It is just holding the water in the tank and running it through a carbon filter prior to you getting it. The 4th stage/RO has to have the waste line open any time you are making filtered water. This is how it removes dissolved solids. Did I answer your question/s? I am not reading this whole post again.

this diagram has all water going through the di resin before going to the faucet or the tank. this is bad. i dont under stand because you should no drink di water.

have you tried contacting the manufacture?

See if this helps you. It's the online version of the manual that I used for mine. It appears to be the same / similar system to what you have. Have been up and running for weeks now and works great. My drain line is tapped into the pipe just like the picture, so is continuosly open. Nothing comes out of it except for when the tank is refilling.

Finally got an email back from their tech support. This excerpt is cut and pasted. Now, apparently this applies only to THIS particular unit and not the other types most of you have.

Waste drain has to be closed or it will not work. you should open it once every 2 or 3 months for 1/2 an hour to clean out the membrane. when you leave it open it will let water run over the membrane and flush out any residue. this will also prolong the life of the membrane.

So what do you all think?

exactly. the restrictor valve must be closed in order to gain pressure.

still a little confused about the water going through the di resin before going to the faucet. dont drink it.

I know what you're saying about not drinking it. But.....the last (6th) stage is activated carbon for taste. The directions even suggest installing a tee and running it to the icemaker (which I could easily do). But whether or not to drink di water is the subject of another discussion. Some say yes and some say no.

Anybody else have any thoughts?

ITS A RESTRICTOR "flush" VALVE. Water still travels through it when it is closed. "closed" is a bad term to use. think of it as on and off. when the flush valve is on (open), the system is flushing. when it is off (closed),ithe system is presurized.
i have heard not to drink. some may not hurt but i dont think a lot would be good. i just think its crazy for all the water to be routed throught the di resin chamber , stage 5.
