The control & "VS" series pump you have is no longer being made. (It hasn’t been made for well over 5 years)
Your new system includes the following items:
· New 1.5 hp Pump
· AirStreme Control and topside panel
You will change everything from the old system to what comes with the new system.
The new topside panel replaces the one on the top of the bathtub and the pump will hook up to the same plumbing as the old one.
No cutting PVC pipe to get this installed.
