RO update part 2
 

Ok the weekend finally came and I had some time to re test the RO unit.
I let the thing run for about half hour before testing.

The test consisted of two 5 gallon buckets. One RO water one waste water.
I put the tap on full, and let it go for ten minutes. In that time I filled the waste bucket with 4 gallons of water while the RO bucket I got a cup.
These means that the RO unit is producing 1/2 of what it is supose to and wasting a ton.


The temp of the water was 10 degrees C or 50 degrees F

Did any of you see a increase in your water bill after using your RO unit.

I have a booster pump if you need it!

I dont know if its the pressure that is causing the slow down. We usually have good pressure at our house.

I had a 24 GPD membrane and all I would get out of it was a drip, simmilar to what you have been describing. My house preasure is 40psi. What exactly is yours? You can by a tester at Canadian Tire fairly cheep, under $20. But adding the booster pump gave me the proper ratio of good to bad water, by boosting the preasure to about 95psi. But you need to know what your house preasure is.

I ll have to check with my Dad.
He would probablie know if he dosnt ill find out.

After you added the pump did you the drip turn into a good pour.

Josh

Yes you would get the 24gpd out of your unit.

sounds like you either 1, don't have enuf pressure to make the membrain work.. or 2, they forgot to put the backpressure restrictor in the discharge line.


Steve

is there some way of checking whether they put the backpressure restrictor in the discharge line.

Josh

Take your discharge line off your RO housing and inside there should be a restrictor piece with a small hole in the center.

Yeah it looks like there is a restrictor. I took off the waste water line and looked down the hole and it gets slighting smaller and then I would assume that it gets bigger again on the other side.
I guess that rules that problem out I still have to check on the water pressure.

Thanks
Josh
