Leaking drain pipe

Hi PrepHole,
This drain assembly keeps leaking at the circled region.
Multiple things drain here:
The laundry sink
The washing machine
Kitchen sink
Dishwasher

Water is seeping out of the circled connection when the kitchen sink/dish washer is in use

How can I stop this leak? Can I add some glue to this seepage region? Or does all of this PVC piping need to be replaced?

This house was built in 74 if that matters.

    Drain is plugged
    Coat entire mess in flexseal
    Or try putting radiator stop leak in drain

      You really think so?
      What makes you think the drain is clogged?

      Should I try draino or a similar plugged drain product?

        Do NOT use drano on that line. You should really snake it, but if you can’t do that you’d be better off with some concentrated vinegar. He’s suggesting it’s clogged because… well think about, how would an empty pipe leak? Generally if a drain line is leaking a significant amount of water it’s at least partially clogged at some point, causing a back up during peak usage that then drips out when the pipe is full.
        You can try to flex seal/marine glue the frick out of it, but cutting out a PVC coupling and replacing it isn’t THAT expensive. Can be done for less than 50$.
        If you want to be cheap I’ve had luck with that temporary silicon tape. I’ve used it plenty of times on drain lines to keep them dry until I have a chance to get the parts/time to do a proper repair. Seeing as this looks easily accessible it wouldn’t be a bad solution until you find something more permanent.

          i will never understand tinfoil hatters like you, who think vinegar is some magic substance
          yes, it might clean calcium or rust deposits, but i will do jack shit to hair and sludge, that is probably clogged OP's pipe

            My bad: I meant hot, spicy vinegar.

          Drano is fine for ABS pipes. Plumbers hate drano because it renders their shitty trade useless.

    drainpipes aren't under pressure, and ABS pipe like that won't leak unless it is either cracked, damaged or is holding water (plugged).
    snake it out, then clean up all the deposits around the pipe. wait a few days and see if it's till leaking. if it still is, you will need to either cut out that entire manifold of shit and replace it all, or flexseal it as the other anon said.

      I was kidding about flex seal.

              It would be back peddling had I been called out on it. My guess is your dumbass

    Needs redone entirely. Read on vents and do it better or call someone.

    Thanks for the responses guys

    So I think the course of action is:

    1) try to unclog this portion of the drain. Need to determine how to do this. Either chemically or with a snake.

    2) may be a way to topically seal the leak with glue of some sort

    3) may have to cut out this section and put a rubber boot with hose clamps on each side to bridge this section and repair locally

    4) cut out and replace all of this

    Sorry so I wanted to ask, since it is the kitchen sink/dishwasher that drain through this pipe that is leaking, and that is in the main floor and this photo in op is in our basement under our laundry sink, then I guess I'll be trying to unclog from the kitchen sink?
    Or could be I attempt to unclog from the laundry sink?

    Also which is the best product to use for either chemical or snake type product?

      You got a good plan, and I salute you for at least having a logic flow.

      First, do you have a power drill and do you have a snake/auger? If the answer is no to either or both, I would highly suggest you spend the 20 bucks and find a 15' or 25' auger with handle and drill bit attachment.

      Second, find the drain that is closest to this drain fixture OR has the clearest lateral line to this fixture. You're going to want the least amount of resistance when feeding the auger line into the drain.

      Chemical will likely not unclog, and even if it does, you're going to want the auger to fix this in the inevitable future clog.

      If you don't want to mess around with new PVC fixture, or cut into the existing, I would wait till this drain fixture is as dry as possible. Once you think it's dry, apply a coating of sealant around the entire circumference of the leaky area. Dry it with a hair dryer if necessary. Like the other anon said, there won't be any pressure but if the clog happens again, it'll fill up and find the weakest point to escape.

      Lastly, make sure your drains have catches for debris. Mesh sock on the washer drain tube, strainer in kitchen sink.

      Good luck

    that's a funny pile of crap. if it was backed up and clogged you could simply verify that by backing up the sink or checking to see if it starts leaking immediately. I wouldn't waste time on considering a clog unless you can at least get the sink backed up
    plenty of fittings will leak from regular flow if the glue fails and that glue doesn't look right at all
    if the leak is coming from the top of that t (which does not look like the appropriate sant lmao)
    I personally would cut above the hub, and remove the 90 after disconnecting whatever drain is running into it. use a rambit to clear the t hub and just replumb a 90 and stubout to that sink drain
    the only thing easier than that would be jb weld or abs glue that joint and pray

    Dry the joint, immediately before you leave for work. Assuming none of those things are being used, during the day, it should be dry when you get home. If it is - clean/rough up the joint and it's JBWeld-Time. Use the fast-drying version, as you don't need any kind of serious strength.

    Ok it's been 1.5 wks and I see this thread is still up.
    Here's a quick update...
    Nothing was backing up so may not have been a clog. The water would just seep from the fitting while water was running through the pipe.. so I think the glue failed there. I chatted to a relative plumber and he recommended some ABS glue similar to a few guys here so I fully dried The joint area and then sanded and then cleaned with alcohol and then applied three layers of ABS glue where the water was seeping out. So far it's been one and a half weeks and there has not been any more leaks so I'm pretty happy about that. Since this house is new to us and is old it probably would be good for us to snake some of these drains at some point but it seems maybe I got away without doing it for right now. Pic rel
