with a new home even with a properly installed drain system something can get blocked, like a drain line filling with silt, i dug it up and saw that first hand
water flow in area may change. this happened to a buddy who suddenly had a wet lawn and water in basement, where none had existed before. 3 years later the water line leak 1/2 mile away must of got worse, anyhow after that was fixed his yard and basement got dry again........
nothing in life is for sure except in your world you must be rich to replace anything that breaks
