RO/DI plumbing shematic needed

[TW]

Can anyone point me to a link for a Four stage RO/DI unit schematic. I
can't seem to get it back together properly. My system has a drinking
water kit with holding tank, faucet, and seperate pressure guage, and a
Kent shutoff valve attached to the end of the RO unit housing.
I appreciate any help

Hi Todd, I don't have a schematic, but this is the lay-out:

Water line to Prefilter (white cartridge) to Carbon (black cartridge) to RO
(thin tube at top) to DI (color changing cartridge to shut off valve.

There is an ASOV (auto shut off valve) at the top behind the RO membrane that
has 4 tubes feeding into it. This is the layout:

Tubing (red) coming from the Carbon goes in the "IN" marked portion of the
ASOV. Red tubing comes from the "OUT" marked portion and feeds into the RO
membrane. Two outlets lead out of the RO at the opposite end, one blue tube and
one black tube. The black is waste water. The blue goes into the ASOV and then
another blue tube comes out the opposite side of the ASOV and goes to the DI
cartridge.

Have fun making sense of my words. :)

Thanks for the reply. I have a different kind of shutoff valve. I got
rid of the kind that you have. The ones with 4 ports, 2in and 2 out.
They kept failing on me so I gave up. I switched to the kind made by
kent marine.

It is a solenoid type valve. I'm just not sure which lines go on the
ends of the valve. The outlet on the side of the valve is attached to
my RO in. There are lines attached to both ends and this where I get
into trouble.I don't know what lines are supposed to go into these two
inlets.

This is a WAG on my part, but according to that page you linked, it appears that
unit goes on the waste line.

What did that kit cost? How many outlets are on the SOK?

Since you are converting from one to another, you'll either need to get a
coupling to join two pieces or you'll have to replace the two shorter tubes for
one longer one. Again, that is another WAG since I can't see it. (Wild Ass
Guess).
