Esi sihlalo sokufudumeza esingaphantsi komhlaba sisixhobo esiluncedo kakhulu nesilula sasekhaya, esenzelwe ngokukodwa iinkqubo zokufudumeza ezingaphantsi komhlaba. Ngokumelana nobushushu okugqwesileyo kunye nokugqwala, sinokuzinza kwaye sihlale ixesha elide sisetyenziswa. Inkxaso yenzelwe ukusebenza ngokugqibeleleyo nenkqubo yokufudumeza engaphantsi komhlaba kwaye ingasetyenziselwa ukufaka nokulungisa umbhobho wokufudumeza ongaphantsi komhlaba ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yokufudumeza umgangatho. I-bracket isebenzisa uyilo lwemodyuli, olunokudityaniswa ngokukhululekileyo kwaye lufakwe ngokweemfuno zokwenyani, kwaye lufanelekile kakhulu kwiintlobo ezahlukeneyo zasekhaya kunye noyilo lwesithuba. Ukufakelwa kwe-bracket kulula kwaye kuyakhawuleza, akufuneki zixhobo ezongezelelweyo okanye ubuchule bobuchwephesha. Lungisa nje iibhloko zenkxaso ngokobungakanani obufunekayo kunye nemilo, kwaye uziqinise kumgangatho. Ibhloko nganye ye-bracket ixhotyiswe ngeebholiti kunye neenati ezihlengahlengiswayo ukwenza inkqubo yokufaka izinzile kwaye ikhuselekile. Le bracket yokufudumeza umgangatho ineempawu ezibalaseleyo kwaye inokuhlangabezana neemfuno zabasebenzisi beenkqubo zokufudumeza umgangatho. Okokuqala, inozinzo oluhle kwaye inokuqinisekisa ukufakwa ngokuthe nkqo nangokuthe tye kombhobho wokufudumeza umgangatho ukuze kuthintelwe ukuvuza nokungaphumeleli kwamanzi.

Umsebenzi ophambili wesibiyeli somsasazi wamanzi okufudumeza umgangatho kukulungisa imveliso yomsasazi wamanzi ukuqinisekisa ukuba ayiwi okanye ayiguquki ngenxa yamandla angaphandle afana nokungcangcazela kunye noxinzelelo. Uzinzo kunye nokuqina kwesibiyeli kunokukhusela ngokufanelekileyo ukuthembeka kwemveliso yomsasazi wamanzi kwaye kwandise ubomi bayo benkonzo. Kwangaxeshanye, isibiyeli sikwadlala indima esisigxina kwimveliso, ukuze indawo yomsasazi wamanzi kwinkqubo yokufudumeza umgangatho ihlale izinzile ukuqinisekisa ukusasazwa kobushushu okufanayo.
