Just had a new Weil Mclain Ultra 155 gas boiler installed as well as a Weil Mclain 60 Indirect hot water tank. When ever the water in the house or spinklers are being used, there is a rattle inside the tank. When we use the cold water only, it still makes noise.
Anyone have any ideas? Im thinking this should not be and it may be a defect from the factory. Any info would be greatly appricated.
