I've looked around at Lowe's and Home Depot and they go from 2" to 4" PVC. I want to create an eel cave system and I only want to do it once. Is there somewhere local that carries 2.5 - 3" PVC? Schedule 40 is fine. I'd prefer 2.5". I can try Ferguson. I looked online, it's an extra $20 just to ship one 48" pipe, but if I have to do that, I will.
