On my old TT I installed an accumulator and it was a nice mod, but haven't looked into do it on my new 2013 Jayco. Your question has me thinking that I should check the model of pump first to see if the tank would be needed.
Cosmic, thanks for the link to the Lance forum. The 'on demand' pump on my current unit, unlike my previous one, has no shut off and start up pressure setting. ( The old unit's pump shut off at 42 lbs and came back on at 28, thus making an accumulator useful). My new one simply comes on when I open the tap and stays on until I shut it regardless of the flow, thus not requiring an accumulator. I guess if I really wanted the pump not to come on at night but still have water for a few flushes I could still install the accumulator and shut the pump of at night.
cheers and have a great day.
