OATEY P9718 Dearborn® 1-1/4" S-Trap w/ PVC Solvent Weld Adapter

The P9718 ships with 3 slip joint nuts and 2 washers, so the trap connections are covered out of the box. What it does not include is the solvent cement for gluing the PVC adapter into your drain line, and any escutcheon or wall tubing you may want for the finished look.

Same 1-1/4 inch polypropylene S-trap either way; the difference is how it ties into the drain. The P9718 carries a PVC solvent weld adapter, meaning you glue it into PVC drain pipe with solvent cement. The ABS threaded adapter version threads on instead. Pick the one that matches the drain material and connection already in the wall or floor.

An S-trap like the Dearborn P9718 is for drains that run down through the floor rather than back into the wall. If your drain stub comes out of the wall, you want a P-trap instead. Many jurisdictions restrict S-traps on new work because they can siphon the seal dry, so check your local code before specifying one; they are most often used for like-for-like replacement on existing floor-drain plumbing.

Yes. It is a 1-1/4 inch trap with slip joint connections, which is the standard size for bathroom lavatory drains. The slip nuts and washers let you slide onto a 1-1/4 inch tailpiece and adjust the height before tightening, so minor misalignment between the sink and the floor drain is easy to take up.

Polypropylene is the standard plastic for drainage traps and it will not corrode or pit the way a thin-wall chrome-plated brass trap does under constant use and cleaning chemicals. For a property manager standardizing across units, the P9718 is a white plastic trap you can stock in quantity and swap without a torch or specialty tools. Where the trap is exposed under a wall-hung fixture and appearance matters, a chrome tubular trap is the usual choice instead.

Order it as Oatey P9718. That is the Dearborn 1-1/4 inch polypropylene S-trap supplied with the PVC solvent weld adapter, nuts and washers included. The ABS threaded adapter build is a separate part number, so quote the P9718 specifically if the drain is PVC.

Each P9718 trap is 0.55 pounds with a volume of 0.161, which is why these ship cheaply by the case for MRO stock. Light enough that a service van can carry a dozen without thinking about it.
