Stop Floods and Wasting Water with the Only Electronic Auto Shut Off Valve Kit for RO/DI Systems

XP Aqua RO/DI Flood Guardian is the perfect solution for any reefer that wants a float valve that they do not need to drill or permanently mount to a reservoir. The Flood Guardian uses a dual optical sensor that can be magnetically attached to 5-gallon buckets, ATO containers, or even large saltwater mixing reservoirs, but then moved to any other container within seconds without leaving any holes behind. When water reaches the optical eye, it will send an electronic signal to the controller which will shut the included solenoid off, stopping the flow of water. 

  • Automatically Shuts Off Your RO/DI System
  • Installs and Uninstalls in Seconds
  • No Holes or Drilling
  • Magnetic Mount
  • Dual Optical Eye for Safety
  • Works in Complete Darkness
  • Includes RO Solenoid Valve
  • Eliminates Waste Water Run-Off


Optical Sensor Installation

The optical sensor can be mounted in any reservoir with a wall thickness under 1/2" at the level you wish to fill it up to. The cable should be positioned vertically which will stack the optical eyes, allowing it to utilize the dual sensors. The sensor can be placed in a bright room or even in complete darkness. 


Solenoid Valve Installation

RO/DI System without an Auto Shut Off Valve - The solenoid valve should be placed between your RO/DI systems pre-filters and the membrane. It is important to place the solenoid after sediment filters, or even better after carbon blocks to remove any particulates that could clog the solenoid valve. Installing the valve before your RO/DI system can cause the solenoid valve to fail prematurely. 

RO/DI System with an Auto Shut Off Valve - The solenoid valve can be placed anywhere after your DI and before the water enters your reservoir. This method will let you use your RODI system like normal if you split the RO or DI water off to any other reservoirs while allowing the XP RO/DI Flood Guardian to work properly on its own.

Product Questions

Does the sensor need a clear water reservoir?
Question by: Don on Jan 24, 2023, 1:28 PM
Hey There, this does not at the sensor is reading from inside the reservoir!
Answer by: James Johnson (BRS Staff) on Feb 9, 2023, 10:44 PM
Does this go between the water supply input to the RODI unit so that it stops the water going into the RODI from water supply line?
Question by: Don on Feb 28, 2022, 12:19 PM
The Flood Guardian goes between the Carbon filter and the membrane.
Answer by: Scott F. (BRS Staff) on Mar 4, 2022, 4:38 PM
Can this be used with the 4 stage BRS RODI?
Question by: Christopher Brizzee on Feb 2, 2020, 3:47 AM
Yes it can be, make sure to follow the install guide that it will come with to make sure it is in the correct position!

Take care

My water pressure is below 40psi so I cant use a standard float switch without a booster pump. Will this work with lower pressure RODI systems? My system operates around 30 psi.
Question by: Brian on Oct 22, 2019, 8:29 AM
Hey there!

It does not have a minimum PSI to operate, it is simply a soleniod that opens and closes. So it will be fine to use with low PSI.

What is the length of the optical sensor cable?
Question by: Jose on Aug 21, 2019, 4:15 PM
Hey there,
Thank you for reaching out to us. The optical sensor cable is 10' long.

Please let us know if you need anything further and take care!

What happens if you lose power? Will it shut off or keep flowing water?
Question by: Sandra Thompson on Aug 6, 2019, 7:40 AM
Hey there!

In the event of an outage the solenoid will stay in the position it was in before the outage. So, if it was open and the power cuts off it will stay opened.

Take care!
