When a pipe bursts in a Littleton home, close the main valve and turn off power near any standing water. A plumber can cut out the ruptured section, splice in new pipe and inspect nearby lines. Call the number on this page to be connected with a local plumber in Littleton.

Who do I call about the water line outside?
The City of Littleton says all city residents get water from Denver Water; the city itself doesn't run a water utility. Denver Water says the property owner owns the service line, including the stop and waste valve, and the meter pit and meter, while Denver Water maintains the mains. In practice, that makes most breaks between the street and the house, as well as everything indoors, a private repair. If water is boiling up in the street, call Denver Water at 303-893-2444 during business hours or 303-628-6801 after hours so it can check the main.
Littleton ZIP codes reach well beyond city limits into places like Columbine, Ken Caryl and Highlands Ranch, which are served by other districts. If your address is outside the city, your water provider is different.
Why do older Littleton homes crack pipes in a freeze?
Much of Littleton went up during the 1950s and 1960s boom, and houses from that era have often been replumbed piece by piece. Galvanized sections, copper repairs and newer plastic can all meet in one basement, and the transitions are weak points when a line freezes. Supply lines in crawl spaces, exterior walls and under additions are the usual casualties. When a plumber repairs a break in an older house, expect a look at the pipe on either side, since splicing into corroded pipe rarely lasts.
Is a permit needed, and who issues it?
Littleton requires a city permit to install, alter, repair or replace any plumbing system within city jurisdiction, so a burst pipe repair inside city limits generally goes through the Permit Center (303-795-3751). Homeowners doing their own single-trade work sign a Homeowner Affidavit. Addresses with a Littleton mailing address outside city limits get permits from Arapahoe, Jefferson or Douglas County instead; the city's District Map Tool shows which applies.
Sewer is separate
A burst supply pipe can send water down floor drains, but sewer is a different system here: the City of Littleton handles sewer service for most residents, with after-hours sewer emergencies at 303-794-1551. If the floor drain backs up while the supply pipe is leaking, mention both problems when you call so the plumber comes prepared for each, and keep people and pets away from the wet area until power to it is off.
