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?
I believe there are more RV pumps that can be used with accumulator than pumps that can't. The one you initially mentioned can't.
Small accumulator by Shurflo is smaller than their 3GPM 4008 pump and can be screwed directly to the pump, connectors are included.
Yes, it helps with cut-in frequency only. But, when a pump mounted under bed starts cycling in the night every time one of you makes a quick trip to washroom, or in a daytime when you run a trickle of water to rinse a spoon - this is when it will help. Fewer cycles, less annoying. A lot of people tried accumulators and are happy, there isn't much to say here.
