    Should think about getting a tds meter, pretty cheap, if you don't already have one, lets you know your ro/di is in tip top shape

    Sounds like you're good to go!

    Mine does 1 gallon every 17 minutes, so you must have a bit more pressure then me!

    The valve that is inline between the RO filter and drain is the back pressure valve. It will not shut flow off completely, just create back pressure so it forces water through the RO filter.

    It is a good idea to flush the RO filter occasionally by opening up the valve all the way for about 30 minutes.

    Congrats on your new piece of equipment! Now go set up an auto top off!

    how do you flush the entire system?
    We opened it but not much water came out. This was when it was off

    Turn it on as normal, then open the valve up on the drain line all of the way. Rotate the valve handle so it is parallel with the valve body then let it run for 30 min. you should hear water rushing through it.

    Actually it should always be open so when you are making product water you have to have waste rejection water . and the rate is 4 gallons of water rejection water to every one gallon product water. Or if you do not run waste water all you will do is first lower the quality of the product water as when there is no rejection then it just forces more contaminates through the membrane and cut the life span of the membrane to not very long as a rule when properly cared for a membrane will last 3 to 4 yrs . But again that depends on the type and condition of source water and the rejection rates .
