DIY Plumbing Repair

I think if you turned the last pipe going into the wall slightly counter clockwise and used a solid pipe you could eliminate the flexpipe. You should line everything up plumb before tightning the nuts. The problem with gluing is.... that if the pipe becomes clogged you end up having to replace all the piping.

That's why you have a cleanout port and just glue everything. I used to get leaks every few years with the setup the OP has, every time there's a new leak, I just swap everything out to black abs and glue and no more leaks. And those leaks tend to ruin the vanity and cause other damage.

^Yes - under sink is not accessed very often so a small leak can go unnoticed for weeks and months. It took 3 months of a not noticeable leak under my kitchen sink to make a good size permanent reminder on the cabinet floor, I can only imagine not noting it for 6+ months could cause.

Get a real P trap made of 1 1/2 PVC sched 40. Use no hub adapters. They are rubber hose like adapters using hose clamps.

My 2 cents:

1) Water Alarm under sink
2) Large Cooking Tray or Moisture Detecting Paper under sink plumbing
3) Motion Activated Lights inside cabinet so when you open the door, you can look for any leaks
4) Once a year, I check the whole house for any plumbing leaks

I had those weird screw on gasket things under my kitchen sink. I don't understand how they work. I've replaced them multiple times and they just leak within a week. I finally got pipe and glued it all.

I think one large factor in leaks with slip joint fittings like this is the crummy plastic washers. Whenever I install them, I pitch the plastic washers and use rubber ones. I think the rubber ones seal much better and tend to stay secure. They're typically under a dollar apiece (the plastic ones are less than a dime), but well worth the small price.

Also, over tightening (and under tightening) will guarantee a leak.

On the plus side, it appears the OP eliminated what looks like a S-trap in the original installation.

I am surprised how many people in this thread are using glued sink drain connections. I rarely see them here in Michigan.

Yes, the guest bathroom has a similar set up but no glue. It is not leaking either.
