I have gotten the max water 6 stage system. Barely any production coming out of it, it’s all going to the drain line. Any ideas on what’s going on?

Is your membrane flush valve open?

Only valve on the system is the main that I installed and one other valve in line to the faucet I have

Depending on the efficiency of the system a 4 to 1 or 3 to 1 waste to product water ratio is normal. For every 1 gallon of rodi water produced you may have 3 or 4 gallons of "waste" water.

What are the actual volumes.
5 to 1 would be pretty good.
You could also get another membrane and plumb it in parallel.

Just looked it up it’s 1:2

Is that air pocket still in your middle filter?

Good. What are you seeing with your system, actual volumes?

I got that air out after taking the picture

Just got it running about 30 mins ago, seen more in the drain line than the faucet side

According to your system doc, you should get 1 gallon of rodi and 2 gallons down the drain.

What would you suggest to fix that ratio?

 

[Pistondog]

What would you suggest to fix that ratio?

It is normal to put more down the drain than produce rodi.
Nothing to be fixed.
You might try adding another membrane in parallel with the existing one to increase output.

Understandable now. Just seen something about a pressure tank in the book that came with. are there pros to buying one and installing?

 

[Pistondog]

Only if your water pressure is low.
Some rodi systems have a pressure gauge.

I don’t have a gauge to determine that for sure but if I’m not mistaken my pressure is pretty good to the point I’m more worried it my be to much
