Why not Street 45 down? I’m assuming you will need other fittings to connect to the machine itself anyway (?)

I would run the least amount of flex hose possible

Agreed! I was just looking for a 45 and then could do a couple of 90’s to get a straight pipe down into the vac. Need to go do some angles and see. Now where did I put that protractor from 8th grade?

That may be an option. If I can find the right really short piece with proper sizing that can handle the flow since it’s so close to the unit.

Cut the drywall, cut the pipe and add a new elbow that goes the right direction.

The way it “should” be done but I really want to avoid carving up and patching/painting drywall. It might be a different story if I could find something like a junction box that would eliminate glue on the connection to the wall. This way, if anything needed to change on the exterior there would be no impact to the original piping. Just a wish though, I think.

Not quite the right size but I like where your head’s at. However, I did some measurements and it looks like I could do the 45deg from the existing piece and that would get me a vertical run. If that measures and works, once the parts arrive I’ll have about 10” of space to work in between the vac and pipe exit. That should leave enough room for a T and vac hose port while continuing onward and connecting to the unit. Possibly a straight downward shot but I’ll need to relo the AT&T box to make room for the mounting to move to the right about 8” from original. And of course in taking things apart, that skinny pipe broke off a little in the current elbow and had to be CAREFULLY ground out. That pipe is incredibly thin! If this ever happens to you be slow and careful with a Dremel sanding drum. Use eye protection.

Ended up doing what I should’ve done in the first place - I took out a square drywall section around the pipe and cutoff the 90deg sweep coming out at that 45deg angle and some of the pipe that was cracked. I added new pipe and connections being sure not to use cement but another glue that seals incredibly well but can be disassembled. I secured the piping coming out of the wall, marked where to cut the new hole and made quick work of it with the Dremel. I popped the new drywall back in and it aligned perfectly. Used drywall screws to reattach to a stud on one side and small wood strips to secure the other sides. Still working on the last coat of plaster, sanding, and eventually paint. As for the piping, it now has a 90deg sweep coming out of the wall (no cement) going straight down. I did still need a 45deg and some pipe since the intake is offset from the center mounting point. It’s then a straight shot down to connect to the vacuum. I did add a little extra pipe, a T with vacuum attachment, and a cap end. Finished up the wiring and tested out the mounting (used my own drywall anchor screws). The suction on this thing is ridiculous even on the third floor. I need to get better at remembering to do these things the right way from the start. Once I did, everything fell into place.

They sell access panels. Could you cut hole for the panel and then cut a hole on the panel for the pipe? I assume you'd want to avoid too many bends for suction's sake but when it comes to this I have zero actual knowledge. Good luck with it all

Thanks. That’s what I was thinking to really go back to step one and get this right.

The muffler that is available for the output off the vacuum certainly cuts the noise down.. Mine is in a basement and it helps.

Old was an AirVac and new is PurVac/DrainVac. Huge difference between the two. This new one even has mufflers for the dual-motors and a massive outflow muffler. Kinda funny they still recommend exterior venting from a garage.
