I've been reading several of the treads on Bean Animal filtration plumbing and looked at numerous pictures but I'm still not sure of exactly where to drill the holes in my tank. The guidance seems to be that the "Main Drain" should be much than the backup drain and even lower than the emergency drain. So my question is why do all the photos seem to show all the holes in the tanks drilled at the same height?
If I want the water height to be 1" lower than the top of my tank and I use 1" PVC (my tank is only 55 gal.) how far down from the top of the tank should I drill the holes for the bulkhead fittings? From what I've seen when the bulkheads are on the side of the tank the PVC inside the tank consist of 90 degree elbows that are attached to the bulkhead fittings (either slip or threaded fittings). One elbow appears to be pointed up, I'm thinking this is the "main drain". Another elbow is pointed down, so I'm guessing this is the back up or Durso drain. The last elbow also seems to be pointed up which I guess is the emergency drain.
I've gone through several threads and photos but none of them are making sense to me. I've completed the construction part of the project and I'm at a point where I need to drill the holes for the filtration system so until I can figure out how to plumb this I can't really go forward. I don't what to have to remove the tank to drill the holes.
Any help would be greatly appreciated.
Thank you
