1.25 in. Rubber Threaded P-Trap Bathroom Single Sink Drain Kit

Hello, yes the black connector is a threaded fitting for 1.5” threads. The blue piece and the washer are only used for 1.25” and only in the single kit. If you have the double basin for kitchens then it is only set up for 1.5” threads. If you need any addition help please reach out to simpledrain@crushproof.com Thanks, Jason

The double basin kit for kitchens comes with 2 hoses that are 24" long but they get trimmed into 3 pieces, 1 to each basin connected to the tee and 1 from the tee to the waste line. Each cut piece is likely much shorter depending on your installation. If you would like to see some installations we have examples and walkthroughs on www.simpledrain.com/videos. Or if you have specific questions about your install you can always reach out to us at simpledrain@crushproof.com and I'll be happy to help! Thanks for reaching out.

Hi Marc, see below, but for more specific guidance please reach out to simpledrain@crushproof.com. The hose forming the trap should be dry measured before trimming to length. When cut and held in place with the trap loop piece the small piece on the loop can be bent down to confirm that the trap is 2" in depth and if there's a little gap that's ok as per code the trap should be 2-4" below the waste line. The hoses touching usually wouldn't need to happen to complete the install, but I've seen some strange set ups work and would be happy to take a look at your install to confirm your set up will work as intended. Please let us know if you have additional questions. Thanks for using Simple Drain!

Hello, Simple Drain is designed to fit both 1.5" waste lines standard, and 1.25" wastelines with our blue adaptor and gasket that comes in every kit, as long as the wasteline has threads Simple Drain will connect with those sizes. If you'd like to see any examples of how to install these check out www.simpledrain.com/videos for more guidance! Thanks for considering Simple Drain!

Can this part go from intimate quarter to fit inch and a half wall piece

Hi Rick, maybe but most tub drains are 2” and Simple Drain is designed to fit 1.5” or 1.25” so I doubt it. You could glue a reducer bushing on and it would work but I would not recommend reducing the size. Thanks for reaching out.

Either the single kit or the double kit will work with a kitchen depending on your set up. Simpledrain.com/videos can show you an installation and give you a better idea of what would work for you! If you have any questions you can reach us directly at simpledrain@crushproof.com with any pictures to help clarify what will work for you!

The threaded connectors do not thread onto the tee. The hose is designed to be clamped on the tee. You can use any of the cut tubes clamped onto the tee or other pipes, I wouldn’t recommend this if the clamp is below a water line (I’ve never had one leak doing this but always fear it) but it would be seal against flowing water. Thanks for reaching out!

The black threaded fitting is designed to fit 1.5” threads and the blue adapter fits on 1.25” threads if needed for the black fitting to fit on top of that blue piece if needed on a smaller waste line. Thanks, Jason
