     After the delay valve button is pressed, it cannot be returned to cause the water to be closed. What should I do?

     The specific reasons for this phenomenon are as follows: 1. The small groove of the inner cavity of the delay sleeve is clogged, but the possibility is relatively small; 2. The delay rubber and the push rod stop glue deform and deteriorate, causing rubber and pushing The friction of the inner wall of the rod or the delay sleeve is increased, and when the friction is greater than the spring and hydraulic force that contribute to its reset, it cannot be reset.
