• 1. Ufakelo olulula, kulula ukuyisebenzisa, ngaphandle kwezixhobo ezinokuthi zifakwe;
• 2. Uyilo oluvulekileyo noluvaliweyo lunokugquma ngokupheleleyo kwaye lutshixe isiphatho sevalvu ukunqanda ukungasebenzi kakuhle;
• 3. Yenziwe ngeplastiki yobunjineli be-ABS ephucukileyo, igqunywe ngokupheleleyo kwaye yomelele;
• 4. Ukumelana nobushushu obuphezulu, ukumelana nokugqwala, ukunyibilika, kunokusetyenziswa kwiindawo ezahlukeneyo ezinzima;
• 5. Ukumelana nokuqhekeka okugqwesileyo kunye nokumelana nokunxiba, ukukhuselwa okungcono kokhuseleko lwevalvu yesango;
• 6. Imibala eyahlukeneyo iyafumaneka ekukhethweni, engasetyenziselwa ukwahlula imibhobho ngemidiya eyahlukeneyo kwaye ingasetyenziselwa ngamasebe ahlukeneyo, okwenza kube lula ukulawula.

Ukusetyenziswa kweValve yegesi yokuvala

• 1. Vala okanye uvule iswitshi yevalve yegesi yetanki yegesi;
• 2. Fakela ibhokisi yevalve yesitshixo segesi kwisiphatho sevalvu yegesi uze udibanise;
• 3. Faka isitshixo sokhuseleko kumngxunya wokutshixa kwaye usitshixe;
• 4. Qinisekisa ukuba isiphatho sevalvu sivalwe kakuhle kwaye asinakuphinda sisebenze.
