I purchased this pump to replace my 10 year old pump which was damaged during the winter months.I needed to purchase one fitting at the local hardware store for connection to the well pipe.The pump comes in two different voltages, 110v and 220v, I purchased the 110v model, since mine is a seasonal pump which is supposed to come inside during the winter months.This pump is working fine, the preset pressure of 50 psi is more than enough for my outdoor water needs: Lawn sprinkler, garden watering, adding water to the pool and car washing to name a few.Replacement was easy, remove two bolts, disconnect the old motor lead in wires. Put the new pump on the tank, attach the bolts, connect the lead in wires and a few easy plumbing connections, I was done in about an hour.
