Tideflex® TF-1 Check Valve Solves Stormwater Run-Off Challenge in Northern Ireland
One of the largest manufacturers in Northern Ireland—and a major player in the UK aerospace industry—had a specific requirement for the design of their new Belfast plant. They needed at least half of the stormwater runoff from their massive 600,000 sq. ft. (55,742 m²) facility roof to drain directly into the Conn’s Water Estuary through a 1500mm concrete outfall pipe.
Because the Conn’s Water Estuary is tidal, it was essential to install a non-return check valve that could provide reliable, long-term protection against backflow. They were particularly concerned about the risk of blockages from mud, silt and debris, which could seriously impact the drainage system’s performance. That is when they turned to Red Valve for a solution.
After evaluating the conditions, the team selected the Tideflex® TF-1 Duckbill Check Valve as the best fit for the job. Designed to handle challenging environments, the TF-1 is ideal for tidal areas prone to debris and offers dependable, virtually maintenance-free backflow prevention—even when access is limited.
An 1840mm Tideflex® TF-1 Valve was installed on the outfall pipe to Conn’s Water, and it’s been performing flawlessly ever since. Its unique one-piece construction—made entirely of fabric and elastomer—means it won’t rust, corrode, freeze or warp. Plus, it has no mechanical parts that can break, stick or catch debris, which eliminates many common failure points. Even better, the valve naturally clears itself of debris and can seal around small objects with as little as one psi of backpressure.
The TF-1 operates using just the pressure of the water itself to open and close—no external power is needed. Its low cracking pressure means water drains easily from the roof without pooling, and because it doesn’t need lubrication or regular maintenance, it offers a long-lasting, worry-free solution.
Since being installed, the Tideflex® TF-1 Check Valve has delivered exactly what the project required: reliable, maintenance-free backflow prevention in a tough tidal environment.
