Installation Versus Replacement on a Water Tap
Installation applies to new construction, a property adding a service where none exists, or splitting a shared water service into individual connections. The main design question is correct sizing for the intended use now and reasonably into the future, since undersizing a tap creates pressure problems that are expensive to correct later.
Replacement applies where an existing tap has failed at or near the main, commonly discovered through unexplained water loss, low pressure that traces back to the curb stop area, or visible water surfacing at the tap location. Corrosion at the connection, particularly on older galvanized or lead services, is a frequent cause on older Denver metro properties.
(720) 935-6221Signs a water tap needs replacement
- Water surfacing at or near the curb stop with no other explanation.
- Unexplained increase in water usage or bill.
- Persistent low pressure traced back to the service connection.
- Corroded or failing curb stop or corporation stop hardware.
- A shared tap needing to be split into separate metered services.

How Water Tap Installation and Replacement Runs
- 1
Locate the main and verify main size and material
Depth, diameter, and material at the main are confirmed and matched against the service size needed.
- 2
Coordinate with the water authority having jurisdiction
Sizing, connection type, and permit requirements are confirmed with the utility before excavation.
- 3
Right-of-way and traffic control permitting
Street cut and traffic control permits are secured where the tap sits in a public right of way.
- 4
Potholing and utility locates
The connection area is exposed carefully and other utilities are located first.
- 5
Tapping sleeve and valve or direct tap, with thrust restraint
The connection is made to the approved detail with restraint set at the fitting.
- 6
Pressure test, disinfection, and clearance
The new or replaced service is pressure tested, disinfected, and cleared before it is activated.

What Denver Customers Say About Working With Us

What Drives Tap Installation and Replacement Cost
Service size, main depth, distance from the building, and whether restoration is in lawn, driveway, or street pavement are the leading factors. Replacement can add cost where old hardware at the connection is corroded and needs careful removal before the new tap goes in.
Tap fees and system development charges are set by the water utility with jurisdiction over your address, not by us, and we confirm current figures with the utility rather than publishing amounts here.
