When You Need This
The longer you wait,
the worse it gets.
A tank water heater is the workhorse of residential plumbing — simpler, cheaper to install, and easier to service than tankless. When yours is leaking, rusting, or at end-of-life, the cost of waiting is a flooded garage. S.W.A.T. Plumbing carries the most common residential sizes (40, 50, 75-gallon, gas and electric) on the truck, pulls the city permit, and most standard swaps complete same-day with full code compliance.
Warning Signs
- Water pooling around the base of the tank (likely tank failure)
- Rust-colored water from hot taps
- Loud popping, banging, or rumbling when heating
- Hot water runs out too quickly compared to past performance
- Tank age 8+ years (gas) or 10+ years (electric)
- T&P (temperature & pressure) valve discharging
- Pilot light won't stay lit (gas units)
- Heating element or thermostat failure on an electric tank
Mission Operations
How we execute
from call to close.
- 01.
Size + Quote
Match Tank to Demand.
We confirm the right size (40, 50, 75-gallon) and fuel type (gas, electric, hybrid heat-pump) for your household. Most existing tanks are appropriately sized; sometimes a remodel or family change warrants a different spec. Flat-rate quote includes tank, install, permit, and old-unit haul-off.
- 02.
Prep + Permit
Permit, Shut-Offs, Old Unit Out.
We pull the city permit, shut off water and fuel, drain the old tank, disconnect supplies and venting, and haul out the failed unit. Floor protection, drip pans, and water containment stay in place throughout to keep the install area clean.
- 03.
Install
Mounted, Connected, Code-Compliant.
New tank goes in on a code-compliant pan, with proper venting (B-vent for atmospheric, sealed for power-vent), new flex supplies, T&P valve discharge piped to a safe drain location, and an expansion tank where local code requires it. Gas connection or electrical tie-in performed by a licensed plumber.
- 04.
Commission + Inspect
Filled, Lit, Tested, Signed Off.
Tank fills, gas relights or electrical energizes, temperature setpoint confirmed at 120°F (or your preferred safe setting), full leak inspection at every connection. City inspector signs the permit. Warranty paperwork registered, walkthrough completed, area cleaned.

S.W.A.T. Plumbing has dispatched to thousands of tank water heater installationcalls across North Texas. Here's what it actually sounds like.
“My A/C was leaking because of a backup in the main drain pipe. The tech Tyler was beyond communicative, patient, and tenacious to fix this. He stayed until almost 6p troubleshooting and sticking with the plan of action that freed the issue. Great guy and great service. As a bonus, I requested the soonest available service and when there was a cancellation that pulled my appointment forward by one day. One earlier day with A/C in Mya in Texas. Win! I was provided them through my home warranty service. I will definitely request them again. Tyler was the man!”
Marcus Combsa month ago“Daniel was great. He was Friendly, helpful, and informative. He took time to explain everything and walk me through my options. The SWAT team was great at keeping me informed on service time and expectations. Will 100% recommend.”
Achelle Evansa month ago“Over the weekend, I needed to call a plumber when the expansion tank on my water heater began leaking. I was unsure what might happen if the situation worsened, so I contacted my home warranty service to request assistance. I had previously informed them that if I ever needed plumbing services again, I preferred to work exclusively with S.W.A.T. Plumbing. On Monday morning, I received a call from Christi at S.W.A.T. Plumbing. She explained that although the plumber was finishing another job, she could have someone out later that afternoon. She told me that Scott H. would be handling the call and would contact me when he was on his way. About five minutes after our call ended, Christi called back to let me know that I would be Scott's next service stop. I really appreciated that level of communication. Less than forty five minutes later, Scott arrived at my home. Scott was professional from the moment he arrived. After a brief greeting, he immediately went to work. He confirmed my suspicion that the expansion tank was the problem, returned to his truck for tools and a replacement tank, and had the new tank installed within about twenty minutes. The repair was completed quickly, smoothly, and—most importantly—professionally. This was not my first experience with S.W.A.T. Plumbing, and it certainly will not be my last should the need arise again. This team truly knows how to take care of their customers. Thank you for inviting me to participate in this survey. I appreciate the opportunity to share my feedback. If you have any follow up questions or need additional information, please feel free to contact me.”
