R/O acidic water back-flush.

[Leroy Mowry]

I am back-flushing the reverse osmosis membrane with an acidic
water generator, (actually a pH 3.0 water ionizer.) I am hoping to
kill bacteria and flush out deposits. The pressure from the ionizer is
probably 35-45psi. The ionizer is generally used to wash fish,
chickens, cutting boards, fruits and vegetables. I am worried that the
acidic water will eat off and destroy the R/O membrane. What is
the likely chance that I may do serious damage?

Thanks
