Sensor Valve Location
For the greatest effect, the valve should be located at a faucet with the greatest piping
distance from the hot water heater. If your home has a branched hot water line, more than
one Sensor Valve may be necessary. Additional Sensor Valve kits can be found at some
retail locations as well as Watts Premier website at www.wattspremier.com or by calling toll
free at (800) 752-5582.
NOTE: Do not use Teon tape or pipe dope on the Sensor Valve threads.
