Is this RODI setup correct?

[-=James=-]

Help! After setting up my AquaSafe 7 stage 100GPD RODI unit, I turned on the water just to find that it shoots right back out of the reject tube (Yellow) with lots of pressure.
Not a single drop goes out the RODI tube. The cartridges are used but still have good life left.

Is this set up correctly? Any thoughts?

Heres a pic: Red is water in, Yellow is waste water, Blue is RODI water

Your variable flow restrictor which is on the front of the unit with black handle ( I believe) needs to be adjusted. Adjust it until you get a 4 (waste) to 1 (ro) ratio. Its either 4 to 1 or 3 to 1. I cant remember. You probably have the flow restrictor open all the way so right now you are essentially flushing the membrane.

How would he "flush" his membrane?

Piped wrong, look at sphelps's picture.

You are coming out of the prefilters and through the flow restrict and into the membrane with no restrict or on the waist line.

By opening the valve on the flow restrictor, the item with the black lever. In his photo, the lever is shown in the 'flush' position. To make water, the lever goes 1/4 turn, much like any conventional ball valve. Having the valve open reduces backpressure in the membrane housing so all the water bypasses along the outside of the membrane, flushing it. Once the handle is turned 90 degrees, the built in restrictor creates the required amount of backpressure in the waste line to cause some of the water to get pushed through the membrane and purifying it.
