The new removable connection added below the check valve allows you to remove pump without draining the BIOFALLS Filter. You need a check valve assembly to hook up your pump to your plumbing. The check valve also prevents water from draining out of the BIOFALLS Filter and simplifies pump removal during winter or maintenance times.
