of New Braunfels: roughly 2,000 acres, with about 6,000 homes planned. The City Council approved it in June 2021 and ground broke in April 2022, so every house here is still on its first water heater.
Where Mayfair sits, and who is building it
Mayfair straddles I-35 inside a rough box: Watson Lane to the north, Kohlenberg Road to the south, FM 1101 on the east, and FM 1102 and Hunter Road on the west. It lies in the city's extraterritorial jurisdiction (ETJ), outside the city limits.
Perry, Highland, Toll Brothers and Coventry are building, and D.R. Horton joins in 2026. Guthrie Trail, Vista Parkway, Cleveland Way and Tug Point are among the early streets, with Mayfair Elementary on site, 300-plus acres of parks and 35 miles of trails.
What does the first water heater in a new Mayfair house need?
Attention more than repairs. A new tank lasts longest when it is looked after from year one, and most owners never touch it until it fails.
- Drain it yearly. A.O. Smith (opens in a new tab) says at least once a year, more often on hard water.
- Check the anode rod by year 3. It corrodes so the steel tank doesn't.
- Keep the dial near 120°F. That's the temperature the U.S. Consumer Product Safety Commission (CPSC) recommends (opens in a new tab).
- Keep the label details. The model and serial decide what a manufacturer covers.
Where the tank sits matters too. Across Texas, new homes of this kind most often put it in the garage, with attics the other common spot. An attic or closet water heater needs a drain pan under it under the 2021 International Plumbing Code, which New Braunfels adopted in 2023.
Looking after it from the start is what stretches a tank toward the long end of a typical 8 to 15 years; how long water heaters last shows which habits matter most.
Hard water starts on the first fill
Scale doesn't wait for a house to age. If New Braunfels Utilities (NBU) supplies your water, its 2019 water quality report (2018 data) put hardness at 8.1 to 19.5 grains per gallon, averaging 15.1. NBU's newer reports publish no figure.
Because Mayfair is in the ETJ, check your water bill to see who supplies it. Whoever it is, a yearly drain keeps sediment off the bottom of the tank, and the guide to hard water and water heaters covers whether a softener is worth adding to a new build.

Will the builder's warranty cover a failed Mayfair water heater?
It may, so check the builder's paperwork before paying for anything. An installation fault inside the builder's workmanship period is normally theirs; a failed part may fall to the manufacturer.

Cost of a typical repair visit, near $550 on average
Common fixes on a young tank are a thermostat, a heating element on an electric tank, or a pilot part on a gas one. Check which fuel your home has before you call; CenterPoint gas reaches many parts of New Braunfels, but not all.
Does a water heater replacement in Mayfair need a permit?
Ask before any work starts, because Mayfair's ETJ status can change the answer. Inside New Braunfels, the City's permits page (opens in a new tab) lists replacing any plumbing system as permitted work. In the ETJ, ask which permit your address needs when you get your price. The licensed plumber doing the job normally pulls it, and the City's Building Division takes questions at (830) 221-4041. The New Braunfels permit guide explains what happens outside the city limits.
The quote should also name any code parts. The main one in new construction is an expansion tank, which the 2021 code requires wherever the cold line passes through a check valve, pressure-reducing valve or backflow preventer.

Questions homeowners ask
Who supplies the water to my Mayfair home?
Your water bill names the supplier, so check it, since Mayfair sits in the ETJ outside city limits. If it's NBU, the 2019 report put hardness at 8.1 to 19.5 grains per gallon, which makes a yearly drain worthwhile from the start.
Can I switch my new Mayfair home to a tankless water heater?
Usually, where the fuel and venting allow. A tankless water heater installed typically runs about $1,600 to $4,500, plus a few hundred dollars more when gas, venting or electrical work is needed, and the switch from a tank takes about 4 to 6 hours.
Does a water heater in a brand-new Mayfair home need any maintenance?
It does: drain it once a year from the start and have the anode rod checked by year 3. Scale builds from the very first fill, whichever builder installed the tank.
Can I get water heater help in every Mayfair builder's section?
Yes. Perry, Highland, Toll Brothers and Coventry homes are all covered, and D.R. Horton's will be as they arrive in 2026.
