Hancor's sump pump well is manufactured with a molded lid that incorporates the twist-lock mechanism, allowing easy entrance and a secure close to the sump well. The lid makes old rusted bolts a thing of the past. The well is molded from heavy-duty polyethylene for light weight and strength. It is completely corrosion proof and resistant to acid, alkali and frost. It will not crumble, break or rust. Three pre-formed inlet collars accept 4 in corrugated polyethylene drainage lines from inside the basement perimeter or floor drains. These lines snap on the collars quickly and easily. A molded-in panel on the side of the sump (which normally faces the basement footer) is designed for accepting the outside basement perimeter drainage line at the height desired.
