Compression type joints for hub and spigot cast iron soil pipe shall be made with foam insert gaskets in accordance with ASTM C564. True or False?

  1. True

  2. False

The correct answer is: False

Compression type joints for hub and spigot cast iron soil pipe are required to be made with a substance other than foam inserts. ASTM C564 actually specifies the use of flexible elastomeric gaskets for compression type joints. Foam inserts are not suitable for this purpose as they may not provide the necessary sealing properties to ensure a watertight joint. Therefore, the correct answer is False.
