Why flush a water heater?

Hard water in Northwest Montana drops minerals in the bottom of a tank. The burner (or element) works through that layer, the tank rumbles, hot water runs short, and parts wear out early. A flush clears it out, and an inspection catches small problems before they become a no-hot-water call on a holiday weekend.

What's different about our flush

  • One flat rate for the flush and inspection
  • On electric tanks we go further: new heating elements and the tank vacuumed out, not just drained
  • You deal with the owner — Reeve answers the phone, 24/7

Water heater repair

No hot water, lukewarm showers, a pilot that won't stay lit, a dripping T&P valve, a tripped breaker, a rotten-egg smell at the tank, or a tankless throwing codes — we service what you have. Gas, electric, tank and tankless.

Gas tanks. No hot water, a pilot that will not stay lit, rumbling from sediment, a T&P valve that drips, or a rotten-egg smell at the tank. Service covers the burner, thermocouple or hot-surface igniter, gas valve, venting, temperature and pressure relief, anode rod, and a flush.

Electric tanks. Tripped breaker, one element dead (lukewarm, not cold), a failed thermostat, or a leak at a fitting. We test both elements and both thermostats so the easy part isn't fixed while the real problem stays behind.

Water pooling at the bottom of the tank is urgent: shut the water and the power or gas off if you can do it safely, and call (406) 260-2952.

Tankless water heater service. Tankless units heat on demand. They last when they get descaled. They fail early when hard water is ignored. A typical service: read the error code instead of guessing; clean the inlet screen and flush/descale the heat exchanger; check ignition, flame, and the gas or electric supply; confirm venting and condensate drain on condensing units; verify flow — scale is the usual reason output drops. Cold Flathead incoming water and hard well or city water are a bad mix for a neglected tankless. If you have not descaled in a couple of years, that is the first thing we look at.

  • Friendly , professional service. Not only did they fix my gas fireplace but they took the extra time to adjust all the setting so that the unit was functioning properly and safely! And all on a Saturday!

What's included on a gas water heater?

A full flush and an inspection of all components. New heating elements apply to electric tanks only. Exclusions apply. Contact us for more info.

Why is my water only lukewarm?

Dip tubes fail, elements burn out one at a time, thermostats drift, and mixing valves stick. On tankless units, scale from hard water cuts output. Lukewarm water is one of the most common service calls we run in the Flathead.

Why is my tank popping or rumbling?

Sediment. Hard water in Northwest Montana drops minerals in the bottom of the tank. The burner boils water under that layer and the tank sounds like popcorn. Flushing and anode-rod service slow it down. Don't ignore it through another winter.

Why do I have no hot water?

On a tank unit, common causes are a tripped breaker, failed heating element, bad gas valve or igniter, a failed thermocouple, or a tank that’s filled with sediment. On tankless, it’s often ignition, a scale-clogged heat exchanger, or a code on the display. We'll tell you what failed and what it takes to fix.

My water heater is leaking. What now?

A leak at a fitting or T&P valve can often be repaired. Water pooling at the bottom of the tank is urgent: shut the water and the power or gas off if you can do it safely, and call. Standing water around a gas water heater is not a wait-until-Monday problem.

Tank or tankless — which is better?

Tanks are simpler and usually cheaper to keep running. Tankless units heat on demand and can last longer if they’re descaled. Hard water is hard on both, tankless especially. We service tank and tankless, gas and electric.

How often should a water heater be flushed or maintained?

Flush a tank yearly if you can, more often on hard water. Anode rods are often inspected every two to three years. Tankless units need descaling on a schedule or they lose flow and throw codes. Maintenance is cheaper than an emergency no-hot-water call on a holiday weekend.

How long do water heaters last?

Tank units commonly last about 8–12 years here; hard water shortens that. Tankless can go longer with descaling.
