How the sewer dye test process works
Most Allegheny County municipalities require a dye test before a sale. A plumber puts dye into downspouts, area drains and yard drains to prove that stormwater is not flowing into the sanitary sewer. Some also require a camera inspection of the lateral.
- Hire a licensed, Allegheny County registered plumber. Some municipalities require a plumber from their approved list, or do the test themselves.
- The plumber runs dye through downspouts and drains and completes the municipal form.
- If dye shows up in the sanitary line, the illegal connection must be fixed and the test redone.
- The municipality issues a certificate. It must be on file before the lien letter and tax certification are released for closing.
| Item | Typical range |
|---|---|
| Municipal certificate fee | $20 to $350 |
| Downspout or drain disconnection | $300 to $3,000 |
| Lateral repair or replacement | $3,000 to $15,000 or more |
