What Our Customers Say

trust
“Installed a tankless water heater and the system works great. Honest about options.”
Shut off power or gas and close the cold‑water valve immediately if a water heater is leaking from the bottom, then call a licensed plumber to assess and, if the tank has failed, replace it. The most common cause is internal tank corrosion opening a seam near the base; less often it’s a loose drain valve or heavy condensation. A bottom leak on a tank model usually points to a compromised tank that isn’t safe to repair, while valve or connection leaks can often be fixed. I’ve also found leaks that looked like they came from the base but were actually from a T&P discharge or top fitting running down the jacket. Our Knoxville-area team often handles urgent water heater leaks the same day.
Take these immediate steps:
- Turn off the breaker or set gas control to off.
- Close the cold‑water shutoff on top of the tank.
- Avoid standing water; it can be scalding or electrified.
- If safe, snap a photo of the label for model/serial info.
If leaking accelerates or you smell burning, leave the area and call for emergency service.

Water heater replacement cost with The Plumbing Authority is confirmed after an on-site assessment, because the appliance selected, any code-required work, and your home’s layout determine the total. Most of the cost typically sits in the new heater plus the professional, code-compliant installation that follows manufacturer specifications. We routinely perform replacements across the Knoxville area, so we size and vent systems for East Tennessee water and seasonal demands. Financing options are available on product pages, and when inventory allows we often complete replacement the same day.
What most affects price:
- Type of system: standard tank, tankless, hybrid heat pump, or indirect
- Capacity and performance goals: gallon size or tankless flow rate
- Fuel and venting/electrical needs: gas line, combustion air, power, or flue changes
- Location and access: tight spaces, drain pan/expansion needs, permits, and disposal
Ask for an on-site estimate to confirm scope, code needs, and the best repair-or-replace path.
