Description
ANTI-FLOOD VALVE PRESSURE GAUGE FR-FLUSH REDOX is a practical set of accessories for an reverse osmosis system with a REDOX ionizer, supporting safe and stable operation of the installation. The set combines protective, control, and service functions: the Aqua-Stop valve protects against flooding, the pressure gauge makes it easier to monitor the operation of the osmosis filter, FR-FLUSH with BY-PASS helps flush the osmosis membrane, and the air-release valve reduces the risk of excessive pressure after longer periods of non-use. This is a solution for people who want to take better care of water treatment, filter performance, and the safety of the entire water filtration system.

Complete accessory set for reverse osmosis and REDOX ionizer
The set has been designed for users who operate a reverse osmosis filter with a REDOX cartridge and want to conveniently monitor the condition of the installation, reduce the risk of failure, and improve the operating conditions of the RO membrane. The individual elements complement one another and support the daily operation of the system.
This is practical equipment for installations where user safety, the ability to quickly check pressure, and regular flushing of the osmosis membrane to maintain good efficiency are important.
Set contents
- Pressure gauge – enables water pressure measurement in RO filters on a 1/4" (6.4 mm) tube. It can be permanently installed or used to take a single measurement.
- Air-release valve for REDOX cartridge – intended for installation before or after the REDOX cartridge. It prevents the build-up of excessive hydrogen and excessive pressure during longer breaks in filter use.
- Aqua-Stop anti-flood valve – protects against flooding and cuts off the water supply to the filter in the event of a failure.
- FR-FLUSH – RO membrane flushing set, includes BY-PASS. It enables removal of deposits, extending membrane life.
Key functions and benefits
- Flood protection – the Aqua-Stop anti-flood valve helps secure the installation and prevent accidental failures associated with leaks.
- Pressure control – the pressure gauge informs you about the system status and can make it easier to assess when cartridge replacement is approaching.
- Membrane flushing – FR-FLUSH supports better system operation and efficiency because it helps remove deposits from the RO membrane and may extend its service life.
- Ionizer safety – the air-release valve for the REDOX cartridge prevents excessive hydrogen accumulation.
Practical application of the set
The accessories work well as a supplement to an installation where an reverse osmosis system with a REDOX ionizer is operating. Thanks to them, it is easier to monitor device performance, respond to irregularities, and perform basic maintenance tasks that support long-lasting and effective water filtration.
This is especially useful in home installations, where the water filter works regularly and should maintain stable operating parameters for a long time.
FR-FLUSH – how to properly flush the RO membrane
The FR-FLUSH set with BY-PASS is intended for flushing the RO membrane. This process helps wash out deposits and supports proper membrane operation in the reverse osmosis system.
- Membrane flushing frequency – the membrane should be flushed 1–2 times per month during system operation.
- Procedure – open the BYPASS valve for about 2 minutes, allowing the RO membrane to be flushed under high pressure.
- Closing the valve – after 2 minutes, the valve should be closed.
Regular flushing of the osmosis membrane helps reduce deposit build-up and supports maintaining good water filtration system performance. In installations with a REDOX cartridge, it is also worth paying attention to longer periods of non-use, because in such cases the air-release valve plays a particularly important role.
Safe operation and system performance monitoring
The combination of the Aqua-Stop valve, pressure gauge, FR-FLUSH, and air-release valve creates a set that improves daily system operation. The user gains the ability to monitor pressure continuously, service the membrane more easily, and add extra protection against the effects of failure.
In practice, this means more convenient use of the reverse osmosis filter, better control over the operating condition of the installation, and greater peace of mind during everyday use of filtered water.

Questions
What is this REDOX FR-FLUSH accessory set used for?
The set is used to support the operation of a reverse osmosis system with a REDOX ionizer. It helps protect the installation from flooding, monitor pressure, flush the RO membrane, and reduce the risk of excessive pressure associated with hydrogen build-up around the REDOX cartridge.
What is included in the set?
The set includes four items: a pressure gauge, an air-release valve for the REDOX cartridge, an Aqua-Stop anti-flood valve, and FR-FLUSH with BY-PASS for flushing the RO membrane.
How does the Aqua-Stop anti-flood valve work?
The Aqua-Stop valve protects against flooding because, in the event of a failure, it cuts off the water supply to the filter. This is an important element that increases the safety of using the water filtration system.
What is the purpose of the pressure gauge in ANTI-SIPHON VALVE PRESSURE GAUGE FR-FLUSH REDOX RO?
The pressure gauge enables water pressure measurement in RO filters. This makes it easier to monitor system operation and assess whether cartridge replacement is approaching. It can be permanently installed or used for single measurements.
What size tubing is the pressure gauge designed for?
The pressure gauge is designed for a 1/4" (6.4 mm) tube.
How often should the membrane be flushed using FR-FLUSH?
The membrane should be flushed 1–2 times per month during system operation. Regular flushing helps remove deposits and supports longer osmosis membrane life.
What is the RO membrane flushing procedure?
Open the BYPASS valve for about 2 minutes to allow the RO membrane to be flushed under high pressure. After 2 minutes, the valve must be closed.
Why is the air-release valve used for the REDOX cartridge?
The air-release valve is installed before or after the REDOX cartridge. Its purpose is to prevent excessive hydrogen build-up and excessive pressure, especially after a longer break in filter use.
Does the set help extend the life of the osmosis membrane?
Yes, FR-FLUSH enables deposits to be flushed from the RO membrane, which supports better operation and may extend its life. In addition, pressure monitoring helps observe the operating conditions of the entire system.
