theres your solution, just tie a weight like ceramic or clean rock with nylon ropes to the pumpmaybe you could also attach some kind of heavy weight to the pump so it can stay down. I'm thinking a big size rock tied the around the top.
Fucking pump...I got a plate and it sticks to the plate but now the plate just hangs sideways on the bottom. Would cementing the plate down really be the best option for that?
