RO update part 2

The hole should be around the size of a pin hole and removeable. The restrictor should be about 1/2" long if memory serves me.

[StirCrazy]

it should be a cartrage.. if you can pull it out it should have writen on it what size it is for.. you want to make sure it's rating matches your membrain.. but failing that.. do you have a way to check your water pressure ? if so what is it? if it is two low or at the min operation PSI you will not be able to penatrate the membrain properly and you will get barly any produce out of your unit...

I just run my waste water down the laundry line. They recycle that down at the sewage plant I guess...... I've tried using it for a few things, but in winter I can't do much with it. I know my output is really a lot lower because of the colder water in winter (makes darn pure water tho...). I only get 42 psi out of the tap.


I teed into the hot and cold last year, it made a big difference for me on the output. But it was too hard to control the temp, and I feel it subsequently lead to an early departure for my membrane...........

When I'm just looking at hours vs output, I'm okay with what I am seeing. I'll measure the waste water tonite and see what kind of volume I get. Then I probably won't be so okay........

Actually, quite a nice surprise. :shock:

Not even 4:1 actually about 3.25:1



I will add that we just replaced all the cartridges and the membrane last week.

Would the micron size of the cartridges affect this as well?

when I took a look in the waste water line I noticed that there was a restrictor although there was no way to remove it. The tub just got smaller about a inch in and then I would asume it got larger on the othe side. There is no way to remove it. The hole itselft is about the size of a pin. Still working on the PSI.
