variable speeds, and suspect they were also problematic.
After reading through RV forums
about horror stories with the Shurflo failures, all those guys seem to change over to Remco Aquajet variable speed pumps, and the complaints stop with this one: Remco 55AQUAJET-ARV Aquajet RV Variable Speed Water Pump
Hard to find anyone having a problem with it at all - everyone seems happy.
These don't seem to appear at all in the marine
market, but they are big in other markets. Don't know why they are not "marine", unless they are rebranded under a different name for that market.
So we just bought one and will be installing it when we return to the boat in a month. Hope it works and lasts because did I mention that we REALLY like the variable speed pumps?
Just an update -
This pump is installed now and working well. It is VERY quiet and provides high pressure. I had to turn down the cutoff pressure adjustment quite a bit because it comes preset at 75psi, which caused it to constantly hunt on our system - most likely due to the length of our water system and the compressible parts
therein. Easy to do - there is a hex key adjustment on it.
So far we are very happy with it. It provides constant flow no matter what volume is asked of it. The flow never goes up and down and up and down, etc while using single
faucets at any flow rate or multiple faucets simultaneously (I can shower
while Michele is washing
dishes and neither of us notice any difference in flow as we cut the water on and off).
There is absolutely nothing on this pump that makes it "non-marine" (except the lower price). The pump body is plastic, all screws and bolts are stainless, the motor
but has a thick epoxy paint
coating on it, all connections are plastic, etc. I can't find any physical difference between it and the Shurflow or Flojet pumps we have on board.
I cannot measure any standby power draw on it at all using a clamp-on ammeter. I think it may use its pressure switch to cut power in and out of its computer. When a faucet is opened, the pump does not come on immediately, but comes on at full speed after the pressure drops enough to trigger the pressure switch (~1-2sec), then drops in speed for 1sec, then runs at a continuous speed appropriate for the demand needed.
If there is indeed a standby power draw, it is so low as to be negligible (<<1A/day).
