    It is 90GPD, pressure is 60psi. Once it fills before the weekend I am good. I have been looking at adding a second membrane, will most likely do it sooner rather than later no that I have a much bigger tank.

    Ok good.
    Sine you have a larger tank now add a booster pump - it will save lots of money in a long term in terms of filters/waste water.

    Mine runs at 100 PSI with a booster pump-

    60 PSI will be fine for dual 90 GPD membranes. I'm running twin 150's on that psi level with no issues. Now if the pressure regularly dips below 45 then there will be issues with proper filtering and such, so it's something you would have to monitor and add a booster if it does. For me I usually just run my RO in the evenings after the wife and kids have gone to bed so there is nothing else that can pull the psi down.

    I did the same. Changed the membrane to 150GPD and added second 150GPD unit and changed the flow restrictor with addition of a buster pump. I making about 400 gallons a day. If you need s hand let me know. I love close to you.

    60 PSI is an acceptable range but not good long term for the life of the filters - plus takes much longer to produce water.

    Imagine water coming out of regular water hose versus pressure washer hooked up to the water hose. Not sure if this is a good analogy.

    I plan to get a booster pump in the not too distant future. There are other things I need to get before that.

    I'll probably be adding one after the Disney trip when I have some spare money to put towards the tank again.
