Float Valve Problems

[kfowler]

I currently have my RO hooked right into my sump with a kent float valve.

Can someone tell me exactly how the Kent shutoff kit that Kristy mentioned above works?

I also noticed that here

"The Float Valve Kit allows an RO to fill a reservoir to a desired level, then shut down water production completely.

This kit works from pressure only, no electricity.

Included within this kit is a pressure solenoid, float valve, check valve, a 1/8" elbow, a male 1/8" x 1/8" connector and 1 foot each of blue and orange tubing.

Not recommended for level control in aquariums."

Right. Basically when the container fills, the float valve closes off the line. The backpressure then triggers the solenoid and shuts off the water to the RO unit. They don't recommend that you use it directly to your aquarium because if something fails your aquarium fills with RO water and can kill everything with a massive drop in salinity.

But I could hook this shutoff kit into my sump so if my float fails at least my house won't flood?

The shutoff kit is designed to be attached to where water enters your RO unit (my understanding of it at least). That way you aren't running water down the drain by just shutting off water coming from the RO unit.
