I just scored a little giant 4-MDX-SC pump for next to nothing on craigslist. It's whisper quiet and can easily pump ~20 gpm, but it's only rated for 150F. I'm confident it will be fine for my pre-boil pump needs, but I'd really like to use a pump for whirlpooling and chilling too. Does anyone know if the pump heads from the various LG-4-series pumps are interchangeable? It seems like they would be, and I'd really like to get a ryton head (HC model) for this pump if I can find one at a reasonable price.
I also just got some 1/2" camlocks and silicone tubing for x-mas. The intake and discharge are both 1", and I'm wondering if there are any issues with narrowing everything down to 1/2"? It seemed to work fine during a quick test, but I haven't really been able to put it through the paces yet.
Thanks in advance-
