Coralife Float and Automatic Shutoff Valve Kit
I got tired of overflowing buckets and bought the Coralife Float and Automatic Shutoff Valve Kit ( http://www.esuweb.com/cardfile.asp?I...lationship=293 ).
Does anyone else use this? I still haven't filled my holding tank, but I lifted the valve and held it to test the shutoff. It shuts off the water to the holding tank but lets the water continue to flow out of the waste line on my RO/DI. Is this what it is suppose to do? I was under the impression that it shut off the water completely.
What exactly happens is when the valve is raised, the water stops to the holding tank. The pressure on my RO/DI initially climbs and then drops down to the previous pressure. Water continues to run out of the waste line the entire time. I held the valve up for about a minute, does it take longer than that to shut off?

i do not have one, but was thinking of using one for something else. 
the shut off valve has both the outlet and the inlet from the RO/DI going through it. when the float valve is raised it increases the pressure in the shutoff valve. this increase in pressure causes the valve to shut off the inlet side of the RO/DI feed.
does this make sense?

I followed the directions sent with it but it doesn't shut off the water feed. Seems to me the shut off should stop the main feed to the RO/DI so water would not continue to come out of the waste line. The directions have the valve turning off the feed between the micron and the DI.

the ones i have seen installed go before the RO/DI unit.
Fly- they are usually around $15.

I just looked at the shutoff valve on mine and the water goes through the prefilter then to the valve, out of the valve into the ro membrane housing then out of the ro housing into the valve then out of the valve into the di housing. If you've followed the instructions in the kit the only thing I can think of is to make sure you have the valve installed right side up, they have a top and a bottom but I can't say whether it make a difference or not though.

Tried all of the above to no avail. Think maybe I have a bad valve. The RO/DI unit I have is a Spectra Pure. I went to their site and looked at the Auto shut off they offer and downloaded the directions to see if theirs was somehow different. It was identical as far as hook up. I have it testing now one last time before I call to get a new valve. I got it from Drs Foster and Smith. They seem to be good about replacing defective items.

Found that my valve was stuck. A quick tap and it started working normally.
Thanks everyone for the help.

I've installed a number of them, they take a while for the back presure to build enough to shut off the flow. Of course how long depends on your input water presure, I've seen as much as 1 minute delay when the house presure is very low.
Also be careful of the hinge pin, they are kind of cheaply installed, I've seen them come in off center and the float could never "make".
Best of luck with it
