Having a pump on the system sounds great ,I would say the few extra rands were well spent.My water boy unit was so slow.I suppose we get what we pay for.
absolutly incorrect.
all these size r.o.units have a 50gpd membranes in them. that means they make up to 190 litres in 24 hours if the temp outsiside is 25 degrees and if your incomming water pressure is 4bar. that is there ideal running requirements.
if temp goes up......production increases slightly and vise versa
if pressure is low.....production is low
normal municiple water pressure is 4-5 bar......some people only get 2 bar......some people get 12 bar.
if your r.o.unit runs very slow......its not because you bought a "cheap" waterboy unit.....its cheap because i try to help marine aquarists out......
do you know that the membrane alone in that units is a filmtech membrane and costs R400
your unit must be running slow for the above reasons or the membrane or check valve has a blokage.
if its due to pressure then you can add a pump onto the inlet system which we supply
i suggest you call me on 0828793943 and we can troubleshoot and have you running at full production asap.:yeahdude:
we sell r.o.units with pumps , but generally only people who live on farms, small holdings etc etc that have water gravity fed into there houses use these.
the units with pumps will just take the incomming water pressure and boost it to 4bar so that the machine can produce its capacity of 190 litres per 24 hours.
if you want more water.....then you need a bigger membrane and if you need alot more water....then you need a bigger machine.
hope this helps
