I had an Amarine Made pump almost identical to this one, and it worked great, for awhile. The pump, just like this one pushes out a lot of water and the pressure is excellent (requiring the use of a 40psi regulator on my travel trailer to use this pump. The big difference is in the pressure switch. This pump has a much larger pressure switch to turn the pump on/off on demand than the Amarine Made pump. The switch on the Amarine Made pump failed after only a few days of use while boon docking. This isn't uncommon as even SeaFlo users have reported the same issue with the look-a-like version of the Amarine Made pump. However, only SeaFlo offers this pump with a better switch. I'm going one step further and adding in a 30 amp relay switch, so the 12v SeaFlo switch will activate a 30 amp relay which will turn the pump on and off as needed. This'll ensure that the switch on the pump will last a very long time since it'll have only mA instead of 8 to 17 amps going through it. The pump is a bit loud but it's inside of a shed at my camp site so I don't hear it. If I were to place it in my RV, I would box it with hard Styrofoam to reduce the sound when the pump runs. The only drawback I have with the SeaFlo pump over the Amarine Made pump is that the Amarine Made pump has removable in/out nozzles. I can swap screw type for push on hose type nozzles. The SeaFlo doesn't offer this and has fixed screw on type connectors. I'll have to build adapters as needed. Overall though the pump does what it's supposed to do and does it much better than the Amarine Made (which died due to pressure switch failure), and smaller pumps that I've tried to use. I like the output of this pump.
