TDS Meter reading...thoughts?

i would be worried about if your carbon blocks are exhausted and chlorine is being removed, also not sure if houston uses chloramine(need a filter for that). i think all units are basically the same housing wise, but the filters are the key factor. as with everything you get what you pay for, i try to buy the best performing filter for each stage. i run filters from brs or buckeye and have been very happy with their performance. i change out sediment and carbon every six months, it also helps to have pressure gage before the ro membrane so if pressure drops you know its time to change the stages before. also having a dual tds helps, that way you can see whats going in and out of DI stage, again once you start seeing numbers creep up you can figure out when its time to change them.

the only time I had readings like that was when my RO membrane was shot.
I doubt your carbon filters are your problem.
It's either RO membrane or DI resin IMO

In order to figure out the problem more precisely, you will need to make some more readings. TDS of tap and post RO TDS (before DI stage(s)). If permeate TDS is high then go ahead and make a brine measurement while you are at it. Do it before doves this weekend

Also, make sure your pressure is correct for your RO membrane. If it's too high, you could have ruptured it.

Max operating pressure on a Filmtec 75 gpd membrane for instance is 300 psi - so chances of someone overpressurizing a membrane are remote...

Did the original posted get the situation squared away?
