Water Heater Repair in Arlington, TX

Tank water heaters last 8 to 12 years. Tankless go 15 to 20 if you flush them every year. DFW's hard water knocks 1 to 3 years off either if the unit never gets serviced. If yours is past 10 and acting up, you're better off replacing it than throwing money at repairs.

Under 10 years old, one failed part? Repair it. Past 10 years with the tank itself leaking, multiple repair calls, or your gas bill creeping up? Replace it. The plumber on the call will tell you straight which side you're on.

Popping or rumbling? That's sediment trapped under the heating element, flashing to steam. Real common in DFW because of the hard water. A flush usually clears it. If the noise comes with rusty water or shorter showers, the tank's probably done.

Gas unit? Probably a pilot light, thermocouple, or gas valve. Electric? Check the breaker first, then the heating element. Either way a licensed plumber can tell you in 30 minutes. Most fixes are done the same visit.

Sulfur bacteria reacting with the magnesium anode rod inside your tank. Swap the anode for an aluminum/zinc one and the smell usually goes away. If the cold water smells too, the problem is your water supply, not the heater.

A T&P valve that drips usually means high water pressure or thermal expansion. The fix is normally an expansion tank. Leaking hard and constant? Don't touch it. That valve is the only thing keeping your tank from blowing up. Call a plumber today.

Rule of thumb: 40-gallon tank for 1 to 3 people, 50 for 3 to 4, 65 to 80 for 5 or more. Tankless is sized by gallons-per-minute, not gallons stored. The plumber will size yours based on your bathrooms, fixtures, and water temperature coming in.

DFW water is loaded with calcium and magnesium. That stuff settles at the bottom of tank heaters and crusts up the heat exchangers in tankless units. Result: less efficiency, more popping, shorter lifespan. Flush your tank once a year. Descale your tankless once a year. Both add years.

Don't. Texas requires a licensed plumber for water heater installs, and most DFW cities require a pulled permit too. DIY voids your home insurance and fails inspection at resale. For gas units it's genuinely dangerous. The few hundred bucks you save isn't worth the risk.
