3 questions, 1) is there any risk of CO2 added in the drain ports of the pump causing cavitation damage in the pump? 2) if installation complexity isn’t a problem, would you still recommend injecting at the drain ports? 3) I have 2 pumps, a “filter” pump that is the workhorse pushing water through filter, UV sanitizer, heater, wall returns, and when active floor cleaner jets. The other “water feature” pump runs at 1100 rpm 24/7 to overflow a zero edge spa. Which flow stream should I introduce CO2 to?

Great questions. Injecting the small amounts of CO2 into the pump is what allows it to get completely absorbed - it doesn't create bubbles or air pockets. Since it is completely absorbed, that means it is extremely effective at adjusting the pH. You would connect it to the main "filter" or "circulation" pump, not a booster or other pump used for water features.
