    This pump runs our entire on-board fresh water system. It is quiet and efficient. We use an accumulator tank to reduce the number of times the pump cycles on/off. From the factory the pressure switch is set too high for use with an accumulator. It does not shut off some times. I see other reviewers complaining about this problem. The simple fix is to use a cross-head screw driver to turn the pressure adjust screw counter clockwise until the pump shuts off reliably.

    For those complaining about the pump noise it will help to not tighten the mounting screws too tight. Leave them about 1-turn above the base mounting flange. Then the pump vibration mounts can absorb the noise. If you tighten the mounting screws too tight it defeats the purpose of the vibration mounts and makes the pump noisy. If using a bolt instead of a screw then use double nuts to lock it. If done right the pump makes very little noise.

    The OEM pumps are no longer available for the water system on my Sea Ray 420. This is the replacement. It is used in tandem with a 1990 vintage pump the runs just fine. This pump is the second one that failed in a one year period. This is a Great Lakes boat, so we are not talking about very much usage and we are in a freshwater environment. The pressure switch failed in both cases and the pump does not shut off. Then it overheats and fails. The redesigned pump is not as robust as the former models and I am not very happy with the new design.

      Comments about Shurflo Aqua King Automatic Pressure Water Pumps:

      We have replaced the unit 2 times in the last 15 months and it has failed again after 30 days. Once a week I had to adjust the screw. Took a shower, did dishes, etc and the next day it was dead. Some real problems with the switch quality. Time to
      move on to a different manufacturer.

              The pressure switch on the pump failed; pump will not stop running. Instruction manual does not address pressure adjustment, but the center screw of the five Phillips head screws on the front of the pump is meant to adjust pressure. As delivered, pump would run continuously. I adjusted the pressure controlling screw and pump ran properly for a while. Now, no adjustment will help. Returning pump today.

                I easily installed this pump on my 28ft. Bayliner Ciera. I am very pleased with the water pressure with my shower and sink.The pump cycles off quickly and efficiently.It is better than the pump I previously had on the boat.

                      Comments about Aqua King Automatic Pressure Water Pumps:

                      This is definitely a small boat/low flow specific use.
                      I have an occasional use single fixture transom shower so I was not looking for high pressure, but due to the fact the water tank is approx 30 inches below the pump I am getting next to no flow. It literally trickles out of the handheld showerhead. For a small installation where the water supply is at the same level it may be sufficient for a sink but I would not recommend this for a shower.
