I got it when I was going to move house, I bought it originally as a transfer pump for a static system, but used it at my current home as a booster pump, I then bought a second pump to run as a booster pump, the sale then fell through on the house I was buying, so am left with 2 pumps, as I have my ro on the van where I live now, I only need 1 pump, so I am selling this one.
