In case, the sink isn’t sufficiently ventilated, it gets hard to drain the water. This means that the water becomes stuck within the drain pipes and the wastes to be eliminated aren’t efficiently removed out of the drain pipes.

Follow the below recommendations and you are guaranteed a simple procedure.

Items you will need:

  • Hacksaw
  • Drill PVC sanitary tee of 2 x 2 and 1 x ½ – inch
  • Chalk line
  • Tape measure
  • Three long-sweep elbows of 1 x ½ – inch
  • PVC cement
  • Hole saw of 1 x 5/8 – inch

Step 1. Mounting a Sanitary Tee

In the sink drain line located within the wall hollow, mount the sanitary tee. The sanitary tee must not be mounted with a length that is longer than three and one-half feet from the lower part of the P-trap.

The PVC sanitation tee is also recommended to be utilized for a 2″ waste line. Make use of PVC cement in order to join the pipe that is coming out of the kitchen sink and sanitation tee.

The drain’s continuation must be secured to the opposite end of the sanitary tee. Also, make sure that the port that is 1 1/2 inches is facing up.

Step 2. Join the PVC Pip

Use a tape measure to take measurements of the PVC pipe to be up to 2 inches long. Use a hacksaw to trim the measured pipe.

With the cement made of PVC connect it to the sanitary tee’s 1 ½” port. Next, grab the sweep elbow and locate it to the pipe. Make sure that it faces straight at the wall. After that, you can attach it to the pipe.

Step 3. Draw an Extension of the Line Beyond the Window

Take a look at the window in the kitchen above the sink. Locate a point outside the window at which the pipe will be going vertically.

Then connect the chalk line to that point. The slope upwards of the line cannot be less than 1/4 inch per foot. For example, when the place you’ve determined is located 2 feet from an elbow then the line must rise no less than 1/2 inch.

Step 4. Make Holes into Studs

Make utilize of a drill as well as a hole saw for drilling holes of 1 5/8 into studs, between an elbow to the place at which the kitchen sink vent is raised. Each hole must be placed on the line.

Step 5. Trim 1 1/2 Inches Length of Pipe

Get the 1 ½ inch pipe and trim it into the length that is the range between the elbow and the point at which the vent is raised.

After this insert it gently into the holes you drilled in step 4. Once you’re done, you can take PVC cement and stick the pipe to the elbow.

Take another elbow and glue it to the pipe’s opposite side. Check that the outlet is upward.

Step 6. Connect the Vent Pipe to the Stack

This is the final step to installing a vent pipe for the kitchen sink under the window. On top of the wall, use the drill to create one 1 5/8 inch hole.

Via that hole, expand the vent to get to the attic. Join it to the main vent stack and located it horizontally on the stack. Utilizing a stack fitting to reduce sanitation tee, join the new vent to an existing central vent stack.

However, as you follow the steps above, the next tips are important to keep in your mind.

> While you are creating your new vent through the attic, make sure you maintain the slope to not less than 1/4 inch for each foot.
> In the event that your main vent or other existing vents in use are made of PVC pipes, utilize identical PVC pipes to construct the vents for your kitchen sink. Then, join the pipes using identical PVC glue rather than other glues.
