Paunosarudza uye kushandisa cheki chevhavha yezvigadzirwa, zvinodikanwa kuti uve nekunzwisisa kwakajeka kweiyo nheyo yevhavhavhavha yekutarisa kuitira kuti usarudze yakakodzera cheki valve uye kuwedzera hupenyu hwayo hwebasa. Nheyo yekushanda yecheki vharafu iri sezvinotevera: cheki valve inobvumira mvura kuti iende kune imwe nzira uye inodzivirira kuti mvura irege kuyerera shure kana kune imwe nzira. Ideal cheki mavharuvhu anofanira kutanga kuvhara kana kumanikidzwa kunodonha mupombi uye fluid kinetic simba inoderera. Kana kutungamira kwekuyerera kwemvura kunodzokera shure, cheki valve inofanira kuvharwa zvachose.
