Flood-Guard floor drain check valve
Posted by dickg on March 10, 19101 at 10:38:09:
I've purchased a 3" Flood-Guard check valve for my basement floor drain, but I can't get it to expand enough to fit tightly. My floor drain is a 3" PVC pipe cut off flush with the floor. There is a stamped metal grate that just sits over the opening with four tabs bent down inside the pipe to keep it from sliding around. Is this not a typical floor drain configuration? Is there something that I could cement inside the pipe to reduce the diameter enough to accomodate the Flood-Guard? Un-expanded it is about 2-15/16" in diameter. Thanks.
