Have you flushed it recently?

What's your tap tds going into your RO?

What's your water pressure,has it dropped recently?

Do you take the hose off your DI(from the RO) for a couple of mins after first turning it on THEN take a reading?

Don’t see having a 3rd vessel will do anything 22 will burn through resin a bit but it needs a new ro
