Title: RO Operating Pressure
Post by: Oakley Windows on January 15, 2009, 04:48:25 pm

What would you guys say is the maximum operating pressure for a 300 gpd RO Man system? Is over 100psi okay or would you say thats the max?

Also does flushing at higher pressure give a more thorough flush?

I have run one at tap pressure of 140psi and it worked great.  Waste to product ratio around 50/50, and produced around 450gpd.

Well, that sounds great, but what sort of pressure can membranes tolerate?

Just got a booster pump recently and it can be tweaked up, how high is safe without doing the membranes in?

You`ll always have enough and it will make water quicker unlike the fish tank 1 you have.

I can't remember your ever telling me nwh, but if you did i wish i'd listened. I got one because of breakage, but now i have one, would glady bin  what you call the fish tank thing.

No more leaving it on overnight, or when i'm out working all day, and if i did there are only two hoselock connections and no electrics at all.

I remember dave morriss posting about water production, what route did he go?
