Float Valve for BRS RO/DI Units

Breakthecycle2 · Jul 17, 2015

Just a quick question: How the heck do you install this thing? Three times I made an error and forgot to shut the water off and you can guess what happened next.

Works the same as a toilet. Water level drops, float drops, valve opens, water level rises, float rises, valve closes, shuts water off.

But I meant, how do you install it?

this type?

YEs sir.

Mine I installed through the side of a Brute at the point I wanted to consider "full" with the float hanging down and the valve open. I have a 1/4" ice maker line from the rodi to the valve. Barrel fills and valve shuts off. The rodi has an auto shutoff. I do not let it continuously top off the barrel as I use rodi water.

is it connected to a RODI unit, or ATO?

Sorry...is what connected? I have the RO/DI unit hooked up to my sink in my laundry room. I turn it on and off when I want to make some water.

No worries... is the reason that you are using a float to cut off filling a water barrel of topping off a sump/DT?

Exactly. Yes.

drill a hole small enough for the float end to pass through, install the washer on the inside and the plastic nut on the outside, than just plum the outlet (norm Blue line) off the RO/DI to the inlet of the float.

The inlet has to nuts, one to secure it to it mounting point, the other to secure the blue line to the float with a compression fitting.

Make sure the orientation of the float looks like it does in the picture below... as it fills it will cause back pressure to build and the RO/DI unit will stop emptying into the ATO container.

That help?

Yes it does, only question I have is, if the water is manually turned on, how will it shut off?

143MPCo · Jul 17, 2015

most RO/DI come with a auto shut off valve... like the one below, 1/4" Automatic shut off valves are used with float valves or pressurized tanks to shut off an Reverse Osmosis system. It utilizes the back pressure created by the float valve or pressurized tank to shut off the water supply to the membrane. Without an automatic shut off valve waste water would continue to run out after the float valve is activated or tank becomes full.
