Witt Lining - Manways & Sumps

It is most desirable to install these access ports at the factory. The location of the manway is critical. Bolt holes are punched or drilled in the field to ensure that they are placed in the proper location. The manway should not be used to lift or support the liner. Sumps are installed during liner fabrication. Correct dimensions and location of the sumps are important for a proper fit.
