Product Description

WATER & FOOD USE: Our innovative Water Flow Restrictor is crafted from premium, safe, and non-toxic materials, making it perfect for various applications. Whether you're using a Household Water Purifier, a Commercial Water Purifier, or Small Reverse Osmosis equipment, our flow restrictor ensures optimal functionality and safety.

SIZE & TUBE COMPATIBLE WITH: Designed to seamlessly fit standard 1/4 RO tubing common in most RO systems (verify your tubing size prior to ordering). For household purifiers, select from 300cc/min for 50 Gallon systems, up to 650CC/min for 200 Gallon systems. For Commercial Water Purifiers ranging from 400Gallon to 800Gallon, choose from 800CC/min, 1200CC/min, or 1500CC/min.

Working Pressure: Exceeds 8kg; with a medium temperature range of 5~50 Centigrade. The product-to-waste water ratio is approximately 1:3, though this can vary based on working pressure and water quality.

EASY INSTALLATION: Enjoy a swift and hassle-free setup, saving both time and costs. Our cutting-edge Non-Locking Clip technology simplifies DIY installation with no tools needed.

What is it?
Our flow restrictor, constructed from food-grade material, facilitates effortless connections and disconnections without additional tools. Its role is to maximize RO water output while minimizing wastewater production. By creating back pressure on the drain line, it efficiently channels water through the membrane and maintains cleanliness. Compatible with standard tubing OD 1/4" Copper, CPVC, PEX, and PVC for most RO systems.

Where to use it?
Ideal for RO systems, beverage dispensers, refrigerator ice makers, and coffee machines. This quick-connect fitting on the wastewater line restricts flow, ensuring membrane cleanliness and balanced brine solution. It also provides back pressure for optimal RO membrane filtration. Upgrade your system effortlessly to accommodate increased usage and alleviate installation headaches.

How to use it?
Install it in the drain line that directs wastewater to the sink. Locate the line connected to your sink drain and splice in the flow restrictor, aligning the arrow for correct direction. To remove, press the outer circle on each end and pull out. Ensure the membrane flow rating matches the flow restrictor for optimal performance. Cut tubing square to prevent leaks, and insert it straight and fully into the connector. Avoid crooked or incomplete insertions to ensure leak-free operation.

FAQ

Q: Which is superior, a single 1*400GPD or two 2*200GPD units?

A: Opt for the 200GPD! Enjoy a more efficient production with reduced glue usage, superior salt rejection, and enhanced water flow.

Q: When should membrane elements undergo cleaning?

A: Membrane elements require cleaning upon encountering any of these situations:

A decline of 10-15% in the normalized permeate flow.

An increase of 10-15% in the normalized permeate's total dissolved solids (TDS).

A rise of 10-15% in the normalized pressure drop between feed and reject streams.

Q: What are the steps to resolve blockage in RO membranes?

A: 1. Begin by confirming whether the home RO System's membrane is genuinely blocked.

2. Investigate the local water quality to determine if scale primarily consists of calcium and magnesium salts.

3. Mix either a 10% hydrochloric acid solution or a diluted descaling detergent, along with a specialized RO membrane cleaning agent, based on scale composition. Submerge the RO membrane in this solution for 24 hours.

4. After soaking, thoroughly rinse the RO membrane using water produced by ultrafiltration. During flushing, ensure the pure water outlet is closed, opening only the wastewater outlet.

Q: Why does the RO membrane experience blockage after just one or two months?

A: 1. High salt content in raw water results in excessive scaling.

2. An overabundance of organic matter fouls and clogs the RO membrane.

3. Elevated RO film recovery rate.

4. Without a flushing function, long-term use leads to high-concentration brine deposits in the RO membrane shell.
