Whats your tap tds?
You shouldnt be burning through resin or membranes at that tds.
Can you take a picture of your setup?
Cheap recommendation off the bat is use a flush valve not the restrictor valve they come with. Every time you fill up flip the valve for 5-15 seconds then open again will prolong the life of your membrane. What this does is flushes away calcium build up that clogs the membrane.
Are you making the ro/di water or buying it?
If you are making it, something is wrong, unless you have a unit that puts minerals back in. Like a home drinking water ro/di
The ro unit should have at least 95% rejection rate. At 41 out of the tap, that would leave you with 2 to 3 tds for the resin to remove. Resin should last a long time. Are you on well water or city water will be the next question?

good idea, I cant take a picture of my setup just because its a aquatic life 4 stage RO/DI unit. Wife makes me take it down because it ties up the laundry room sink
I don't have it setup at the moment. next time I set it up I will take a picture (most likely today or tomorrow).

Making it. I do have a very high rejection rate, takes a lot to get my RO/DI water. I have never measured it though. I am on city water. I have two theories after thinking about this a little longer. One, is that I didn't flush enough water out before using the unit. Second, is we had a runoff situation a while back right before I filtered some RO/DI water. I think one of these if not both shortened the life of my filter.

Ok theory was correct. Just tested the water coming out (after RO/DI unit) is zero TDS. The water that was in the bucket was used before for a water change and must have had just a slight residual salt leftover to make the TDS higher than what it should be. So good news cartilage isn’t exhausted !
