Which CSV125 would work with my system?

Thanks, Carey. I will consult with the old lady and see what she thinks. Hopefully I'll be ordering soon.

I do have a question: If I order the CSV125 and have it with a 30/50 switch but then later go to a 40/60 switch, would I need to change anything on the CSV?

You would need to change from a CSV12540-1 to a CSV12550-1.  They are not adjustable.  You can use the CSV1A and set it anywhere between 15 PSI and 150 PSI.

Oops. The 1A is the one I intended to say but I typed the wrong thing. So, there is a way to adjust the 1A? (sorry for delayed response-- been busy)

[Cary Austin]

Yes. Tightening the bolt on the CSV1A will increase the pressure from 15 PSI to as much as 150 PSI.  Just need to be running about 3 GPM when adjusting.

[zannej]

So, will it be preset to the right setting for a 30/50 though? Or would I have to specify that when ordering somehow?

[Cary Austin]

The CSV1A can be preset to 40 PSI if you ask for that in the notes when ordering one.  Or you can turn on a shower and adjust the bolt until it stays at 40 PSI.
