Thanks Rex. Didn't realize that hardware stores sold accumulator tanks that would work on the coach.

I'm going to have to try the flex hose approach on the coach and the boat. In the latter case, the clank, clank, thump, thump used to drive me nuts and the local dealer couldn't fix it. I complained hard enough for the manufacturer to fly someone out from Florida to California. He spent a couple of days working on it, including enlarging holes where the water lines ran through bulkheads. The only positive thing he did was install a larger accumulator, which helped. But, when the pumps come on, the noise is still there. I assumed that there's some length of unsupported water line (e.g. behind the shower) that is amplifying the pump vibration/sound.

Flipping the position of the tank for different seasons - that's getting way too complex for me.
Approximately 15% of the total volume will be stored liquid. Depending on pre-charge pressure to the
accumulator, in relation to the pump turn on/off pressures, stored liquid is about 2 to 4 oz. [60-120 ml]. If
accumulator tank pre-charge exceeds pump turn on pressure, the liquid volume is reduced.
Good morning!
As you are well aware, frequent pump cycling in an RV is annoying to say
the least, and many of us are considering installing accumulator tanks.
After reviewing the manual for your 21 oz. unit, several questions have
come up. Perhaps you could answer them.
Re: the 6 gal. tank
1. Is the water contained in the bladder or is that for the charge air? The air is in one side and the water is on the other side. The bladder separate both, so is in contac (sic) with both on its respective side.
2. What is the optimal mounting position? The tank can be mounted in any position it does not have a preference.
3. What is the draw down quantity if mounted with the charge valve on
top? On the bottom? Mounted horizontally? The draw down is the same in any position approximate 1/4 of the volume before the pump turns on.
4. Is there a drain plug for winter storage, and where is it located. The accummulator does not have a valve for winter storage, however the air pressure will expelled all the liquid in the tank. Once the liquid outlet of faucet has been opened.
