Should you repair or replace a leaking or cold water heater in Tulsa? Often you can repair it. A leak from the flex connectors on top is common and an easy repair. A tank that is split inside has to be replaced. If it is not heating, we test the gas control valve, and because a lot of tanks are still under warranty, the part is often free. Tank water heater repairs start at $500, and you get your flat-rate price before any work starts.
What we check first, in Michael's words
"Usually when we get on site, if the water's off to the water heater, we'll go and turn it back on, check, see what's leaking." The flex connectors on top are a very common leak, "and that's an easy repair to do, so they don't have to do a full replacement." If the tank is split internally, that's when it has to be replaced.
If it's not heating, "we'll get out our tester and we'll start testing the gas control valve, and if we need to, we'll call tech support, 'cause a lot of times the water heater's under warranty." That's AO Smith on tank water heaters and Navien on tankless units. "A lot of times the parts will be under warranty, so then that's free for the customer."
Our rule on gas control valves
When we change a gas control valve, we change the burner assembly with it, on the same visit. That's Michael's rule for every gas control valve we replace.
Why Tulsa tanks build up sediment
Tulsa water is hard. According to the City of Tulsa, water from the A.B. Jewell treatment plant averages 8.2 grains per gallon and water from the Mohawk plant averages 5.2 grains per gallon. Those minerals settle in the bottom of a tank. That is the popping noise you hear, and it is why we suggest flushing your tank every year.
Repair or replace: how we look at it
| What we find | Usually | Why |
|---|---|---|
| Leak at the flex connectors on top | Repair | Common and an easy repair, no full replacement needed |
| Not heating (gas) | Test, then repair | We test the gas control valve; the part is often under warranty |
| Gas control valve replaced | Burner assembly too | Both go in on the same visit |
| Tank split internally | Replace | A tank leaking from inside can't be repaired |
| Heavy rust at the top fittings or in the combustion chamber | Replace | We suggest replacing sooner when we see this |
| Tank 10 to 15 years old needing a major repair | Talk options | Plan on replacing a tank around 10 to 15 years |
When we suggest replacing
- What we suggest: plan on replacing a tank water heater around 10 to 15 years.
- We suggest replacing sooner only with heavy rust around the top fittings where the flex connectors attach, or inside the combustion chamber.
- If you're replacing, it's worth hearing about tankless too. With a yearly flush, a tankless unit with a stainless steel heat exchanger can last 25 years or more, and one with a copper heat exchanger 15 to 20 years. That is what we typically see, not a guarantee. See Tankless Water Heaters and our water heater replacement guide.
- Replacement tanks we install are AO Smith: 40-gallon from $2,575, 50-gallon from $2,755, 75-gallon from $5,259.
Repair or replace, the tech gets paid the same
"If your water heater can be repaired or needs to be replaced, the technician gets paid the same." Our techs are paid hourly, not on commission, so the recommendation is about your tank, not a sales target.
What a visit costs
- Service call $89, and we waive it when you go ahead with the repair.
- Tank water heater repairs start at $500, depending on whether we replace the control valve, the pilot assembly or both.
- Your exact flat-rate price is quoted upfront before any work starts.

Straight Answers
Does a water-heater leak always mean replacement?
Not always. A leak from the flex connectors on top is common and an easy repair. If the tank is split internally, replacement is necessary.
What do you check when the water heater is not heating?
We bring out our tester and check the gas control valve first.
Do you replace the burner assembly when you replace the gas control valve?
Yes. Every time we change a gas control valve, we change the burner assembly with it.
Does the technician have an incentive to replace it?
No. The technician is paid the same whether your water heater is repaired or replaced.
How do I know if I should repair or replace my water heater?
A standard tank usually lasts 10 to 15 years. If yours is older and the fix would be major rather than something simple like a flex connector, it's worth talking through options, including tankless.
How long does a water heater last in Tulsa?
Plan on about 10 to 15 years. Replace sooner if you see heavy rust where the pipes connect on top or inside the burner area.
Why is my water heater making popping noises?
Sediment has built up on the bottom of the tank and water trapped under it is boiling. Flushing helps, but heavy buildup shortens the heater's life.
Why do I have no hot water?
On a gas unit it is usually the pilot, thermocouple or gas control valve. On an electric unit it is usually a heating element or thermostat.
How much does water heater repair cost?
Tank repairs start at $500, depending on whether we replace the control valve, the pilot assembly or both. The $89 service call is waived when you go ahead with the repair, and your flat-rate price is quoted before work starts.
Is my water heater part covered by warranty?
A lot of times it is. We call the manufacturer's tech support, and if the heater is under warranty, the part is free for you.
What brands do you work on?
We install AO Smith tank water heaters and Navien tankless units.
Why does Tulsa water cause water heater problems?
Tulsa water is hard, 5.2 to 8.2 grains per gallon depending on the treatment plant, according to the City of Tulsa. The minerals settle as sediment, so we suggest flushing every year.
