What is used to connect a new water main to an existing water main?

• A. Repair clamp
• B. Volute
• C. Saddle
• D. Coupling (such as Dresser)

Answer: (D)

The correct answer is coupling (such as Dresser) because it is specifically designed to connect two sections of pipe, including joining a new water main to an existing one. Couplings provide a secure and leak-proof connection, accommodating any minor misalignments and allowing for movement due to thermal expansion or ground shifts. They are an essential component in water distribution systems, ensuring that water can flow seamlessly from the new main into the existing infrastructure. Repair clamps, while useful for temporarily fixing leaks in existing pipes, are not intended for new installations or connecting new mains to existing ones. Volutes are components related to the hydraulic design of pumps and do not serve the purpose of connecting pipes. Saddles can be used in certain scenarios to facilitate tapping into an existing main; however, they are not the standard method for connecting new mains and may not provide the robust connection needed for larger diameters or high-pressure applications.
