A Larkspur water heater that stops heating or starts leaking usually needs one part replaced, such as an element, thermostat, thermocouple or valve, and a plumber can often do it on one visit. A leak from the tank shell means replacement. Call the number on this page to be connected with a local plumber in Larkspur.

What happens when you call
You'll be connected with an independent plumber who serves Larkspur and southern Douglas County. They will ask about the heater's fuel, age and symptoms so they can bring the likely parts. At the house, the plumber checks power or gas, tests elements and thermostats or the burner and pilot, looks at the relief and drain valves and checks the fittings for leaks or corrosion. You'll learn what failed and whether a repair is worthwhile before work starts.
What affects the cost
- The failed part. Elements and thermocouples are minor; a gas valve costs more.
- Travel. Larkspur sits about 11 miles south of Castle Rock, which can factor into a visit.
- Sediment. Well-supplied tanks may need flushing before new parts go in.
- Replacement. A failed tank means a new heater, permitted through the Town.
Local conditions in Larkspur
Larkspur is a small town along I-25 in the East Plum Creek valley, best known as home of the summer Colorado Renaissance Festival. Inside town limits, the Town's Public Works Department runs water and wastewater, with the water system operated under contract by Semocor. Drinking water comes from three Denver Basin aquifer wells in the Denver and Arapahoe aquifers rather than surface water. Groundwater can leave more mineral deposits in a tank than mountain snowmelt, though no hardness figure was available, so a plumber judges sediment by draining a few gallons. Areas of the 80118 ZIP outside town limits are not on these Town systems.
Inside town limits, the Town of Larkspur, not Douglas County, handles building permits: the Town Building Department on Spruce Mountain Road processes applications and SAFEbuilt does the inspections. The Town's page does not mention plumbing permits by name, so ask the plumber or the Building Department whether a water heater replacement needs one.
Water emergencies inside town go to Town Hall during business hours and to Semocor after hours. Gas comes from Black Hills Energy; if you smell gas, leave the house first, then call 911 and Black Hills Energy from outside using the emergency number on your gas bill.
Before the plumber arrives
- Turn off power or gas and the cold supply if it is leaking
