Can't fit slip nut because of dishwasher line
1 Attachment(s)
A few days ago the slip nut connecting the strainer in my kitchen sink to the pipe corroded and split. I bought a new slip nut to fix it but I can't fit it on because the dishwasher line is welded to the pipe (see picture)! Any suggestions on how I can attach the
strainer to the pipe and make my kitchen sink usable again.

I think your going to need a new pipe to the strainer that has the nut already on it and a dishwasher connection

I had a similar problem. I bought a plastic slipnut and a stainless steel 3" band clamp. I cut the tabs off the slipnut, then made one vertical cut completely thru the nut.

I used a dremmel with a cutoff wheel, a fine tooth jigsaw should be ok.

That let me pull the ends apart enough to get it over the pipe. I then put the s.s. Band around the nut and tightened the screw.

I had a functional slipnut without disassembling the pipe.

The main thing is to get all the plastic "sawdust" off the threads so they match.

Get a new tail piece with a dishwasher connection. Available in PVC for a few dollars.

It seems you'll have to first disconnect the dishwashing supply line and (clamp), then take off your tail piece, then you can put your tail pieces metal lock nut on over top, don't forget your tail piece's plastic washer too. then you should be good to go.:)

+1. I agree. Just unclamp the DW line. Remove the piece from the bottom of the sink, and get a new PVC one at any home center. They are available in metal also if you wish. I would stick with PVC. And yes...only a few bucks, and 10 minutes if that.

when you get the new plastic one, make sure that you get the one that has a 5/8 tee instead of the 7/8 version. also, get a new tailpiece gasket for it to avoid the second trip to the store :laughing:

Yeah don't try to fix what you have. Just replace it. All you need is a dishwasher tailpiece. If your p-trap is metal too, I'd just pick up a new PVC one as well. Don't mismatch parts. (i.e. plastic to metal)
