• To prevent cavitation and accompanying water hammer within the extra-long tub spout tubes and/or shower risers of high-flow fixtures, such as garden tub valves and multi-head shower valves
• Unlike atmospheric vacuum breaker devices that can leak or spit, the Vacu-Rester’s “closed atmosphere” chamber serves as a vacuum breaker without the chance of leaks
• Recommended by Kohler Company for their highflow tub valves such as their SOK™ series fixtures

Installation For high flow tub valves with long spout tubes, install 652-AD Vacu-Rester on spout tube, in between tub valve and spout, within one foot of the tub valve. For high flow shower valves, install 652-AD Vacu-Rester on shower riser, in between shower valve and shower head, within one foot of the shower valve.
