Upgrading to VS pump from Single Speed

Moved from here. Marty - TFP Mod

Been a while since I've been here and boy things look different! Came on here to look for info about upgrading from single speed pump to VS or VHP (not sure I know the difference). I have an all-Jandy system now with the RS-8 controller and iAqualink. Would I have to get a Jandy VS to work with my stuff or would a Pentair work also? I don't know if it's possible but ideal scenario is that I don't have to do any plumbing for the inlet/outlet to line up to the new pump. Any recommendations?

i have jandy I aqualink and 3 pentair VS pumps. They work fine. Its the only system Ive had so I dont know what if anything is missing ... The ONLY issue I have with the VS setup is that the freeze protect VS speeds set in Iaqualink are ignored by the pumps and when the temp goes down I manually go in and set max rpms lower to save $ then raise back after warms up ...

I’m very sure Hayward VS pumps work with the RS8 also. I empathize that last time I changed pumps I chose one (almost exclusively) that the schematics lined up perfectly with the old Sta-Rite pump I swapped out so I didn’t need to move PVC. INYOPOOLS.COM has excellent schematics on their pumps that I use. I wouldn’t recommend that as I did, as now I’m very comfortable amending pipe location and the pump itself should be what you want first.

inyo has pumps that are direct change out with single speed Jandy's. I'm getting one to change our stealth out to VS (the Century V Green 165). However I don't know if it will work with your automation but pretty sure inyo will be able to tell you. Good luck!
