The main thing you need to remember about the basement drainage system. Without proper drainage, you can face troubleshooting of basement drain blockage.

Basement drainage systems come in a variety of shapes and sizes. The basement floor drain diagram is an important part of the project, so pay attention to it. This is what’s included-

  • Inside French drain, and 
  • Exterior

Let’s take a closer look at the drains in the basement now:

Purchase the following drain tiles to set the perfect installation of basement drainage.

Drainage system

Basement drainage is almost often provided via a floor drain. It’s standard equipment in the majority of today’s new builds. The washing machine hose may be readily connected to a floor drain if you have one. 

Alternatively, you may run the hose through it. It enables the laundry to flow straight into the floor drain.

A French drain in the interior

Next, you may want to install French drains in your basement. It has a pipe with holes in it. The water is collected and transported directly into the pit using this device. 

A pump then drains the water to the surface. The pipe is protected by a layer of crushed stone or gravel. In addition, plumbers may put it just under the basement’s surface.

Drain tile on the outside

The external drain tile completes the project. You can see where the holes are by looking at the pipe. It’s a great way to get basement and groundwater garbage into the city’s sewage system.

Due to local construction standards, most houses must have an external drain tile. So, the washing machine hose may be connected to it. The water should then be pumped to the home’s main drainage and sewage system.

How Much Water You’ll Need to Lift 

The used water must be pumped away before the washing machine can be installed in the basement. Before building a pump, consider how high the water needs to be raised.

About 6 to 8 feet of lift is typical for a pump. Therefore, you must take into account the pump’s pumping capability before installing it. You don’t need a large pump for the washing machine, so don’t get one.

It’s really a matter of, “Can you empty your washing machine down the drain into your sump pump?” The drain tube for the washing machine should never be connected to the sump pump. It has the potential to pollute groundwater and provide a health risk.

The more water a washing machine uses, the larger it is in size and capacity. As a result, larger washers need more water removal. 

So, measure it out. A normal capacity for a washing machine at home is 7 kilograms (15.5 pounds). More water will need to be drained from larger washers, such as those weighing 12 kg or more.

Disposal Placement to the Washing Machine

Measure the distance between your washing machine hose and the basement drainage. This is a must if you want to utilize this method of draining the unit. 

Ideally, the distance between the hose and the draining area should be maintained properly. Otherwise, the hose will require additional pressure to reach there.

Hose lengths typically range from 5 to 10 feet with most washing machines. To make the hose reach the drain, you’ll need an extension hose.

How to Plumb a Washing Machine Drain in the Basement?

Once you’ve evaluated all of the above, you’re ready to start thinking about the drainage for your washing machine. 

When it comes to draining your washing machine, you may either connect it to a ceiling standpipe or lift it. Or add a sink tray and pump.

Method 1: Connecting the Ceiling Standpipe to the Machine

It’s possible to use the washing machine’s drain line as a standpipe if you don’t have a basement floor drain. However, if the washer has enough power to lift the drain water against gravity, you may use it. 

In addition, you must take into account how much water the washer needs to lift. You’ll need to remove the ceiling’s standpipe. 

After that, in the pipe’s cutout, screw in a Y-fitting. Finally, use strong connections to secure it. In order for the water to reach the ceilings, the washer must have adequate pressure. 

In addition, it is the most practical and least expensive drainage solution for the basement washers.


A y-fitting and two couplings are all that is needed to make this the cheapest option.

An easy-to-follow procedure from start to end is required.

When it comes to saving time, nothing beats the convenience of not having to drill through concrete.


Some washers don’t work with this: If your washer isn’t powerful enough to pump water high enough, you won’t be able to utilize this approach.

In spite of the fact that this is a simple procedure, it is essential that the drainpipe be fastened correctly.

Do not insert too deep into the standpipe. This might generate a vacuum causing water to flow back into the machine.

Method 2: Connect the Washer to the Ceiling Standpipe

Most basement ceilings are between 10 and 12 feet above the ground. As a result, the washing machine’s pump may be unable to remove the water from that altitude due to a lack of power. The washing machine will need to be raised in this scenario.

