Controlling the live flows from the surface Logiball multisize high/low flow inflatable sewer plugs allow for optimal flow control during CCTV inspection, pipe reinstatement or sectional lining. By maintaining the sewer flow active, under control and at a reasonable level, work can be performed downstream without completely blocking the flow or requiring bypass pumping. The active flow is controlled from above ground, with the Logiball High Flow/Low Flow Plug. When inflating the plug, the outer bladder expands and seals the host pipe. A separate controlled air line is used to expand the internal sleeve, similar to a pneumatic pinch valve, which reduces the amount of flow going through the center of the plug. The operator can decide how much water flow is allowed to go through the plug by pressurizing or depressurizing the internal seal from the surface, never having to enter the manhole. By releasing the pressure in the internal sleeve, flow is allowed to go through the plug, reducing the back pressure applied on the plug and allowing for a safe plug removal. Features Logiball High Flow/Low Flow Plugs cannot be used for air testing. Air hoses sold separately.
