Enclosed, please find the push rod for WC flush valve from the
supplier. The reason that the flush can not be performing the proper flush
job is due to the push rod has been properly glue and fastened and it fell
off the piston mechanism which will cause the flush valve unable to flush.
However, it seems that the material shown in the picture is brass and our
push rod is somewhat different in material from the picture shown. If we
ask Thaisin to make Zn-Ni plating, it can eliminate the rust problem. The
rust problem does not cause the flush valve to not be able to flush!!
