hole location for external pump in sump

Radicaljbr · 08/31/2006, 01:44 PM

I am making my sump right now and would like to put in a hole for a future external pump.

Anyone know how high I should put this hole and what size?

Thanks

There is no set or standard height. It all depends on the pump.
You could put the hole up high enough off the bottom and have to put a pad of some sort under the pump to bring it up.

If you want a guesstimate I would say 3" off the bottom to center of hole should work. As for what size make it 1 1/2" bulkhead and plug it. 1 1/2" should be enough for anything you will need.

Cool...that will work for me. Can always adjust a little later.

Thanks

I had no way to drill a hole in my AGA 30g sump. So, I simply plumbed the pipe from the pump up and over the tank wall, then straight down. Seems to be working fine. I would guess I may have lost a GPH or two doing it this way.

if you put it too high up, you could get a flood when the pump is turned off

Just curious how you could get a flood from it being too high.
