RO Alert!

[bang guy]

It's that time of year again. If you're new to Reverse Osmosis filters be wary of what happens when your tap water gets colder.
As the source water for your RO gets cold because of cooling outdoor temperatures it becomes a lot more viscous. This means it's a lot more difficult to push the pure water through your RO membrane.
The result? If you don't warm the water before it goes into your filter you'll notice a drop in productivity. If you have an auto-shutoff, it may never get enough pressure to shut off and will run constantly. This could waste thousands of gallons of water.
Just be sure to check your RO to make sure it's working properly when it gets cold outside.

Great post, Bang. I do not think many people know this about RO units.

It's in the instruction manual, if they read them...

"instruction manual" ..... What is that used for???
Any quick fixes for this problem? Would looping extra tubing inside the cabinet allow the water to warm up enough to help?

My ato is hooked up to a timer and will only run 20 min every 4 hours before it shuts down to prevent just this kind of disaster .Solenoid + float switch=

Just installed my new 5 stage 75gpd bulk reef supply unit yesterday. I have the supply line coiled in a bucket of 80+ degree water. Baby is cranking out about 4 gallons per hour (96gpd). Output water is 72 degrees. Tap water has about 90 TDS, RO water is showing 1-2, DI showing zero. All is good
