I have been reading a bit about how to best use an RO/DI shut off on big tanks like yours. Since being in a bigger house now, I now have the room for a couple of bigger tanks.

Float valves turn me off for some reason, I think I like a bit more of a challange, plus I have heard bad things about their sticking and flooding. I am looking into 110 volt valves controlled by an on off timer, so the RO/DI unit will crank out 5 gallons a day. My unit produces 1 gallon every 14 min. with the water pressure here. So, I'll let the valve run for an hour a day. That should give me about 4 1/2 gallons a day, which will be a good supply for when I do water changes twice a week of 5 gallons.

When I get the 90 up and running again, I'll just increase the time on the timer.

The valves I was looking at are plastic shut-off valves that are used for supplying water to the ice maker in a fridge. These have been pretty easy to find at my local appliance store, but they were a bit costly. When I find one with a better price, I will be picking up a couple.
