What type of fitting should be used for sewer connections?

The sanitary type fitting is the appropriate choice for sewer connections due to its design, which ensures smooth flow of wastewater and minimizes the potential for clogs and blockages. Sanitary fittings typically have a larger radius at bends, allowing for the efficient transport of sewage without creating turbulence that could lead to the accumulation of solids. This type of fitting is essential in maintaining proper drainage in sewer systems and helping to prevent health hazards associated with sewage backflow.

In contrast, the other types of fittings do not possess the same characteristics suitable for sewer applications. Standard fittings, for instance, may not adequately support the specific flow dynamics required in sewage systems. Heavy-duty fittings, while robust, may not be specifically designed for sewer applications, lacking the necessary smooth transitions. Common type fittings tend to be generic and are typically not engineered to handle the unique demands of sewage transport. Thus, sanitary type fittings are specifically crafted to provide the best performance for sewer connections.
