R.O. Unit question

On my R.O. unit, as well as many other units there is a valve for the waste water so you can control how much waste/good water you make.  My question is this, is you flip the switch to let more waste water through does that translate to better good water?  My thought is the more waste water you have the cleaner the good water will be it will just be a slower process of making it.

Didn't know if I was right, but in my head it sounds right haha

 

Sounds right.. I dont have an adjustment vavle but I would think the sol purpose would be so that when you have clean membranes and filters then you could run it almost closed where as as it gets dirty you could start to open it up and still get cleaner water...

 

I didn't really think about having new -vs- old filters, but it makes sense.

 

That valve is to flush the membrain out this allows more good water to be made. I open mine about once a week to flush. When it slows down some open it and flush for about 30 seconds then close. There is a small orfice that keeps the presure up to force water through membrain.If you leave open you are just wasting water and not getting any use of it. You can go to The Filter Guys web sight and see how it is plumbed to make sure yours is hooked up right.

 

Should look like this.

Some units like mine has the orfice in the valve and it dont have the line that bridges the orfice tube.

 

Mine looks like Whitneys

THe long thing between the T's is a orfice that matches the flow rate of your membrain if you change the GPD you have to also change this to get the flow through the RO membrain right. Here is what mine looks like it is all in one

 

Flow restrictors can be purchased for upgrades to the unit.

yes but quality of water goes down unless you upgrade the  membrain to.

 

Re: Re: R.O. Unit question

I have yet to upgrade my membrane to 100gpd.
75gpd-600 restricter
100gpd-800 I think.
