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 vharafuiri 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.
Chengetedza mavharuvhu anoratidzirwa nehukuru hwekuremerwa kusiyanisa uye kudiki kuvhura uye kuvhara frequency. Kana vangove munzvimbo yakavharwa kana yakavhurika, hupenyu hwavo hwesevhisi hurefu kwazvo, uye zvikamu zvinofamba hazvidiwi kutenderera. Asi kana paine chinodiwa chekuchinja, chinofanira kuve chichichinjika, icho chakanyanya kuomarara kupfuura chinowanzoitwa mechanical movement. Mumashandisirwo mazhinji anoshanda, cheki vharafu inotemerwa kuti ishandiswe kukurumidza kuvharwa, nepo pakarepo yevhavha yekuvhara, yepakati inoyerera ichidzokera kumashure. Nekuvharwa kwevhavha disc, iyo yepakati inokurumidza kudonha kubva kune yakanyanya reverse flow velocity kusvika zero, nepo kumanikidza kunokwira nekukurumidza, ndiko kuti, chiitiko che "sando yemvura" inogona kuparadza pombi system inoitika. Dambudziko renyundo yemvura yevhavhavha yecheki inonyanya kuoneka kune yakakwirira-yekumanikidza pombi system ine akawanda mapombi akafanana. Sando yemvura imhando yekumanikidzwa kwemafungu ekuyerera kwechinguvana mupombi yekumanikidza. Iyo i hydraulic shock phenomenon inokonzerwa nekushandurwa kwe fluid velocity mukumanikidza pombi. Nheyo yemuviri mhedzisiro yekubatanidzwa kwekusagadzikana kwemvura, inertia yekufamba kwemvura uye elasticity yepombi. Kuti vadzivise njodzi yakavanzika yesando yemvura mupombi, vanhu vakatora zvimwe zvimiro zvitsva mukugadzira mavharuvhu echeki kwemakore mazhinji. Ndichiri kuvimbisa kushanda kwemavharuvhu echeki, kufambira mberi kunokurudzira kwakaitwa mukuderedza simba rekuita kwesando yemvura.
