RO/DI Unit Stopped Working

[jayjeep]

I just got a RO unit for the tank that I will be setting up shortly. I set it up about a month ago and just made about 10 gallons for my QT tank. I went to make more water and nothing comes out. I can adjust the EZ flow restrictor but nothing ever comes out. I get water pressure to the auto shut-off valve and waste water comes out but ro water does not come out of the membrane.
Any ideas? I suspect the Auto shut-off valve or something wrong with the ro membrane.
This is what I got.

Sometimes the water is too cold this time of year to go through an RO filter properly. Take the temp of it as it goes into the filter. If it's below 60F then it should be warmed up before going into the filter.

Agree......

One more thought. Some RO membranes have a large gasket near the output end of the RO filter. If that gasket is folded or out of round then the good water can leak past and go into the waste water stream. If this happens some of the waste water will also leak back into the good product water. The symptom of this is very low pressure on the good water output and a higher than expected TDS.

How do you warm it up?
I also took the membrane out and ran it. It flowed fine so I know the check valve is fine. I'll have to see what the temp is on the water, I didn't know that would affect it.

OH YEAH...this happened to me once....BUT it was the gasket on one of the other filters....I would check all your filters

To heat the water or warm it, you could extend your feed line to the unit and could the line in a bucket with water an a heater to warm the input water before it enters the unit.
