Whatsa Quiet Water Pump?

Many of the pumps I've looked at say NOT to use an accumulator. And the space is really tight, so not sure where I would even put one . . . but you're saying it will help with cut-on frequency, not with noise, right?

Most of the noise comes from the plumbing vibrating against walls and what not.
If you can isolate the water lines where ever they touch anything (pipe insulation works great) you can reduce noise dramatically.
There are also "Quiet Kits" that add more flexible lines to the input and output and allow the pump to vibrate without transferring that to the harder pipes and anything they touch.
Some even put foam or rubber pads under the pump.

Thanks. About 10 years ago I put the pump on rubber mounts and wrapped it and the plumbing from it in dense foam. That cut the noise maybe just 20% or so. Needless to say I was disappointed in my effort . . .

There are many ways to quieten the pump, depends on what is causing it. Often it is the plywood surface it is sitting on. Try putting 2" thick piece of closed-cell foam under the pump. Length and diameter of intake hose matters - the shorter and wider, the better.

My Flojet 03526 wasn't quiet. Shurflo Revolution 4008 was better.

They all make noise. Only once I saw a quiet one: 12V Inline Centrifugal Pump. Could barely hear a sound in the video. The guy tried it in the US market, went to Dragons, - big mistake :). I used to watch this show sometimes, then lost interest. Episodes are heavily edited, questions and answers are cut and mismatched to make it more exciting. Main question they always ask - How much have you made in sales already. If the number isn't big enough they are not interested. Boring.

x2. find the quitest pump you can, and do the above to further reduce noise. Most pumps now list a db level. FWIW a mid level pump isolated well can easily be quiter than a very quite pump mounted to a board with hard connection lines running against hard material.
