The last couple of days I have been planning out my plumbing for both my tank and my RO filter, And some questions have arisen.
I know how I will be setting it up, But unlike most people, I will be using a booster pump to run the system at a high pressure, about 120 PSI to feed the filter itself.
I got thinking of how the system works, and im a little confused about the ASO valve.
I purchased a 90% ASO valve, But how will it work in conjunction with a booster pump?
My storage tank will be pressurized to 75 PSI (regular tap water pressure), and I will have a pressure switch for the booster pump, that will turn off the pump, at 75 PSI as well. (Tank reaches 75 PSI, booster turns off, and stops feeding water to the RO filter)
Here is my quandry, With the RO's ASO valve, if I understand them correctly, it will cut the water flow to the membrane, once the pressure in the tank reaches x% of the feed water pressure.
that means, at 120 PSI, the ASO valve wouldnt cut the water flow, until the tank reaches 108 PSI (90% of 120 PSI) meaning, that it wouldnt even be working in this highly pressureized system, although the pump would prevent any further water flow when it is turned off.
so this raises a problem, did I waste money buying this 90% valve when it wont even be needed? If i use the default 65% ASO valve that came with the filter, then it will cut the water off when the tank reaches 78 PSI, so I could also use the original ASO valve.
And all of this is, of course, assuming that I correctly understand how these ASO valves work.
So, with the booster pump having its own pressure switch to shut it off when the tank reaches 75 PSI, and the pump stopping water flow when its off, is an ASO valve even needed? especially when its rated to shut off the water flow at a pressure higher than the tank will be pressurized, due to the high pressure water feed.
even the original ASO valve wont cut off the water to the membrane until the tank is at 78 PSI.
Also, im not 100% sure, but I think the Aquatec 8800 series pumps are open flow, meaning that when the pump is off, water can still flow through it.
with no ASO valve, water will simply be pouring out of the waste water line and right down the drain.
Im not sure if i've been too clear on the problems, but im hoping someone can offer some advice/knowledge/experience.
Thanks.
