Hi,

After changing filters in the reverse osmosis system, how long does it
take for the tank to be fully charged?

Is it normal to see the water in the return line (clear plastic line)
flow swiftly into the drain as the tank is charging?

Thanks,

Jeff M



The water should come out the drain continuously as it makes water, but
I'm not sure what you mean by "swiftly". If it appears to come out at
incoming line pressure, make sure you're not missing a filter gasket. As
far as how long it takes to recharge the tank, you need to know the rating
o the membrane, for example: 25gpd (gallons per day). Figure roughly 1/2
the rating for actual production. If your water pressure is very low or
very cold, it can be as little as 1/3 of the rating. The rating is
determined at a lab controlled temp and pressure, and of course, that is
not reality, but gives you a relative value. Since your tank probably
holds a little over two gallons of water, it takes about 4 hours to charge
using a 25gpd membrane. Keep in mind these are rough estimates.
