Hot Tub Compatible with Watkins Spas Air Check Valve, fits Hot Spring Grandee, '89-'93 HTCP70326 

• This is for a Single Air Check Valve
• Hot Tub Compatible with Watkins Spas
• Fits Hot Spring Grandee, '89-'93 
• This one way check valve fits Hot Spring Grandee from 1989-1993 for the Jet Stream Jet air intake.
• All jets compatible with Hot Spring have both an air and water mixture. If someone put their finger in a jet nozzle and restricted the water flow, water could then back flow through the air lines and pour into the equipment compartment. This could short out equipment and/or siphon out the entire spa. This check valve is located inside the equipment compartment, up high under the bar top. Replace if it's old and cracked or if it has been leaking.
• There are two of these check valves that fits Grandee, one for each Jet Stream Jet.
