Since 1939, this commitment to top quality offers you years of service and durability provided by a family owned company with product made in the USA. Our standard 1-1/2 inch inline check valve that threads directly into a pump’s discharge for basement sump and drain pump applications. The rubber coupling with stainless steel clamps allows for easy connection to SCH40 PVC. In low clearance applications, this is an ideal check valve because the vertical space required to install it is minimal. Additionally, the check valve includes a pre-drilled weep hole to prevent the pump from becoming air-locked. Peace of mind right out of the box!
