What's your "Go to" water pump.
I ran my pump dry for a while, and it was just 2.8 GPM to begin with, so I want to replace it with something with a little more umphh. I looked at numerous pumps on Amazon, which will fill the bill, but this one doesn't last, this one is great, but it's noisy, you catch my drift. What's your recommendation?

I just replaced mine with a 3.5gpm sure flo. It has rubber mounts and I can only hear it run if the coach is completely quiet inside, and at that, it is faint.

The pump that marrys up best with your old pump and water lines. If you have to add all kinds of shims, reducers, ect you are asking for more problems down the road. Higher GPM's is a bonus. As previously suggested Shurflo 3.5 should do the trick.

Bought this one as a spare, https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Very similar the one in our Airstream which always worked great. Key to keeping them quiet is flex hoses. don’t connect directly to PEX or it will be noisy.

A lot of reading, this is the most reliable pump out there. A little more money but a lot more reliability and parts are available. Shurflo 4048153e75 Electric Water Pump

There are several good quality pumps out there now, especially from the boating side. Do yourself a favor and get a variable speed pump, they're quieter and smoother. I've been using the FloJet VSP since 2010 on three different coaches.

You can find many threads on making a pump quieter. Hoses instead of to pex mentioned. Surge tank. Rubber isolators. I liked the DIY isolator a couple members made of using a heater hose to mount pump to. They sell rubber isolators but hose is more like a suspension.
My mid grade pump is only mounted with small stock rubbers to rock solid floor of wet bay and has about 2gal bladder tank . There a short rubber hose where it probably froze due to small amount of water settled in polyB pipe to fresh tank. It's nearly silent.
I would like to make bypass or swivels to remove the bladder tank for winterizing. But not high on repair, maintain and upgrade list. With aquahot, bladder tank, maniblock piping system, washer dryer and stand alone mini freezer icemaker, I go through nearly 5gals of the good non alcohol antifreeze. Plus I'd rather waste a gallon than freeze a pipe. Near Chicago coldest I remember -26f I was working in plant that night.

I replaced the 21 year old Shur Flo pump on my coach last year (it was leaking from the seals) with one of these DC brushless motor pumps from Amazon https://www.amazon.com/gp/product/B09KRS5BKX/ I have mixed feelings about it, the supplied threaded fittings have the thread tapers cut backwards so they don't seal, however I was able to get a different brand of adapters (same coupler used by Flojet Triplex pumps) for under $10 so that was an easy fix, other than that it seems to work and make good pressure, though it does not cut off smoothly, instead it stutters a number of times as it reaches target pressure.

[QUOTE=153stars;6460028I would like to make bypass or swivels to remove the bladder tank for winterizing.[/QUOTE]
I put a shut off valve in the line from the T to the bladder tank.
When I winterize I open the low point drains and let everything empty out. Then shut the valve to the bladder tank, I figure there's water still in it but it's like the water heater and fresh water tank, so little water and so much volume it won't matter if it freezes.

Thanks, guys. I think I'll go with this one
https://www.amazon.com/gp/product/B0...NDYKT29B&psc=1
I was tempted to try this one, because of the extra GPM and pressure, but it had 15% 1&2 star reviews.
https://www.amazon.com/Kohree-3-5GPM...9878G1J2&psc=1
I think I'll play it safe with the Shurflo.

Ike if you are also using an accumulator try cranking the bypass pressure up a bit. This worked well with our Shurflow bypass pump in combination with using an accumulator tank.
