  • Hot Tub Watkins Hot Springs Spa & Caldera Spa Ozone Check Valve HTCP1044101 OEM

    Hot Tub Replacement Part Watkins Hot Springs Spa & Caldera Spa Ozone Check Valve HTCP1044101 OEM. This ozone check valve is the OEM replacement for the Freshwater I, II & III ozone units. Over time an ozonator check valve will breakdown under the harsh conditions of ozone. Our newly designed (7-2013) OEM check valves have a special diaphragm (Viton) that enables them to last longer than rubber diaphragm check valves. The purpose of this check valve is to prevent water from draining out of your spa through the ozonator in the event that your spa looses power. A power loss will stop the Silentflo 5000 circulation pump from operating and therefore stop the suction (Venturi effect) at the injector. Since the ozonator is installed below the surface of the water, the only thing stopping the back flow of spa water through the ozonator is this check valve. In addition to this check valve it is also recommended to loop the 1/4" ozone tubing high (just under the spas bar top) to help keep water from constant contact with the check valve during a power failure or if you spa is in "Summer Mode". If your ozone bubbles have stopped bubbling up through the drain of your Hot Spring, Tiger River or Limelight spa, then the check valve may have failed.
