Review: Reliable Pumps - Replaced a Salamander Shower Pump - 2 Salamander pumps replaced in 3 years. Have purchased a Grundfos pump in the past, 8 year later it is still going strong. Hope this new one last as long.
Review: I would recommend this simply for peace of mind - The pump works splendidly. It is powerful and quiet. I cannot speak about longevity as yet as I have only had it a few weeks. I guess it got past the early-life failure deadline. My last pump had plastic input ports that broke clean-off hence my purchase of a pump with brass input ports. I would recommend this simply for peace of mind.
