Iimbonakalo:
1. I-304 itanki yamanzi ensimbi engenasihlwa-rustless, nayo inokufunxa ubushushu obujikelezayo, ukonga amandla.
2. Itanki yamanzi yangaphandle – ingagalela amanzi ngobuqhetseba xa kungekho manzi abalekayo.
3. Uxinzelelo oluphezulu kunye nempompo yamanzi yokushisa ephezulu esetyenzisiweyo - inokupompa amanzi ashushu aphezulu.
4. I-flange ephezulu itywinwe iibhubhu zokufudumeza - ixesha elide lenkonzo, lilungele kakhulu ukucoca nokugcinwa.
iwaranti:
1. Uphando lobugcisa obuchwephesha kunye neqela lophuhliso, linokwenza ngokwezifiso i-generator yomphunga ngokweemfuno zabathengi
2. Yiba neqela leenjineli zobuchwephesha ukuyila izisombululo kubathengi ngaphandle kwentlawulo
3. Ixesha lewaranti yonyaka omnye, iminyaka emithathu emva kwenkonzo yokuthengisa, iifowuni zevidiyo nangaliphi na ixesha ukusombulula iingxaki zabathengi, kunye nokuhlolwa kwendawo, uqeqesho kunye nokugcinwa xa kuyimfuneko.
