Thanks for the response.
Any other thoughts on the placement of the pump intake and output ports on the kettle?
trying to remember the ideals from when I put mine on, I believe you ideally want the return an inch or 2 below the level where your end of boil wort level is, and want the port to be between 90 and 135 degrees away from the kettle drain. it is also recommended to have the tubing (stainless or copper ~2-3" in length) inside the kettle facing opposite directions to promote swirling/whirlpooling.
I unfortunately thought I would occasionally brew a 6 gal batch ( I do 12 gal batches) so I put the return at the 5.5gal level, but in 6 years on this system, I've done a 6G exactly zero times.
