Well Pump Repair in Longmont, CO

Where does Longmont's water come from?

Longmont, founded in 1871 by the Chicago-Colorado Colony, runs its own city water utility. It draws on North and South St. Vrain Creeks, stored in Ralph Price Reservoir, and on Colorado-Big Thompson Project water from the Colorado and Fraser rivers by way of Lake Granby, Grand Lake and Carter Lake. The Wade Gaddis and Nelson Flanders plants treat it, and it's disinfected with chlorine. The city reports soft water, typically 1 to 2 grains per gallon. Every customer on that system receives pressurized water through a meter, so there's no household pump to fail.

If it's not a pump, what is it?

For a Longmont house on city water, a pressure drop usually traces to a failing pressure regulator, a partly closed or worn main valve, a leak on the service piping, or clogged aerators and cartridges. Because the water is soft, heavy mineral scale is less likely to be the cause than in harder-water towns. Longmont's median home was built in 1991, with about 37% built before 1980; older houses near Main Street can have aging valves and piping, while newer ones more often have regulator or fixture problems. If you live outside city service and have a wellhead and pressure tank, then a pump, switch or tank may well be the issue.

Do I need a permit for this kind of repair?

Longmont requires a permit for any change to electrical, gas, mechanical or plumbing systems, issued by Building Services at the Development Services Center, 385 Kimbark Street, (303) 651-8332. A simple repair like an aerator or cartridge swap usually doesn't change the system, but replacing piping or a regulator may. If your work involves a backflow assembly, new or replacement assemblies must be RPZ type unless the city approves otherwise, need a miscellaneous permit, and annual tests go through the city's SwiftComply portal.

A local note

Longmont Water Utilities answers at (303) 651-8416 from 8 a.m. to 5 p.m. on weekdays; after hours, the city directs callers to Longmont Public Safety Dispatch.

When you call, mention whether the house is on city water, roughly when it was built and whether the drop affects hot and cold equally. A loss on the hot side alone usually points to the water heater or its valves rather than the supply.
