Plumbing issues worth knowing about
Polybutylene in homes built from 1978 to mid-1995
Polybutylene supply pipe was installed nationally from 1978 to mid-1995, and a large settlement covered failures in that window. A big share of homes here were built in those years. Polybutylene is gray, flexible and often stamped PB. If you see it near the water heater or main shutoff, have it looked at before it leaks.

Sewer laterals and backups
The line from your house to the district's sewer main is generally the owner's to maintain. In 40- and 50-year-old homes, roots and grease are the usual culprits. If more than one drain backs up at once, the problem is in that line, not a single fixture.

Water heaters and the county permit
Colorado requires a licensed plumber, a permit and an inspection for water heater replacement. Jefferson County lists water heaters as a plumbing permit. Ask whoever you hire to pull it.

Questions from Columbine & Southwest Littleton homeowners
Is Columbine part of Littleton?
Mostly not. Columbine is an unincorporated community governed by Jefferson and Arapahoe counties. 80123 and 80128 are only partly inside Littleton city limits, so a Littleton mailing address doesn't tell you which government handles permits.
My bill comes from Denver Water. Who do I call about a leak in the street?
Usually your district. Platte Canyon and Southwest Metro have "read and bill" contracts: Denver Water reads the meter and sends the bill, but the district owns and repairs the pipes. Their shared line is 303-979-2333.
Why do I get a sewer bill from the City of Littleton?
Wastewater from Southwest Metro and neighboring districts flows into Littleton's interceptor sewer and is treated at South Platte Renew, which Littleton and Englewood own. Littleton bills district customers for treatment.
