Understanding the Components of Your Sink Waste System

Before we jump into the installation process, it's essential to acquaint ourselves with the key components of your sink waste system. Here's what you need to know:

  • Sink Drain: The exit point for wastewater from your sink. Sink drains may have slight variations depending on the sink model and manufacturer.
  • Gasket: A rubber or foam gasket provides a watertight seal between the sink drain and the waste pipe.
  • Overflow Pipe: Prevents water from overflowing the sink, directing it into the waste system. The type of rubber seal used depends on the sink's shape, whether round or square.
  • Sink Trap: The sink trap plays a pivotal role in preventing sewer gasses from entering your kitchen. Some sink traps come with an extra spout for connecting a washing machine or dishwasher hose, like our Brushed Brass Kitchen Sink Waste with Trap.

Step-by-Step Guide to Kitchen Sink Waste Installation

Let's now walk through the meticulous process of installing your kitchen sink waste system:

  1. Attaching the Sink Waste: Begin by positioning the sink drain underneath the sink, ensuring that the hole faces the overflow drain. Place a rubber or foam gasket on top of the sink drain. Carefully align the top drain over the gasket and secure it with the provided long screw. Take your time to avoid scratches or dents on the sink's surface.

  2. Connecting the Overflow Pipe: Depending on your sink's shape (round or square), select the appropriate rubber seal for the overflow pipe. For example, our Copper Basket Strainer Waste and Square Overflow is perfect for square-shaped overflows. Press the rubber seal onto the square section leading to the pipe. Hold the seal in place while threading a screw through from the sink side to secure it.

  3. Adding the Sink Trap: Install your sink waste trap, ensuring a secure connection to the sink drain. Sink traps often come with an additional spout, perfect for connecting a washing machine or dishwasher hose.

  4. Attaching the Washing Machine or Dishwasher Hose: To connect your appliance's hose to the sink trap, use a jubilee clip to ensure a secure and leak-free connection. Tighten the jubilee clip using a screwdriver for added peace of mind.

  5. Working on the Waste Pipe: Depending on your specific setup, you may need to cut and adjust waste pipes and elbows. Ensure that your waste pipe maintains a gentle slope (1cm in 40cm) to promote efficient drainage and prevent odors.

  6. Completing the Installation: Once all components are in place, add pipe clips to secure the waste pipes and prevent accidental knocks. For a reliable strainer sink waste, consider our Brushed Black Basket Strainer Kitchen Sink Waste.
