        Comments about MQ3-45 Pressure Boosting Pump (230V):

        I have 2 of these at my ranch house. One for home and other for stock. They have done well until some grand kids left the water on and ran storage tank dry. The pump locked up and will not turn even though it is supposed to have automatic protection against running dry. The new one had instructions on how to manually unfreeze one. I have not tried that yet, so it may still be good. Other than that, very simple and easy to install.

        Works great with my rainwater catchment system at a price that beats the competition. Plus, customer service quickly resolved a screw up with my initial order and got the right pump to me asap.

            It cannot. This pump requires 230-volt, single phase power.
