Replaced Kitchen Sink Pipe - Still Leaking


Hello-
I just tore out all the prior PVC pipes under my sinks as they were leaking.
I replaced the faucet as well as installed a garbage disposal. My hangup is I have never done this before and the PVC pipes are leaking. I applied sealant and it still leaks. I have added a pic. Any help would be appreciated.
Thanks.

I have no idea what that grey stuff is, totally unnecessary if you get the pieces properly aligned, and use the correct gaskets. My guess is you have the wrong pieces. There are plastic gaskets that must be used in each connection. There are at least two sizes, depending on the type of pipe you are connecting to. Go to a plumbing supply store, they will have the right pieces. Show them what you need to connect, they will get you the right parts. And make sure the pieces align properly, you can get a leak if the pipes you are connecting are not straight.

All the wrong fittings, and ran wrong. Toss all that and redo it something like this.

Call a real plumber, please. No vent, Illegal trap that will siphon.

I know it looks worse with all that gray stuff around it. I really don't have the money for a plumber. I just am not sure what exact pieces to get, like the connectors. The job before me was even worse. If anyone has like a link to the parts i need, thanks guys

Post one more picture from a little further back--If we can see the pipe from the bottom of the cabinet--someone can help---

All that you have there is going to need to be replaced.

Ready to start over?


You will need the following---about 3 feet of 1 1/2'' pvc pipe--a sanitary T- a 45* street elbow.--a threaded female adapter --an AAV--(Air Admitance valve) and a trap adapter.

First thing---remove all existing drain piping---leave the rubber fitting at the floor---

1--install a new P-trap to the garbage disposer---be sure you put the nylon washer on correctly--wide side to the nut--thin side to the fitting---

2 Loosen the disposer just enough that you can turn it ---

3 temporarily put the trap adapter and sanitary T onto the P-trap arm---swing the assembly so it is over the pipe in the bottom of the cabinet.( you may need to turn the disposer to get the aim right)


4 cut and install a section of pipe from the rubber boot to the bottom of the sanitary T---

5-add a section of pipe to the top of the T--with the female addapter and AAV attached---you want this as close to the bottom of the counter top as you can--

If everything fits---prime and glue using the proper stuff for PVC.--Tighten up the compression nuts on the P-trap---tighten up the disposer.

In a nut shell---you need a drain straight up from the rubber boot---to a T--then up to a vent-(AAV)

Always put the P-trap on to the disposer first----that's how you know where the T- needs to be--and how it must face for the P=trap to enter it.

Another thing I noticed is the bigbox parts have become nothing but unusable. I would only use parts from a supply house, here at least they are much cheaper than a big box.

Thanks Creeper----we all have strengths and weaknesses---

I can't figure out computers----I could carve one out of wood--but I can't post a picture---go figure---I would like to see a picture of a windmill---

This is pretty much what mike described- but instead of the sink tailpiece, you have the disposal. Oh, and throw away the caulky stuff
