Description
The FR-FLUSH anti-flood valve with pressure gauge is a practical set of accessories for RO installations that supports the safe and efficient operation of devices such as reverse osmosis, osmotic filter or a complete reverse osmosis system. The set includes: a pressure gauge for 1/4" tubing, an Aqua-Stop anti-flood valve, and FR-FLUSH with BY-PASS for periodic membrane flushing. The set helps control the operation of the installation, reduces the risk of flooding, and supports longer, more stable operation of components such as the osmotic membrane.

Complete accessory set for the RO system
This set was designed for users who want not only to filter water, but also to better control the operation of the entire installation. It is a functional addition to a water filtration system based on reverse osmosis, combining three important areas: safety, operating diagnostics, and proper membrane maintenance.
With this solution, a water filter operating in RO technology can be easier to monitor and maintain, and regular parameter checks help identify drops in performance or system irregularities faster.
What is included in the set
- Pressure gauge – allows water pressure measurement in reverse osmosis (RO) filters on 1/4" (6.4 mm) tubing. It can be permanently installed or used for individual measurements.
- Aqua-Stop anti-flood valve – protects against flooding by automatically cutting off the water supply to the filter in the event of a failure.
- FR-FLUSH – a set for flushing the RO osmotic membrane, equipped with BY-PASS. It allows deposits to be flushed out of the membrane, helping to extend its service life.
Main benefits for the user
- Flood protection – increases system safety and helps reduce the effects of emergency situations.
- Pressure control – makes it easier to monitor pressure in the installation, which may indicate the need to replace cartridges or check system operation.
- Membrane flushing – regular flushing helps remove deposits from the osmotic membrane, supporting its performance and longer service life.
- Better performance – the set helps maintain the optimal operating conditions that a reverse osmosis filter should provide.
How the set works in everyday use
Pressure gauge for monitoring system operation
Pressure measurement is one of the basic ways to assess whether the reverse osmosis system is operating under proper conditions. The pressure gauge connected to 1/4" (6.4 mm) tubing allows you to check the operating parameters of the installation both during a one-time inspection and in a permanently installed configuration.
Regular pressure monitoring can make it easier to spot situations where the system requires service, cartridge replacement, or flow inspection.
Aqua-Stop anti-flood valve
The anti-flood valve serves a protective function. In the event of a failure, it automatically cuts off the water supply to the filter, helping protect the area around the installation from the effects of leakage. This is especially important in places where the RO system operates continuously and remains connected to the water supply network.
FR-FLUSH with BY-PASS for membrane flushing
FR-FLUSH is used for periodic flushing of the osmotic membrane. This procedure helps wash out deposits accumulating on the membrane, supporting proper operation and possibly extending its service life. It is a practical solution for users who want to maintain the efficiency of the water treatment process without complicated servicing tasks.
How to use FR-FLUSH
- Frequency – flush the membrane 1-2 times a month while the system is operating.
- Procedure – open the BYPASS valve so that water can flow freely through the membrane and out to the drain.
- Duration – close the BYPASS valve after about 2 minutes of flushing.
Regular flushing of the osmotic membrane helps maintain good RO system efficiency. In addition, pressure control makes it easier to assess the condition of the installation and may help you notice the need to replace filter cartridges sooner.
Application of the set
The set is suitable as a complement to installations in which reverse osmosis or another water filter based on an RO membrane operates. It is a solution for users who want to combine operating safety with better control of operating parameters and simpler membrane maintenance.
The accessories can be helpful both in the day-to-day operation of a home water filtration system and in periodic diagnostics and maintenance of the installation.
Additional important information
- Flood Protection: Ensures system safety, preventing emergency situations.

FAQ
What is the FR-FLUSH anti-flood valve with pressure gauge set used for?
The set is used to improve the safety and operation control of the reverse osmosis system. It allows pressure measurement, protects the installation against flooding, and enables periodic flushing of the osmotic membrane.
What is included in the set?
The set includes three elements: a pressure gauge for 1/4" tubing, an Aqua-Stop anti-flood valve, and FR-FLUSH with BY-PASS for flushing the RO membrane.
Can the pressure gauge be permanently installed?
Yes. The pressure gauge can be permanently installed in the system or used for individual control measurements, depending on the user's needs.
Which tubing does the pressure gauge fit?
The pressure gauge is designed for 1/4" tubing, i.e. 6.4 mm, commonly used in RO systems.
How does the Aqua-Stop anti-flood valve work?
The anti-flood valve protects against flooding by automatically cutting off the water supply to the filter in the event of a failure. This increases the safety of using the installation.
How often should the membrane be flushed using FR-FLUSH?
The membrane should be flushed 1-2 times a month while the system is operating. Regular flushing helps remove deposits and supports maintaining good membrane performance.
How do you properly flush the membrane?
Open the BYPASS valve so that water can flow freely through the membrane and drain away to the sewer. After about 2 minutes, close the BYPASS valve.
Why is pressure control important in the ANTI-FLOOD VALVE PRESSURE GAUGE FR-FLUSH RO?
Pressure control makes it easier to monitor system operation and may indicate the need to replace cartridges or check the condition of the system. It is a simple method of ongoing assessment of reverse osmosis filter operation.
Does the set help extend the service life of the osmotic membrane?
Yes. FR-FLUSH allows deposits to be flushed out of the membrane, which helps maintain its performance and contributes to extending the service life of the osmotic membrane.
