QUICK-FIT CHECK VALVE 1/4" 6MM | 3/8" 10MM INLINE REVERSE OSMOSIS WATER FILTERS

Quick-Fit Check Valve 1/4" - Reverse Osmosis Filter Quick-Fit In Line Check Valve

Standard RO system part and can be used to replace any non functioning pure water line check valve | Used in conjunction with a 4-way shut off valve to stop RO waste flow which we sell separately here and is pictured in the 2nd listing image of this listing but not included with this listing which is for the non return valve only

According to regulatory standards any water filter system under constant water pressure [regardless of the brand or supplier] is required to be fitted with an AS3497 approved pressure reducing valve and back-flow prevention device which we have listed separately in our store. We also recommend that a leak detector shut off device is installed with any water filter and / or reverse osmosis system which is under pressure and is also for sale in our store.

hy Choose the Quick-Fit Check Valve?

This Quick-Fit Check Valve (Non-Return Valve) is a standard and essential component for Reverse Osmosis (RO) water filter systems. Its primary function is to act as a one-way valve, preventing purified water from flowing back out of the RO membrane or the storage tank. This is crucial for maintaining system pressure and ensuring the RO waste flow stops when the 4-way shut-off valve closes.

Compact Design and Powerful Performance

This check valve features a quick-fit push-in connection design for easy, tool-free installation and is available to fit two common tubing sizes: $1/4\text{in}$ ($6\text{mm}$ OD) and $3/8\text{in}$ ($10\text{mm}$ OD). It serves as a direct replacement for any non-functioning pure water line check valve in a standard RO system. It works in conjunction with a 4-way shut-off valve to properly control the system's operation, though the 4-way valve is sold separately.

Seamless Integration and Safety/Delivery Notes

This valve integrates directly into the pure water line of your RO system. A delivery note is provided, warning that selecting the option without tracking means the seller cannot provide updates or an Estimated Time of Arrival (ETA) after dispatch. Furthermore, the description reminds customers that any water filter system under constant pressure must be fitted with an AS3497 approved pressure reducing valve and back-flow prevention device for regulatory compliance. Installing a leak detector shut off device is also highly recommended for all pressurized water filter or RO systems.
