  • Backwater valve seat protector
    Publication number: 20040250863
    Abstract: A hard, durable valve seat or “valve seat protector” is provided in a plastic backwater valve with a flapper valve. The seating is more resistant to wear caused by cleaning, giving it a longer useful life despite the use of a less durable, less expensive plastic material for the rest of the valve and housing.
