I have to say I'm surprised this system couldn't be easily managed using the properly placed ball valves on the pump outputs. I run a similar 3v2p single tier rig with a pair of 815PLs and control is never a problem - certainly don't need any added restriction beyond what the ball valves provide. All tubing is 1/2" Si and all camlock fittings are @Bobby_M's high-flow models...

Cheers!

Yeah I was surprised too! Because those pumps are so powerful tiny little changes with the pump outlet ball valve would cause huge changes in flow. I think it was just in that sweet spot on the ball valve where flow control just wasn't at its peak. Super happy now. I have to say too once I got the flow under control the rims system really started to get a lot happier too. I'll have to take an updated picture next time i'm brewing. I added a small sight glass to the outlet of the RIMS and ohh boy was that a great upgrade as well. I'm just super super happy with everything now this last brew day just felt like things were finally dialed in.

Also FWIW these chugger pumps are absolutely amazing. I think I did a separate post on this site, but now that i have even more time with them..... they are amazing. Far far better than the riptide but that is purely just my opinion so please don't get worked up if anyone is a die hard riptide fan haha.

What did you use for a sight glass?
 
Ss Brewtech one. Small and decent price.
