Let’s get started.
Why do you vent a washing machine drain pipe?
Venting a washing machine drain pipe is important because it allows air to enter the pipe as water is draining out.
This prevents vacuum formation and ensures that the water drains out completely.
If you have noticed, the end of the washing machine drain hose is usually connected to a Tee fitting.
And if you look carefully, you’ll see that “T” is attached to two different lengths of drain hoses.
If you don’t vent a drainpipe, the water will have nowhere to go and will start to come back into your washing machine.
This can cause all sorts of problems, from leaks to floods.
So it’s important to make sure that you vent your drainpipe properly.
If you have a washing machine drain pipe that is not vented, you may experience problems with your washer.
How To Vent A Washing Machine Drain Pipe?
If you are not familiar with the process of venting your washing machine drain pipe, then you may simply follow the below steps that will make your task easy.
So, there are 2 methods to vent the drain pipe.
Let’s look into each of the steps below and then you can decide which one suits you the best as both are equally effective.
Follow the below steps to vent a washing machine drain pipe.
Step 1: Disconnect Water Supplies
Unplug the washer from the power outlet and turn off the water supplies. Make sure the washtub is empty or if there is any water left then simply arrange for a bucket to avoid flooding the floor area.
Step 2: Locate the Drain Pipe
The next step is to locate the drain pipe which will be usually attached to the back of your washer.
Step 3: Detach the Screws
There should be a screw or a cap that you can unscrew to open the pipe in the detachment process.
Step 4: Use Plunger to clear clogging
Use a plunger and try clearing the clog.
If the plunger doesn’t work, you may need to use a plumber’s snake or other types of drain clearing tool in order to clear any obstructions in the pipe.
Once the pipe is clear from obstructions, put the cap back on and pour some water down the drain to make sure it’s clear.
Turn on the washer and run a clean or empty cycle using hot water and a readymade cleaning solution or home remedies such as baking soda or white vinegar.
The second method to vent a drain pipe is by lifting the washer.
Follow the below steps to vent a washing machine drain pipe.
Step 1: Unplug the washer
Begin by unplugging your washing machine from the wall outlet and water supply.
Step 2: Tilt the Washer
Next, tilt the washer back so you can access the bottom front panel and you may need someone to help you in this course.
Once the panel is off, locate the two hoses near the bottom of the washer.
These hoses are connected to the drainage pump and need to be removed before you can continue.
Step 3: Remove the Bolts
With the hoses removed, you should now be able to see the bolts that hold the washer in place.
Use your wrench to remove these bolts and carefully lift the washer out of its housing, again you may need someone to help you with this task, as washing machines can be quite heavy.
Step 4: Remove Lint & Debris
With the washer out of its housing, you should be able to see the drain pipe more clearly.
If there is any lint or debris blocking the pipe, use your brush or vacuum cleaner to remove it.
Step 5: Reattach the Hoses & Bolts
Once the pipe is clear, place the washer in its original position and reattach the hoses and bolts.
So, if you have reached step 5, you are a pro, and many congratulations for achieving this milestone.
Things to keep in mind while venting the washer drain
When it comes to venting a washing machine drain pipe, there are a few things that you should keep in mind.
- First of all, make sure that the drain pipe is properly installed and secured. This will ensure that the pipe does not become loose and cause any damage.
- Be sure to use a proper venting system as there are a few different types of vents available, so be sure to choose one that is compatible with your washing machine.
- Always use a clean cloth or sponge to wipe down the inside of the pipe after each use. This will prevent any build-up of dirt and grime which could eventually lead to a blockage.
- Finally, never pour any harsh chemicals down the drain as this could damage the pipe in long run.
- Make sure to regularly check the vent for any blockages or damage. Not only will this help to prevent leaks and flooding, but it also helps to prevent any damage to the machine itself.
- Avoid Overuse Of Detergent.
Does the washing machine drain hose need air?
If your washing machine drain hose is constantly draining water, it may be due to a blockage in the hose.
If this is the case, you will need to vent the hose to allow the air to circulate.
There are a few ways to do this:
- Remove the drain hose from the washing machine and place it in a sink or bucket.
- Use a plunger to force air through the hose and into the washing machine.
- Detach the drain hose from the washing machine and blow into it. This will push air through the hose and into the machine.
- Run some water into the washing machine and then quickly disconnect the drain hose.
- The rushing water will push air through the hose
What is the code for washing machine drain?
Before you start plumbing the drain system make sure that you understand the code for washing machine drain pipes.
This code indicates how your washing machine will be able to ventilate the water it uses during the cycle.
When it comes to plumbing, there are standard codes that are used for just about everything.
That includes the drain pipe for your washing machine as well.
In most cases, the drain pipe for a washing machine is going to be 2 inches in diameter.
This is the standard size for most drains, so it should be easy to find a replacement pipe that fits.
As far as installation goes, the drain pipe for a washing machine should be installed so that it slopes downward at a rate of 1/4 inch per foot.
This will ensure that water can properly drain out of the pipe and into the sewer or septic system.
Additionally, the drain pipe should be installed with a P-trap so that any water that does happen to backfill, will be caught in the trap and avoid the overflow.

Frequently Asked Questions
Here are some common questions related to venting a drain pipe.
Does a washing machine drain need a P-trap?
A P-trap is a type of plumbing fixture that is typically used to prevent sewer gases and odors from entering your home through the drains. The P trap is usually installed under your kitchen sink, but it can also be used in other areas of your home, such as the bathroom. If you have a washing machine drain pipe that is not draining properly, you may need to vent it. A P-trap can help to vent the drain and keep sewer gas away.
Can you vent a drain horizontally?
If you have a horizontal drain pipe for your washing machine, then you may be wondering if you can vent this way. Nevertheless, you can vent the drain horizontally, but there are a few things to keep in mind. Foremost, the drain should be sloped so that any water will drain out and prevent any build-up in the pipe. Secondly, the pipe should be made of a material that won’t corrode or break down over time, and finally, make sure the pipe is properly sealed so that no water can escape.
How far can a vent be from a washing machine?
If your washing machine is located in an interior room, the maximum distance the vent pipe can run is around 10 to 15 feet. If the machine is located in an exterior wall, the vent pipe can be vented directly to the outside.
Will a drain work without a vent?
If you have a washing machine drain pipe that is not draining properly, you may need to vent it. A drain pipe that is not vented can cause water to backsplash out of the sink, or even worse, flood your home. You may vent a washing machine drain pipe through the roof or through the side of the house. If you have a washing machine drain pipe that is located in the basement, it is best to vent it through the side of the house. This will prevent any water damage if there is a leak in the pipe.
