Topic: a bit of plumbing help?

How big is the discharge pipe ?
I had started to plumb in a vintage water fountain in the shop, it was near the cleanout, so my plan was to drill/tap into the square nut portion...(to drain the excess water) ....
 Cant remember but I think there was room for a 3/4 inch pipe thread..?
 Might be a option if you have the pipe tap..

Drilling and tapping into the ductile iron or the brass cap was one of my initial ideas. I'm sure it would work, but it wouldn't look remotely to code. The way I'm going to do it will look (and act) very much code-compliant. That will help in case I do ever need to have an inspector down there.

Vames , I got this 3 1/2 - 3" bushing from the plumbing supply $20? Black iron, Thailand. the big box stores didn't have it. The counterman gave me a lecture along the lines of what Don said. Anyway I use it for my emergency sump pump temporary installation. I have a water powered sump pump to use when the 120VAC is out.

Edit:  sorry I forgot to attach the photo.

Yep -- same here. No 3 1/2 - 3 bushing at Home Despot, but a real plumbing supply place near me has them. Clearly it's not 100% code to do it, but I am preserving the clean-out access and function, so I should be fine. And it will look super pro.
