Water Expansion Tanks in Tulsa, OK

Most Tulsa homeowners are surprised to learn this plumbing fact: the code now calls for a water expansion tank on any water heater installation here. Some might mistake it for an upsell, but in reality it is what stands between thermal expansion and your entire plumbing system when the heater is running hot. Wooten Knock-Out Plumbing installs and replaces expansion tanks across the Tulsa metro, usually in under an hour, always with upfront pricing.

What a Water Expansion Tank Does
Take an older open system, for instance. The heated water would simply push back into the city main and no one would be the wiser. Not so in today's home, where backflow protection and pressure regulators seal things off. Fire up the water heater and that expanding volume has nowhere to run, creating pressure spikes through every pipe, joint and fixture in the house. The expansion tank is there to put a cushion on it; its small bladder absorbs the spike and lets it go gently. Without one, or if it has gone bad, you are left with pressure hammering at your system dozens of times a day.


Signs of a Failed Expansion Tank
You will know if you have an issue. A relief valve on the water heater that starts to drip after each heating cycle is the telltale sign. Or perhaps the pipes tick and bang while the heater is on, or a gauge shows high pressure right after heating. There are other symptoms, like a tank that is waterlogged and heavy when you tap it, or early failures in your faucets and supply lines. We make a point of checking the tank on every water heater call, because the bladder has a way of giving out years before you are aware of it.
(918) 367-8887Code, Inspections, and Real Estate
Tulsa plumbing code requires thermal expansion control on water heater installations, which means an expansion tank comes standard with every water heater we install. If you are selling a home, an inspector will flag a missing or failed tank, and if you are buying one, it is worth knowing the fix is quick and reasonably priced. We handle the whole thing to code, with the right precharge set to match your home's pressure rather than just factory air.
Hard Water Makes It Matter More
With Tulsa's moderately hard water making matters worse by clogging relief valves and stiffening the system with mineral scale, a healthy expansion tank, the correct precharge and a working pressure regulator are essential to protect everything downstream, from the hot water lines to the dishwasher. We check all three in one visit.

Serving Tulsa and nearby communitiesFrequently Asked Questions
1How much does an expansion tank cost installed in Tulsa, OK?
It is an affordable bit of insurance compared to the cost of a burst supply line or a new water heater. We give you the installed price upfront, no surprises.
2How long do expansion tanks last?
We see five to ten-year life spans as typical. The bladder wears down without fanfare, so we test it during water heater service rather than wait for trouble. If it is in good shape we will say so and leave it be.
3Do I really need one if my house never had one?
If you have a backflow preventer or a pressure regulator, then yes, and under present Tulsa code an expansion tank is mandatory at the time of water heater replacement regardless. Physics does not make allowances for the age of the house.
4Can you check mine while doing other work?
Absolutely. It takes minutes and it is part of every water heater and hot water call we run.
