Avoid buying the other's junk. My 1st wayne pump lasted 15 years!!! Used daily all summer long, 125 gallons pumped a day, I tried others and they didn't make 2 weeks. The wiring is heavy duty, transferring max voltage. Spend the extra money and eliminate the problems off the cheap garbage.
The pump did not pump a gallon of water before it ate up the impellers. All directions were followed but to no avail. This is a cheap piece of junk and the only purpose I can find for the pump is filler for a dumpster,
