Had old membrane in place for about 1 year. Had purchased that membrane (blue colored housing) from different company.
Replaced it with this new membrane (white colored housing) after flushing the new membrane with water under as high pressure as possible from our house faucets.
Could not seem to get ANY water through new membrane so removed and flushed with water multiple times before replacing it in chamber. Still getting very limited water flow through this membrane. Seems to be due to protective material used to protect it and perhaps still not completely flushed.
Don't know how homeowner is supposed to clean this membrane out to get full function.
