for my immediate need of using the flojet system to supply water to lever operated, manual-fill boiler machine(s), i should be ok sans accumulator; if i move to a pump driven machine, i should get the accumulator. does my reasoning check out?

I have what is called a 'water heater expansion tank' inline with my flojet. It is maybe 1ft tall and 8in diameter, I have it hooked inline with guest fittings. On my 4L boiler it will usually kick the flojet on to recharge the pressure tank once every three automatic boiler fills.

Without this I was getting about 2bar of pressure shift every 1-2 seconds during a pull, with it there is no shift at all. The tank itself plus the fittings and adaptors ended up being just about $80.00 at the local Home Depot. And there was no wait for shipping.

Hope this helps.

i know i need more exercise, but that's not what i had in mind

I use a Flojet with my Conti Lever at home and when doing a gig. I have also used it to refill the reservoir on the Astra when I do a charity gig with that machine. Yes, I could plumb the Astra but that would be a hassle to redo it at home. Internal piping access rather than external.

Be careful to get one that is safe for potable (drinking) water.
I bought one on the bay and when it arrived, it stated on the box..DO NOT USE FOR POTABLE WATER.
FBN fleabayer too so I have one I can't use and no recourse.

This is a great point. There are many different types of tanks available. The one I have is an air bladder style tank that is for residential potable hot water. It is lined inside to prevent corrosion, and I am guessing that it most likely uses a specially treated rubber to withstand the pressure expansion from the hot water heater.

So, If you do not feel up to doing the research pay a bit more and get one of the little beauties like Dan posted the picture of from EPNW. They are a great company and I have ordered from them several times, including my flojet set up. Less tank ofc .
