Umthombo ongaphandle akufanele uhlelwe kuphela esithombeni esiyinkomba. Umumo ofanayo wamanzi ungabukeka uhlanzekile endaweni eyodwa futhi ungcolile kwenye ngoba umoya, ukujula kwamanzi, ukunikezwa kwamandla kagesi, ibanga lezivakashi, kanye nezakhiwo eziseduze konke kushintsha umphumela wokugcina. Ipaki ivamise ukudinga iphethini lamanzi elithambile elilingana nezihlahla nezindlela. Isikwele esikhulu singase sidinge amajethi aphezulu kanye nokukhanya okucacile. Umnyango wehhotela ungase ukhathalele kakhulu umsindo, isikali, nokubuka kokuqala usendleleni. Lo mehluko mncane ephepheni, kodwa banquma ukuthi umthombo ulingana nesayithi ngemva kokufakwa.
Yingakho umdwebo wesayithi kufanele uhlolwe ngaphambi kokuthi uhlu lwemishini lulungiswe. Usayizi wepompo, inombolo ye-nozzle, indawo yokukhanya, umzila wekhebula, indawo yekhabhinethi yokulawula, nokufinyelela kokulungisa konke kuvela kusayithi. Ukuphakama kwamanzi nakho kudinga ukufanisa isimo somoya, noma isifutho singawela ngaphandle kwechibi. Uma iphrojekthi isendaweni ebandayo, ukugeleza kwamanzi ebusika kanye nokuvikelwa kwemishini kufanele kufakwe kusenesikhathi. Ukuhlela okuhle akuwenzi umthombo ube inkimbinkimbi; isiza isistimu ukuthi ilingane nendawo futhi yenza ukusebenza kwakamuva kubikezelwe. Futhi kunciphisa izinguquko eziphindaphindiwe zesayithi, ngoba ithimba seliyazi ukuthi amandla, ukubuyisela amanzi, kanye nezindawo zesevisi yemishini kufanele zibekwe kuphi.
