So how do you guys control the flow of wort in a RIMS? Do you restrict the flow with a valve or control the speed of the pump with something like a dimmer switch or a PWM? Thanks!
I restrict the flow coming out of the MLT with a ball valve.
You never want to restrict flow to your pump. (I'm assuming your pump is immediately downstream of your MLT.)
Put a ball valve on the outlet of your pump, restrict the flow there. It's relatively easy to control.
Wait... Wait... You do not restrict the flow "after the pump" you restrict the flow with an output valve ON the pump. NO tubing is then subjected to pressures....
10 psi max pressure - DO NOT RESTRICT ON THE OUTPUT SIDE OR YOU WILL POP THE TUBING

The pumps cavitate rather easily, you'll destroy the pump head if it runs dry for too long. Email March if you don't believe me

See posts 17 and 20 from Walter at March pumps.
Inlet side... Walter said not to restrict the inlet side. You restrict the outlet side.
Think about siphoning: to reduce the flow, you pinch the end where the water is coming out, if you pinch the other end it won't be able to siphon properly.
March pumps work excellent for RIMS.
