Right its the same with mine, but you'll still get some. Once the water level drops below the overflow box the water stops. The bigger the tank (witch has more surface area) the more water is going to come down. Believe me I know I've ran a few over before lol so you'll need something big enough that can still hold all that water plus whatever might come down. Make sure if you make a overflow box its big enough aswell the more water you push to the tank the more the box has got to get down. I screwed up there and had to put on another.
I compared the pond pumps to sump pumps and they was still cheaper and gave a lot more gph. Just a heads up
You sound like you have done a ton of research or have had them before. So ill stop giving you things to keep on/in mind, don't want to make ya mad.
Just thought you would like to see how I did it.
Nah, not making me mad in the slightest, I like double checking with real people that what I've read is accurate Research only goes so far compared to real experience, and this is my first sump so I want to make sure I do it right.
I'll check into sump pumps, I didn't realize they were actually cheaper! Thanks!
