SR-Elite RO/DI 1:1 Ratio Extremely Efficient

[Myka]

BWI, what's the scoop? Any answers for our questions?

[Coleus]

what is the magic? Do you sell retrofit?

Yes the membrane will fit any standard membrane housing!

Btw, clicking on that banner doesn't link properly.

The membrane will last the same amount of time your standard units will or longer because of the auto flush kit.... The auto flush kit will flush the membrane right at start up for 30-40 sec which will also prevent TDS creep, and periodically will flush the membrane when the units running!

Thank you for finally answering some of my questions. So...what brand are these membranes? How are you achieve 1:1? This is an important question because membrane life expectancy could be compromised, and I don't find manufacturer claims to be sufficient. If you could please explain this, I would still be interested in a retrofit.

I use a flush kit on my current system, and I use it on every start up as well as flushing after every use. I doubt that standard home water pressure is good enough to flush the membrane very well, but I do it anyway.

how much for the retrofit and 2 150gpd membrane?

I think there just using a normal membrain and by setting the auto flush unit to flush frequently during production it keeps the build up lower.

If you have enough water pressure to make RO water you have enough to flush

Steve, when the valve is open and it bypasses the flow restrictor for flushing there is only 30 psi through the unit. I have a friend that is a pro ro guy and he told me that isn't enough psi to flush the membrane well enough to make a difference. He said flush kits really only work on high psi commercial systems. Maybe that's not true...I don't know.

I think you're right about the membrane. I flush my membrane a few times mid-use too, and always make sure that my storage barrel is almost empty so I make 50 gallons at a time since the membrane will last longer than frequent, short uses.
