Elms Weeping Tile

Bought our house 5 years ago and Elms did the weeping tile (NEW CONSTRUCTION). Had 3 inches of water in the basement the first Spring. Have asked Elms to come out on 3 separate occasions, they say they are coming, but never show up. Our Local plumbing company finally tells us that there is no pipe into the sump pit from the weeping tile. Fairly important detail, you would think. My advice on new construction is to decline the Alberta New Home Warranty so that you can at least sue the builder and companies privately. ANHW is in place to protect the builders, not the buyers.
