So I'm a bit stumped on this one.
I have a march 809 high speed pump. I use it with my bottom drain HLT keggle and it primes immediately and pumps strike water to my mash tun, a square cooler on a table above the HLT.
But when I try and start recirculating through my RIMS tube, it takes a loooong time to get the pump going. It may be a lack of head pressure, as the wort has to be pumped up a my hard plumbed line to a fairly high point, thru a 1 1/2" RIMS tube, then thru a barb and into the top of my sparge arm in the mash tun.
I've found no solution other than turning the pump on and off, bleeding air with an autovent or my side bleeder valve, and just submitting to a process that can take 10 minutes or more.
But if anyone can help me solve this (even a new pump would work for me, if needed) I'd be much obliged.
Once I get the flow going I rarely have problems. I use a copper manifold with slits and place a nylon bag around it as well.
Here's a pic of the setup. I use a hose barb to connect RIMS tube to the top of the square cooler.
