my 300GPD is useless at the moment even when boosted it still only makes 27 29 litres an hour at 85psi 40psi before boosterd.
is there anyway you can deadin the sound of the pumps? sort of put it into a box with something to try and lower the noise..
my idea was just to run this in the day because of the noise which is what i do now with the 300GPD but running say from 9am to 6pm would only make about 240 literes
were as i was hoping the 4040 would be more enuf just to be run in the daytime.
