Plumbing issues worth knowing about
Sewer backups and the line you own
The City is clear about this: the sewer service line from your house to the main belongs to the property owner, including the part under the street. When a backup happens, City crews check the main. If the blockage is in your line, you need a contractor. The City lists tree roots, cracked pipe and grease as common causes.

Rusty water or weak pressure in older homes
Galvanized steel supply pipe was common in houses built before the 1960s. It corrodes from the inside, so pressure drops slowly and water can run brown after it sits. If one faucet is weak, it's usually the fixture. If the whole house is, ask about the supply pipe.

Water heater replacement needs a City permit
Colorado treats a water heater swap as plumbing work. It needs a licensed plumber, a permit and an inspection. In 80120 the permit comes from the City of Littleton. Ask whoever you hire to pull it.

Questions from Central Littleton homeowners
Is my 80120 address inside Littleton city limits?
Yes. 80120 is the only Littleton ZIP code entirely within the city. Most other Littleton ZIP codes are only partly in the city, and some aren't in it at all.
My sewer is backing up. Do I call the City or a plumber?
Call the City first so crews can check the main: 303-795-3959 on weekdays, 303-794-1551 after hours. If the main is clear, the blockage is in your service line and you'll need a contractor.
Who supplies my water?
Denver Water. Littleton sold its water system to Denver Water in the early 1970s, and Denver Water has supplied every city address since. Its customer line is 303-893-2444.
