Decision to make
Stop contaminated overflow use and keep people away. List the lowest affected opening, other fixtures on the same level, recent use, weather, and verified public notices.
Record to build
A single fixture may involve its trap, branch, vent, or a wider line. Several fixtures can share a branch, building drain, private sewer, septic, or municipal influence. Preserve these as alternatives.
Question to compare
Ask where testing begins, how access is protected, what fixtures are tested afterward, when camera or locating is useful, and when Stoughton or another wastewater party should be contacted.
Useful closeout
Do not convert a successful clearing into proof that the pipe has no defect. Keep the method, recovered material description, observed pipe condition, limitations, and recurrence plan.
