Query: 1700 gallons per hour-not!

Bought this pump to drain a 4000 gallon pool. Thought we would have it drained in 2 1/2 hours at the most. 5 hours later it is not even half drained! No way this pump could do 1700 gallons per hour! Should have looked for a 2500 gallon per hour. Very disappointed!
