Water Heater Replacement in Rowlett

Every tank carries a rating label with a serial number, and in the serial number is the month and year it was made. Many makers use a letter for the month and two digits for the year, so a serial starting C16 would read March 2016. Makers differ, so a photo of the label is enough for a plumber to read it. The date is when it was made, which is usually within a year of when it was installed.

That date is the single most useful number in a replacement decision. The U.S. Department of Energy puts a storage tank's life at 10 to 15 years, and many installers plan on 8 to 12 where the water is hard. A tank in its first five or six years has a problem that is probably a part. A tank at 10 or 11 with a problem is a different conversation.

On December 26, 2015, a tornado classified EF-4 in Garland and EF-3 in Rowlett crossed the east side of the Dallas area. Rowlett's city manager reported on December 28 that the first damage assessment had covered 1,000 homes and found 854 impacted: 148 totally destroyed, 188 with major damage, 298 with minor damage and 220 affected. There were 23 injuries.

Rebuilding began in 2016, and CBS Texas found in 2024 that some lots were still not rebuilt after nine years. A heater fitted in a rebuilt home is therefore at most about 10 years old now, and many of those heaters are arriving at the middle and end of their life together, much as the houses were built together. If your house is one of them, the post on rebuilt Rowlett homes explains how to check the label and what a rebuild may have left out, such as a drain pan or an expansion tank.

A like-for-like replacement is estimated at $1,400 to $2,900, and one with attic access or code updates at $2,200 to $3,800. The job itself runs 3 to 5 hours and goes in this order: the label is read and the size chosen, the quote is written, the water and the power or gas are shut off, the old tank is drained and removed, the new tank is set and connected with new shut-offs and connectors, the relief line is run, an expansion tank is added where the system is closed, a pan goes under it where a leak could reach a ceiling, and the tank is filled, purged and tested at the tap with a thermometer.

Where the City of Rowlett requires a permit, we pull it and leave the work ready for inspection. Texas lets a property owner do plumbing in their own homestead without a license (Occupations Code 1301.051), but anyone doing it for a customer needs a license from the Texas State Board of Plumbing Examiners, and the work has to meet code either way.

The U.S. Consumer Product Safety Commission recommends 120 degrees. At that setting an adult takes about 5 minutes to reach a third-degree burn. At 130 it is about 30 seconds, at 140 about 6 seconds, and at 150 about 2. Because a dial isn't a thermometer, we measure the real temperature at the nearest tap after the install and adjust.

Our shop is 0.4 miles from Main Street in a straight line, and 1.8 miles from Pecan Grove Park and the Wet Zone on the same stretch of Main. A swap at the other end of Rowlett, in Waterview 4.4 miles away or Trails at Cottonwood Creek 5.4 miles away, takes the same crew and the same quote. We quote the same way everywhere, with the same lines.
