One only needs a length of hose slightly longer than the distance between the mounting feet on the pump with the ends of the hoses cut at a 45ļ angle, the long side being down for mounting screws of bolts. Set the pump on the first length of hose and mark the points where the mounting bolts will be. Then, drill through those points with a bit about the size of the mounting bolts using a few odd pieces if the hose, similarly drilled, as a backing inside the hose itself. Slip the mounting bolts through the pump "feet" and then through the hose and backing pieces. A little dab of Lanacoat on ones finger will allow one to position and hold first a cut washer and then a nyloc nut over the bolt ends to get the threads started after which one can use a box wrench to hold the nut while tightening the mounting bolts from above. Once the hoses are secured to the mounting feet, the long sides of the diagonally cut hose are through bolted or screwed to the deck or bulkhead where the pump is to be mounted. The hose lengths then act as a vibration dampener and will substantially reduce vibrations/noise from the pump. BTDT...

I second those navy showers- no Hollywoods on my boat.

I had a headhunter pump in my fishing boat. It is variable speed and extremely quiet...extremely expensive too.

Re: What is the quietest fresh water pump?

The quitest pump i have seen is the new variable speed pumps. They are made by a few companies Sure Flow, Jabsco and probably others. Pretty spendy but when you see how well they work you will be happy.

One just needs ensure that the waterlines have enough slack on either side of the pump to flex without damage to the connections. In addition to checking the accumulator bladder, you might also check to ensure that your pressure switch is operating properly and not activating for an unnecessarily high pressure.

FWIW...

Ah... Try turning off the pump and getting folks to rely upon a hand/foot pump at the galley sink when the yacht's away from the dock except when showering (navy showers) or rinsing dishes after washing. One (or one's child) takes a glass of water to the head to brush one's teeth, for example. (We did this with our daughter when she was small and, after we returned from an extended trip, the first morning home she walked into the kitchen, got a glass from the cupboard, filled it with water at the kitchen sink and headed for her bathroom. "Where ya going with that?" I asked. "To brush my teeth Daddy" she replied. I just smiled, "Good for You honeybee!") Those were the daze...

Re: What is the quietest fresh water pump?

It may just be the age of the pump. I replaced ours last year when the old one died and couldn't believe how much quieter it was.
