Ray,
Is your accumulator factory or home brewed?
If home brewed - does it need to be charge regularly?

Not sure what the schrader valve is for, doesn't say how much pressure to put in
it or anything.

I can't figure out how a Schrader valve can be useful either.
Granted, it could be used to pre-charge the system -- while it's
sealed. But, the first time a faucet is allowed to run without the
pump turned on, and allowed to run dry, that charge will escape. The
only "pre-charge" that will be persistent is that built up by the
water rising in the cylinder -- which should be mounted vertically
with the water in/outlet at the bottom.
A 2-gallon well pump accumulator, with internal bladder, fit very
nicely under one of the sofas in our 23' & works Great.

Of course, that would only happen without a bladder.
Here is what the Shurflo people say in their manual:
RV/MARINE APPLICATIONS The accumulator contributes to longer pump life, less noise, less amperage draw, and reduced water pulsation. The most efficient use of the accumulator occurs with the pre-charge set at the SAME pressure as the pump’s pressure switch “turn on” setting. Typically, a 40 psi [2.7 bar] pump will turn on at 20 psi[1.4 bar]. Therefore, the pre-charge should also be 20 psi [1.4 bar]. The pre-charge MUST be set in a“static” condition (pump off and at least one water fixture opened). 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.

I was thinking of using about three feet of 4" PVC since I have it on hand
and locating it over the propane tank. Put an elbow where the Schrader
valve is with a three inch rise to it and then put the Schrader valve on the
top of the elbow - or run a line near the tank water fill.
Still thinking...

Was wondering if anyone has had the same experience with the non-bladder
home made system. Of course the Schrader fill valve could be remotely
located in the propane cabinet.

If your home-made (or any other non-bladder) accumulator was plumbed in to the right spot*, it could double as a winterizing blow out.
I like modifications that have double uses!
* The "right spot" would be close to the the pump or the city water connection. (or both)
