2 bars is enough (mark on the doc) or can I increase it a little?
what will the difference be if i increase it?
please

and if j increases in 32 what would be the changes in pressure?

This behavior does not seem abnormal to me, as said Gaston; the output flow is such that it is equal to the pump flow and that the very low buffer storage capacity is absorbed as soon as the sampling tap is opened.

Increasing the regulating pressure does not seem to me of any use, as for increasing the diameter of the suction pipe, that can have an influence on the flow of the pump by reducing the losses in load (frictions) but does not act directly on pressure.

As long as bib2210 does not want to tell us if its speed is, according to him, sufficient or not, we will not be able to help it ...

bib2210 So do a potting (flow measurement in a jump with timing) and you compare to the flow given by the manual for the pressure that you read ... this is the only way to see if you have a functioning problem. .or if everything is normal!

Normally the pressure on a booster when the pump is running never drops to 0.0 ... even if nothing is connected. And if the pressure is 0.0 and you have a hose connected as in the photo (which creates a little pressure drop) then the flow rate at the outlet of this hose will be theoretically zero ...

Exact, but given the accuracy of the measuring instrument, there may not be much difference between 0.2 and 0.0 ...

And if bib2210 also told us what it intends to supply with this booster :?:

He said it: garden watering ...

Now if it only rises the water over 2 to 3 m it is normal for the pressure to drop to 0.2 or 0.3 bar + measurement error as you say, we are at 0.0 ...

I will not respond to this subject until he has told us about the flow precisely, because I have the impression that we are going in circles there ... :|

Same impression, that the output flow is higher than that which the pump can provide.

Yes, but it can go from the open pipe (pressure ~ 0) to drip (flow ~ 0) ...

thank you for your interest
don't worry I will keep you "au jus" tomorrow, by doing the flow test
the only thing that bothers me is why the flow to the pressure gauge collapsed when I opened the valve
passing from 3 bars with an extraordinary jet then in the 5 sec which followed, a mano collapse from 2 to 0 bars
but i do the promised test
tonight it's concert in nimes (chemical brothers)
