Hot Tub Compatible With Watkins Spas Air Check Valve DIY70289
Hot Tub Replacement Part compatible With Watkins Spas Air Check Valve, fits Hot Spring Models 70289. Air check valve fits Hot Spring all 1993-2001 Models, fits Tiger River all 1997-2000 and fits Hot Spot spa all 1997-2002 models. This check valve is located in the equipment compartment under the bartop. Its primary function is to prevent water from back flowing into the equipment compartment should a hydrotherapy jet become obstructed (like when a guest sticks their finger in the jet). Sometimes this check valve can make a loud vibrating noise as the silicone diaphragm ages behaving like a reed on a flute.
This is for a Single Air Check Valve
Compatible with Watkins fits Hot Spring Models
Note: These check valves age at the same rate. It is best to replace all of them at the same time if budget allows
