OK thats how i did it but the the pressure is over 15 and clean water is coming out of the hose. So basically the water goes from the pool thru the hose and out and i loose water ;(. So you are saying that the water should go thru the pump the to the big container and the out thru the hose but i think mine goes thrue the pump the straight to the hose. It doesnt go thru the big conatiner. Thats what i think.
