We would like to convert to a diaphragm type fresh water pump. We are looking two options right now. Shurflo Aqua King II 4.0 gpm (55 PSI sealed switch, shutoff at 3.8 bar, ) and Seaflo Series 54 5.0 gpm (adjustable switch).
1. Is there another pump you have experience with that you would recommend?
2. Given the old FEIT/AMFA pump was 15/30, should I even consider the Aqua King with set cutoff PSI of 55?
