Most RO systems have a 1:4 ratio. You are getting a 1:1.
What does your ro membrane's manufacturer suggest?

Sorry, the 50/50 was an original guesstimation, but that is way off now that I look down the drain with a flashlight.
They don't suggest. It's Vertex, and their documentation is horrible.
As stated above, with the waste water valve off, I'm probably getting at least 2 or 3:1 waste to clean. I gather the valve was built to alleviate any guessing

Usually the systems have a flow restrictor that is not adjustable, it is matched to your membrane's g/day output and usually gives you one gal of good to 4 gal of waste. I see yours has a valve so it seems you could dial in the ratio that you want.
I don't see your auto shutoff. It must be hidden behind the canisters?
You have done a fine plumbing job.

Thanks for the kind comment.
And thanks for taking the time to look at my build to note the plumbing
It's frankly a rats nest, but I did the best considering the space constraints
The check valve is behind/between the pre-filters, as well as the raw water TDS probe, and the auto shutoff is behind the RO canister. I don't get credit for the auto shutoff location as that is where Vertex placed it, and hard as I tried, I just could not locate it any better
Concerning the shutoff;
I'm a bit dissapointed. I installed the check valve and a float. I was expecting it to totally shutoff the water. It only cuts the new/clean water flow. So unless I plumbed it wrong, I guess I won't be leaving it running 24/7. Not that I plan on it, but it would have been nice to leave it fill itself after use and not worry about wasting any more water than necessary.

The water should not continue flowing after the container is full. the auto shutoff should take care of that part. If it is not it is either defective or you have it plumbed wrong.
Three quarters of the way down the link, is a schematic (simple) that might help you. I do not have this brand of ro, just use it as a helper.

Take the 5th stage as if it was the DI then into the 45 gal drum
Delete the storage tank they have, unless you have one and attach it to the icemaker/drinking faucet
And I agree, if you are using this unit for drinking, tee off the drinking water before the DI

Thanks for the link, I'll wander off now for a bit ...

[gregzz4]

After consulting your linked schematic, and BRS's install video, I think I see the problem. I installed my check valve after the auto shutoff valve. I would have thought that it would work anywhere inline on the clean water line. But now I see that has no way of stopping the waste water {slaps forehead}
Thank you for the info.
I am off to tear it down. Wish me luck

Maybe someone else can chime in here as well but I don't think you should drink ro/di water, if you want you can dri k the water before it reaches the di phase. As long as the container isn't like an anti bacterial one then you should be fine.

Thanks for the heads up
Ya, I agree, drinking DI water is not so healthy. Besides the fact that we will not need to run the DI much with our clean city water, the plan is to only drink the RO water, and only use the DI for the fish if the raw water ever gets dirty enough, such as after a storm

[gregzz4]

The container is not anti-bacterial. It's just a plain old, used food plant drum
It contained sugar for making chocolate and I washed the bleep out of it with direct hot water from our heater, then wiped 'er down and drilled away
