Minnesota Administrative Rules

4715.1000 LOCATION.

There shall be at least two cleanouts in the building drain, one at or near the base of the stack and one near the connection between the building drain and the building sewer. The cleanout at the outside wall may be inside or outside the building, and shall be made with a full "Y" branch fitting and shall extend at least two inches above grade or finished floor, except that the administrative authority may grant permission to use a flush cover in traffic areas.

A cleanout which is easily accessible shall be provided at or near the foot of each vertical soil or waste stack and each vertical storm water leader.

Each horizontal branch drain pipe shall be provided with a cleanout at its upper terminal, except that a fixture trap or a fixture with an integral trap, readily removable without disturbing concealed piping, may be accepted as a cleanout equivalent for this purpose.

All floor-set fixture drains with concealed traps such as floor drains, trench drains, and similar fixtures installed in areas receiving fouling waste shall be provided with an integral cleanout or a cleanout installed as close as possible to the fixture on the horizontal fixture branch serving the fixture. This cleanout shall be the same nominal pipe size as the horizontal fixture branch.

A floor drain cleanout may be omitted if the floor drain or fixture branch line is less than five feet in length.

Floor drains used for shower drains, recessed slop, or similar receptors may have the full-sized cleanout installed on the individual vent pipe serving the fixture or on the fixture.

A trap opening from a lavatory, drinking fountain, urinal, sink, or similar fixture may serve as a cleanout for a horizontal branch drain up to two inches in size, if the drain opening is not more than one pipe size smaller than the horizontal branch drain.

A cleanout shall be provided on a common vertical fixture drain or common vent serving two fixture traps that connect to a vertical drain at the same level. The cleanout shall be the same nominal pipe size as the drain serving the fixtures. Where the vertical drain is accessible through the trap opening, the cleanout may be eliminated.
