Common water heater install & repair problems homeowners see
No hot water, or it runs out fast
On an electric heater this is usually a failed upper or lower element or thermostat. On a gas heater it is often the thermocouple, gas valve or a pilot that will not stay lit. Sediment in the bottom of the tank also steals capacity, which is why a 50-gallon heater can start acting like a 30.
Rusty or discolored hot water
Brown or metallic-tasting hot water usually means the anode rod is spent and the tank's glass lining is corroding. Once the tank itself is rusting, replacement is the honest answer.
Popping, rumbling or crackling
These sounds can indicate sediment or mineral buildup in the tank. An inspection can determine whether maintenance, repair or replacement is appropriate.
Water around the base
A weeping temperature and pressure relief valve or drain valve can be replaced. Water seeping from the seam of the tank cannot — that heater needs to come out before it lets go.
When to call a licensed plumber
- Any water on the floor around the heater, or a heater installed in an attic or upstairs closet
- Gas smell, soot, scorch marks around the burner, or a pilot that will not stay lit
- The temperature and pressure relief valve is discharging
- The heater is repeatedly failing or showing signs of tank deterioration
- You need a permit or code upgrades handled as part of a replacement
Your water heater install & repair options
Repair
Elements, thermostats, thermocouples, gas valves, relief valves, drain valves, expansion tanks and flex connectors. If a repair genuinely buys you years, we will say so.
Tank replacement
Gas or electric, sized to how your household actually uses hot water, with new connectors, shutoff, drain pan and code-required expansion control.
Tankless conversion
When gas supply, venting and location work out, a tankless unit ends the capacity problem entirely. See our tankless water heater page for what that conversion involves.
Maintenance
Flushing, anode rod replacement and combustion checks to get the lifespan you paid for.

Frequently asked
How much does a new water heater cost in NWA?
Water-heater pricing depends on the unit, fuel type, venting, access and code upgrades required. Every installation includes a written, upfront quote before work begins.
Is my water heater worth repairing?
If it's under 8 years old and the tank itself isn't leaking, usually yes. We'll tell you the truth either way.
How long does a water heater replacement take?
A straightforward tank-for-tank swap is typically a few hours. Fuel changes, relocations, venting corrections or code upgrades add time, and we tell you the scope before we start.
Do you pull permits for water heater installs?
Yes, where the city requires one. That keeps the installation documented and your manufacturer warranty intact.
