Main Drain Line

The main drain line serves as the central pipe that carries wastewater away from the kitchen sink. It connects to the individual sink drains and leads to the sewer or septic system. Proper slope and alignment are crucial for efficient water flow.

Individual Sink Drains

Each sink in a double kitchen sink setup has its own drain pipe. These individual sink drains collect water and debris from their respective sinks and feed into the main drain line. They should be properly connected to prevent leaks and ensure smooth water flow.

P-traps

P-traps are curved pipes located below each sink’s drain. They hold water in their bends, creating a water seal that prevents foul odors from traveling back up through the drain. P-traps also trap debris, preventing it from entering the main drain line and causing clogs.

Ventilation Pipes

Ventilation pipes are vertical pipes connected to the drain system. They provide a means for air to enter the plumbing system, equalizing pressure and preventing water traps from being siphoned. Proper ventilation helps maintain optimal drainage and prevents gurgling noises.

Step 1: Measure and Plan

Before starting the installation, measure the available space under the kitchen sink cabinet. Plan the layout of the drain system, ensuring sufficient slope for water flow and allocating space for the P-traps and ventilation pipes.

Step 2: Cut Openings in The Cabinet

Using a saw or drill, carefully cut openings in the cabinet to accommodate the drain pipes and fittings. Ensure the openings are positioned correctly based on your planned layout.

Step 3: Install The Main Drain Line

Connect the main drain line to the existing plumbing system. Use appropriate fittings and secure the connections tightly to prevent leaks.

Step 4: Connect The Sink Drains

Attach the individual sink drains to their corresponding sinks. Use the appropriate fittings and ensure tight connections. It’s essential to create a gentle slope from the sink drains to the main drain line to facilitate proper water flow.

Step 5: Install The P-traps

Install P-traps below each sink drain. Ensure the P-traps are properly aligned and tightly connected to prevent leaks. Make sure the water seal is intact by filling each trap with water after installation.

Step 6: Install Ventilation Pipes

Connect ventilation pipes to the main drain line or individual drain pipes. These pipes should extend vertically and terminate above the roofline to allow for proper air circulation and prevent pressure imbalances.

Clogs and Blockages
