In what appears to be a cruel twist of events, I have discovered that 1 of the check valves on my 2 returns is leaking! This is probably why I was thinking the flow wasn't as strong as it could be. After a quick replacement, I've had to open the pump valve all the way up now and dial the return down because it's crazy fast. And now, we're back to crazy *** loud! I'm ready to go buy a canister at this point lol.
