Northwest Crossing Drive, Crosspoint Drive, Northgap Drive, Palo Crest and Northlake Drive were all built out between 2004 and 2010, northeast of Gruene and southeast of Country Hills. If your house still has its first water heater, that tank has outlived the usual range, and swapping it out before it leaks is the calmer way to do it.

Every house here is about the same age

The subdivision went up over roughly six years, so its water heaters did too. One listing on Northwest Crossing Drive shows a home built in 2005, and houses range from 1,250 to 3,660 square feet, with an homeowners association (HOA) and a sports court.

When a whole street is built at once, the tanks tend to wear out close together. If a neighbor has just replaced theirs, yours is likely on the same clock.

Is it time to replace the original tank in your Northwest Crossing home?

Yes, if it is the original. Every house here is older than the typical tank lifespan. Watch for these signs:

• Rusty hot water: the inside of the tank is corroding.
• Water in the pan or on the floor: a slow leak rarely stays slow.
• Popping or rumbling: sediment has built up on the bottom.
• Showers running short: the tank no longer holds its heat.

Hard water speeds all of this along. NBU's 2019 water quality report (opens in a new tab) (2018 data) gave a range of 8.1 to 19.5 grains per gallon, average 15.1, and its later reports print no figure.

Is your water heater in the garage or the attic?

Most likely the garage, but check before you call. In Texas generally, homes built over the last 30 years keep the water heater in the garage, though attic installs have been common for about 50 years. A garage tank that leaks makes a puddle; an attic tank that leaks comes through the ceiling.

That is why the 2021 plumbing code calls for a drain pan wherever a leak would cause damage. If yours is overhead, mention it when you call. If water is already coming through, the leaking water heater steps cover shutting off the supply and finding the source first.

What a replacement includes under the 2021 code

New Braunfels adopted the 2021 International Plumbing Code (opens in a new tab) in 2023, and a permit is required for a water heater replacement inside city limits. A complete replacement quote should list:

• The permit: normally pulled by the licensed plumber doing the job.
• Expansion tank: required when the cold supply passes a check valve, pressure-reducing valve or backflow preventer.
• Drain pan: required wherever a leak would damage the house.
• Relief-valve line: runs by gravity to within 6 inches of the floor or pan.
• Haul-away: the old tank leaves with the job.

The water heater permit guide for New Braunfels explains who normally pulls it and what the City checks. Size the new tank by people, not square feet: 40 to 50 gallons for 2 to 4 people, 50 to 55 for 4 to 5, and 75 gallons or tankless for 5 or more. The gas vs electric and sizing guide adds the first-hour rating to that chart.

What will a new tank cost in Northwest Crossing?

For a 50-gallon tank, installed, expect $750–$2,800. Switching to tankless costs about $1,600–$4,500, plus a few hundred dollars more when a gas line or electrical upgrade is needed.

If your supply needs an expansion tank, that adds $225–$625. Every figure here is a typical range drawn from national cost guides, not a quote.

From your first text to a new tank

Text or call (830) 243-5644 with the tank's age if you know it, whether it runs on gas or electricity, and where it sits. You'll get a call right back and a price before the old tank is disconnected.

Ask for the license number too; a Texas master plumber's number starts with M.
