Leak repair for Fort Worth, TX water heaters in garages, attics and closets, from the Stockyards to the streets around TCU, plus Arlington, Dallas and Plano. We trace the leak to a valve, a fitting or the tank, fix it, and replace heaters whose tanks have failed. Calls answered 24/7.
Water heater leak repairs in Fort Worth, TX cover garage, attic and hall-closet heaters, and every one starts the same way. We pin down the source first: relief valve, drain valve, a top fitting or the tank shell. Swapping a valve or a fitting keeps the heater; a tank rusted through means a new heater and a city permit.
Supply lines in garages, attics and outside closets
NOAA's 1991-2020 normals for Fort Worth Meacham Field record 32.8 nights each year when the low drops to 32 F or colder. Bare copper and flex lines beside a garage or attic heater can split in a hard freeze, so we check those lines first on a winter call.
The tank bottom and the relief valve seat
Fort Worth Water's 2025 report puts hardness at 6 to 9 grains per gallon. That is moderate, yet over the years it leaves scale in the tank and a mineral film on the relief valve seat, which can stop the valve closing tight.
Attic platforms and the pan underneath
The same NOAA station averages 24.1 days a year at 100 F or hotter. When an attic heater's pan overflows or its outlet line clogs, the first sign is often a brown ring on the drywall below, so we inspect the pan on every attic job.
Tank seams, the base and the top nipples
The Census Bureau puts the median year built for Fort Worth homes at 1994. The heater's own age matters more, so we read the date code on the label before we talk about repair or a new tank.
We sort Fort Worth calls by where the water shows up, and our statewide leak guide explains each source and lists typical costs.
We put a gauge on a hose bib before we touch the valve, because a closed system with no expansion tank makes a new valve drip too. If pressure reads normal, we replace it.
A drain valve that drips at the spout or around its threads gets replaced. Before we fit the new one, we flush scale out of the tank, since sediment is often what kept the old valve from seating.
Crust on the nipples or a damp shut-off stem means a joint is weeping. We drain below the fitting, replace the nipple, union or valve, and dry the jacket to confirm the leak was only on top.
On an electric tank, water around an element cover usually means a failed element gasket. We switch off the breaker, drain below the port, fit a new gasket and element, and refill the tank before the power goes back on.
A tank that leaks through its shell is replaced. We drain and remove the failed heater and set a new gas or electric unit. Our repair or replace guide shows how we make that call.
Fort Worth's permit rule reaches further than in many Texas cities, because it names repairs as well as replacements. Here is what applies before the work starts.
The City of Fort Worth residential permit guide lists changing, moving or repairing plumbing, water heaters included, as work that needs a plumbing permit. So a fix to the heater itself sits under that rule, the same as a full replacement.
Permits for heaters at Fort Worth addresses come from the City of Fort Worth Development Services. When the Texas plumbing board says to check locally on permits and inspections, this is the office it means for anyone inside city limits.
Under Texas Occupations Code section 1301.051, an owner working on the homestead they own needs no plumbing license. That state exemption says nothing about city permits, so call Development Services before you swap your own heater.
Anyone working on your heater should give you a license number. The Texas State Board of Plumbing Examiners says a Master Plumber number starts with M, and its online search shows whether that license is current with insurance on file.
Fort Worth sees more freezing nights than Houston or San Antonio, so a heater in an unheated garage or attic needs a few minutes of work before winter.
Fit foam pipe sleeves on the bare hot and cold pipes over the tank, plus any line running along an outside garage wall.
On a freezing night, a closed door holds in the heat that the tank gives off, which keeps the lines beside it warmer.
A heater switched off for a trip loses the warmth that protects its own pipes, so use its vacation setting if it has one.
A split can happen on the line before the heater's cold valve, so know where your house main is before the first hard freeze.
Frozen copper often starts dripping only once it warms up, so check the heater and its pan the morning after a freeze.
Tell us your city, whether the heater is gas, electric or tankless, and where the water is showing.

These are the questions Fort Worth owners and renters bring up most when water reaches the floor.
Shut the valve on the cold line above the heater so no new water enters the tank. Then set the gas control to off, or flip the breaker on an electric unit. With any gas odor, go outside and phone the gas company.
