What are the Steps to Plumb a Double Sink?

Plumbing a double sink involves several steps to ensure proper installation and functionality. Here’s a simplified guide to help you through the process:

1. Gather Your Tools and Materials:

• Pipe wrench
• Adjustable pliers
• Screwdriver
• Pipe joint compound
• Plumber’s tape
• Drain assembly kit
• PVC pipes and fittings
• Trap adapter

2. Shut Off the Water Supply:

Turn off the water supply to your kitchen. This is usually done under the sink or at the main water valve.

3. Remove the Old Sink and Plumbing:

Disconnect the existing sink and drain pipes. Remove any old sealant or putty from the sink opening.

4. Install the Sink:

Place the new double sink into the countertop opening. Secure the double sink in place according to the manufacturer’s instructions.

5. Install the Drain Assembly:

• Install the drain strainers into the sink basins.
• Connect the tailpieces to the strainers, ensuring a tight fit.
• Use plumber’s tape or pipe joint compound to secure the connections and prevent leaks.

6. Connect the Drain Pipes:

• Measure and cut PVC pipes to connect the drain assembly to the existing plumbing.
• Use trap adapters to connect the pipes to the existing trap and ensure proper alignment.
• Secure all connections with slip nuts and washers. Hand-tighten them and then use a wrench to ensure a snug fit without overtightening, which could damage the pipes.

7. Test for Leaks:

• Slowly turn on the water supply and ensure there are no leaks at all connections.
• Tighten any fittings if necessary to eliminate leaks.

8. Install the Garbage Disposal (if applicable):

If you have a garbage disposal unit, follow the manufacturer’s instructions to install and connect it to the drain assembly.

9. Seal Around the Sink:

Spread a line of silicone sealant along the perimeter of the double sink to establish a waterproof seal between the double sink and the countertop.

10. Reconnect the Dishwasher (if applicable):

If your dishwasher drains into the sink, reconnect the drain hose to the disposal or drainpipe according to the manufacturer’s instructions.

11. Check for Proper Drainage:

Test the sinks by running water and checking the drainage. Ensure water flows smoothly and doesn’t pool in the basins.

By following these steps and paying attention to detail, you can successfully plumb a double sink in your kitchen, ensuring efficient and leak-free operation. If you’re unsure at any point, don’t hesitate to consult a professional residential plumber for assistance.
