Amanothi ngokusetshenziswa okupholile

(1) Lapho into epholile isetshenziswa, ivalvu yokukhipha umoya entanjeni yokupholisa kufanele ivulwe ukuze kukhishwe umoya, futhi ivalwe ngemva kokuba amanzi ebonakala ukuvimbela ukuvaleka komoya ekuphazamiseni umphumela wokupholisa.
(2) Uma into epholile ivaliwe ukuze kushanelwe ulayini, misa amanzi okupholisa bese uvula ivalve yokukhipha amanzi okupholisa ngesikhathi esifanayo ukugwema ukunqwabelana kwengcindezi kanye nokulimala kwempahla.
(3) Lapho ulungisa izinga lokushisa likawoyela ngemva kokupholisa, ivalve yokuphuma kwamanzi okupholisa kufanele ilawulwe kuqala. Ngenxa yokuthi ukusetshenziswa kwe-valve yokungena ukulawula umthamo wamanzi kungasindisa amanzi abandayo, kuzobangela ukujikeleza okufushane noma ukunciphisa ukugeleza kwamanzi endaweni epholile, okuholela ekushiseni phezulu nokubanda phansi, kuthinte umphumela wokushintshanisa ukushisa. Ngakho-ke, akufanelekile ukusebenzisa isilawuli se-inlet.
