Clean-out

A clean-out is a point of entry into the main sewer-line which conveys storm-water and/or wastewater from the home. Access can be gained via a sump (located inside or outside), a stack, or a stand-pipe connected to the sewer connection.

A toilet stub is not recognized as a proper clean-out and can be difficult to work from. The effectiveness of clearing and cleaning a blockage from a toilet stub is questionable due to the many pipe bends.

In most cases it is beneficial to install the clean-out as close to the house as possible in order to access the greatest portion of pipe. Note that the stand-pipe portion of the clean-out needs to be installed toward the direction of flow.

Do not substitute “Tee” fittings or 90 degree bends for a 45 degree long radius bend wye (see illustration)
