Cleaning And Inspecting The Drain

When it comes to maintaining your kitchen sink, it’s essential to pay attention to the drain as well. Cleaning and inspecting the drain is a crucial part of ensuring the proper functioning of the kitchen sink. This process involves removing the drain flange and conducting a thorough examination of the drain to identify any potential issues that may affect its performance. In this section, we will delve into the steps involved in cleaning and inspecting the drain to help you keep your kitchen sink in top condition.

Clean The Drainpipe

One of the first steps in cleaning and inspecting the drain is to focus on the drainpipe itself. Begin by clearing out any debris that may be present in the drainpipe. This can be accomplished using a plumbing snake or a drain auger to dislodge and remove any obstructions that may be causing a blockage. Additionally, you can use a biodegradable drain cleaner to help break down any organic matter that may be contributing to clogs in the drainpipe.

Inspect The Drain For Any Damage

After cleaning the drainpipe, the next step in the process is to inspect the drain for any signs of damage. This involves visually examining the interior of the drain using a flashlight to look for any cracks, corrosion, or other issues that may be affecting the drain’s performance. It is essential to check the rubber gasket and seal for any signs of wear and tear, as these components play a crucial role in preventing leaks and maintaining the proper functioning of the drain.

Installing A New Drain Flange (optional)

Installing a new drain flange is an optional step in removing a kitchen sink drain flange, but it can be a good idea to do so if the old flange is damaged or worn out. Installing a new drain flange can help ensure a tight seal and prevent leaks in the future.

Apply Plumber’s Putty To The New Drain Flange

Before securing the new drain flange in place, you’ll need to apply the plumber’s putty to create a watertight seal. Plumber’s putty is a soft, moldable substance that is commonly used in plumbing projects. Here’s how to do it:

  1. Take a small amount of plumber’s putty and roll it between your hands to create a thin, rope-like shape.
  2. Place the putty around the bottom edge of the new drain flange.
  3. Gently press the drain flange onto the sink drain opening, making sure the putty is evenly distributed.

Secure The New Drain Flange In Place

Once the plumber’s putty is applied, you can secure the new drain flange in place. Follow these steps:

  1. Place a rubber gasket onto the drain flange, ensuring it is centered over the sink drain opening.
  2. Insert the new drain flange into the sink drain opening, aligning the holes in the flange with the corresponding holes in the sink.
  3. From underneath the sink, thread the mounting nut onto the drain flange, tightening it by hand until it is snug.
  4. Using a pair of pliers, tighten the mounting nut further to ensure a secure fit, but be careful not to overtighten and risk damaging the sink or the flange.
  5. Finally, wipe away any excess plumber’s putty that may have squeezed out from beneath the flange using a damp cloth.

That’s it! You have successfully installed a new drain flange in your kitchen sink. With a properly installed drain flange, you can have peace of mind knowing that your sink will remain leak-free for years to come.
