The job itself
How water service line work is done properly
Water Main & Service Line is handled by independent licensed professionals across Colorado. This page covers what the work involves, what changes the price, and the Colorado code and permit rules that apply — then links to the 37 largest markets where a local page exists.
- The service line is located and the loss confirmed at the meter
- Utility locates are called before any excavation
- Method is chosen — spot repair, pipe bursting, or open trench replacement
- New line is installed, pressure-tested and disinfected where required
- Surface is restored and the work inspected
Scope boundary
What a standard visit covers — and what is billed on top
The single biggest source of quote disputes is the boundary between these two columns. Get it written down before work starts.
| Normally included | Commonly billed on top |
|---|---|
| Pressure testing, flushing and restoring water service to the property | Tree root removal, rock excavation or dewatering an unstable trench |
| Locating the service line and confirming loss at the meter | Permit, right-of-way and utility connection fees set by the jurisdiction |
| Utility locate requests placed before any digging begins | Driveway, sidewalk and lawn reinstatement over the excavation route |

Answers first
Water Main in Colorado — frequently asked
Who owns the water service line?
Typically the property owner owns from the meter to the house, and the utility owns from the main to the meter — but the boundary and the rules around lead service lines vary by jurisdiction. Confirm with your water utility before authorising work.
Should I replace a lead service line?
Replacement is strongly recommended and in many jurisdictions is being required or subsidised on a schedule. Ask your utility whether a replacement programme or cost-share applies to your address before paying full price.
Do I need a pressure regulator?
If static street pressure exceeds the code threshold — commonly 80 psi — a pressure-reducing valve is required and protects every fixture and appliance in the house. A licensed plumber can measure static pressure in minutes.
Who handles the permit for water main in Colorado?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the licence.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberColorado is not a party to the agreement. Ask for labour and parts warranty terms in the quote, and keep the licence number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberColorado cover?
All of Colorado: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
Is PlumberColorado a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberColorado routes the request and links every page to the official Colorado licence register.
