Wafer-Type Valves are installed to minimize interference with which of the following?

• A. Installed without interfering with system components
• B. Installed with additional support brackets
• C. Must be required to be listed
• D. Only used in commercial buildings

Answer: (A)

Wafer-type valves minimize interference with surrounding system components. Their compact, blade-like body sits between two flanges and doesn’t protrude into the surrounding space, which keeps access clear and allows closer, tighter piping layouts. This helps avoid clashes with hangers, insulation, adjacent fittings, or other nearby components, making installation in residential, space-constrained designs easier. They aren’t about needing extra support brackets or being limited to commercial buildings, and they don’t imply any mandatory listing differences—their main advantage is the reduced physical footprint that interferes least with the rest of the system.
