Another overflow question ??

You should be able to handle about 1000 gallons per hour or so no problem. Go the same size as the bulkhead as you won't get any added flow without a bigger bulkhead as well. Allow a couple inches above your stand pipe that way if the return is a little too much the water can rise a little above the top of the stand pipe(creating some extra pressure and increasing the flow to match the return). don't glue your standpipe, play with it a bit and see what works. :?

I think maybe the pipe size confused some people. :?:

1" will do about 800 gallons per hour.

1.5" will do about 1600 gallons per hour.
