A failed tank is an emergency
A tank that leaks through the wall cannot be patched. The steel has corroded through, and the leak will grow. Water on the floor can ruin drywall and flooring in hours, so the first step is to stop the water and the fuel, and the second is a replacement.
We take emergency replacement calls 24/7, including nights and weekends, and book same-day installation when available. The plumber arrives, confirms the failure and quotes the replacement before removing the old unit.
- Close the cold water valve on the pipe at the top of the tank.
- Turn the gas control to off or switch the breaker off.
- Open a hot faucet in the house to let the lines drain.
- Mop the floor and move belongings away from the water.
- Photograph the unit and the damage, including the serial label.
Repair, replace or switch type
| Situation | Usually best | Why |
|---|---|---|
| Tank leaks through the wall | Replace | A corroded tank cannot be patched |
| Tank over about 10 years old with a failing part | Replace | The next failure is likely soon |
| Newer tank, failed element or thermocouple | Repair | The tank is sound |
| Frequent hot water shortage | Larger tank or tankless | Demand outgrew the unit |
| Need to cut space or gas use | Tankless or hybrid | Wall mount or heat pump design |
If a repair is the cheaper answer, see water heater repair. If you are planning ahead and the heater still works, water heater installation covers the planned route.
Choosing the right replacement
Standard tank
The most common type. Size by household. A 40 gallon tank suits one or two people, 50 gallons suits a typical family, and larger homes may need 75 gallons.
Tankless
Heats water on demand and takes less room. It needs a gas line and venting sized for the unit, and it needs a flush in hard water. See tankless service.
Hybrid heat pump
Uses a heat pump to cut electric use. It needs space for airflow and a drain for condensate.
Like for like
Swapping a gas tank for a gas tank in the same spot is the fastest route, often the same visit.
What a replacement visit includes
Shut off and drain
The plumber closes water and fuel and drains the old tank.
Remove and set the new unit
The old tank is disconnected and hauled off. The new one goes on a drain pan if the location calls for it.
Connect, brace, test
Water, gas or power, venting, relief valve and drain piping are connected. The unit is braced, filled, checked for leaks and brought up to temperature.
California requires residential water heaters to be braced against earthquake movement, and the code sets standards for relief valve piping and venting. Permit rules vary by city, so ask the Sanger Building Division whether your replacement needs one. We never guess at permit rules.
Local conditionsWater in Sanger and what it does to a new heater
The city's 2024 water quality report lists Sanger hardness averaging 145.5 ppm. A heater in hard water collects scale, so a yearly flush helps a tank last. Some homeowners add a water softener to protect heaters and fixtures, which our water softener and filtration page covers.
If your old tank died young, check for a heavily scaled interior, a worn anode rod and high water pressure. A pressure check and an expansion tank, where needed, protect the new unit.
What affects the price of water heater replacement
Replacement pricing depends on the unit and the site. We give a clear price before work starts, including removal of the old tank.
Homeowner insurance often covers damage from a burst tank but not the tank. Keep the old unit's label and photos for a claim. Want your real number? Call (855) 575-2890.

Water heater replacement questions
Yes. Our dispatch line answers 24/7, and a licensed plumber is booked for same-day replacement when available.
A like-for-like tank swap often takes a few hours. Changing type, location or venting takes longer.
It depends on household size and peak use. A plumber checks your hot water habits and recommends a size.
Yes, removal of the old unit is part of the visit.
