OATEY 86033 3" or 4" ABS Sediment Drain, Cast Iron Grate w/ Bucket

Both. The Oatey 86033 is an ABS sediment drain built to take either a 3 inch or a 4 inch connection, so you can use the same body whether the branch under the floor is 3 or 4 inch ABS.

It is a floor drain with a removable catch bucket sitting under a cast iron grate. Debris, grit and sediment drop into the bucket instead of running down the line, and you lift the grate and dump the bucket on a maintenance round. That makes it the right pick for car washes, mop rooms, mechanical rooms and shop floors where a plain floor drain would silt up the branch. If nothing solid is coming off the floor, a standard floor drain without a bucket is the simpler choice.

Cast iron grate on an ABS body. The iron top takes the foot and cart traffic while the plastic body handles the drainage connection, so it holds up better underfoot than an all-plastic drain.

Order Oatey 86033. That one model number covers the ABS sediment drain, the cast iron grate and the sediment bucket together, and it carries UPC 038753860336.

The body is ABS, so it solvent cements to ABS DWV pipe with ABS cement at either the 3 inch or 4 inch size. If the line in the floor is PVC, you are joining two different plastics and that needs a transition fitting or a mechanical coupling rather than straight ABS cement.

It ships at 23 lb, most of that in the cast iron grate. One person can set it, but plan the rough-in height before you drop it in rather than wrestling it twice.
