Water Heater Repair in Thornton, CO

What happens when you call

You'll be connected with an independent plumber who works in Thornton. Expect questions about the fuel type, age and symptoms. On site, the plumber checks power or gas, tests elements and thermostats or the burner and ignition, inspects the relief and drain valves, and drains some water to see how much scale and sediment the tank holds, which matters a lot in Thornton. You get an explanation and a recommendation before work starts.

Cost factors

• Scale. Hard water often means a crusted element, a flush or descaling on top of the main repair.
• The part. Elements and thermocouples are minor; gas valves and burners cost more.
• Heater type. Tankless units need descaling more often in hard water.
• Replacement. A failed tank means a new heater and a city permit.

Local conditions in Thornton

Thornton's water is hard. The city's water quality report gives hardness from roughly 152 to 356 mg/L, averaging about 230 mg/L, or around 13.5 grains per gallon, and says its treatment plants do not remove hardness. That mineral load coats electric elements, piles sediment on gas burners and shortens tank life if a heater is never flushed. Rumbling, popping, hot water that runs out early and elements that burn out repeatedly are all classic signs. The city's supply is mountain snowmelt from the South Platte basin, stored in reservoirs including Standley Lake, and it is disinfected with chloramine. Regular flushing, or a water softener, can slow that buildup.

Most Thornton homes date from 1980 on: census estimates put the median build year at 1997, with about 21.9% built before 1980, mostly in the older south end. So many heaters are originals or first replacements now in their second decade.

The City of Thornton Building Inspection Division requires a permit to install or replace a water heater, and for plumbing modifications and gas lines. Gas comes from Xcel Energy for most of the city, though the city says some areas are served differently, so check your bill. If you smell gas, leave the house first, then call 911 and your gas utility from outside; Xcel's gas emergency line is 1-800-895-2999.

Before the plumber arrives

• Shut off the heater and its cold supply if leaking
• Note how long it has been since the tank was flushed
• Find the label date and size
• Clear space around the heater
