Here's a pic Randal. See the blue RO line going from the tee to the water
shutoff valve. The blue line going left out of the picture from the tee is going
to the float valve in the holding tank. The yellow line on the top of the
water shutoff valve is coming from the outlet of the carbon filter. I thought
that when the float valve closed off, it built pressure in the blue line and would shut off the flow throught the yellow line to the membrane. If that is the way it's suppose to work...is the shut off valve sticking. Can I work on
something like that.
