How to replace the bonnet and poppet valve

1. Close the bottom valve handle and turn it to the level to close the water outlet;

2. Unscrew the small nut on the bell, and open the bell;

3. Open the plastic bonnet and remove internal debris. There should be no plastic fragments inside the device (special attention: do not remove the metal piece at the bottom of the reset device to prevent the spring under it from hurting you);

4. Replace with new bonnet and poppet valve kit and tighten by hand;

5. Place the bell on top of the metal screw, and then tighten the small nut. Be careful not to tighten it too tightly, just twist it by hand, just to fix the metal bell on the device, and keep a certain tension.

Reminder: In order to avoid replacing the bonnet and poppet valve again, if the temperature continues to be low and freezing, please cover the backflow prevention device with a blanket or heat preservation bag.
