Buying Guide
- What drain size do I need? Most kitchens use 1-1/2″ drains. Confirm existing fittings before purchasing a kit to avoid mismatches with wall or floor connections.
- Single vs. double sink? For double sinks, choose a kit that includes a tee or double-outlet components to connect both bowls efficiently.
- DIY vs. professional installation? If you prefer DIY, look for kits with clear instructions, illustrated diagrams, and universal fittings.
- Material and seal components? Prioritize PP, PVC, or other durable plastics with quality washers and slip-joint nuts for leak resistance. Avoid weak joints in high-usage areas.
- Disposal and dishwasher connections? If you have a disposal or dishwasher, ensure the kit accommodates those connections, including outlet sizing and Tee or reducer options.
- Space and accessibility? Some kits are space-saving or adjustable to fit tight cabinets. Consider the cabinet depth and wall/outlet placement before buying.
