Menene wasu matakai don warware matsalar P2749?

Mataki na asali # 1

Idan kun bincika wannan lambar, zan ɗauka cewa kun riga kun duba matakin ruwan watsawa. Idan ba haka ba, fara da wannan. Tabbatar cewa ruwan yana da tsabta kuma an cika shi da kyau. Da zarar ruwan yayi kyau, kuna buƙatar nemo firikwensin saurin juyawa. Sau da yawa ana sanya waɗannan na'urori masu auna sigina kai tsaye a kan gidan watsawa.

Hakanan kuna iya samun damar firikwensin daga ƙarƙashin murfin, wannan na iya haɗawa da cire wani sashi kamar mai tsabtace iska da akwati, baka daban, wayoyi, da sauransu don samun dama. Tabbatar cewa firikwensin da mai haɗa haɗin suna cikin kyakkyawan yanayin kuma an haɗa su sosai.

TAMBAYA: Kona ATF (ruwan watsawa ta atomatik) wanda ke wari kamar sabon ruwa ana buƙata, don haka kar a ji tsoron yin cikakken sabis na watsawa tare da duk sabbin matattara, gaskets, da ruwa.
