Select Components

A standard sink set-up requires a P-trap, trap adaptor and tailpiece. Extensions and trap offsets may be required if your sink and wall connection do not align. For kitchens, double bowls, dishwashers and garbage disposals will require additional products.

    You may need to buy a 'flange' washer separately
    There are two methods of installing this. One is via 'Slip Joint Connection'. The other is via 'Direct Connection'. If you do it via 'Direct Connection' you need to buy the 'H' Flange Washer separately because it is not included. That part is #1000 050 069 - 1 1/2" Oatey Washers. Another # is HDC7195C.

      Good d/w branch tailpiece
      I ordered this dishwasher branch tailpiece when I was replacing my sink. It was easy to connect to the sink and dishwasher drain tube. I had to cut the branch down so it wasn’t so long and then attach a plumbing clip just to make sure the dishwasher drain tube stayed securely in place. This branch tailpiece came with a few extra size adjusting washers and screw on cap things so you can transition to/from 1/2 to 3/4. If you need a d/w branch tailpiece I would recommend you take a look at this one.

      A better design
      So, in the picture it looks like the standard dishwasher tail piece that has a slip joint nut that points upward - which is normal. However, that design isn't ideal as that nut cannot be replaced and they are a booger to connect a plastic nut to a metal basket strainer. THIS is a much better design in that it has a small tailpiece that fits into the dishwasher leg. This is how it should be done.

      Perfect for dishwasher hookup
      This this is the perfect tailpiece for your dishwasher hookup. Nice quality and comes complete with everything you need to hook up your dishwasher to your drain line. Just remove your old tailpiece and put this one into place also can be cut to length. Hook up your dishwasher drain hose and clamp to the stem sticking out and your job is done. Simple and easy to install.

      The picture shows the direct connect tail piece. The item...
      The picture shows the direct connect tail piece. The item shipped was a slop joint connection. Wrong . But I used it anyway. Picture is correct but wrong item shipped.

      confusing to even make this work when you have a double sink. we ended up cutting everything really short. So there need to be another option with the double sink and the dishwasher.

      Nuts are not made properly.
      The nut openings are too big for the gasket and will not seal properly.
