About this service
What Gas Water Heater Replacement in Carrollton actually involves
Gas Water Heater Replacement in Carrollton is the full removal and reinstallation of a natural gas or propane storage water heater, including the tank, gas flex connector, venting, T&P valve, expansion tank, and dielectric unions. We drain the old tank with a water heater drain pump, cut out corroded nipples with a tube cutter, and rebuild the connections in copper pipe or PEX tubing. Every joint gets Teflon tape or pipe dope, and we pressure-test before we leave.
Most Carrollton calls start the same way: a 10-to-15-year-old tank in a garage or attic closet finally gives out. You might see rusty water, hear popping noises from sediment buildup, or find a puddle near the base. If you need to replace gas water heater in Carrollton on short notice, we stock 40-, 50-, and 75-gallon units so you're not waiting on a warehouse run. Landlords in ZIP 30117 and 30116 get the same turnaround as homeowners.
- ✓ Hot water back same day
- ✓ Lower monthly gas bills
- ✓ Code-correct venting and gas work
- ✓ Warranty that actually transfers
What's included
What's included in a gas water heater replacement
Every replacement we quote covers the full job, not just the tank. You get removal, disposal, code-correct installation, leak testing, and warranty registration. If your setup needs an expansion tank, new venting, or a permit, we'll quote that upfront so there's no surprise on the invoice.
New gas tank and fittings
Your replacement tank comes with new dielectric unions, a gas flex connector, Teflon tape or pipe dope on every threaded joint, and a fresh T&P valve. We reuse existing venting only when it's code-compliant and in good condition.
Code-correct gas and venting
We follow NFPA 54 and the International Plumbing Code on gas line sizing, flue slope, and combustion air. If the old install cut corners, we correct it during the swap. That includes proper T&P discharge piping to within 6 inches of the floor.
Leak test and burner check
After the tank is set, we pressure-test every water joint and soap-test every gas connection. The burner fires, the flue draws, and we confirm the thermostat is set to 120 degrees Fahrenheit. You get hot water at the nearest fixture before we pack up.
Warranty registration and walkthrough
We register the manufacturer warranty on your new Rheem, A. O. Smith, or Bradford White tank and hand you the paperwork. Then we show you the shutoff valve, drain valve, and anode rod location so you know what to check down the road.
How it works
How our gas water heater replacement process runs
You describe the symptoms: leaking tank, no hot water, rusty water, or a pilot that won't stay lit. We ask the tank's age, size, and fuel type, then give you a realistic price range over the phone. If it's a simple thermocouple or T&P valve, we'll tell you that too instead of pushing a replacement.
A licensed plumber checks the tank, gas line, flue, and shutoff valve. We test the T&P valve, look for corrosion at the nipples, and confirm venting meets code. You get a firm quote before any work starts, and we note whether an expansion tank is required by local code.
We shut off the gas and water, drain the old tank with a pump, and disconnect the gas flex connector and water lines. The old unit comes out through the garage or attic access and goes on our truck. You don't pay a separate disposal fee or haul a 150-pound tank to the curb.
The new tank gets set level, connected with dielectric unions and copper or PEX, and vented to code. We solder or crimp the joints, open the gas valve, and leak-test every connection with a multimeter and soap solution. The burner fires, the flue draws, and we check the T&P valve one more time.
We set the thermostat to 120 degrees Fahrenheit, confirm hot water at the nearest fixture, and show you the shutoff and drain valve. Old parts and packaging leave with us. Total time on site is usually 3 to 5 hours, and you get the warranty paperwork before we pull out of the driveway.

Tools & methods
Tools and methods we bring to the job
Water heater drain pump
Moves 40 to 50 gallons of water out of the old tank fast, so we're not waiting on gravity through a garden hose. Cuts drain time from an hour to about 15 minutes.
Tube cutter and flaring tool
Cuts copper pipe cleanly and forms flare fittings for gas connections. A square cut is what keeps a soldered or flared joint from weeping six months down the road.
Soldering torch and pipe wrench
Used to sweat copper joints and break loose corroded nipples on the old tank. We keep a backup torch on the truck in case a fitting needs rework.
Multimeter and T&P valve tester
Checks thermocouple voltage, thermostat continuity, and confirms the T&P valve opens at its rated pressure. Diagnostic tools, not guesswork.
Expansion tank and dielectric unions
Dielectric unions stop electrolysis between copper and steel. An expansion tank absorbs pressure spikes on closed systems, which protects the new tank and the T&P valve.
Gas flex connector and brass fittings
We use a new gas flex connector on every install, never the old one. Brass fittings, Teflon tape, and pipe dope go on every threaded joint before it's tightened.
Real results
Before and after.
Gas Water Heater Replacement
Leaking 50-gallon tank in a Downtown Carrollton garage
A 13-year-old gas tank was weeping at the base and leaving a puddle under the unit. The homeowner was mopping it up daily and had already seen rusty water at the kitchen tap. The anode rod was completely gone.
After: We drained and removed the old tank, installed a new 50-gallon Rheem with fresh dielectric unions and a gas flex connector, and leak-tested every joint. Total time on site was 4 hours. Hot water was back the same afternoon.

