Just trying to get some advice.  Planning on doing some maintenance on my 
unit, which has never been backflushed in the three years I've had it.  and 
since this unit doesn't have a backflush kit available, I was wondering if 
it is possible to  pull the membrane out of its housing and clean it, say 
with acetic acid, and/or peroxide.  Any suggestions?

You can pull out the membrane, using pliers.  The housing can be washed 
with vinegar and water.  The membrane can be soaked in vinegar water but 
I only recommend that if you are in a real pickle.  The membrane is 
typically good for 3 to 5 years, so you *might* consider inserting a new 
one in the housing once it is all clean, while you have it pulled apart.

Thanks  for the info.  I will likely try the vinegar solution first, since 
I have to buy the other filters, and don't have the bucks to shell out for 
a new membrane right now.  If the vinegar doesn't work as expected, I'll 
have to consider buying a new membrane.  Again, thanks.

Is the vineger wash valid for all types of membranes?  CTA, TFC, PA 
(polyamide), etc

Not being sure what type of membrane I have, I simply rinsed it as best I 
could and put it back in the housing after I sterilized the rest of the 
unit.

Yea that's a good point you brought up, especialy since 
the "a" in cta stands for acetate ie vinigar. Meaning it 
was made with acetic acid, so I might well be dammaged by 
acetic acid.
