How to remove the cuonnector from the Alka Spring, Ultra or sediment filter housing ?
To disconnect the connector on the under-sink unit, you can use a slim butter knife or a slim screwdriver. Insert the blade between the chassis of the filter and the O-ring of the connector. By wedging the connector off in this manner, you will be able to push off the O-ring, which is the component that locks the connector in place. This method will help you safely and effectively disconnect the connector.
