Spears P706X-015 – Frequently Asked Questions
1) What sizes does the Spears P706X PVC DWV P-trap come in?
Two sizes: 1-1/2 inch (P706X-015) and 4 inch (P706X-040). Both are hub x hub, so each end takes PVC DWV pipe of the matching size and is joined with solvent cement. The 1-1/2 inch is the fixture-trap size for lavatories and similar fixtures; the 4 inch is used where a full 4 inch DWV branch or floor drain run needs to be trapped.
2) Can I thread the Spears P706X P-trap onto a tailpiece or a threaded drain?
No. Both ends of the P706X are hubs (socket), made to be solvent cemented to PVC DWV pipe. There are no threads and no slip-joint nuts, so it will not screw onto a fixture tailpiece or a male-threaded drain. If you need a serviceable connection at a fixture, use a slip-joint trap or add a threaded adapter to the pipe ahead of the hub.
3) Is a 4 inch P-trap the right choice for a kitchen or bath fixture?
Usually not. For a lavatory or kitchen sink the 1-1/2 inch P706X-015 is the size that matches the fixture drain. The 4 inch P706X-040 is for 4 inch DWV lines, typically floor drains or branch runs, and putting it on a small fixture oversizes the trap and slows the flow needed to keep the seal scoured.
4) Is this P-trap serviceable, or do I have to cut it out to clean it?
The P706X is a cemented-in fitting with no cleanout plug and no union nuts, so once the joints are solvent welded the trap is permanent. Clearing is done through the fixture or a downstream cleanout, and replacement means cutting it out and splicing in with couplings. On fixtures you expect to pull apart regularly, a slip-joint trap is the better choice.
5) Will a PVC DWV P-trap work on a floor drain or trap arm rough-in?
Yes, that is a normal use for the P706X. It is specified for fixture trap arms, floor drains, and other DWV rough-in points where a hub connection is wanted on both ends. The curved body holds the water seal that keeps sewer gas out of the space, so the trap must stay below the fixture outlet and be vented per your local code.
6) Can I use the Spears P706X P-trap on a hot water or chemical waste line?
It is a PVC drain-waste-vent fitting, built for gravity drainage of ordinary wastewater in residential and commercial plumbing. PVC gives corrosion and chemical resistance in drainage service, but DWV fittings are not pressure fittings and are not intended for high-temperature discharge or acid waste. For lab or acid waste, specify a system made for that duty.
