Accumulator, silencing hoses, or both?
The noise from our fresh water pump seems to come and go based on how the Pex lines end up shifting after particularly rough road days. I've installed foam pipe insulation and tried to secure water li...

I mounted an accumulator tank under my bathroom sink. It was a simple matter of getting a T to connect to the 2.5 gallon accumulator tank (I used a dual outlet cut off valve with a couple of pipe nipples just because it was cheapest along with a couple of section of 1/2 inch to 1/2 inch hose to extend to and from the faucet). Some people will tell you the accumulator must be closer to the pump to effect the sound, but in my experience even having the accumulator probably 7-8 line feet away from the pump it made things much quieter.
There is a scharader valve on the tank and it must be recharged with air from time to time if air leaks out, but that is no more difficult than maintaining air in tires. Exact optimum pressure will depend on your pressurizing pump,but 25-30 psi when the pump is turned off and pressure bled from the system should be in the right ballpark for most people, it is better to have too low of accumulator tank pressure than too high, the optimal amount depends on the pump model and its pressure switch. Having the pressure in the accumulator tank a little low as long as it is not zero pressure will just reduce its capacity a bit, having it too high will keep it from working at all.
