i have had my 4040 ro for about 6 months now and seems to be producing water really badly not a good ltr per minute ration about 1.8ltrs , its boosted with a 100 psi shurflo , can carbon a nd sediment filters cause this ???

or what could it be the battery running the pump is a 95 ah so more than enough power !

i had it plugged up to a tap and only 1/4 filled my 650 in and hour and 40 min

please help!

ok shawn make sure you have clean, fresh filters (sediment and carbon), also when was the last time you back flushed the ro?

its the pump.

the pump may be 100p.s.i., but i bet you a quid its got 1.8 LPM printed on it as well, you need somthing thats high flow as well as high pressure.

like this

(this pump is also available from machine mart  ;) )

have you even tried running it without the pump, as maybe the low flow rate of the pump could even be throttling you tap water flow ??

if it was working okay and producing good amount water

fault points towards a few options

need to change pre filters

need to spend more time cleaning  the membrain 

may have blown the presure switch in pump
