Move the No.1 switch to the off position to send a clean flush down the toilet.

Hi Edward, thanks for reaching out! What happens when you push the Override Button? When red light blinks that means low power, maybe check springs and connections. I suggest reaching out to our support teams at 1.855.ONE.ZURN (1.855.663.9876) or www.zurn.com/contact.

If the yellow light flashes, It means it's time to replace the batteries.
