Description
This valve is typically installed in homes or buildings with basements, cellars, crawl spaces, or areas that are accessible for servicing. The normally open gate allows the sewer system to ‘vent’ any gases that may be caused by positive or negative pressures in the sewer line. The 4963 has a ‘Clear View’ top that makes inspection of the valve quick and simple for the building owner or plumber! As well, the 4963 comes with an integral clean-out for rodding the sewer lateral. Should rodding from the stack be necessary, the snake can easily pass over the open gate and be retracted without harming the components.
