there must be - kinda "snap" sound when its in, only after then put a rest of tank together - this knowledge cast me 30 ml my fav juice, aha. Snap is there for sure.Okay, now, I'm not changing my review of how it hits, but the cover for the deck slides down at the slightest provocation. This causes leaking if it doesn't stay upright. I can't get it to stay up in the "locked" position at all.

I will go pick up some preen weed killer to keep the little uglies from coming back
