How to vent a kitchen sink under a window?

You get assured of an easy process if you follow the guidelines for venting a kitchen sink for a window. But first, you will need to have the doing steps:


Step 1: Measure brick thickness and distance:

Measure and prepare a hole in the wall by measuring brick thickness, the distance of brick from one end to the other, and dispatching brick—re-measure brick length as required for dispatching. Also, measure the thickness of the wall at each height. 

Step 2: Cut according to perfect measurements:

Cut a 2-inch length of 1 1/2-inch PVC pipe with a sharp knife, then bend it to form a section. Insert it through the holes and glue it to the elbow. Glue a second elbow to the other side of the pipe with its outlet facing upward.

Plug the line with sand. Replace the backup valve with a 2″ PVC elbow, wired to a 2-inch threaded hose adapter and a 3/8 “-1/2” threaded access fitting. You’ll add this to your system later, so keep it reasonable as new until you need it.

Cut two 6″-long pieces of 1/ 2″ PVC. Cut one piece of 1/2″ PVC to 2 inches and the other to 6 inches. Cut a 2-inch length of 1 1/2-inch PVC pipe: Cut a 2-inch length of 1 1/2-inch PVC pipe with a sharp knife, and bend it to form a section.

Ns ert it through the holes and glue it to the elbow. Glue a second elbow to the other side of the pipe with its outlet facing upward. Plug the line with sand. Replace the backup valve with a 2″ PVC elbow, wired to a 2-inch threaded hose adapter and a 3/8 “-1/2” threaded access fitting.


Step 3: Draw a line under the window:

Draw a line on the wall by calculating the length of the drain to a point beyond the window. Snap a chalk line to a point beyond the window where the pipe can turn upward.

Use the line height to define the vertical position of a line. The following guidelines will help you to achieve it.

If the line points straight down to the window, it should be about 1/4 inch closer to the window than it usually is. For example, if a fixed line should tell at 25 feet from a point 5 feet away from the window, it should be closer than 10 feet, 1 foot, and 2 feet.


Step 4: Drilling a one ¾ -inch hole:

You will need to make a small hole at one end of the PVC pipe where it meets the wall. Use electrical tape or straighten plumbing pipes with rubber grommets in the line.

Drill a one 5/8-inch hole into the wall’s top plate and extend the Vent into the attic. Route it horizontally to connect to the main vent stack.

Then, drill a hole through that plate. A 2 ¼ -inch metal pipe is set parallel to the Vent, and a 5/8-inch metal pipe is placed perpendicular. The two ¼-inch metal pipe will be the hanger for the gutter cover.

The one 5/8-inch metal pipe mounts the exhaust fan inlet to provide more airflow near the attic floor. A 3/4-inch plastic hose connects from the gutter cover to the exhaust fan. There may be no vent stack in the attic, so you’ll need to install one. 


Step 5: Install vent pipe:

Install vent pipe in the wall by using a screwdriver. Then, use a drill to cut out the line. It would be best to have an opening of about 2 – inches on each side. Glue it to the sanitary tee’s 1 ½ – inch port using PVC cement.

Then take the sweep elbow and place it to the pipe. Once this is done, you can take out the top flange. You should now have two pieces of pipe that form a square with each other. 

Step 6: Attaching pipe into the hole:

Use a drill or screwdriver to place the vent pipe in the small opening you made in the wall. You will need to slip a piece of tape on top of the vent pipe and tighten it with your screwdriver.

Start by positioning the vent pipe to see it through the Vent. It should be placed next to the wall to look into your attic. It is best if your vent pipe is oriented towards the center of your home because this will give you a better view of what’s happening inside and help reduce noise levels.

How far can a kitchen sink be from a vent?

The Vent can’t be more than 1 1/2 feet from the Trap if the waste line is 1 inch. The critical distance is 2 feet. The web’s minimum diameter for receiving traps is 2.5 feet.

A minimum of two trap sizes are recommended to avoid overloading the hitch with waste from one size and robbing it due to increasing its volume by filling a larger space than was intended.

Trap capacity is affected by the mass load on top of the Trap (weight and water), so use the weight test data provided on the Trap’s datasheet.

A 500-pound weight placed on top of a 1,000-pound trap will increase its capacity by about 1/3—the guidelines for setting traps are:1. Place the waste line parallel to and as close to the Trap as possible, one foot from the bottom of the trap body; be sure that all other parts.


Can a vent pipe run horizontally?

 Can vent Pipelines be installed horizontally as long as you remember,

Any vent pipes must be appropriately positioned, so they do not block the drainpipe. To ensure that the vent pipe is vertical and not tilted up or down, you can use a hose clamp on the end of the vent pipe.

You have to be careful because if you wrap your hand around it, it could damage your skin or cause an injury. If a grate is used for drainage for any roof


What should be the distance between the vent and the trap?

Thirty inches is the maximum distance from the Trap to your Vent.
