That's what I thought but then I saw this performance curve where 80 gpm is about in the middle of the 1.5 HP curve.

The reason is that I have an in-floor cleaning system. The IC40 Installation and User's Guide states: For flow rates over 80 gpm you must use a bypass loop (as shown below) for best chlorine production. Installations with flow rates over 80 gpm include those that have in-floor cleaning...

Pentair support let me know that this bypass loop would be absolutely required for any warranty claims I might have in the future. The filter is that far away to accommodate the bypass. No room for it going straight back to the wall.

Never mind - I found it: Amazon.com: 2 PACK -CMP Hi-Temp Union 2" inch 2MIP x 2" inch PVC Whisperflo & Intelliflo - 2 PACK: Garden & Outdoor

Great suggestion! From your post I just realized, after 11 years now, that the inflow and outflow are actually threaded on my WhisperFlo. Do you have a link to a pump union handy? I did a qucik search and did not find anything obvious.

Yeah, that does make sense. My pump is nearing end-of-life and that will make it easier to change it out if needed. Thanks.

This is probably what I am going with:

Thanks. A good suggestion. The PVC union was legacy from the existing piping. But if I'm going to redo it, I should redo it in a better way if possible:

The sensor for the IC40 is on the bottom. I am counting the PVC union as straight pipe.

This is my design for re-plumbing that I need to do. I am looking for comments on any mistakes I’ve made, suggestions for improvement or validation that this is a viable design. Since I have an in-floor cleaning system, I need to replumb to add a bypass loop for my Pentair IC40 SCG. This is...
