well,
4yrs after the rebuilt - OK, after getting MiToS back in the water only today I managed to sort out the accumulator, how's that then?
I had a crappy and V.NOISY diaphragm pump with a pressostat for the fresh water circuit with a brand new 8lt accumulator tank (not a ss shine marine item, just a normal blue one from the plumbing store).
Fitted as I should (accumulator v.close to the pump and after the pump)
Thing is water supply was always pulsating and as soon as you'd open a tap the annoying pump noise was there.
TBH I kind of liked the sound, as it was an indication that someone was "wasting" water
I'd mentally count and get more and more stressed/angry the longer I'd count...
but now with a decent 100lph watermaker, I don't really mind and I rather not have this on my ears/mind and be more relaxed.
So, bought a CR special Gianneschi pump, brilliant thing too bloody expensive though on the normal market and after a bit of fettling was put in service (I'll keep the annoying diaphragm one as spare on board)
First issue was setting it up kick in and out through the two nuts, took me some time to get the grips with this system, but got there in the end (must have wasted 20+ lt to get there...)
So now pump kicks in at 1.3bar, stops at 2.2bar or so.
However, accumulator didn't do much (well anything tbh!)
So took it out, got it to a petrol station noticed it was at 4bar
dropped it down to 2, back on the boat, started sort of doing something (not much though...)
Got a car foot pump with a gauge (v.rough one though) and started emptying the tank, went down to 1bar and for the first time I have working system.
Gauge on the Gianneschi shows 2.2 all taps closed, open one, pressure slowly drops to 1.3 THEN pump kicks in (say galley tap will run for 10-12secs before pump starts) and depending on the demand, as soon as I turn off all taps pump will stop from 2 to 10secs.
When I'm bored, I'll try dropping the pressure more and measure how much water I can extract from the tap before the pump kicks in (should be close to 4lt if the tank is 8 - but I guess you never reach that)
Very impressed, thought I'd share as I'm pretty sure there must be more idiots like me just fitting an accumulator and expecting it to work...
cheers
