I have not taken the week off. I just have trouble beating a dead horse. You have not paid attention to my browbeating, and still use definatly, which BTW is definitely wrong :D . Remember the old i before e thing guys. It is weird, NOT wierd. I could go on, but I am getting a reputation.
BTW Jonathan, I was asking how you regulate inflow versus outflow. If your siphons are faster than your return pump you will have water on the floor. The reverse is that you will have an empty sump if your return pump is too fast. I like CPR 's method of skimming the surface of the water. That way they kill two birds with one stone.
