Just curious on why you have a valve on the inlet and outlet of the pump. Is it just a design preference?

I need those valves to keep the pump primed when I'm switching hoses. Once I've started a mash, I don't turn off the pump until the sparging is complete. This pump is prone to having its impeller seizing on its shaft if its turned off with high sugar content wort (typical wort). Then you won't be able to get the motor and impeller spinning again. Copious cursing and screaming ensues while you take apart the pump head to free the impeller. Its not a good scene for anyone. Having those valves is a good thing.

PS: shutting both valves while the pump is spinning does not hurt the pump.
