What's included
What our tank replacement includes
Every replacement is quoted as a complete job, not a parts-and-labor estimate. Here is what comes standard, and where we flag an add-on before we start so there is never a surprise on the invoice.
New tank and fittings
A new storage water heater in the correct size and fuel type, plus fresh dielectric unions, flex connectors, and a new T&P relief valve. We do not reuse old fittings that are already corroded or out of spec.
Old tank haul-away
We drain, disconnect, and carry the old unit out of your home and off your property. No tank sitting on the curb, no separate disposal fee, no wrestling a 150-pound cylinder down your attic stairs.
Code-correct venting check
We inspect the flue, draft hood, and clearances against Uniform Plumbing Code and ANSI Z21.10.1. If the existing venting is undersized or degraded, we tell you before the install and quote the fix as a separate line.
Pressure and leak testing
After fill, we purge the air, check every joint with a pressure gauge, and run the unit to temperature. We do not leave until the burner or element cycles correctly and the floor under the tank is dry.
Warranty and walkthrough
You get the manufacturer warranty paperwork, our labor warranty, and a short walkthrough of the shutoff valve, temperature setting, and anode rod schedule. We answer questions until you are comfortable running the unit.
Service overview
What tank replacement Katy TX actually involves
Tank replacement Katy TX means removing your old storage water heater and installing a new one, sized and vented to match your home. We drain the tank, disconnect the gas or electric supply, cut out the old flex connectors, and inspect the shutoff valve, expansion tank, and venting before anything new goes in. Then we set the new unit, reconnect the T&P relief valve and dielectric unions, fill it, bleed the lines, and fire it up. Most jobs take two to four hours, and we haul the old tank away the same day.
Katy homes deal with hard water scale and sediment buildup that quietly eats a tank from the inside. Once the anode rod is spent and the glass lining is compromised, you are looking at a leaking tank, rusty hot water, or no hot water at all. If you have been searching tank replacement Katy TX near me after a cold shower, you are in the right place. We also cover water heater tank replacement Cane Island and the surrounding neighborhoods, so a failed tank never turns into a week of cold mornings.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How our replacement process runs
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone diagnosis
You call (281) 326-6032 and describe what you are seeing: a puddle, rusty water, no hot water, or a pilot light that keeps going out. We ask the right questions, give you a ballpark range, and book a same-day or next-morning window that fits your schedule.
On-site inspection
A licensed plumber checks the tank, the T&P valve, the venting, the gas line or electrical circuit, and the shutoff. We confirm the correct size and fuel type, then hand you a firm price before any work starts. Fifteen to twenty minutes, tops.
Drain and removal
We shut off the supply, drain the old tank with a hose and pump, disconnect the flex connectors, and cut the old fittings free. The dead unit gets carried out, not left on your curb for the city to deal with.
Install and test
The new tank goes in with fresh dielectric unions, a new T&P relief valve, and a properly sized expansion tank. We fill it, purge the air, check every joint with a pressure gauge, and run the burner or element until the water hits temperature.
Walkthrough and cleanup
We show you the new unit, the shutoff, and the settings, then haul away the old tank and any packaging. You get a copy of the warranty paperwork and a reminder for your first anode rod check. Total time on site: usually under four hours.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Pipe wrench and tube cutter
Used to break loose old unions and cut out corroded nipples cleanly, so the new connections seat properly without stressing the tank fittings.
Soldering torch
For copper repairs and adapting existing supply lines when the old fittings cannot be reused. We protect the surrounding framing with a heat shield on every sweat joint.
Multimeter and element wrench
We test voltage at the element and thermostat before condemning a tank, and use the element wrench to swap electric heating elements when a repair makes more sense than replacement.
Thermocouple tester
Confirms whether a gas pilot failure is the thermocouple, the gas valve, or the orifice. That test decides whether you need a $40 part or a whole new tank.
Water heater flush kit and descaling pump
For tankless descaling and for flushing sediment out of storage tanks. Katy's hard water makes this equipment essential, not optional.
Pressure gauge and T&P valve tester
We verify incoming pressure and test the relief valve on every install. A T&P valve that will not open is a safety issue, and we replace it as part of the job.
Use cases
When to call for a replacement
These examples show how the service framework adapts rather than forcing every call through one repair.
