Littleton is an old town with a lot of newer neighborhoods. The median home was built in 1982, but downtown and the historic districts like Arapaho Hills go back decades further.
Plumbing in Littleton
In the older parts of town, the calls are about sewer laterals and original galvanized pipe. In the 1980s and 90s subdivisions, it's water heaters, polybutylene or early PEX repairs, and fixtures wearing out on schedule. Littleton is served entirely by Denver Water, so Denver Water's programs apply: free lead service line replacement, up to $100 back on an efficient toilet, and its 2026 drought rules, which ended lawn watering after Sept. 30.
Common Littleton calls
- Water heaters 10 to 15 years old, ready for replacement
- Recurring kitchen and main line clogs in older homes
- Leaking or running toilets (and the rebate for replacing them)
- Frozen hose bibs and pipes in garages and crawl spaces
- Winterizing sprinkler systems that have to stay off into spring
