Repairing a tank
A tank that still holds water may only need a new heating element, thermostat or valve. The plumber inspects the heater and says whether a repair is worth making.
Hot water that has run out, a drip at the base of the tank or a heater that no longer heats can lead to a repair, a replacement or a tankless switch. Tell us when the trouble started and what the tank is doing, and get your free estimate.
Heater repair and replacement choices come first, followed by DeSoto’s permit and garage rules and ways to size a heater or check its age.

A tank that still holds water may only need a new heating element, thermostat or valve. The plumber inspects the heater and says whether a repair is worth making.
When the tank itself leaks, a replacement goes in. Gas and electric models differ in venting, gas supply and wiring, so the new unit is matched to what the house already has.
Switching to tankless removes the tank. The unit warms water as it passes through, so its size is a matter of gallons per minute, and the gas line and venting or the electrical service have to suit it.
A tankless unit can also need service. A plumber can read an error code, check the venting and the gas or power supply, and replace a worn part.
DeSoto lists replacing or adding a water heater as permit work. State law agrees for a city of more than 5,000 people, which regulates water heaters, pipes, tanks, valves and fixtures by ordinance, and its short exception list leaves out new heaters.
For a heater swap in DeSoto, getting the permits the codes call for and requesting the inspections is the Responsible Master Plumber’s part of the job, as the Texas State Board of Plumbing Examiners lays it out.
A gas water heater in the garage, or reachable from it, must be raised 18 inches above the floor when it is replaced. An electric water heater is not required to be elevated.
Hot water drawn in a household’s busiest hour sets tank size. For a tankless unit, what counts is gallons per minute running at once plus how far the water must be heated.
Both numbers can be worked out before you phone. The first-hour rating comes out of the water heater size calculator, while the flow a tankless unit needs is found with the tankless flow calculator, which sets the incoming water temperature from the town’s 36°F January low, putting DeSoto at 52°F.
The serial number decoder turns the number on a heater’s rating label into a manufacture year, brand by brand, so you know its age when repair and replacement are both on the table.
