  • nice pump By ROGERWILCO357 on 9/8/2013

    Well you get what you pay for and love the quiet pump and its longevity I have had one of these for years and after switching to another tank it sat for years then I put it on again and worked like a champ ..
  • Great Pump (quiet!) By David on 2/22/2013

    I just finished installing this pump and I could not believe how quiet it is. The demo in the video do not do justice. If this pump fits your specs...get it.
