The ProPulse Mushroom Valve is specifically designed to prevent water flowing out of the reservoir whilst filling.

Should a replacement mushroom valve or washer be required, please see replacement steps as follows;

1. Remove the reservoir from the ProPulse®
2. Remove the old Mushroom Valve from the reservoir and discard
3. Insert a new Mushroom Valve into the reservoir
4. Remove the rubber Washer from the underside of the tank plug hole and discard
5. Insert a new rubber Washer into the lip on the underside of the tank plug hole
6. Return the reservoir to the machine

When the mushroom valve is fitted correctly, it should lift slightly with the tension of your finger, when pressed. Be careful when changing the valves and washers, as any damage to either will cause the tank to leak. Be sure to check the valves and washers prior to each use, as they do wear through normal use and may need changing – this will help prevent possible damage to the water inlet valve
