We have a main/bottom drain in our AG pool. Seemed like a work saver when we talked to installer about it and thought about it.
WELLLLL it does not seem to do much of anything-leaves and bugs just float by it when it the pump is on low. Even when I put the pump on high and close the skimmer line it does not do much. It will hold a leaf on it but I have to put the leaf on it otherwise it just floats on by.
I guess my question is this-how much does YOUR main drain pull? Everything else is working great!
