Description
This complete set includes (2) 1 1/2″ Spigot X 1 1/2″ Slip Gate Slice Valves plus (2) 1 1/2 X 2″ Heater Unions with Gaskets. Each valve features a 1 1/2″ spigot connection that accepts pipe or fittings measuring approximately 1 7/8″ OD on one end, while the opposite slip side fits inside 1 1/2″ fittings. The assembly slips into the 1 1/2″ inlet of the heater union and bonds to a 2″ heater flange fitting (approximately 3″ OD) using both adhesive and screws. Important: This configuration differs from pump union slice valves – verify your application carefully. If your spa connects to the heater using 1 1/2″ plumbing with 2″ heater split nut threads, you’ve found the correct components. These isolation valves allow convenient heater or pump maintenance without completely draining your spa water.
