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 our techs are paid hourly, so they get paid the same whether you repair or replace.
Start with the leak
The flex connectors on top are a very common source of leaks, and that's an easy repair, so we don't have to do a full replacement. If it's split internally, that's when we would obviously need to replace it.
When there is no heat
If it's not heating, we'll usually get out our tester and start testing the gas control valve.
Brands we install: we install AO Smith water heaters and Navien tankless units.
Repair or replacement
If your water heater can be repaired or needs to be replaced, the technician gets paid the same.
When repair isn't the right call
A standard tank water heater usually lasts 10 to 15 years, so if yours is older and the fix would mean a full internal replacement rather than something simple like a flex connector, it's worth discussing options, including a tankless unit, which can last 20 to 30 years with an annual flush by a licensed plumber.
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.
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 | Test, then repair | We test the gas control valve; the part is often under warranty |
| 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 |
Leaks and no heat, explained by Michael
"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 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 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."
On gas control valves, Michael's rule is to change the burner assembly every time we change the valve.

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, so full replacement isn't needed, but if the tank is split internally, replacement becomes necessary.
What do you check when the water heater is not heating?
When a water heater isn't heating, we typically bring out our tester and check the gas control valve.
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 my water heater or replace it?
A standard tank water heater usually lasts 10 to 15 years, so if yours is older and the fix would mean a full internal replacement rather than something simple like a flex connector, it's worth discussing options, including a tankless unit, which can last 20 to 30 years with an annual flush by a licensed plumber.
How long does a water heater last in Tulsa?
Most tank water heaters should be replaced at about 10 to 15 years. Replace one sooner if you see heavy rust where the pipes connect on top, on the flex connectors, 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 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.
Is my water heater part covered by warranty?
A lot of times it is. When a part fails, we call the manufacturer's tech support, and if the water heater is under warranty, the part is free for you.
What brands of water heaters 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, averaging 5.2 to 8.2 grains per gallon depending on the treatment plant, according to the City of Tulsa. The minerals settle in the tank as sediment, so we suggest flushing it every year.
