Claim:
A cleanout with drainage capabilities, comprising: a first body having a first sidewall and a top access opening, the first sidewall having a plurality of circumferentially spaced and axially oriented first slots; a removable closure closing the top access opening; a second body having a second sidewall and a bottom access opening, the second sidewall having a plurality of circumferentially spaced and axially oriented second slots; the first body and the second body being rotatably engaged with the first sidewall and the second sidewall overlapping, a slot open flow area being provided where the first slots and the second slots overlap, relative rotation of the first body and the second body altering the relative circumferential spacing of the first slots and the second slots placing them either out of register, partially in register or fully in register and thereby altering the width of the slot open flow area; and the first body and the second body having limited axial movement toward and away from each other, relative axial movement of the first body and the second body adjusting the combined length of the axially oriented first slots and the axially oriented second slots to increase the slot open flow area linearly throughout the limited axial movement of the first body and the second body.
