I am making 5 gallon brews with a 15 gallon Blichmann Boilmaker w/o the hop blocker going to a March 809-HS pump (pre boil volume is 6.85 gal.) I pump thru a Blichmann Therminator, back to the boil kettle to a bulkhead w/valve for the whirlpool.
I’m using 1/2" ID Thermoplastic tubing.
The pump is 3’ from the kettle and 12" below the kettle outlet. The distance from the pump to the chiller is 12’ and at the same elevation. The distance from the chiller to the whirlpool port on the kettle is 5’ and 18" above the chiller (whirlpool port is 6" above the outlet on the kettle)
The problem is the whirlpool is very slow, not what I would expect. Is this slowness due to the distance the wort has to be pumped back to the kettle?
