Homes and plumbing in Denver
Most houses have basements with a floor drain and a sewer line leaving below the slab. Soils along the Front Range contain expansive clay that heaves and settles, shifting sewer pipe out of alignment. Sprinkler systems and hose bibs need to be winterized each fall.
Clay sewer lines
Roots and offset joints in clay pipe are the leading cause of basement backups in older Denver homes. Sewer scopes are a standard part of home sales here.
Lead service lines
Denver Water is replacing lead service lines at no direct charge to homeowners under a program that began in 2020, and it provides filters in the meantime.
Freezing and altitude
Temperature can fall 40 degrees in a few hours, freezing pipes in exterior walls and crawl spaces. Gas water heaters must be rated and adjusted for high altitude to burn and vent correctly.
