Most Arvada water heaters that stop heating or start dripping need one part, such as an element, thermostat, thermocouple or valve, and a plumber can often replace it in a single visit. A tank leaking through its own shell has to be replaced. Call the number on this page to be connected with a local plumber in Arvada.

Does Arvada require a permit just to swap a water heater?
Yes. The City of Arvada asks for a permit and an inspection before a water heater is replaced or installed, and it files domestic water heaters under its Residential Plumbing permit. The city also counts a change in burner input of 5% or more as a modification, so trading an old tank for a higher-input model is not a simple like-for-like swap on paper. Contractors holding an active Arvada license apply through the online Arvada Permits system, while homeowners doing their own work apply in person at City Hall on Ralston Road. Ask the plumber whether your particular repair falls under that rule before the work starts.
Is Arvada water hard on tanks?
Less than in many metro cities. Arvada treats its own water at the Ralston and Arvada plants, and its annual report puts average total hardness at about 43 ppm from Ralston and about 65 ppm from the Arvada plant, both toward the soft end. That means less crust on electric elements and less sediment settling over a gas burner than in harder-water suburbs. Tanks still gather some grit over the years, so a flush during a repair visit is worth asking about, especially on a heater that rumbles as it fires. A few pockets inside city limits are served by other districts, including Ralston Valley, Consolidated Mutual and Denver Water, so check your bill to know which report applies.
My house was built in the 1970s. Repair or replace?
Arvada's housing leans older: census estimates put the median build year at 1979, with about 52.5% of homes built before 1980. Nearly all of those houses are on a replacement heater by now, so what matters is the tank's own age on the label. A heater under roughly ten years old with a failed thermostat, element, thermocouple or gas valve is usually worth fixing. An older tank that leaks from the shell or shows rust at the top fittings is normally better replaced. Older basements can also have cramped flue connectors or stiff shutoff valves that are worth correcting on the same visit.
A note on gas safety in Arvada
Xcel Energy supplies natural gas in Arvada. If you notice a rotten-egg smell near the heater, don't relight the pilot or touch switches. Get everyone out of the house first, then call 911 and Xcel Energy at 1-800-895-2999 from outside. A plumber can take over once the utility has made the area safe.
