You need to have the sizing figured out and be sure there is no way a siphon can form so that you will never have an overflow from your sump onto the floor.

yeah this time the plumbing design will be different

[whitetiger61]

i know what i did wrong and wont make that mistake again

[jimsflies]

What happened, did you have a siphon form?

[whitetiger61]

i had a straight drain pipe from the bottom of the tank with a stand off pipe and didnt allow for power outages..that was my first split system and it just wasnt plumbed right

[whitetiger61]

i didnt even 90 it at the top

[jimsflies]

Not sure I completely understand, was the drain inside an overflow?

[Werdlone]

A good check valve is always a good investment. I put one on my frag tank return line and it works great. Never have to worry about a siphon. I've had issues in the past with algae growing over the anti-siphon hole and a little overflow.....Wish I put them on my display.

[whitetiger61]

i didnt have an overflow..if was just a straight standoff pipe the tank was drilled in the bottom

[Werdlone]

did the drain line leak thru the bottom tank fitting? it usually stops when it goes below the standpipe???
