Hey guys,
So I have a sight glass on my mash tun that no matter what seems to always empty when I’m mashing.
I use the HERMS coil method with a brew pump. I have a grain bag/false bottom combo that leaves about 3 inches of clearance for liquid to collect under the false bottom. This bottom 3inch pocket is where my sight glass bulkhead enters the kettle as well as my kettle drain bulkhead.
When I run the pump, the sight glass seems to always go dry, even though there’s plenty of liquid, saturated an inch or so above the grain. The recirculating line coming back into the mash tun is always flowing, so this leads me to believe that the pocket of liquid under the grain bed (below the false bottom) is always full.
Am I missing something? Could this be some type of Venturi effect? Any thoughts are welcome.
