FR-FLUSH Set for rinsing reverse osmosis membranes. It allows for quick rinsing under higher pressure through a bypass, which helps remove deposits and limit the accumulation of contaminants. Easy installation to the existing flow restrictor, includes clips for securing quick connectors. Fits RO membranes up to 150 GPD, 2 x 1/4" JG type quick connectors.
The FR-FLUSH osmotic membrane flushing set is a practical solution for RO installations such as reverse osmosis, an osmotic filter, or a home reverse osmosis system. It enables quick membrane flushing by bypassing the flow restrictor, helping remove deposits, reduce contaminant buildup, and support longer, stable operation of the osmotic membrane. It is a simple-to-install service component for a water filtration system, compatible with RO membranes up to 150 GPD.

The FR-FLUSH set is designed for quick membrane flushing in reverse osmosis systems. The solution works on a BY-PASS principle, meaning it bypasses the flow restrictor. When the valve is opened, water can flow freely to the drain, allowing deposits accumulated on the membrane to be effectively rinsed out.
Regular use of the set supports maintaining the efficiency of the reverse osmosis filter and helps reduce contaminant buildup. In practice, this means more convenient system operation and better protection of the membrane against premature wear.
The kit is intended for RO systems used as a water filter and a water treatment element in a home or workplace. The set is compatible with all RO membranes up to 150 GPD, making it a convenient addition to many popular installations based on an osmotic filter.
Thanks to the 2 x 1/4" JG quick connectors, installation is simple, and the set can be easily integrated into an existing installation with a flow restrictor.

The set does not include a flow restrictor. Install your existing restrictor or purchase a new one.
Such periodic flushing is a simple maintenance task that helps keep the osmotic membrane in good condition and supports the proper operation of the entire reverse osmosis system.
During everyday operation of the system, the valve should remain closed. Open it periodically only for membrane flushing.
In RO systems, the membrane is responsible for the key stage of water filtration. During operation, contaminants and deposits can accumulate on its surface. The FR-FLUSH set helps rinse them out in a simple way, without complicated service procedures.
This is a practical solution for users who want to take care of their reverse osmosis filter, maintain good water filtration system performance, and reduce the risk of faster membrane wear.

| Parameter | Value |
|---|---|
| Product type | RO osmotic membrane flushing set with BY-PASS |
| Quick connector size | 2 × 1/4″ JG type |

The set is used to flush the osmotic membrane in RO systems. When the BY-PASS valve is opened, it allows water to flow freely to the drain, helping remove deposits from the membrane.
The recommended frequency is 1–2 times a month during RO system operation. This regularity helps reduce contaminant buildup and supports a longer membrane lifespan.
After opening the BY-PASS valve, allow the flow for about 2 minutes, then close the valve. This is enough to rinse deposits from the membrane.
The set is compatible with all RO membranes up to 150 GPD. Before installation, make sure the system uses connections compatible with 2 × 1/4" JG quick connectors.
No. The set does not include a flow restrictor, so you should use your existing restrictor or install a new one matched to the system.
The existing restrictor should be moved to the red hose of the FR-FLUSH set. If necessary, the hose should be cut so that the restrictor fits securely and stably.
In normal operation, the ball valve with the blue handle should be closed. It is opened only for periodic membrane flushing.
Regular flushing helps remove deposits, reduce contaminant buildup, and support a longer membrane lifespan. It is a simple way to maintain the efficiency of the reverse osmosis system.
