The two white IceGuard's shown in the picture is an anti-freezing system for sump pump discharge lines. Sump pump discharge lines can freeze.Pipe terminations can become covered with snow and ice in the winter. This can spell disaster for your basement if the sump pump water cannot exit the line outside.
The IceGuardĀ® system allows water to escape from a sump pump discharge line if the pipe freezes or becomes blocked for any reason. Even if the pipe outlet is buried under a foot of ice and snow, the water can escape, allowing your sump pump to keep your basement dry.
