Thanks Brad, I'll try it

I 'backflush' my unit weekly for a few minutes (or hours if I forget :doh:) before I run it, but I too am curious to see what comes out
Judging by what my pre-filter catches I expect to see some crud

For the record, I was lead to believe the 'film' in my mixing tank was from some kind of clay in the salt mix that's used as a 'stabilizing agent' of sorts. I don't know ... haven't really delved into it as it's never hurt anything

OK, the super-secret flush is done :smile:

Nothing but clear water came out of my RO system, so it's lookin' good
Albeit, my membrane is only 10 months old, and my incoming TDS is usually between 12 and 6-7, with tonight being a whopping 5

For now, I'm gonna blame the sediment in my NSW tank on clay in the salt mix
But, it sure would have been nice to find muck coming out of my system so I could eliminate the need to clean out my NSW tank every week :biggrin:

The sludge pre and post flushing for me was quite different.

If you got nothing, maybe you did it wrong. My membrane is only 6 months old, and I back flush every other week. I got mud out of mine!

I might make a lot more water than you though, so who knows

I pulled the pre and carbon filters and put the canisters back in place
I also pulled the blackwater hose from the drain and put it in a bucket
I opened the water valve and then the flush valve. Lots of air came out and clean water followed. After a couple litres I closed the flush valve and clean water came out the RO end for another couple litres

Did I miss something ?

My membrane is 10 months old vs your's at 6 months
Maybe my input water is cleaner than your's ?

Oh, and I only make about 50g/week - which translates to over 1000g/month with washing hardware and such. Good thing I don't currently pay for water on a meter :surprise:

I dunno, that sounds right.

Sounds like bedtime to me
