Quick waste drain question

Hello,

I’m a DIYer completing the plumbing in my basement. Thankfully most of the waste pipes were already plumbed in. I’ve tried my best to get a basic understanding of UPC.

In double checking my work ahead of getting my plumbing inspection I realized I used a medium 90 coming off of my shower 2” p trap and not a long sweep (horizontal to horizontal). I feel like an idiot because it’s glued in with the shower pipe the perfect height to later install the shower pan.

Tried extensive searching to find an answer, so I’m sorry if this is obvious. Is a medium sweep 90 acceptable from horizontal to horizontal or should I cut it and start over?

thanks in advance for help,
Chris

No, a medium sweep 90 can not be used as a drainage fitting in the H to H position. Luckily if you cut the pipe right at the face of the hubs, a Long Sweep 90 will glue right to those pipe ends left behind... I've been there done that.

Minor point, but for ABS, Charlotte's catalog says a quarter bend has an offset of 2-1/4", a long sweep 90 has an offset of 3-1/4", and a 2" hub has a depth of 3/4". So would you want to cut it 1/4" from the face of the hub? (3-1/4" - 2-1/4" - 3/4") That would be a bit easier to do anyway.

Regardless, one could hold up the new long sweep 90 underneath the quarter bend and lined up with the pipes, mark the hub faces on the pipes, and then cut the pipes 3/4" (or maybe a hair less?) from those marks, for the hub depth.

Cheers, Wayne

Hey, wait a minute.

This is awkward, but...
