Water heater replacement in Littleton: what's different
Because a Littleton address can be inside the city or in unincorporated Jefferson, Arapahoe or Douglas County, the plumber checks the exact jurisdiction before pulling a water heater permit. Your property tax bill tells you which.
The large 1970s–80s neighborhoods west of downtown are well past their original heaters, and many have finished basements around the utility room. Replacement updates venting and gas connections and often adds an expansion tank.
- Water and sewer in Littleton

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.

Repair or replace your water heater?
