Hello all, as the title states i have no suction in brine mode. i replaced the what came with the rotor disc seal kit and cleaned the venturi, and i'm able to suck brine through the float. when in brine mode i removed the hose from the venturi to check if it was sucking and it still isn't. in fact it has a dribble of water coming from it, the venturi, not the hose. when it switches from brine to rinse i get suction for a couple of seconds and then it stops. i don't have any external leaks that i've found. the disc looks clean and unscarred, i'm stumped. any help would be greatly appreciated. thanks, Chris
