By removing this cap (a task requiring a large wrench and caution, as backed-up wastewater may spill out), the homeowner can determine if the clog lies between the house and the municipal sewer (if water drains slowly from the cleanout) or deeper within the house’s own branch lines (if the cleanout is dry but interior fixtures are clogged). how to unclog sewer drain
