That's hard to say, I never really watch it enough to make an accurate estimate, but off hand I would say more like 8-10g a day?

So, if in-line with the RO/DI you suggest a solenoid to shut off the water flow, and connect the solenoid power to the top off controller ... hum, that might work?

Any suggestions for a source/model for this solenoid?

Can you please PM me with the price for a three footer? Of course I would get a "Beta Tester" discount, right
