40 & 50 Gallon Gas Tanks
Standard atmospheric vent swap. New flex connectors, dielectric unions, a proper drip leg and a fresh T&P discharge line to code.
Most tank swaps are done by afternoon. Tankless gets sized off your actual fixture count and winter inlet temperature — not off a brochure.

Kettlewell started in 2016 doing warranty swaps for a supply house on the south side. We got fast at it, then we got picky about it — swept bends instead of stacked elbows, unions where the next person will need them, a shutoff you can actually reach.
We don't do drains and we don't do furnaces. Water heaters and the pipe around them, every day, which is the reason the truck already has your part on it when we pull up.

Straight prices on the common work. Anything unusual gets a firm quote once we've seen the gas line and the venting.

Standard atmospheric vent swap. New flex connectors, dielectric unions, a proper drip leg and a fresh T&P discharge line to code.

Same-day swap on 30 to 80 gallon electric. New elements, new thermostats, and a bond that will actually pass an inspection.

Endless hot water — but only if your gas line and venting can carry it. We size on fixture count and inlet temperature before quoting.

For heaters in a closet or a finished basement with no chimney. PVC vent run pitched right and the condensate handled properly.

A closed system needs somewhere for thermal expansion to go. Expansion tanks, pressure reducing valves and thermostatic mixing valves.

Oklahoma water is hard. Flushing the sediment and pulling a spent anode rod is what gets a tank past year eight.
The most recent heater we set — capacity, fuel, and how the gas and water got run. New one most weeks, shot before the tools went back in the van.

Shot close on the parts that decide whether a heater lasts eight years or eighteen.







The two ways a water heater job goes wrong are the wrong size and lazy pipe.
Tankless is specified off your real fixtures and winter inlet temperature. Undersized units are the complaint we hear most.
Every connection stays serviceable. The next person to touch it won't need a torch.
Common tanks ride with us, so most replacements happen the same day you call.
Gas and venting work gets inspected. That paperwork matters when you go to sell the house.
Send the capacity off the label, whether it's gas or electric, and where it sits in the house. That's usually enough for a firm price without anyone coming out.
Call before nine and there's a good chance you're showering tonight. Text a photo of the label and we'll price it on the spot.
