Namuhla, ukuze kuqedwe umthelela ekusetshenzisweni kwamanzi emakhaya ekuhlinzekweni kwamanzi emadolobheni, imithethonqubo efanele yokuphakelwa kwamanzi emadolobheni eyabhalwa yizwe lethu ayivumeli amaphampu amanzi asekhaya nawokukhiqiza ukuthi afakwe ngqo kunethiwekhi yamaphayiphi kamasipala. Imishini yokuphakelwa kwamanzi yabahlali ixhunywe kunethiwekhi yamaphayiphi kamasipala ngokulandelana, futhi uhlelo lokuphakelwa kwamanzi olungenawo umfutho olubi ludinga ukusetshenziswa. Isilawuli sokugeleza kanye nethangi lokuzinzisa elingaphansi kwe-cavity kufanele kufakwe phakathi kokungena kwephampu kanye nenethiwekhi yamaphayiphi kamasipala. Isilawuli sokugeleza sihlala siqapha amaphayiphi kamasipala. Umfutho ophelele. Ngenkathi iqinisekisa ukuthi inethiwekhi yamaphayiphi kamasipala ayikhiqizi umfutho ongemuhle, ingasebenzisa futhi umfutho wokuqala wenethiwekhi yamaphayiphi kamasipala.
Uhlelo lokuphakelwa kwamanzi olungenawo umfutho olubi luthola ushintsho lokucindezela kwenethiwekhi yamapayipi okuphakelwa kwamanzi lapho ukusetshenziswa kwamanzi kushintsha ngenzwa yokucindezela ezwela kakhulu noma inkinobho yokucindezela efakwe kunethiwekhi yamapayipi okuphakelwa kwamanzi, futhi luqhubeka nokudlulisela isignali eshintshiwe kudivayisi eyamukelayo. Ngokwezimo zokusebenza ezahlukene, inani lesinxephezelo lilawulwa ngokuguquguqukayo ukuze kufezwe ibhalansi yokucindezela eguquguqukayo futhi kuqinisekiswe ukucindezela okuqhubekayo kunethiwekhi yokuphakelwa kwamanzi ukuze kuhlangatshezwane nezidingo zamanzi zomsebenzisi. Lapho amanzi ompompi kamasipala engena ethangini elilawulayo ngengcindezi ethile, umoya osethangini eliqinisa ukucindezela ukhishwa ku-vacuum eliminator, futhi i-vacuum eliminator ivalwa ngokuzenzakalelayo ngemva kokuba amanzi egcwele. Lapho amanzi ompompi engahlangabezana nezidingo zokucindezela kwamanzi kanye nomthamo wamanzi, imishini yokuphakelwa kwamanzi ihlinzeka ngamanzi ngqo kunethiwekhi yamapayipi amanzi nge-valve yokuhlola i-bypass; lapho ingcindezi yenethiwekhi yamapayipi amanzi okuphakelwa kwamanzi ingakwazi ukuhlangabezana nezidingo zamanzi, uhlelo luzosebenzisa inzwa yokucindezela, noma inkinobho yokucindezela, kanye nedivayisi yokulawula ingcindezi, enikeza isignali yepompo ukuqala ukusebenza kwephampu yamanzi.
Ngaphezu kwalokho, uma amanzi enikezwa yiphampu, uma umthamo wamanzi wenethiwekhi yamapayipi amanzi empompini umkhulu kunesilinganiso sokugeleza kwephampu, uhlelo lugcina ukuphakelwa kwamanzi okuvamile. Ngesikhathi sokusetshenziswa kwamanzi okuphezulu, uma umthamo wamanzi wenethiwekhi yamapayipi amanzi empompini ungaphansi kwesilinganiso sokugeleza kwephampu, amanzi asethangini elilawulayo angasetshenziswa njengomthombo wamanzi owengeziwe wokuphakelwa kwamanzi ngokujwayelekile. Ngalesi sikhathi, umoya ungena ethangini elilawulayo usuka ku-vacuum eliminator, okususa ingcindezi engemihle yenethiwekhi yamapayipi amanzi empompini. Ngemva kwesikhathi sokuphakama kwamanzi, uhlelo lubuyela esimweni salo esijwayelekile. Uma ukuphakelwa kwamanzi empompini kunganele noma ukuphakelwa kwamanzi enethiwekhi yamapayipi kumisiwe, okubangela ukuthi izinga lamanzi ethangini elilawulayo lehle njalo, isilawuli sezinga loketshezi sizonikeza isignali yokuvala iphampu yamanzi ukuvikela iyunithi yamapayipi amanzi. Le nqubo ijikeleza ngale ndlela, futhi ekugcineni ifeze injongo yokuphakelwa kwamanzi ngaphandle kwengcindezi engemihle.
