My sparge is usually good by at the absolute most, 45 minutes. I'd really like to drain out of the bottom valve of my mash, down to the floor, then pump back up to a holding tank I heat at 168 which will then drain back down and spray the mash pot. That means that I can not pump too fast or I would have to turn it on and off a bunch which means unplugging that unit. I would much rather have a variable control on the pump and I won't be pumping higher than about 4 to 5 feet.
This is similar to what I do for the mashout, step mashes (rarely), or if I'm low on the mash temp. Instead of a reservoir, I pump through my chiller coil that is now being used as a heat exchanger. As in, it is sitting in my HLT full of hot water. To regulate flow, I have a ball valve on the outlet side of the pump. This does not damage these mag drive pumps.
