BWT BestFlush

The BWT Bestflush valve is recommended to install after the Filter Head to run couple gallons of water as required when replacing new filter. If you have other ways to run water (such when you install to drinking water faucet), then you do not need this accessory to relief pressure buildup within the filter or water lines because the BWT BestHead and BestHead Flex has built in non-return valve.

However, it is required to install if used with any BWT water filter size X and larger as a secondary relief to the BestHead automatic filter head because in large filters the trapped pressure is higher.

Comes with washers to connect direct to the filter head.
