3 Quick Checks Before You Call
Sometimes it's not the water heater — run through these first. If none of them resolve it, call us.
Gas Unit: Check the Pilot Light
Look at the small window near the bottom of the tank. If the pilot flame is out, follow the relight instructions on the unit label. If it won't stay lit after three attempts, the thermocouple has likely failed — call us.
Electric Unit: Check the Breaker
Find your electrical panel and look for the water heater breaker (usually 30-amp double-pole). If it's tripped, reset it once. If it trips again immediately, the heating element has likely shorted — call us.
Check the Unit Age
Look for the serial number sticker on the side of the tank. The manufacture date is encoded in the serial number — first two digits are typically the year. In Knox County's moderately hard water, anything over 10 years old is at or past end of life. If it's old and failing, replacement now beats an emergency call after it floods your utility room.
Checked all three and still no hot water? That's what we're here for.
Call (888) 433-5685 — Same Day ServiceWhy We Stock Units for Same-Day Replacement
Most plumbers don't carry water heaters on the truck. They schedule, order, and come back in 2–3 days. We stock common 40 and 50-gallon gas and electric units because no hot water is an emergency — not a 3-day inconvenience.
Knoxville's average January low is 29°F. Cold showers in January are not an option.
Families can't function without hot water. Dishes, laundry, showers — it all stops.
A leaking tank can do thousands in water damage if left unaddressed. Speed matters.
If Your Water Heater Is Leaking Right Now
Turn off the cold water supply. The shutoff valve is on the cold water pipe entering the top of the tank. Turn it clockwise to close.
Turn off the heat source. For gas: turn the control knob to "pilot" or "off." For electric: flip the breaker off at the panel.
Call us immediately. Don't wait. A leaking tank is a failing tank — the question is whether it floods before you replace it or after.
Emergency Service FAQ
What should I do if I have no hot water in Knoxville?
First, do a quick 3-step check: (1) For gas units — check if the pilot light is on. (2) For electric units — check if the breaker has tripped. (3) Check the age of your unit — if it's over 10 years old in Knox County's moderately hard water, it's likely at or past end of life. If those checks don't resolve it, call us. We can often be there the same day.
How fast can you get to Knoxville for an emergency water heater?
For calls received before noon on weekdays, same-day service is available in most Knox County locations. We stock common 40 and 50-gallon gas and electric units — there's no waiting for a parts order in most cases.
Can you replace my water heater the same day it fails?
Yes, in most cases. Standard 40 and 50-gallon gas and electric units are in our inventory. If you call us in the morning, we can often have a new unit installed and running the same day. Unusual sizes or specialty units may require a short lead time.
Is it safe to use my water heater if it's leaking?
No. Turn off the water supply to the unit immediately (the shutoff valve is on the cold water inlet pipe at the top of the tank) and turn off the gas or breaker to the unit. A leaking tank is close to failure and can cause significant water damage. Call us — this is a same-day situation.
