WaStop® Inline Check valve
The city heard the residents’ complaints and replaced the flap with a WaStop inline check valve. The WaStop is self-cleaning and requires virtually no maintenance. Due to its unique pulsating flow action, the valve is self-cleansing ensuring mud and other debris is keep clear of the outfall enabling the stormwater to run off the road and nearby property whilst stopping tidal backflow. Since the installation the property has not flooded and the over-joyed home owner has a vibrant lawn and does not need to risk cleaning the outlet. He and his neighbors can now sleep soundly during a rain storm.
Four years post installation, Emily Demore, Assistant Stormwater Manager, confirmed that the valve was still functioning without issues, and does not require maintenance. This saves enormous costs for the Town freeing up resources for other issues facing the Town of Mt Pleasant.
The installation was in fact so successful that another nearby homeowner invested in a WaStop to protect his home and lawn against tidal flooding. The instant protection provided by WaStop, along with the low maintenance was deciding factors. Just four days after order the WaStop the homeowner was protected.
