Accumulator installation

I am planning on much dry camping this fall so I bought a 2 gal accumulator to reduce pump cycles and soften pump start-ups. No installation instructions came with it, not even an online reference. But they are all basically alike and I did enough research to figure it out....mostly. It won't fit in the space where my pump is, in the bathroom, but it will fit nicely under the kitchen cabinet. So, I have 3 questions. 1. Will locating it so far from the pump reduce its effectiveness? 2. The under-sink plumbing is convoluted and hard to figure out. I did however discover that the water heater input line, when disconnected, spurts a lot of water when I turn on the pump. Seems that's a good tie-in point. Correct or not? 3. Should I make life simple and run single line to the accumulator or run two lines that route water through it?

    The objective is to accumulate pressure, right ?

    You can't compress water.....so there needs to be some air trapped in there.

    I don't see how either one of yours will do that with the inlet at the top. Seems like they would eventually fill completely with water and become ineffective.

    Maybe they have a sealed bladder inside ??

    IF this is going to function like a "pressure tank" on a well system, then you can NOT run the water "through" it.

    In general, it needs to be mounted so that the water connection is made at or near the bottom of the tank......so the necessary air pressure pocket can form at the top.
  • anywhere in the cold system is fine. I have one in my trailer and one in my house installed at the furthest point in the garage.

    I have the small Shureflow in the trailer and it works for me....second one I have installed in my RVs.