It is possible to stack some washers. In the event that your washing machine does not have this feature, you may install it on a solid, durable base. Using a wooden platform may be an option. 

To buy or make at home, it’s simple and inexpensive.

Alternatively, you may buy a washing machine pedestal and place the appliance on it to raise it off the floor. Consequently, it is a time and money saver.


The most difficult element of this installation is raising the washer up and cutting the standpipe. It is to join the new pipe fitting to the standpipe.

Build your own washing pedestal. You may expect to pay a fraction of the expense of purchasing one.

When you raise your washer, you’ll find that it’s simpler. You can reach the contents without leaning down and straining your back.


Washing machines are quite heavy. If they were to fall off their pedestals, they may injure someone.

Similarly, a weak pedestal might cause harm to the machine.

Method 3: Install Pump and Tray for a Washing Machine

It’s a simple and common practice to collect the washer’s water in a tray. Pump it to the surface once it’s been installed in the basement. 

A washing sink or tray must be installed first. The pump must be mounted underneath it. A PVC pipe is used to link a basement’s standpipe to the pump. 

In addition, make sure that the washer’s drain line is connected to the sink or tray in the bathroom.

As a consequence, placing them near one another is recommended. A washing machine hose extension will be required if you don’t have one already.


This technique of installation is simple enough that any householder may do it.

If you don’t require the help of an expert, you won’t have to pay for extra labor costs.

The sink may be used to soak extra filthy clothing or to wash your hands. It depends on your needs.


Although you save money on labor, this project may cost up to $500 or more. It is because of the sink and pumps you’ll need. 

You may not want to witness your filthy laundry water dripping into the open.

Method 4: Upgrade to a More Powerful Pumped Washer

If your washer is unable to connect to the standpipe due to a lack of electricity, it’s possible that it’s an older model that has to be replaced. 

Although it will cost a few hundred dollars to replace the washer, you may save money in the long term. 


Your new washing machine is likely to be more powerful and efficient than the previous one.

You may save money in the long run if you get newer versions that are more energy-efficient.

This implies that you won’t have to deal with the more involved methods that were previously mentioned.


Washing machines range in price from as little as $600 to as high as several thousand dollars.

Make sure you get a washing machine that is capable of pumping the drain water up. It should be high enough to reach a standpipe before attempting this solution. Similar pros and cons should be measured while setting the sink on the kitchen island.

Drainage Issues with Basement Washing Machine Installation

A few issues may arise if you want to put the washing in the basement. As a result, before you put it in the washing machine, think about these considerations.

When determining where to install your washing machine, there are a few factors to bear in mind. It might enhance the basement’s moisture, resulting in a worsening of the atmosphere.

Secondly, you’ll have issues with the washing machine’s drainage system. All of your home’s wastewater ultimately finds its way to a sewage pipe under your basement. 

As a result, a hose connecting the washing machine to the drain pipe must extend higher in the basement. It may be an issue.

The washing machine in the basement really needs to pump out the water after usage in order to reach the sewage line. If you currently have a floor drain in your basement, you could certainly connect it to it.

Most washing machines, thankfully, can pump out wasted water up to eight feet away from the machine itself. Your home’s drainage is somewhat above the basement. 

You may connect the laundry with the drainpipe using the correct hose. The measuring process is also applicable for rain shower head installation in the wall


Is it ok for there to be water in the floor drain in the basement?

No, it is not required to have 2 to 3 inches of water below the basement’s drain. Keep the drain trapping point clean by keeping the floor drain water level constant. As a bonus, it prevents sewage water from entering the drain.

Where does the wastewater from the washing machine end up?

Yes, the washing machine may be drained into the sewage system. It allows you to empty the washing machine easily. However, you need to examine your municipality’s construction requirements. It is to correct the laundry room’s drainage point.

Is it necessary to vent a drain line for a washing machine?

Yes, the washing machine’s drain line must be vented, just like the rest of the house’s plumbing. Washing machines that don’t have their drain lines vented tend to run more slowly. In addition, the stench and poisonous chemicals it emits will have a negative impact on your health.
