staying primed basically means that the upside down U shaped bend that goes over the edge of the tank never fills up with air, otherwise the overflow won't overflow.
lol. becaue the air can only go one way hence the "one way check valve" Also air can get in your oveflow through the intake(where water goes into hole) just by suction.fish that splash, et cettera. The air will get caught at the top of the loop. So you suck the air out of loop using the check valve. check valves come with air pumps most of the time so water doesnt drip into the pump itself
muckieman,yea.
seen that thread a few times.
ah.

will try making a pvc over flow soon.
