As can be seen in the pic above and the title, I'm stuck on how to connect this last piece of drain pipe to the floor drain. I have a sch. 40 socket Wye which has not been cemented yet to the floor drain pipe. Everything else you see has been primed/cemented, except the Y screen filter, which had male threaded ends. The local inspector said anything less than 4" did not require purple primer, and although he recommends it generally, he said he wouldn't care if I used one-step clear cement (contains both primer and cement.) The Y-screen was a last-second addition that I thought may be beneficial to make sure the corrugated french drain it goes into didn't get debris potentially inside of it. I'm not entirely sure it is necessary, but after the effort I expended putting in a french drain properly, I didn't want to risk it clogging internally from random debris somehow.
I had originally dry-fitted all of this and had it all connected great from source to the drain. As I'm sure is apparent, I'm not a plumber and didn't realize how much "shrinkage" I would have after the pipes were primed and cemented, which caused my great alignment and connections to be slightly off. From some tests I've run, it seems like my dry-fitting only gets the pipes seated about 3/4", with the fully primed/cemented seated pipe going in about 1 3/8". Now that it has all been cemented up to this point, and this last angle slightly changed, I don't have the "give" (in the hole in the wall that the pipe goes through) to raise the pipe enough to seat a cemented pipe in the 45 degree fitting, and then push it back downwards into the Wye. It also seems like it might create a slight upward slope (on the other side of the wall) if I cut out a little from the top of the hole in the wall on both sides in order to lift the pipe higher.
Is the only real answer to cut more material from the hole in the wall on both sides, so that the pipe can be raised a little, in order to be able to fit a cemented pipe in both ends? Or is there some trick of the trade on how to do this that my n00b ass just simply doesn't know?
The floor drain was originally intended to be for a "mud sink", but has now be repurposed to handle output from a sump pump. The slope seen in the pic is not the slope throughout the rest of the drain; the rest is approximately 1/4" per foot. Even though it will be under pressure via the sump pump, I sloped it anyways just to be redundant. This last 4' or so of pipe got extra sloped when I cemented the fitting right before what you see at a slightly steeper angle than I had when I dry-fitted it, resulting in this steep drop.
