The most common reason is from a loose adjusting ring: • Check for loose adjusting ring and tighten as needed. The second, and more difficult, relates to the type of ball valve installed. Earlier production of this faucet included a vacuum breaker ball. Since then a new spray head was developed with internal check assemblies eliminating the requirement for a vacuum breaker ball. The vacuum breaker ball can be identified through the existence of two vent holes in the top of it. If the faucet has a vacuum breaker ball, there are two options: • Replace the vacuum breaker ball, part number RP12301 OR • Order new spray head (wand), part number RP32542, and new non-vacuum breaker ball, part number RP70.
