check valve

Refers to a careful inspection of the positioning/operation of a new/replacement one-way flow-stopper to make sure it's being installed in the correct "direction".

Zero was too stupid/unaware/forgetful to perform a "check valve" detail when hooking up the plumbing for the Camp Swampy mess hall, and so now there are geysers squirtiin' up all over da camp, but no water coming out in any of the kitchen-faucets --- just something more for Sarge to bellow about.
