This is a generic replacement for the various versions of Watkins/Hot Spring/Tiger River/Hot Spot/Caldera OEM Heaters. Also for the Laing Tri-bend heater. This heater includes 2 sensors with new style 4-pin sensor plugs (2002+), sensor adapters and an auto-reset high limit.
Heater does not contain connection for a pressure switch. If you have a gray wire coming from the back or side of your heater then you have a pressure switch, and we have that version available here: Generic No Fault 4000, Pressure Switch, Watkins Hotspring Tiger River, Heater with Sensors, Low Flow, 230v, 4.0kW
Note: If you are installing this heater in a pre-2002 tub most likely you will use the included sensor adapters to convert you
