Adding water saver piggy back RO

[Mutton Biryani]

I have a 4 chamber 75 GPD RO/DI unit. I want to add another RO in series. The only thing I can find near me is a 90 GPD piggyback unit. Can I add a 90 GPD to a 75 GPD system? I only find examples of people doing 75+75 or 90+90


Thanks for your help

I believe this is possible as long as the appropriate flow restrictor is used to guarantee the correct pressure level through the membranes. I cannot speak to which is the right size for your system.
