Bulwark Plumbing handles water heater replacement for gas and electric, tank and tankless heaters across Grapevine and the DFW metroplex. We size the new heater to the house, install it to code, pull the permit where the city requires one and haul the old tank away.
Water heater replacement is the honest answer when the heater is past about 12 years old, leaking from the tank itself, or rusting at the base. A heater under about 8 years old with a failed part is usually worth fixing instead, and between 8 and 12 years you should see both prices.
A proper water heater replacement sizes the new heater to the house, includes the drain pan, expansion tank, relief valve line and venting the location calls for, and is permitted where the city requires it. Bulwark Plumbing quotes it as a written flat price before any work starts, from our shop at 720 Industrial Blvd in Grapevine.
Water heater replacement makes sense when the tank itself is finished, not just a part on it. Our rule of thumb is simple. Under about 8 years old with a failed element, thermostat or valve, fix it. Past about 12 years, leaking from the tank itself, or rusting at the base, replace it. In between, the decision depends on which part failed and the condition of the tank.
If the heater is young and the problem is a single part, we will say so and point you to water heater repair rather than sell you a new heater. When both a repair and a water heater replacement are legitimate, you get a written flat price for each and choose. Our article on whether a leaking water heater should be repaired or replaced walks through each leak point.
North Texas water is hard, and hard water shortens water heater life. Minerals drop out as the water heats and settle as scale on the tank bottom and on the elements. The burner or lower element then has to heat through that crust, the bottom of the tank runs hot, and the steel ages faster than it would in soft water.
That is why a 10 year old heater here has often lived harder than its age suggests, and why the 8 to 12 year band matters when you weigh water heater replacement against another repair. Rumbling or popping from the tank is the sound of that sediment. On an old tank that has never been flushed, it usually means the bottom has been running hot for years.
Shut off the gas or power and the cold inlet, then call. Otherwise, book a water heater replacement estimate online and have it confirmed on the spot.
A tank is sized by its first hour rating, the amount of hot water it can deliver in an hour of heavy use, matched to how the household actually uses water. Gallon capacity alone does not tell the whole story. Two heaters with the same tank size can have different first hour ratings, especially between gas and electric.
On a water heater replacement we look at how many people shower in the morning, whether there is a large soaking tub, and whether the old heater kept up. If it never did, a like for like water heater replacement just buys the same problem again. If the old heater was larger than the house needs, a smaller one can cost less to run. We also measure the space, because a larger tank or a taller model does not always fit where the old one stood, especially in a closet or attic.
On most water heater replacement jobs the new heater uses the same fuel as the old one, because that is what the house is set up for. A gas heater needs a gas supply sized for it, a vent and combustion air. An electric heater needs a dedicated circuit sized for its elements. Keeping the same fuel keeps a water heater replacement simple.
Switching is possible but it is real work. Electric to gas means running gas to the location, adding venting and making sure the space has the combustion air the heater needs. Gas to electric can mean a new circuit and sometimes electrical panel work. We check what the house has before quoting a fuel change, and our gas line crew handles new runs and pressure testing where a new gas supply is needed.
Sometimes, and a water heater replacement is the natural time to ask. A tankless heater gives continuous hot water and takes up far less space, but it costs more to install and needs regular descaling in hard water. A tank heater costs less up front and is simpler to service. Neither is right for every house.
The detail that surprises people is gas. A gas tankless unit burns far more gas at full fire than a tank does, so the line that fed the old tank is often too small. Converting usually means upsizing the gas line, new venting, and an outlet for the controls. If you are weighing that kind of water heater replacement, our page on tankless water heaters covers sizing, scale and the honest comparison in more detail.
Most water heater replacement jobs put the new heater where the old one stood, because the water lines, gas and venting already run there. Each location has its own requirements.
Moving a heater to a new location is possible, but it means new water lines, and for gas, a new gas run and vent. We price that as its own item so you can see what the move adds.
A proper water heater replacement includes the safety items an older installation is often missing. Requirements vary by city and by where the heater sits, so treat this as what we check, not a code book.
Often, yes. Many DFW cities require a permit and an inspection for a water heater replacement, especially for gas units, and the rules differ from city to city. Where the city requires it, Bulwark Plumbing pulls the permit and the installation is inspected.
That inspection is worth having. It gives you a record of a compliant installation when you sell the house, and it means a second set of eyes has checked the venting, gas connection and relief valve line. Every technician is a Bulwark employee working under Texas State Board of Plumbing Examiners license 47173, with Jared J. Allen as Responsible Master Plumber. We never subcontract a water heater replacement.
A typical water heater replacement follows the same order every time, so you know what is happening in your house.
It depends on the heater you need and what is on the trucks. A common tank size in gas or electric is a different situation from a specific tankless model or an unusual size that has to be ordered. The dispatcher tells you the arrival window when you book, and the technician tells you before starting whether the water heater replacement can be finished that visit.
If the old tank is leaking, do not wait for the appointment to stop the water. Turn off the gas control or the breaker, close the cold water valve above the heater, and call. Our 24/7 emergency line is answered around the clock, and a licensed plumber will tell you whether it needs a truck tonight.
Every water heater replacement installed by Bulwark Plumbing carries a 2 year labor warranty. The manufacturer warranty on the heater itself is registered in your name, not ours, so it follows the house and does not depend on us.
Keep the paperwork we leave after the water heater replacement. Manufacturer warranties typically depend on the heater being installed correctly and maintained, which is one more reason the code items above are part of every water heater replacement rather than optional extras.
Flush a tank heater about once a year and have the anode rod checked every few years. Flushing drains out the sediment that hard water drops in the bottom of the tank, and a healthy anode rod keeps the tank from rusting. Set the thermostat around 120°F unless you have a reason to run it hotter, keep the area around a gas heater clear, and check that the relief valve is not dripping. That routine is the cheapest way to push the next water heater replacement further out.
It depends on the type and size of heater, gas or electric, where it is installed, and what the installation needs to meet code, so we do not publish a number that would not hold for your house. What you can rely on with every water heater replacement:
We cover 52 cities within about 25 miles of the Grapevine shop, including Grapevine, Southlake, Colleyville, Keller and Flower Mound. Book a water heater replacement estimate online in about a minute, or call for anything leaking. If the water on the floor turns out not to be the heater at all, our leak detection service finds where it is coming from.
Replace a heater that is past about 12 years old, leaking from the tank itself, or rusting at the base. A heater under about 8 years old with a failed element, thermostat or valve is usually worth fixing. Between 8 and 12 years it depends on the part and the tank, and Bulwark Plumbing gives you a written price for both options so you can decide.
A like for like water heater replacement is usually a single visit. Moving the heater, changing fuel, switching to tankless, or bringing an older installation up to code adds time. The dispatcher tells you what to expect when the visit is booked, and the technician confirms it before starting.
Many DFW cities require a permit and an inspection for a water heater replacement, especially for gas units. Requirements differ from city to city. Where the city requires it, Bulwark Plumbing pulls the permit and the installation is inspected.
Not automatically. A water heater replacement is the moment to check whether the old size still fits the house. If the household has grown, a larger tub went in, or the hot water has been running out, a bigger tank or a tankless unit may suit better. If the old heater was oversized, a smaller one can cost less to run.
Yes, but it is more than a swap. Electric to gas needs a gas supply, venting and combustion air. Gas to electric needs a circuit sized for the heater, which may mean electrical panel work. We check what the house has before pricing that kind of water heater replacement.
We drain it, disconnect it and haul it away as part of the water heater replacement, so nothing is left in your garage or driveway.
