RO System Question for everyone

[AHAB]

Hey Ray,
I used a float valve like the one below in a fifty gallon barrel it shuts off the RO when it has gotten to the level you preset.
This really helps since you can turn it on and walk away without the worry of an overflow.
This might be good for the other option.
Thanks again for all you do!

Ahab - I do exactly the same.

Goodgolly - The home page is probably one of the simplest on the site. I do have a hidden link for tracking statistics, that I just removed, so give it a try.

Still crashes, Ray. It gives me the "IE 7 has encountered a problem and needs to close" warning. 'Course it wants to tell Microsoft about it...why I don't know. Bill Gates wants to folow me to the restroom I guess.

Both my computers are running IE7, both use Norton IS but this one that crashes has been updated from Norton IS 2007 to the same 2008. The problem started at the same time as the uppgrade, however the entire harddrive was also returned to its "ship state" and repopulated with additional sofeware at the same time so a lot more than just an upgrade occurred.

I'll figure it out eventually and let you know.

Back to float valves. In my cooling cell tank I use a regular toilet float valve from Lowes and it works great. This use is a little more difficult than just preventing a tank overflow. The level has to be controlled at the level attained when the cooler is operating so it's about at 1/2 tank in my case. So this toilet valve is located about 1/2 way down in the tank. It has to supported securely because it wants to float obviously when the cooler quits and the tank fills to the top. It's done a great job and only cost $6.

I'm a little confused about what ya'll are doing with float valves you are using. No problem understanding that it shuts off purified water to the tank. But...does your valve have an electrical output so that you can turn off water supply to the RO unit? If not, what happens if you allow the RO unit to operate? Does it send all water to drain until you turn it off manually? All the vaves I saw on the page suggested seem to be mechanical (like a toilet valve) so I'm puzzled at how ya'll are doing this.

1) Try it now. I have had no crashes with IE7 or FireFox (my personal preference), but did find some code from an old version, that might have been tripping up Norton.

2) Most RO systems I have seen have a pressure shutoff valve. Once the toilet-valve shuts off outlet flow when my tank is full (or when the bladder tank is filled, if you use one), that back-pressure causes the shutoff valve to stop the flow to the membrane. If it wasn't present, all of the inflow would be redirected to the wastewater line and keep flowing.

OK, I understand how the mechanical shutoff works.

I tried the homepage again. Same result..crashed. I turned Norton IS completely off and tried again...crashed. The problem has to be in my IE7. I will dump it and reload it to see if it improves. I have reduced all security settings on IE7 to the minimum setting without success. Obviously this problem is on my end. I'll figure it out.

Thanks
