How do I choose the correct replacement parts for my commercial sink’s drain valve? Follow this checklist to ensure compatibility:

• Measure the valve diameter​​ (common sizes: 1.5″, 2″outlet).
• ​​Identify the mounting type​​ (threaded, slip-on, or solvent-weld connections).
• Confirm the waste outlet height​​ (standard is 3.5″, but some sinks vary).
• ​​Check the handle style​​ (twist WV-3170, lever WV-3180, or automatic).
