Mutu wa shawa ndi chida chofunikira chosambirira banja lililonse. Ngati madzi a m’bafa ali ang’onoang’ono, timakhala osamasuka tikamasamba.
Zopangira m'bafa ndi gawo lofunika kwambiri pa moyo wathu, koma kugwiritsa ntchito Nthawi ikatha, padzakhala mavuto akulu ndi ang'onoang'ono.
Kwenikweni banja lililonse limakhala ndi bafa, pomwe mapaipi osambira achitsulo osapanga dzimbiri ndi zida zodziwika bwino za shawa.
Ikani faucet mutachotsa zinyalala papaipi, yesetsani kuti musagwedezeke ndi zinthu zolimba pakuyika, ndipo musasiye simenti, guluu, ndi zina zotero.
Malinga ndi malo otulutsira madzi, pali mitundu itatu ikuluikulu: shawa yopopera pamwamba, shawa m'manja ndi shawa yopopera yam'mbali
Mukayika, shawa iyenera kuyesetsa kuti isamenye zinthu zolimba, ndipo musasiye simenti, guluu, ndi zina.
