Water Heater Replacement in Westminster, CO

In Westminster, a water heater should be replaced when the tank leaks, the water comes out rusty, or an older unit keeps needing repairs. The city requires a building permit to install or replace water heaters, tank or tankless. Call the number on this page to be connected with a local plumber in Westminster.

Westminster draws all of its water from Standley Lake, filled by Clear Creek snowmelt, and treats it at the Semper and Northwest plants. The city reports hardness of 112 to 149 ppm, about 7 to 9 grains per gallon, which is moderately hard. That's enough for sediment to build up in a tank over the years. Homes here have a median year built of 1987, so plenty of houses have already gone through a heater or two.

What to do right now

If water is leaking, close the cold supply valve on top of the heater.
Turn the gas control to off, or switch off the breaker for an electric unit.
Run a hose from the drain valve to a floor drain or outside if the tank needs emptying, and keep clear of hot water.
Write down the size, fuel type and age from the label.
If you smell gas at any point, leave the house, then call 911 and Xcel Energy at 1-800-895-2999 from outside.
Call for a replacement quote and ask that it include the city permit.

The City of Westminster Building Division permit and haul-away

The Building Division, at 4800 W 92nd Avenue, takes permit applications through eTRAKiT and lists tankless units by name alongside standard tanks. When you compare quotes, check that each one names the permit, the inspection and removal of the old heater, and ask how the plumber handles code corrections the inspector might flag. A heater that sits over a finished room in a split-level or basement usually needs a drain pan, which is easier to plan for up front than to add after the inspection.

Water Heater Replacement questions in Westminster

Does a water heater replacement here need a permit, and who issues it?

Yes. The City of Westminster Building Division requires a permit to install or replace a water heater, including tankless models. Applications go through eTRAKiT.

How will the local water affect a new tank?

Westminster reports 112 to 149 ppm hardness, about 7 to 9 grains per gallon. That's moderately hard, so expect some sediment and plan on flushing the tank yearly.

Will the new heater need a thermal expansion tank?

Many installs do. When a home's plumbing can't push expanding hot water back into the main, an expansion tank absorbs the pressure. The plumber will check your system and local inspection requirements.

What happens to the old water heater?

Most installers haul the old tank away as part of the job. Ask that removal be written into the quote so there are no surprises.
