What is a Washing Machine Stand Pipe?
A washing machine standpipe is a pipe that is used to connect a washer to a drainage system.
The standpipes are usually made of PVC or other durable material and are available in a variety of sizes.
The most common size is 2 inches in diameter, but standpipes can also be 3 or 4 inches in diameter.
One end is connected to the washing machine, and the other end connects to the drainage.
The standpipe ensures effective draining of your washer and keeps it from vibrating.
It also keeps sewer gas from entering your home which can be harmful to your health.
What are the different types of washer standpipes?
There are two different types of washing machine standpipes, vented and non-vented.
Vented standpipes have a small hole in the top of the pipe that allows air to enter the pipe as water is draining out.
It prevents vacuum formation and prevents water from coming back into the machine.
Non-vented standpipes do not have this hole, so a vacuum can form and water may siphon water back into the machine.
How to Install a washing machine standpipe?
If you are planning to install a washing machine, then you need to ensure proper plumbing for your washer.
That means having suitable standpipe plumbing for the drainage hose.
Here’s a step-by-step Instruction to install a standpipe in the washing machine.
Step 1: Measure the Height of your washing machine
First, you’ll need to measure the height of your washing machine.
The standpipe needs to be at least 6 inches taller than the highest point of the machine.
Next, measure the diameter of the drainage hose.
Ensure that the standpipe is big enough to accommodate the hose.
Step 2: Find a location for the standpipe
The standpipe should be close to the washing machine and it should lead outside the house or to a floor drain.
Once you’ve found a suitable location, mark the spot from where the standpipe will go
Step 3: Install the Standpipe
Start by drilling a hole in the floor where you marked earlier.
If your standpipe needs to go through an exterior wall, then make sure to drill a hole that fits the drainage hose.
Thread the standpipe through the hole and secure it in place with plumbing nuts.
There are grooves inside the pipe to provide a tight fit around them in case of an adjustable standpipe.
Next, drill holes for the anchors in the wall and dry-fit them in place to make sure that it fits correctly.
Once you’re satisfied, attach the anchors and route the pipeline.
Note: Use clamps or cable ties if necessary. It is recommended that you leave a 1/2-inch gap between the standpipe and the wall.
Voila! the installation is been successfully completed.
Now you will need to pour some water through the washer to check for any leaks.
These tasks usually require professional plumbers or if you are well versed with them.
How to choose a suitable standpipe for my washer?

The most common types of standpipes are made from PVC or metal.
Some are made from other materials such as wood or concrete.

It becomes important to choose the one that suits your requirements.

Before purchasing a standpipe, get your measurements calculated.

Don’t wait any longer to buy a new standpipe if needed.
The lifespan of standpipes ranges around 10 years and up to 20 years or longer.
Considering the facts will ward off any problems that might arise later.
Make sure to choose a dirt-resistant, durable, and sturdy standpipe.
Doing this will prevent any leaks and water contamination in the long run.

A standpipe is a vertical pipe that drains water from your washing machine to the sewer.
It is of utmost importance to keep your standpipe clean to prevent clogs and other issues.
Clean your standpipe every month or so, depending on how often you use your washing machine.
