Leaking Toilet Drain Pipe

While in the crawl space last night, I noticed a puddle. After further looking, it seems the joint failed for the PVC drain at one of my bathrooms. Not only is this leaking but whoever installed this left no room for cutting and adding an attachment to it.

Once this pipe is no longer visible in picture, it is going through the floor and attached to the toilet. If I am looking at this right, the whole 3 way connection needs to be removed along with the toilet and redone. Anyone else have easier suggestions?

I think you've got the right idea. You'll probably have to end up replacing everything from the 3-way up. Depending on whether or not you can move the other plumbing enough to get the joints put together you may also want to pick up a couple no hub couplings (rubber boot) to go on either side of the 3-way.

Also, I cant see whats in the other bay, but is there a vent? Any trouble with water getting siphoned from the toilet?

If your going to the trouble of taking the pipe apart this far you may consider a different layout if its not piped correctly as is.

Just my thoughts.

If I am seeing what I think I am seeing there are some major defects in that plumbing arrangement. If it works okay I would be tempted to let sleeping dogs lie and just clean off the leaking joint and daub some heavy-bodied PVC cement into and onto the joint.

It is leaking where the elbow (at top) meets the T fitting. I really hate to rig anything and would prefer to fix it correctly as this bathroom is used daily.

Yes there is a vent pipe elsewhere.

Yesterday we got under the bathroom and cut the piping loose. Only to find out the reason it was leaking was because the pipe at the top of the "tee" fitting was not glued to the elbow going through the floor. We put a new "tee" in and couplers and all is well now.

It may work but it isn't right. Very few times when it is okay to put a sanitary tee "on its back" and this isn't one of them.

When you come from vertical to horizontal it must be a sweep. Most likely a Y with a st 45.

Plus again I bring up venting if that TY goes to the toilet. I see no vent.

Pipe to the left with the elbow in it is the vent.
