I have to write a review on this pump after I am initiating my second return. I thought the first one was a fluke. The first pump had an on/off pressure set pretty high and the pump never turned off. The more recent one does not come on automatically until the pressure is very low and now after a few days of operation it does not want to shut off either, just run down the battery bank. It is important to note that I verified with the manufacturer that the 55 series pump does not have and adjustable pressure switch as it is sometimes advertised to have.

    absolutely the best on demand pump
    This 110v in line on demand liquid transfer pump is the best one on the market right now in my opinion. I have used many other transfer pumps. But this pump by far exceeds the others I have used, and the price is also a lot better then others as well. Its simple you open the valve and the pump comes on. When You close the valve the pump shuts off. It delivers 3gpm of liquid. This pump is also rated to trasfer other liquids then just water. Its rated to transfer liquid fertilizers as well as many other similar consistency liquids, wheres as the other transfer pumps are soley rated for clean water transer only. This was a big selling point for me as I am using it to transfer liquid fertilizers and this was the only one rated for that in its price range,

      This pump works perfect for water plants from a rain barrel. As soon as you close the valve on hose the pump stops. Perfect!

      Seems to be working good as an alternate to my original North Star pump for my 25 gal sprayer tank. I did have to monkey with the small allen screw behind the rubber cap in order to limit the pressure to 60psi. It wouldn't seem to shut off originally. The manual didn't address this.
