Iinkcukacha zeValve! Nantsi yonke into ongayazi malunga nee-Angle valves
Ukuba i-valve ye-Angle iyavuza, kwaye kufunyenwe ukuba i-core ye-Angle valve yaphukile, inokutshintsha kuphela i-Angle valve. Ukuba kufunyaniswe ukuba indawo yokuvuza yevalve yeAngle ikujongano, phinda usonge ibhanti lemathiriyeli ekrwada kwaye uliqinise. Kubomi bokwenene, ivalve engunxantathu kwisifudumezi samanzi yagqabhuka nje ukuba indlu entsha yabanye abanini igqityiwe, nto leyo eyabangela ukuba imibhobho ivuze kwaye ikhukulise umgangatho, ikhabhinethi yeTV, i-wardrobe, njl. Oku kwenzeka, ngokuqhelekileyo ngenxa yokuba umgangatho we i-Angle valve ayibangelwa. Ke ngoko, kwinkqubo yokuhombisa ikhaya, kufuneka sinikele ingqalelo ekukhetheni umgangatho olungileyo Ivalve ye-Angle musa ukuba nepeni elumkileyo kunye neponti yobudenge.
