hi
WE HAVE A 640LTR TANK. MY WATER PRESSURE IS 20PSI!
FITTED A 12V BOOSTER PUMP THIS TOOK THE PSI TO AROUND 80.
WE THINK THAT WE ARE MAKING 1LTR OF PURE WATER IN 2 MINUTES (ALTHOUGH I'M NO EXPERT BECAUSE IVE ONLY BEEN WFP SINCE FEB 2005)
I TEND TO PLUG IN AND FILL UP WHEN I GET HOME AND LEAVE OVERNIGHT. I HAVE NEVER RAN OUT OF WATER AND I USE WFP LOADS.
I DON'T THINK THAT YOU ARE DOING TO BAD 1/2 FULL IN 12 HOURS AS WE ARE DOING 640LTR IN APPROX 23 HOURS.
LIKE I SAY I'M NO EXPERT BUT HOPE THIS HELPS
TOM
