Accumulator and silencing kit as well as some personal mods to help with the noise are on my shorter mod list. Just haven't gotten there yet. We really don't use it a lot; mostly just when we're on the road, or if DW needs water while she's setting up inside before I have the city water connected or after I have the city water disconnected during tear-down. If we were boondocking and/or using the pump all the time, it would be much higher priority on the mod list.
