I'm looking at finally getting a pump for myself. I am eyeing a Little Giant 4-MD-HC. My main question is with the flow rate near 14gpm is there a problem with throttling back the flow rate using a ball valve (if I need to)? I plan on using this for pushing hot liquor (tired of lifting hot water), then whirlpooling, and cooling. My intent is to hopefully have a very good whirlpool, better than the videos I've seen using the 3-MD-HCs. I like overkill as long as overkill isn't detrimental. I hate buying something more than once so I'd like to get a little more than I need now so I can grow in the future. I currently brew 6-12 gal batches.
I have pretty much ruled out Chugger pumps, and March pumps. I've read too many gripes about priming and or failures using those pumps. I have yet to find a "my little giant doesn't prime" or my "little giant died on me in the middle of a brew". So spending a little extra for a bigger pump with a better rep for durability is right up my alley.
