Float valves are simple to install and can save a lot of water from ending up on the floor. They can be installed in containers as small 1 gallon pails, sumps, and 200 plus gallon commercial storage containers to shut off the flow of water. Even if you do not have a large storage container a simple 5 gallon bucket with a float valve installed in it will help save money from having water end up on the floor or best case scenario just going down the drain.
Float valves are used to shut down your reverse osmosis system when the float is elevated. Float valves are typically installed on containers like large plastic food grade trash cans or other containers. Installation is as easy as drilling a small hole in the container, sliding the float in and attaching using the included nut.
1/4" tubing inlet and free flow outlet
Suitable for containers with up to 1/4" wall thickness
Estimated flow rate of 1.5 GPM at 40 PSI
Tested to 100 PSI
Approximate diameter is 1.4"
Flange to float tip measurement is 5.7" - Inlet adds approximately 1" to overall length
Comes complete with jam nut, sealing washer, JACO compression nut and polyethylene float
Hardware made with 18-8 stainless steel
Bodies made of NSF approved PVC
Replaceable seals are made of long-wearing, chemical resistant Santoprene rubber.
Note: Requires 1/2" mounting hole. Maximum container wall thickness of 1/4". To shut off your waste water you will need an auto shut off valve and check valve. If you don’t have these please purchase the “Auto Shut Off Kit.”
Can the blue line be disconnected from the container after the container is full? I move my container from the water source to the aquarium and then store the container in a closet. My WC method will not work if the blue line cannot be connected/disconnected each time I make a new batch of water.

You can disconnect it from the valve. It will still have part of the volute on it which is fine.

Is this okay for use in saltwater? The little metal pin is what concerns me
Question by: Ryan Oconnell on Jan 19, 2018, 4:26 PM
Yes, they can be used with saltwater. The pins may slowly show a little surface rust over time, but no harm will come from it. Depending on the area that you mount the float valve in, you should get a couple years out of the float before rust is a concern.

Hello, I purchased the 6 Stage 75 GPD Plus RO/DI System from Bulk Reef Supply, and I'm considering purchasing the PSI Booster Kit as well. 2 questions I have are 1. Is this all I need to purchase to stop the flow, or do I need the whole float kit? 2. Is this compatible with the PSI Booster? Thanks!
Question by: Dace on Nov 14, 2017, 3:07 PM
Thanks for asking, and all you would need to increase your pressure is the Booster Pump Kit. Your RODI system already has an Auto Shut Off Valve installed along with a check valve. After the booster pump and pressure switch are connected and energized the booster pump will turn on when there is no back pressure in the product water line. By using a float valve or ball valve on your product water line to shut off the flow will slowly create back pressure in the line and once it reaches about 40 PSI the pressure switch that comes with the booster pump will activate and the entire system will shut down, even the waste water.

Does this create a water tight seal? If I ever want to fill the container higher than the level of the float valve later on, is it likely to leak around the valve hole?
Question by: Dan on Jun 8, 2017, 7:48 PM
These float valves will provide a water-tight seal once the container is filled to the set level of the float.
Have a great day!

I want to install this valve so that the water level in my storage container is at a specific height. Where will the final water level be in relation to the 1/2" hole needed to install this float valve?
Question by: Rick on Dec 31, 2016, 11:00 PM
Great question! The water level will be even with the bottom of the drilled hole. :-)

Do you carry the diamond coated drill bit for this float valve? And, if so, then what size would it be? Thanks!
Question by: Fred on Jul 19, 2016, 12:18 PM
We do not carry a drill bit for the float valves. You will need to pick up a ½” drill bit, which you can usually find at your local hardware store for pretty cheap.
Thanks for the question and if you have any more, just let us know.
