FAQs
What does “same-day service” for a tank water heater mean in Knoxville?
If you call us before 12:00 p.m. Monday–Saturday, we guarantee that a licensed plumber will arrive, diagnose, and either repair or replace your standard tank-style water heater before the end of the business day. We stock the most common 40-, 50-, and 55-gallon natural-gas and electric models on our trucks or in our nearby warehouse so we can complete the job without a return visit.
Can you replace my water heater the same day if the tank is leaking?
Yes. A leaking tank cannot be repaired, so we carry ready-to-install Rheem, Bradford White, and A.O. Smith replacement units. Once onsite, our technician will shut off water and power/gas, drain and remove the failed heater, set the new unit, reconnect water, gas or electrical, and relight or power up the system—usually in 2–4 hours. All work meets the 2021 International Plumbing Code and local Knoxville/Knox County amendments.
Do I need a permit or inspection to replace a water heater in Knoxville?
Both the City of Knoxville and Knox County require a mechanical/plumbing permit when a water heater is replaced, along with a final inspection. As a licensed, bonded, and insured contractor, we pull the permit for you, schedule the inspection, and leave the approval tag onsite. There is no extra trip charge for the inspection because we coordinate it while we are still in the area.
What does a same-day tank water heater installation typically cost?
Prices vary by capacity, fuel type, and efficiency rating, but most standard replacements fall between $1,200 and $2,100, which includes the new heater, supply lines, expansion tank, gas flex or whip, haul-away of the old unit, permit fees, and tax. You’ll receive a firm, written quote before any work starts, and we offer 0% financing for 12 months to qualified homeowners.
Which brands and sizes of tank water heaters do you service or install?
We service and install all major residential brands—including Rheem, A.O. Smith, Bradford White, State, Whirlpool, and GE—in capacities from 20 to 120 gallons. Our warehouse keeps the most common 40- and 50-gallon electric and natural-gas units in stock, but we can special-order high-efficiency or power-vent models and still have them ready the next business day.
How can I extend the life of my new water heater in East Tennessee?
Knoxville’s water is moderately hard, so mineral buildup is the number-one enemy of tank longevity. We recommend draining and flushing the tank every 12 months, checking the anode rod every 3–5 years, and keeping the thermostat at 120 °F to reduce scald risk and energy use. Signing up for our annual maintenance plan ensures those tasks are handled automatically, and it adds an extra year of labor warranty on any heater we install.
