Nine months of steady demand on your water heater
Water heaters in Polk County run October through June, nine months of the year. On winter nights averaging 35°F, the water coming into the tank is cold, and the heating element and thermostat spend longer getting it up to temperature. Over time that shows up as water that takes longer to heat or never quite reaches the setting you want.
Power is part of it too. In Oregon, 20% of households went at least 24 hours without power in 2024, and the county has recorded damaging wind events over the past ten years. A gas water heater with a standing pilot keeps running through an outage. One with electronic ignition will not relight on its own, and you will find cold water until someone resets it.

A new water heater would cut about $390 a year off hot water for a typical Oregon home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself, rusted through from the inside and starting to fail. Sediment builds up at the bottom of the tank over years and corrodes the steel until it gives way, and once that happens the tank cannot be patched. Water can also come from a loose drain valve or a fitting where a pipe connects, and those can sometimes be tightened or replaced. A contractor can tell you which one you have by drying the area and checking where the water shows up first.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small part that sits in the pilot flame and tells the gas valve it's safe to stay open. If it can't sense the flame anymore, it shuts the gas off even though the pilot is lit, and the flame goes out again soon after you release the knob. A dirty pilot orifice or a draft blowing on the flame can also cause it, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is usually cleared with a descaling flush, especially in homes with hard water. Igniters, flow sensors, and gas valves can also fail on their own and get replaced without needing a new unit. A contractor can run the diagnostic codes on the unit to find out which part is causing the problem.
