Ngemibhobho enezivalo ezivaliwe, sincoma ukuthi uthenge umbhobho kanye ne-valve yokuvala eceleni, bese uwafaka ndawonye. Ubuhle balokhu ukuthi okokuqala bashibhile kakhulu. Yize ziyizingxenye ezimbili, zibiza kakhulu uma kuqhathaniswa nombhobho onama-valve okuvala wonke. Ngaphansi, ngoba ukwakhiwa kombhobho ikakhulu kubheka umphumela wokufafaza, ngakho-ke zonke izakhiwo zangaphakathi zenzelwe ukufeza umphumela omuhle wesifutho. Uma ngabe idivayisi ye-valve yakhelwe ekugcineni kokungena kwamanzi, isakhiwo sangaphakathi sokuqala sombhobho sizobhujiswa. Umbhobho udinga ukwakhiwa kabusha, okungagcini ngokwandisa izindleko zokwakha, kepha futhi kukhuphula nezindleko zokukhiqiza. Enye inzuzo ukuthi umlomo wombhobho kanye ne-valve yokuvala ziyizingxenye ezimbili. Enye yazo ilimele futhi ingathathelwa indawo ngqo. Uma umbhobho kanye ne-valve yokuvala iklanyelwe yonke, khona-ke eyodwa yazo iyalimala, futhi zonke izingxenye zezingxenye zidinga ukushintshwa.

Uma umbhobho uqhutshwa amanzi ompompi, ungakwenza ngokuphelele lokho. Kepha uma uqhutshwa yimpompo yamanzi, ngaphambi kokufaka i-valve yokuvala kufanele ubheke ukuthi iphampu yamanzi inedivayisi yokuzwa ingcindezi. Uma kungekho divayisi yokuzwa ingcindezi, ungasicisha isitobhi Ngemuva kwe-valve, ipompo lamanzi liyaqhubeka nokugijima, okungahle kuqhume ipayipi lamanzi noma kweqe ibanga lengcindezi lepompo yamanzi, okuholele ekonakaleni kwempompo yamanzi.

Ngeminye imininingwane yezobuchwepheshe ngamabhulashi anezivalo ezivalekile, sicela ukhululeke ukuxhumana nathi.
