A Lone Tree plumbing inspection covers the water heater, supply and drain piping, shutoffs, fixtures and pressure, and can include a camera run of the sewer lateral. Lone Tree is a newer planned city, so the inspection usually looks at wear and workmanship rather than very old pipe. Call the number on this page to be connected with a local plumber in Lone Tree.
Lone Tree's water and sewer depend on which side of I-25 you live on. Southgate Water and Sanitation Districts serve the west side, distributing Denver Water's drinking water, and Parker Water and Sanitation District serves the east side. Some Terra Ridge homes along Indian Wells Drive are on Northern Douglas County Water and Sanitation District. Southgate reminds owners that they own the buried water service line and sewer lateral serving their property.
Steps to take now
- Confirm which district serves the address, using the bill or the city's utility providers page.
- Find the water heater's install date. Many homes still have their original unit.
- Decide on a sewer camera run. On Southgate's side the lateral is yours, so its condition is your cost.
- Note whether there is an irrigation system and ask for any backflow test records.
- Clear access to the utility room, cleanout and any crawl space.
- Plan to be on site at the end so the plumber can explain findings in person.
Symptoms and likely causes
| What shows up | Likely cause |
|---|---|
| Relief valve on the water heater dripping | Thermal expansion, high pressure or a worn valve |
| Water spots under an upstairs bath | Leaking shower valve, drain or supply connection |
| Main drain slow after heavy use | Partial blockage or a low spot in the lateral |
| Faucets with mineral crust | Moderately hard water; west of I-25, Denver Water reports about 105 ppm |
| Banging pipes | Water hammer or loose pipe straps |
What sets the cost
- Square footage and the number of bathrooms
- Tankless or multiple water heaters
- Whether the camera run is included
- Finished basements that hide piping
- Written findings for a contract
East of I-25, ask Parker Water and Sanitation District about its own service line and backflow rules, since they may differ from Southgate's. The plumber's notes on the line's material and the main shutoff are useful either way.
Lone Tree requires a permit for work on plumbing, gas, mechanical or electrical systems, including new water heaters and in-home sewer line repairs; clearing a stoppage or fixing a drain or supply leak typically does not need one. Applications go through the city's Accela portal. Gas comes from Xcel Energy: if you smell gas, leave first, then call 911 and Xcel at 1-800-895-2999.
