This picture actually shows two products that were installed as part of our system. The grey rectangle is actually a vent cover, which creates a seal around existing vents so that outside air cannot get into the crawlspace. The product on the right-hand side of the photo is IceGuard. This is a part of the discharge line of the sump pump and is installed on the outside so that if the outside line freezes up, the water is still able to get outside.
