Common water heater problems
- No hot water at all: pilot out, a failed thermocouple or igniter on gas units, a tripped breaker or burned-out element on electric units
- Not enough hot water: a failed lower element, sediment taking up space, a broken dip tube, or a heater that's simply too small for the household
- Water around the base: could be a fitting or the relief valve, or the tank itself
- Rusty or smelly hot water: often a worn anode rod or corrosion inside the tank
- Relief valve dripping or discharging: a sign of too much pressure or temperature. Have it checked; don't cap it.
Hard water and your heater
Hard water is common in the Pahrump Valley. In a tank heater, minerals drop out as the water heats and collect on the bottom or around the elements. That build-up insulates the water from the burner, wastes energy, makes noise and stresses the tank. Periodic flushing and checking the anode rod are inexpensive maintenance tasks a plumber can do. Some homeowners add a water softener to slow the scaling. See hard water & softeners.
Replacement options
Tank (storage) heaters
Gas, propane or electric. Simple, familiar and usually the most direct swap for the unit you have now. Size is picked by household demand.
Tankless (on-demand)
Heats water as it flows. Takes up less space and doesn't run out during back-to-back showers, but it may need gas line, venting or electrical upgrades, and descaling in hard water.
Heat-pump water heaters are another electric option. Many Pahrump homes run on propane rather than natural gas, so tell the plumber your fuel type when you call.
What to have ready when you call
- Fuel type (natural gas, propane or electric)
- The size and age, from the label on the side of the tank
- Where it's located (garage, closet, attic, exterior closet)
- What you're seeing: no hot water, leaking, noises, discolored water
Water heater FAQ
Should I repair or replace my water heater?
If the tank itself is leaking, it needs to be replaced. Tanks can't be patched. Problems with a thermocouple, gas valve, heating element, thermostat or igniter are often repairable. Age, the condition of the tank and how often it has needed service all factor into the decision. Ask the plumber to explain both options.
Why does my water heater make popping or rumbling noises?
That's usually sediment. Minerals from hard water settle at the bottom of the tank, and water trapped under the layer boils and pops. It makes the heater work harder. Flushing may help if it hasn't gone too far.
Is tankless worth it in Pahrump?
It can be, but it isn't automatic. Hard water scales tankless heat exchangers, so a softener or regular descaling is usually recommended. Gas tankless units may also need a larger gas line and new venting. A plumber can tell you whether your home is set up for it.
Do I need a permit to replace a water heater?
Many jurisdictions require one, because gas connections, venting, and the temperature and pressure relief valve are safety items. Ask your plumber whether a permit is required for your address and who will pull it.
