I didn't leave off the overflow PVC, I just didn't drill the vent hole in it ...... that way it acts as a siphon and drains the bottles and the PVC ...... tight now it fills and drains about every 80 seconds, I'm thinking as I add more length, this will stretch out farther and farther. I've got an oversized pump ..... I can't find the box ..... I must have burned it, but I think it's 350gph ..... as far as pics, I'll have to study up on that and figure out how to do that with Linux ..... I'm not the geek type, I'm just a userOriginally Posted by JeffW
