  1. Reverse osmosis drain

    I have a reverse osmosis that drain excess all the time. I understand the cost of clean water with a ratio of 1 gallon of filtered water to 2 to 3 gallons going to the drain, once the system is full (charger without using any water) does the drain shut off automatically or does it continue to drain all the time?
    I appreciate your comment, because if it continues to drain all the time, I will work on a way to shut it off once the system is charged.

    thank you
