What shapes water heater trouble in Star
Problems in a nearly new house
About 22% of Star homes were built in 2020 or later, and the median home dates from 2011. In a house this new, water heater calls are often about setup rather than wear: a relief valve that drips, a pilot or igniter that won't stay lit, or water that's too hot or not hot enough.
A dripping relief valve can mean the pressure in the tank climbs as water heats. A plumber can check the valve, the water pressure and whether an expansion tank is needed.
Water from deep wells
Star Sewer & Water District's 2025 report says its main production well, Well Site No. 7, draws from an aquifer about 700 feet down, backed by four supplemental wells deeper than 300 feet. The district is adding two more wells. Not every Star address is in the district, so check your water bill.
Boise-area cold
NOAA's Boise Airport station averages about 108 nights a year at or below freezing and January lows near 26°F. About 82% of Star homes heat with gas, and gas water heaters work hardest on those mornings.

Why is the relief valve on my new water heater dripping?
It may be a faulty valve, but it often means pressure builds as the water heats. A plumber can check the valve, the household water pressure and whether an expansion tank is needed.
Where does Star's water come from?
Star Sewer & Water District uses deep groundwater wells, with its main well drawing from about 700 feet down.
Is my new water heater under warranty?
Probably, if it's only a few years old. Photograph the label with the model and serial number so the plumber can check.
