keep in mind if you buy a new membrane that the flow restrictor matches.
Do you know any details from before?
how long the guy had it?.
Being a sealed cannister with only 1 tube in and 1 out It's pretty hard to dry out the RO membrane.
again do you have the rating of the unit?

The guy before me said he had it for two years but just changed the first 3 filters to the unit about 2 months ago. I have the same unit as the one on

You should test the TDS of the fresh water, not the salt water.
Check what the TDS is coming out of your tap (use a very clean container).
Compare that to what comes out of the RO unit before the DI and also after the DI.
So you should have 3 TDs readings.
RO/DI doesn't just remove phosphates but other bad things in the water. Put it this way. If you had a glass of water and mixed sand in it, waited until the sand settled in the glass, then took a straw and drunk the crud on the bottom, that is your waste water.
That is why it is called waste water. It is all of the bad stuff you want removed (not just phosphates).
What water have you been using before? Just use that

Thanks for clearing up the waste water part for me. Yes I the gausge read 60 psi on the waste water discharge line after the flow adjuster. After disconnecting the connection to the di unit the water going to it was already dripping 1-2 drops/ sec which would be the 4th part of the unit. I tried opening it to see what's causing the blockage but I'm not able to pull out any filter part like I thought it would have. Seems to be a built in unit for that part. I was using my fridge water to change my tank water before this. Should I just dump my 15g make up water from the waste outlet? Even tho it is reading 0phosphate now? What would happen if I just use it.