Attic tank swap in Elyson
A failed electric tank in a second-floor attic closet, with no hot water for three days. The access opening was narrow, and the old unit had to be drained and broken down to get it out without damaging the ceiling. → New 40-gallon electric unit installed with a new heating element and thermostat, tested with a multimeter, and vented to code. Total time was about five hours including removal. The homeowner had hot water that evening.
Emergency Sunday replacement in Firethorne
A tank let go on a Sunday morning, sending water across the garage floor and toward the laundry room. The homeowner called at 8 a.m. with no hot water and a growing puddle. → We walked them through shutting off the supply and gas, arrived by 10 a.m., and had a new 50-gallon gas tank running by early afternoon. The old unit was removed and the floor was dried before we left.
Problems we solve
Problems a new tank puts behind you
Most tanks do not fail without warning. They give you signs for weeks, and then they quit. Here are the problems we hear about most from Katy homeowners, and what a replacement does about each one.
Leaking tank flooding the garage or closet
We shut off the supply, drain the tank, and install a new unit with a drip pan and drain line where code requires it. Most emergency calls are resolved the same day, and we haul the failed tank away.
No hot water or water that never gets hot
We test the element, thermostat, and thermocouple first. If the tank is sound, we repair it. If corrosion or a failed lining is the cause, we quote a replacement and usually install it the same day or the next morning.
Rusty or metallic-smelling hot water
We confirm the diagnosis by checking the anode rod and drain valve. Once the tank itself is the source, replacement is the only fix. A new tank plus a quality anode rod restores clean hot water immediately.
Popping, rumbling, or banging from the tank
If the tank is young, a flush with a descaling pump and solution buys years. If it is old and already noisy, we replace it and set you up on a yearly flush schedule so the new one lasts.
Pricing process
What tank replacement costs
$1,100 - $2,400 installed, depending on tank size, fuel type, and access
Tank size and fuel type
A 40-gallon electric tank costs less than a 75-gallon gas unit. Larger tanks hold more material and take longer to install, and gas units add venting and combustion testing to the job.
Location and access
A garage swap is the simplest job. Attic units, tight closets, and second-floor installs add labor because of the extra hands, protection, and time needed to get the old tank out and the new one in.
Venting and code upgrades
If the existing flue is undersized or the clearances are wrong, we correct it to Uniform Plumbing Code. That is a real cost, but it is also a safety requirement, and we flag it before the install starts.
Customer reviews
What Katy homeowners say
★★★★★
“Our 12-year-old tank let go on a Saturday morning and flooded the garage. I called at 8 a.m. and had a plumber here by 10. He showed me the corrosion at the bottom of the old tank, quoted a flat price, and had a new 50-gallon Rheem running by early afternoon. Hauled the old one off and cleaned up the mess. Fair price, no upsell.”
★★★★★
“We kept getting rusty hot water and figured it was the end of the tank. They came out, checked the anode rod and the T&P valve, and confirmed the tank was done. Replaced it the next morning in about three hours. They also added an expansion tank since our neighborhood has a backflow preventer. Hot water has been perfect since.”
★★★★★
“Attic unit, tight space, and I was worried about the cost. The tech explained the venting issue, gave me a firm number that included new flex connectors and a drip pan, and finished the same day. He walked me through the shutoff and the warranty paperwork before he left. No surprises on the invoice.”
How much does tank replacement cost in Katy TX?
Typical 2026 pricing in this area runs $1,100 to $2,400 installed, depending on tank size, fuel type, and whether we need to update venting or add an expansion tank. A standard 50-gallon gas unit in a garage sits near the lower end. Attic installs, code upgrades, and hard-to-reach closets push the number up. We give you the exact figure on site before any work begins.
How long does tank replacement take in Katy?
Most replacements take two to four hours from arrival to hot water. A straightforward garage swap with good access is often done in about two hours. Attic units, tight closets, or jobs that need new venting can run closer to five. We schedule a window, not a whole day, and we call ahead when we are on the way.
Should I replace my tank or repair it in Katy Texas?
If the tank itself is leaking or corroded, replacement is the only real fix. Repair makes sense when the problem is a failed heating element, thermostat, thermocouple, or T&P relief valve on a tank under eight years old. Once a unit passes ten years and shows rust or sediment at the drain valve, putting money into repairs rarely pays off.
