Is there any problem with over flushing membranes?
I tend to flush them quite a lot, sometimes leaving it overnight.
Is there any negative effects to flushing membranes a lot or is it only positive?
-
why would you want to flush over knight. if in doubt ask the maufacturer.i flush mine for 20 mins once a week and have done for the last 4years
-
overnight :o
take it you are not on a water meter then ? :D ;D
-
Accidently left mine flushing with the booster pump running for ages, no damage luckily.
-
The only downside to overflushing your membranes is shortening the life of your pre filters.
-
Very rarely flush mine, if that's all the flushing does is save the life of the membranes don't think ill bother !!!! I changed my last membranes last year had about 5 years only cost £90 for the three of them !!! 450 GPD RO !!!😝😏😝
-
My last one lasted about five years too,I put a new one in about three weeks ago

With my little 450gpd ro when I flush the membranes it produces pure at 000. Wheras when I'm not flushing it it produces 003. It still produces about 700 litres of pure a day while it's in flush, which is fine for me, So was just curious if I could keep doing that.
Thanks for input guys.

Jonny if your producing 000 water then your not flushing.
What your actually doing is running a higher percentage of water to waste.

Really? I thought it was normal.
When I open the flush valve the water rushes out the waste pipe very quick, but I still get a lower flow rate of pure. Reads 000.
I thought when ever you flush your membranes you still get a little bit of pure production?

Agreed, and prefilters are cheap as chips.

I think it is normal for certain types of R.O. but what I was trying to explain badly is that all waste water is flush water.
So if your running at 20% pure to 80% waste then its not a full flush but the extra flow of waste water should still clean
the membrane.
I cant see any problem with the way you are running your R.O. other than using extra water.
