How to Install Basin Drain

Prepare the Sink Area

  1. Clear the Work Area: Ensure the sink area is clear of any debris, objects, or clutter that may obstruct your work.
  2. Turn Off Water Supply: Locate and close the water shut-off valves beneath the sink to cut off the water supply. This step is crucial for safety and to prevent any accidental water leaks during installation.

Remove the Old Drain

  1. Disconnect Water Supply Lines: Use your adjustable wrench to disconnect the water supply lines connected to the old drain. Place a bucket or towel beneath the connections to catch any residual water.
  2. Remove the P-Trap: If your sink has a P-trap assembly, disconnect it to gain access to the old drain.
  3. Loosen the Locknut: Beneath the sink, locate the locknut securing the old drain to the sink. Use your basin wrench to loosen and remove it. Be cautious not to apply excessive force, as it may damage the sink or plumbing.
  4. Remove the Old Drain: Carefully lift the old drain assembly out of the sink. Be prepared for any residual water inside the drain to drain into the bucket or towel.

Clean and Prepare

  1. Clean the Sink: Thoroughly clean the sink’s drain opening, removing any residue, old plumber’s putty, or debris. Ensure the surface is clean and smooth.
  2. Apply Plumber’s Putty: Roll a small amount of plumber’s putty into a rope-like shape and apply it evenly around the underside of the new SR Sunrise drain flange. This putty will create a watertight seal when you install the new drain.

Install the New Drain

  1. Insert the Drain: Carefully insert the new SR Sunrise drain assembly into the sink’s drain opening, ensuring it fits snugly. Press it down gently to evenly distribute the plumber’s putty.
  2. Secure with the Locknut: From beneath the sink, locate the drain tailpiece protruding from the new SR Sunrise basin drain. Thread the locknut onto the tailpiece and tighten it using your basin wrench. Make sure it’s snug but not overly tight to avoid damaging the sink or drain.
  3. Wipe Away Excess Putty: Clean any excess plumber’s putty that may have squeezed out from under the flange. A clean surface ensures a neat appearance and a watertight seal.

Connect Pipes

  1. Reattach the P-Trap: If you removed the P-trap, reattach it to the new SR Sunrise drain’s tailpiece and the existing plumbing. Ensure all connections are secure but not overtightened.
  2. Reconnect Water Supply Lines: Reconnect the water supply lines to the corresponding hot and cold water inlets on the new SR Sunrise basin drain. Tighten the connections securely using your adjustable wrench.
  3. Check for Leaks: Turn the water supply back on by opening the shut-off valves beneath the sink. Check all connections, including the newly installed SR Sunrise basin drain, for any signs of leaks. If you notice any leaks, tighten the affected connections as needed.

Test and Finish

  1. Operate the Drain: Test the new SR Sunrise basin drain by running water into the sink and observing its drainage performance. Ensure that water flows smoothly without any blockages.
  2. Check for Leaks: Once again, inspect all connections for any signs of leaks. Address any leaks promptly by tightening the affected connections or applying plumber’s tape if necessary.
  3. Clean Up: Remove any tools, towels, or buckets from the area, and clean up any residual debris or water. Leave the sink area clean and tidy.
