I am not sure this is a good time to do a review as I have only used this pump randomly and on twice for a few hours. It is the Back up tank pump for the RV and I am always on city water so never need to use it unless I don't have city water for some reason. I would definately get the 5 chamber and 5 gallons a minute next time though. This pump vibrates from cavitation a lot. I got the lower GPM thinking it will make me save water and it does, but the vibration from the cavitation could be better just by getting the higher version of the pump. Just skip the 4 Chamber as I had a leaking problem with that one.
