Liberty 331 is great!
By gmonatl (from Atlanta GA) on 11/13/2011
I bought the Liberty 331 on the recommendation of a plumber doing work at my house. It is an incredible little pump. I use it to transfer water between rain barrels for irrigation and it is a workhorse! It deliver incredible power, its not too loud and it just goes and goes. I definitely recommend it to anyone needing a reliable, compact pump.

Liberty pump
By Pedro (from Hamilton On) on 7/6/2011
I bought a 331 Liberty transfer pump to pump the rainwater collected in my rainbarrels. I called a pump specialty sore in Hamilton On. Canada where I live. I was quoted a price of $260 plus HST. I found PEX Universe online and purchased the same pump for $100 less plus shipping and brokerage fees,HST etc. I still came out ahead by $60. Water rates have been rising at double the inflation rate in Hamilton for the past 7 yrs, and will continue rising. I'm getting more barrels next year so a useful pump will be an asset. I'm very pleased with my new pump
