So, what's the trick? I have a three-keggle HERMS with a single March pump. The plumbing is 1/2 inch plastic tubing running from through-mounted ball valves. On the inside, the valves go to 3/8 OD pick up tubes. There is also a 3/8 OD HEX in the HLT, which feeds the MLT. The pump is mounted couple of inches under the keggles, and has a manifold with two inputs and two outputs.
So, when I open the ball valve to the HLT to let hot H2O flow through the pump and into the MLT via the HEX, nothing happens. I'd think, at very least, gravity would cause H2O to flow from the HLT into the manifold, and thus into the pump, but nothing happens.
Any thoughts? Would it make a difference if I lower the pump even further so the keggles have more "head"? I'm stumped.
