The flood barrier has a minimal maintenance frequency requirement, conducted every 6 to 12 months. A thorough inspection of the unit is conducted including; hydrostatic testing, inspection of leakage of seals at the base of the rising flood wall, visual inspection of seals at the ends of the flood wall, replacement of cracked or perished seals, checking of the oneway valve in the service pit, verification of alarms connected to the building manager, and cleaning of structure gratings from debris and silt.

Hydrostatic testing of the Hyflo SCFB unit operation should preferably be carried out when there is minimal pedestrian and vehicle traffic, to avoid incidents and damages. This is done simply by filling each Hyflo Self-Closing flood barrier unit with water. The total test duration depends on the filling rate of the water supply. Each unit system installed has a warranty against fabrication and installation faults that includes incurring leakage of more than 0.1 l/mtr/min.

Each Self-Closing Flood Barrier unit needs a service pit for controlling the water inlet and the drain. Part of the maintenance plan is to check and assess if all parts of the service pit are working well. The type of service pit depends on where the Self-Closing Flood Barrier will be installed. A standard service pit is necessary when the surface area of the body of water is lower than the surface area of the bottom of the barrier. This setup is sufficient to drain the service pit by itself. A pump should always be included in the flood barrier unit if the surface area of the body of water is higher than that of the flood barrier. This helps to facilitate faster drainage of the unit.

A cost-effective, time-saving and practical solution for potential flood problems the Hyflo SCFB Self-Closing Flood Barrier is the safe choice in flood protection.
