Sewer Line Tap Repair in Denver
An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.
Sewer line tap repair fixes a leaking, offset, or root-damaged connection at the sanitary main without necessarily replacing the entire tap. Denver Sewer and Water scopes the connection first to confirm the failure is repairable before recommending anything more invasive.
- Repair of leaking, offset, or damaged tap connections.
- Camera confirmation that the failure is at the tap, not further out.
- Root cutting and joint resealing where the connection allows it.
- Excavation limited to the failed connection point.
- Full replacement recommended only when repair will not hold.

What Causes a Sewer Tap Connection to Fail?
Joint failure at the connection point is the most common cause, whether from a boot seal degrading over time, a saddle strap loosening, or ground movement shifting the service line relative to the main. Root intrusion is a close second, since roots seek out any gap at a joint and can wedge a seal open wider over time.
Less commonly, the failure is structural: the main itself has deteriorated around the connection point, or the connection was made improperly in the first place and was never sound. That distinction matters, because a seal failure can often be repaired where a structural failure at the main cannot.
(720) 935-6221Signs of a failing tap connection
- Water or sewage surfacing directly over the connection point.
- Root mass visible on camera right at the tap.
- Recurring backups that clear with cleaning but return quickly.
- A slight offset visible on camera where the service meets the main.
- Soil settlement directly above the connection.
How We Diagnose It
Confirming the Failure Is Actually at the Tap
Backups and slow drainage can originate anywhere along a service line, not just at the tap, so we camera the full run before assuming the connection itself is the problem. Where the defect shows up right at the point of connection to the main, that confirms tap repair is the correct scope rather than a repair further out in the yard.
The camera also shows whether the connection's structural integrity is intact enough for a repair to hold, or whether the joint and surrounding pipe are too deteriorated for anything short of replacement.
What the inspection confirms before repair
- Exact location of the defect relative to the main.
- Whether the failure is a seal issue or a structural one.
- Root mass extent at the connection.
- Condition of the main itself around the tap.
How Sewer Tap Repair Runs
- 1
Locate the tap and verify main size and material
The connection point is confirmed on camera and located on the surface before excavation.
- 2
Coordinate with the wastewater authority having jurisdiction
Repair scope and any required inspection are confirmed with the authority before work begins.
- 3
Potholing and utility locates
The connection is exposed carefully with other utilities in the area located first.
- 4
Root cutting or joint repair at the connection
Roots are cut back and the seal or restraint at the joint is repaired or replaced.
- 5
Pressure or leak verification
The repaired connection is checked to confirm it holds before backfill.
- 6
Inspection sign-off and surface restoration to spec
The authority inspects the repair, then the trench is backfilled, compacted, and restored.
What Denver Customers Say About Working With Us
“Very direct and to the point. Extremely efficient and professional.”
“They cleared our drain where Roto Rooter couldn't and quoted us to replace the line under our concrete.”
“Prompt service and worked well into the night to restore service due to hard soil. And did their best to prevent large scars to the yard”
What Drives Sewer Tap Repair Cost
Depth to the connection and how much of the main has to be exposed to reach it are the main cost drivers, along with whether the repair is a straightforward reseal or involves cutting out root mass and rebuilding the joint. A repair that turns out to require full replacement once excavated adds cost beyond the original scope.
Any permit or inspection fee required by the wastewater authority is set by that authority, not by us, and we confirm current figures before scheduling rather than quoting amounts here.
