After i turn the lever to flush toilet, the tank will refill then auto flush again. Sometimes until 2-4 times, waste lots water..
Whats wrong with my wc ?

Knn .. everyone having fun teasing hah.. hahaha... !
So many shampoo bottles on the cover, lazy to touch it. But it seems to have season, sometimes ok, then sometimes keep on flushing. Its a lever type.
Thx for the tip guys, at least i know can be repaired diy easily.
