Why Water Heater Maintenance Super Matters in MT
Missoula’s and western Montana’s mineral rich water supply speeds up sediment buildup inside tanked water heaters faster than in most areas throughout the USA. Hard water shortens equipment life, raises energy bills, and damages the water heater.
Water heaters account for roughly 25% of a home’s total energy consumption. A neglected unit burns more fuel doing the same job.
The 10 Best Maintenance Moves
- Flush the tank annually.
Sediment collects at the bottom and forces the heating element to work harder. Connect a hose to the drain valve, flush until the water runs clear every 12 months. - Inspect the anode rod every 2 to 3 years.
The anode rod (a sacrificial metal rod inside the tank) attracts corrosive minerals before they eat your tank lining. Replace it when it’s less than half its original thickness. - Test the T&P relief valve yearly.
The temperature and pressure relief valve is your tank’s safety release. Lift the lever briefly and confirm water discharges. - Set the thermostat to 120°F.
Most tanks are set to 140°F. Dropping to 120°F reduces standby heat loss, lowers scalding risk, and cuts energy use. - Insulate the first few feet of hot and cold supply pipes.
Pipe insulation reduces heat loss between the tank and your fixtures. Costs only a couple bucks at the hardware store.
Tips 1 through 5 are DIY-friendly and they cost almost nothing and can add years to your water heater’s life.
- Check for corrosion around fittings and connections.
Rust-colored staining near inlet pipes or the base of the tank means corrosion. Catch it early enough and you’re just looking at a fitting replacement. - Keep the area around the unit clear.
Gas water heaters require a good amount of combustion airflow. Cramped utility closets restrict that airflow, causing incomplete combustion and more wear and tear. - Know your unit’s age.
The serial number on most tanks encodes the manufacture date. Tanked units typically last 8 to 12 years. Tankless units from brands like Navien can reach 20 years with proper care. If your unit is past its window, budget for replacement in preparation. - Consider a water softener if you haven’t already.
Softened water reduces mineral stress on every water-using appliance in your home. This single upgrade measurably extends heater life not to mention the other benefits. - Schedule an inspection every 1 to 2 years.
DIY maintenance handles surface level things. A licensed plumber catches what you can’t see. Things like hairline cracks, gas valve issues, and pressure irregularities.

A standard maintenance visit from a licensed plumber typically runs between $80 and $200 depending on the work being done.
