A: 1. Jonga ukuba uxinzelelo lwegesi luqhelekile;
2. Jonga ukuba i-duct ye-duct ixhaphakile;
3. Jonga ukuba ngaba izinto zokhuseleko zezokhuseleko (ezinje: igeji yamanzi, igeji yoxinzelelo, ivalve yokhuseleko, njl. Njl.) Zikwimeko esebenzayo. Ukuba abayifezekisi imimiselo okanye abanalo ixesha lokuhlola, kufuneka batshintshwe ngaphambi kokuba bakhutshiwe;
4. Fumana ukuba amanzi acocekileyo kwitanki ecocekileyo yamanzi ecocekileyo idibana nemfuno yomvelisi weSteam;
5. Jonga ukuba kukho nakuphi na ukuvuza komoya kumbhobho wokubonelela ngerhasi;
6. Gcwalisa umvelisi we-steam ngamanzi, kwaye ujonge ukuba kukho ukuvuza kwamanzi kwikhava le-Manhole, ikhava yomngxunya, iivalves, njl njl. Ukuba i-bolts inokuqiniswa ngokufanelekileyo. Ukuba kukho ukuvuza, amanzi kufuneka eme ngokukhawuleza. Emva kokubeka amanzi endaweni, tshintsha inyama okanye wenze olunye unyango;
7. Emva kokuthathwa kwamanzi, xa inqanaba lamanzi liphuma kwinqanaba eliqhelekileyo le-geuge, yeka amanzi athatyathwayo, zama ukuvula ivalve yokuhambisa amanzi, kwaye ujonge ukuba ikhona na ibhloko. Emva kokumisa amanzi athatyathwayo kunye nokukhutshwa kwamanzi, inqanaba lamanzi lomvelisi weSteam kufuneka aqhubeke engaguquguquki, ukuba inqanaba lamanzi liyahamba kancinci okanye liphume, emva koko lihlengahlengise inqanaba lamanzi;
I-8. Vula i-valve ye-valin ye-clain kunye ne-steam cowlet valve, zama ukuhambisa amanzi aqokelelweyo kumbhobho weSteam, emva koko uvale ivalve yokuphuma kwe-valve kunye nevalve yokukhuphela i-valve kunye nevalve yokukhuphela ivalve kunye nevalve yokukhuphela i-valve kunye nevalve yokuphuma kwe-hamem.
9. Fumana izixhobo zokubonelela ngamanzi, inkqubo yamanzi eSoda kunye neeValve ezahlukeneyo, kunye nokulungelelanisa iiVlanga kwizikhundla ezichaziweyo.
