Xa kufikwa kwiinkqubo zemibhobho yamanzi,ivalvu yokujongas zizinto ezibalulekileyo. Zenzelwe ukulawula indlela ukuhamba kolwelo oluhamba ngayo kwipayipi kwaye zithintele ukubuya okanye ukubuya kwe-back-siphonage. Eli nqaku liza kwazisa imigaqo esisiseko, iintlobo, kunye nokusetyenziswa kweevalvu zokujonga.
Umgaqo osisiseko weivalvu yokujongakukusebenzisa intshukumo yediski yevalvu ukulawula indlela oluhamba ngayo ulwelo. Idiski yevalvu idla ngokuyilwa ukuba ivuleke kwicala lokuhamba kolwelo oluqhelekileyo kwaye ivale ngokukhawuleza xa kusenzeka ukubuya kolwelo. Olu yilo luthintela ulwelo ukuba lungabuyeli umva kwaye lukhusela ukuthembeka kwenkqubo yemibhobho.
Iivalvu zokujonga ziza ngeentlobo ezahlukeneyo, kwaye ezona zixhaphakileyo ziquka ibholaiivalvu zokujonga, iivalvu zokujonga ukujika, kunye neevalvu zokuhlola ukuphakamisa. Iivalvu zokujonga ibhola zisebenzisa idiski yevalvu engqukuva evala umahluko woxinzelelo lolwelo. Iivalvu zokujonga ukujika zinediski yevalvu ejikelezayo enokuvuleka okanye ivale ngokuzenzekelayo ukulawula icala lokuhamba. Iivalvu zokujonga ukuphakamisa zisebenzisa idiski yevalvu eshukumayo efakwe kumbhobho ukuze kufezekiswe ulawulo lwecala lokuhamba.
Iivalvu zokujonga zisetyenziswa kakhulu kwiindawo ezininzi. Kwiinkqubo zokubonelela ngamanzi,iivalvu zokujongazisetyenziselwa ukuthintela ukubuya kwamanzi nokugcina uzinzo loxinzelelo lwamanzi. Kwishishini leekhemikhali, iivalvu zokujonga zithintela ukubuya kweekhemikhali eziyingozi kwimibhobho, ngaloo ndlela zikhusela ukhuseleko lwezixhobo kunye nabasebenzi. Kwishishini leoyile negesi, iivalvu zokujonga zisetyenziselwa ukuthintela ukubuya kweoyile negesi nokugcina ukusebenza okuzinzileyo kweenkqubo zemibhobho. Ukongeza, iivalvu zokujonga zisetyenziswa kakhulu kunyango lwelindle, kwiinkqubo zokucima umlilo, kwiinkqubo zomoya opholileyo, nakwezinye iindawo.
Ukuqinisekisa ukusebenza kakuhle kweevalvu zokukhangela, kufuneka ulondolozo kunye nokuhlolwa rhoqo. Iidiski zeevalvu kunye nezitywino kufuneka zicocwe kwaye zitshintshwe rhoqo ukuqinisekisa ukusebenza kakuhle. Ngaphezu koko, ukukhethwa kunye nendawo yokufakelwa kweevalvu zokukhangela kufuneka kuqwalaselwe ngononophelo ngokusekelwe kwiimfuno ezithile zesicelo.
Ukuqukumbela, iivalvu zokujonga zidlala indima ebalulekileyo kwiinkqubo zemibhobho ngokulawula indlela yokuhamba kolwelo kunye nokuthintela ukubuya kwamanzi. Ngokukhetha uhlobo olufanelekileyo lwevalvu yokujonga, ukuqinisekisa ukufakwa okufanelekileyo, kunye nokwenza ulondolozo rhoqo, ukhuseleko kunye nokusebenza okuzinzileyo kwenkqubo yemibhobho kunokuqinisekiswa.
