I've installed a new closet toilet but had a problem with the rough in and needed to extend with a 3in PVC pipe outside of an existing T connect in order to install the flange. Thought I had a good seal but after a month the joint is starting to leak. Is there a way to seal or do I need to replace the entire drain

The cap was cut off and a 3 in pipe was cemented overtop the connected to a flange

how much pipe was in the hub of the flange
you could use one of these

The flange isn't what's leaking its the 3 in PVC pipe I used to extend around the current cap u see

If it were me, I'd get rid of the side-inlet 90 altogether since it doesn't meet code and will only cause problems in the future. Install a 3" x 2" wye and 2" street 45 to pick up the 2" branch, then continue on with a new closet bend and flange - done.

Here's the pick as it stands now

So...what you really did was you tried to glue a short length of 4" PVC over the hub of a 3" fitting. Of course it's gonna leak! :no: Cut it all out like I said above and redo it properly.

if the cap was cutoff there wasn't enough pipe sticking out of the elbow to get a good connection on. need to replace the elbow to make it right

what the heck

This will keep the drain cleaners in business. 2x Ishmael. You could also try that handyman in a can stuff and post back if it works

Wow... The toilet drain has to be one of the worst things to try and half-ass. If your determined to fix it without tearing the whole thing apart (maybe your renting or selling? lol), you could try using a rubber coupling with the ring clamps on each ends. Those things are damn good once you get them snugged down - the main tee in my house uses one to go from 4" black iron to 4" PVC.

what fixture drains into the side inlet?

Like Ishmael said, get rid of the side-inlet 90

what fixture drains into the side inlet?

Bathroom sink drains there

I just installed a sink in garage and still had this photo. For you, imagine that fitting "A" is picking up your bathroom sink and that fitting "B" is not the 2x2x1.5 wye as shown but is instead the long sweep 90 with the closet flange that picks up the toilet.

kind of like this: the only flange drawing I had was an offset one but you get the idea
