Serious plumbing question - how to connect a RO membrane drain hose under the sink

[Alexander1312]

I’m currently using an Aquatic Life under-sink water filtration system for my drinking water. My source water measures 32 TDS, and after filtration, it’s still 29 TDS—so it’s time for an upgrade.

I’d like to switch to a standard reverse osmosis (RO) system. My current setup does not appear to have a drain hose, likely because there’s no RO membrane installed.

Has anyone installed a standard RO system in a setup like mine (see photo below)? I’d appreciate any advice or insight on how this would work in my situation.

Pretty easy. Basically just poke a hole and stick the hose in. Theres a fitting you can use for it
