ro/di cutoff

[georgeortiz]

Alright,
Does anyone know of another solution to cut off my ro/di to my makeup water resevoir?
I have put a float swicth in place for sump autotop off which, is working beautifully but, I am periodically having to refill my resevoir because my kent float valve system is not working correctly. It stops flow to the resevoir but, never shuts off the ro/di unit waste water. I have spoken to kent, they have blessed the way I have it setup and even sent me replacement parts. I am just chalking it up to the fact that maybe my ro/di unit is not going to work with this solution. Sooooooooooo, Does anyone know of another device I can use to cut off my production or really my waste water when my resevoir is full. I remember seeing an electonic DIY solution but, I lost the website.

Are you using one of These kits (http://www.premiumaquatics.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=KENT-AUTO&Category_Code=kentroac) with the solenoid valve?

This works great on mine!

I am using the same one.

Hum ... mine will continue to run for a few minutes until the pressure in the 1/4" tubing is enough to trigger the solenoid to close. How's your pressure, does the RO/DI have a pressure valve?

No it doesn't have a pressure valve on it. I think the pressure may be the problem. That is why I would like to see if there are any other alternatives.
