Encourage replacing lead service lines encountered during your work, whether it's installing sprinkler systems or selling a home. By taking a proactive role, you will lend your expertise while showing customers your concern for their health and safety.
Replace, don’t repair
If a lead service line has a leak, it should be replaced with copper in full, not just repaired. It's important to know the appropriate scope of work required to safely replace a service line.
Steps for professional service line replacement
- Obtain permits from Denver Water and the local permitting office.
- Call Water Sales Administration at 303-628-6100 to schedule a tap cut at the main.
- Replace the existing water supply pipe from the main to the water shutoff inside the home foundation using a continuous type K copper pipe (see Denver Water's Engineering Standards). If the indoor main water shutoff shows signs of deterioration or malfunction, replace it. When connecting a copper pipe to galvanized steel, be sure to use a dielectric union.
- Do not use splices or solder joints. Use lead-free bronze for all fittings at the meter, including the yoke.
- Backfill and compact excavations to standard.
- Replace the meter pit with new approved material (see the Engineering Standards).
- Schedule and pass all inspections. Contractors are responsible for rework.
