Hi fellas as above have had a new pure freedom RO and DI for around 2 months now, until now has nearly always been producing at 000pm and fairly quickly. probably 25 litres an hour. Just yesterday started producing at 003ppm and at half the speed. I have flushed the system today and yesterday and this has not helped.
I've only been producing around 75 litres a day and only a few days a week as just starting out wfp. For this reason I can't see the problem being the resin running out. So in 2 months I've probably only produced around 2000 litres. I have flushed the system regularly (every few days for around 5 mins) and also flushed whenever it hasnt been used for more than a day. So should all be in good condition.
Any ideas what is could be? Or anyone has similar problems?

cold weather slows the production down .
what gpd is it .
-
Thing is the last few days have been the warmest since I bought it! Its 450 gpd. Water before RO is around 320ppm same as it has been since purchase.
For example of the speed now its been running for an hour and 40 mins and produced around 11 litres. Still at 003ppm. It is not set to flush.

I keep a semi regular log of tds readings after RO and after DI, this can come in handy if you have tds problems
What size resin vessel are you using
What is the tds reading after RO as this might explain why your reading has gone up
Resin doesn't last forever
Even when I'm not using much water I try to empty the holding tank so I can leave the water running for longer, don't know why but my resin seems to perform better when it gets a longer run rather than short bursts
As for the speed I would check for blockages (unlikely, but won't hurt ) or it might be something simple like water pressure problems in your area

Also make sure you disconnect your resin when flushing
-
when you flush disconnect the resin filter , otherwise this will deplete the resin
i have the 200gpd unit which produces 1000 ltrs in 2 days at 120 psi and 230 tds normally
does slow down with the cold weather tho
-
Thank you Scott and Mike, unreal I never even thought of disconnecting the DI when flushing :o
learn something new everyday! Cheers fellas.

I had mine slow to a trickle a couple of times - the paper and chlorine filters had started to clog. The second time I had to replace the membranes after about 18 months.
Flush regularly, change filters regularly.
I have an input pressure gauge which sits rock steady at 82psi normally - it had dropped to about 60psi because of the clogged pre-filters when the speed slowed.

Its the temperature of the water that counts, not the day temperature. The water coming out of our tap is freezing cold.
