In a large saucepan, brown the bacon. Add the leeks, carrots, garlic, and butter and sauté gently for about 5 minutes or until the carrots are tender. Season with salt and pepper. Sprinkle with the flour and stir to combine. Add the milk and broth and bring to a boil, stirring constantly. Simmer gently for about 3 minutes. Adjust the seasoning. Remove from the heat. Add the seafood, potatoes, and parsley. Pour into a large 25-cm (10-inch) in diameter and 5-cm (2-inch) high pie plate. Set aside.
Egg Wash
In a bowl, combine the egg and water. Set aside.
On a floured work surface, roll out the dough into a 30-cm (12-inch) disc. Make an incision in the centre of the pastry.
Moisten the rim of the pie plate so that the pastry dough adheres well. Place the dough over the filling and press the edges on the dish to seal. Brush with the egg wash. Place on a baking sheet and bake for about 45 minutes or until the crust is golden brown. Let stand for 15 minutes before serving.
