I would like some help as well please, I have low water pressure so I have fitted a booster pump but this has made hardly any difference to the amount of water produced , I know its not the pump because I sent the first one back thinking it was faulty but the second one is just the same, so the problem must be with the filter, its an ro-man 100gpd with an 100gpd upgrade and its about 1year old, I flush it regularly but its only making about 200litres a day.
