Coraggated pipe seam leak

[Newguy]

I used some 4" corrugated pipe to connect the back downspout into the front downspout using a tee and then out too into the front yard.
At the tee however, water comes out, I was wondering it there is any thing I can use to seal up that seam?
I was thinking brewer's cote didn't know if it might eat through? or caulking to seal it up tight any thoughts on which way's best..
or should I just leave it?

That type of piping isn't really supposed to be totally leak free. It just conveys the bulk of the water. Regular PVC would be the better option for a totally leak free installation. Unless there's special trouble, the black corrougated is normally what's used for downspout drainage.

Make sure your piping is inserted all the way into the tee. Usualy a few ribs of the pipe will snap in before it bottoms out. Put some gravel around the fitting (to help with erosion and to disapate the water that does leak out) then bury it and forget it.

Bishop makes a self vulcanizing black rubber tape that is about 4 inches wide and comes in a roll. You may be able to get this at an electric supply shop. Make sure the pipe is clean of debris where the tape will come into contact with the pipe. As you apply the tape you can stretch it and it will adhere to the pipe.

are you laying the pipe on top of the ground as a temporary drain. once you bury the pipe, the dirt that gets packed around it seals it.
i prefer wyes to tees when connecting downspouts together...smoother water flow.

I wasn't expecting this many replies lol :)

It is a semi-temporary drain (you know how that usually ends up lol) , meaning its going to be there quite a while and we will replace it eventually, unfortunately burial it isn't an option at the moment, I don't have a photo handy, but the driveway goes down that side of the house and whomever did it blocked up the perimeter drain that was there, (it was quite old well over 30 years. The house is over 100 years old, so I doubt it worked anyway.
They also graded the cement wrong so its puddling and then going under the cement porch, which we are afraid could develop a cavern under it, if left any longer.
Thats why we opted for the pipe laying on top of the cement and running it out the front I just wanted to get it far from the house as possible.

Thanks for the help :)

try some polyurethane caulking...take the fitting apart and put some on both parts, filling the corrugations. make sure you get it to snap all the way back together. hose clamps might offer some help, but probably aren't needed.
