My system is also 6 or 7 years old and I have a two port cell. Fear has come into my life since I found out that Jandy has sold out all of their old customer and do not make the 1400 2 port cell now so you have to change out to a 3 port. This in my case is going to require replacement of the complete ouitput plumbing system unless one of you gentlemen know where I can find a 2 port cell for the 1400? TKS in advance