Gas Water Heater Replacement
No hot water in a Castle Hills home with a failed thermocouple
The pilot light kept going out, and the homeowner was relighting it every morning. The tank was 11 years old, and the gas valve was sticking. A repair would have bought maybe a year.
After: We replaced the tank with a 50-gallon Bradford White, corrected a venting slope issue the original installer left behind, and confirmed the burner fired cleanly. The family had hot water by dinner.

Gas Water Heater Replacement
40-gallon tank swap between tenants near Josey Ranch
A rental property needed a new gas tank during a 48-hour turnover. The old 40-gallon unit was 14 years old and had a corroded T&P valve that was weeping. The property manager needed it done before the next tenant moved in.
After: We installed a new 40-gallon Rheem, replaced the T&P valve and expansion tank, and registered the warranty. The job was finished in under 4 hours, and we sent photos to the property manager for the file.

Problems we solve with gas water heater replacement in Carrollton
Most gas tank failures announce themselves before they flood the garage. Here are the calls we run most often, and what happens if you wait too long to book the replacement.
Ask a pro →Leaking tank with water pooling at the base
We shut off the gas and water, drain the tank, and replace it the same day. If the leak is from a fitting or the T&P valve instead of the shell, we'll repair that and save you the cost of a new unit.
No hot water and a pilot light that won't stay lit
We diagnose the thermocouple, gas valve, and thermostat on site. If a repair will hold, we do it. If the tank is at end of life, we swap it for a new gas unit and confirm hot water before we leave.
Rusty water and popping noises from sediment
We replace the corroded tank and install a fresh anode rod in the new unit. For Carrollton homes with hard water, we'll also recommend a flush schedule and, if needed, a scale-reduction valve to slow the next buildup.
Failed T&P valve or expansion tank
We replace the T&P valve with an OEM-rated part, test the discharge line, and swap the expansion tank if the bladder has failed. If the tank shell shows corrosion, we'll quote a full replacement instead of a partial fix.
Transparent pricing
What gas water heater replacement costs in Carrollton
$950 - $2,400 installed, depending on tank size, venting, and access
Typical 2026 pricing in Carrollton runs $950 to $2,400 installed, depending on tank size, venting, and whether an expansion tank or permit is required. A standard 40- or 50-gallon swap with existing code-compliant venting sits near the lower end. Power vent, direct vent, or attic installs with new flue work land higher. We quote upfront, and the price you hear on the phone is the price on the invoice. Old tank removal and disposal are included.
You're paying for a code-correct install, a new T&P valve, leak testing, and old tank disposal, not just a box. A cheap install that skips venting or reuses a corroded gas connector costs more the second time around.
•affects cost
A 40-gallon gas tank costs less than a 75-gallon unit, and high-efficiency or power vent models cost more than standard atmospheric tanks. We'll size the unit to your household so you're not paying for capacity you won't use.

If your existing flue is code-compliant and in good shape, we reuse it. If it needs a new run, a power vent conversion, or a direct vent kit, that adds labor and materials. We check venting before quoting so there's no surprise.

A bigger tank or a tankless upgrade may need a larger gas line. Upsizing a half-inch run to three-quarter inch adds cost but prevents the burner from dropping out under load. We measure before recommending.

Many Carrollton homes on a closed system need an expansion tank, and we replace the T&P valve on every install as a safety measure. Both are small line items that protect the new tank and keep the install code-correct.

What Carrollton customers say
★★★★★
“Our 12-year-old gas tank let go on a Saturday morning. I called at 9 a.m. and had a new 50-gallon Rheem running by 2 p.m. The plumber showed me the rusted anode rod he pulled out and explained why it failed. Clean work, no mess left in the garage, and the price matched the phone quote.”

“I manage three rentals near Josey Ranch and needed a gas tank swapped between tenants on short notice. They handled the install, registered the warranty, and sent me photos of the finished work for my records. The tenant had hot water that evening. I've used them twice since.”

“We kept running out of hot water with a 40-gallon tank and a full house. They checked the gas line, recommended a 50-gallon Bradford White, and had it installed in about four hours. No more cold showers at 7 a.m. They also fixed a venting issue the original builder left behind.”
