Bought a used basketball hoop on a metal pole for 25 bucks. Looks like it’s in pretty decent shape, and it’s for my 11 year old son whose interest in sports is pretty flighty, so I’m not too concerned about longevity or amazing quality. I would, however, like to install it correctly.
I’ve checked online and found varying reports of the correct way to do this, and my father-in-law, who will be assisting me, has his own ideas (see below), therefore I come to you with the following observations and questions:
The diameter of the pole is 3.5". It already has concrete in the bottom of it from the old installation. Should I knock that out, or does it make sense to leave it in? How big a hole should I dig? I’ve seen from 1’x1’ wide x2’ deep all the way up to 2’x2’x4’ deep, with the most common instruction being 2x2x2 (would like to keep the amount of concrete I have to mix to a minimum).
My FIL seems to think it would be a good idea to use a PVC pipe, so that the pole can be easily (?) dropped in, but this sounds iffy to me. Would a PVC pipe with a nominal diameter of 3.5" fit around the pole, or would I have to go with something larger? (and if I go larger, then the pole won’t be stable or level unless I pack around the extra space) There doesn’t seem to be any way to test the fit unless I buy the pipe. Not sure if the idea is to set the pole in the pvc in the concrete all at the same time, or just set the pvc, then insert the pole, but either way it just doesn’t sound right to me.
Most of the instructions online just say to put the pole in the wet concrete, level it a few times an hour until the concrete sets. This also sounds weird to me, because it seems like it would be very hard to keep a pole standing upright enough in wet concrete to keep it level. Especially since part of the hoop assembly is still attached to the top of it, so it’s not perfectly balanced.
Any insight on this would be appreciated, and if the mods would like to move this to the Game Room or anywhere else, have at it–it’s the weekend and I’ll be lucky to get any kind of a response here.
