Symmons manufactures every replacement part whether it is for a faucet an anti-scald, pressure-balancing shower valve or any of our other products, to the same exacting standards that it maintains with the parts that go into its original equipment to ensure that the repair parts will return the product to its original working condition. While many generic parts may appear to be similar to the original Symmons parts, but they do not hold to the same exacting tolerances that we do. Also the use of parts other than Symmons Genuine Replacement Parts will void our warranty.
