Intended for installation during initial construction but can be added after the fact
This is intended for install during initial construction but, with creativity, can be installed after the fact. The biggest issue I had, aside from the creative piping to tie it in, was getting the fill valve tight enough not to leak in the canister. And I'm a licensed plumber.

It works
I installed this while renovating my pool. It was a little technical but easy to in stall and set up. I am really happy with it's reliability. It has worked with issues for just over 18 months.
