Have you checked your water's ph? Low ph eats up resin.

135-167 is the low/high if tested my tap water. I am few miles from Lake Michigan. TDS drops to 2 (before DI) at first and if I run it long enough it drops to 1 or even 0 (before DI) but usually have to stop and flush and restart for it to get that low.
If you flush your membrane before and after each use your DI resin should last longer, ever see how much TDS creep you get from starting and stopping? Mine goes from 2 up to 65 TDS in a matter of minutes...flush every time if your able but not everyone is setup to do that.

I've installed ro systems around the country and anything bellow 200 I would consider good. It's not too often you see it bellow 100 and like many have posted it's common to see it above 400 in some places, mainly drier areas where it's supplied by an aqueduct, well or certain rivers. These tds levels don't mean much for health, it's mostly calcium and magnesium salts, imagine a river flowing 1000 miles over limestone, some dissolves. These days there is more concern with pollution/runoff contamination but it's a minimal risk. The main thing it means to us is less efficient ro function and higher running costs. You said your sediment clogged up, how old is your house? How about the neighborhood you live in? I'm thinking old plumbing. I've installed things in old buildings and the rust in the pipes clogs the pre filters pretty quick.

mine runs 310-320. but i have no problems going thru prefilters or resin. actually i have had a spare bag of resin for over 6 months. thinking i would need it. we make 100ish gallons a month for over 20 months. booster pump made all the difference.

Mine is 450-475 and nitrate tests at about 50ppm! (API test) We have some well water here. I told the city water people about the nitrate and they tested and said it's lower than that, they claim the home test kits overstate the nitrate (not sure if I believe them).

Going back to the origional posting of the sediment filter being black/clogged, the TDS is not going to impact your sediment filter. The TDS is what is dissolved and the sediment filter removes what is not dissolved. Usually they will go hand in hand but not always. Are you by chance running your carbon block before your sediment filter? The carbon dust should get trapped by the sediment, turning it black. Usually it's run sediment then carbon, keeping the carbon pores cleaner and therefore removing more chlorine long term.

I don't think I've seen lower than 600, and 800-900 is pretty common. My water is usually pH ~7.8 coming out of the faucet, extremely hard water.

320-340 out the tap but is super hard and leaves water stains on everything with out a softner ro drops it to about 1 and DI last for ever.
