Default RIMS flow control

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.

Are you referring to the recirculating, the sparge water, or the run off? For the recirculating I just run everything wide open and let it go full bore for the duration of the mash. For the sparge I open my mashtun ball valve 1/4, the sparge arm 1/4 and let the float switch control the water level. For the run off into the boil kettle I keep my boil kettle valve open 1/4 and sparge arm open 1/4 again letting the float switch control the water level in the mashtun. I try to keep my run off at 1 gallon per 5 minutes and keep the sparge water 1" above the grain bed.

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.

I use a brass gate valve from Home Depot. It gives me finer control than a 1/4 turn ball valve.

Not sure I agree, the pump never runs dry and it's magnetic driven. Besides when using silicone tubing it is suggested you don't want to restrict flow on the pressure side. The tubing isn't rated for any real type of psi. I only restrict enough to stop the grain bed from compacting too much from the suction created by the pump.

Silicone Tubing 1/2" ID x 3/4" OD

10 psi max pressure - DO NOT RESTRICT ON THE OUTPUT SIDE OR YOU WILL POP THE TUBING

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.

The March pumps are less than 10 PSI. You can restrict the output side without a problem. You do not want to restrict the input side.

I do the same thing as most people have posted, I adjust the flow with a ball valve on the out-side of the pump.
