Selecting the Appropriate Pipe and Fittings
Choosing the right pipe and fittings is crucial to ensure a long-lasting and efficient drain system for your washing machine. Here are some considerations:
Diameter and Material:
The pipe diameter should be 1-1/2 inches in diameter to accommodate the high volume of water discharged from the washing machine. Common materials for drain pipes include:
- PVC (Polyvinyl Chloride): Durable, lightweight, and resistant to most chemicals.
- ABS (Acrylonitrile Butadiene Styrene): Similar to PVC but slightly more flexible and heat-resistant.
- CPVC (Chlorinated Polyvinyl Chloride): Used in hot water applications due to its higher temperature tolerance.
Fittings:
Essential fittings include:
- Elbows: Connect pipes at angles to change their direction.
- Tee Fittings: Create connections between multiple pipes.
- Couplings: Join straight pipe sections.
- Reducers: Transition pipes to connect different diameters.
Trap:
The trap is a U-shaped fitting installed at the base of the drain to prevent sewer gases from escaping into the house. Traps with an easily removable cleanout plug are recommended for maintenance.

| Common Drain Pipe Materials: PVC, ABS, CPVC |
| Essential Fittings: Elbows, Tee Fittings, Couplings, Reducers, Trap |
Preparing the Discharge Point
### Choose the Location
Select a suitable location for the discharge point, ensuring it’s accessible and within reach of the washing machine’s drain hose. Consider the distance, slope, and obstacles between the machine and the discharge point.
### Determine the Discharge Method
Decide the method of discharge, either directly to a drainpipe, floor drain, or outdoor drain. If connecting to a drainpipe, ensure its diameter is large enough to accommodate the drain hose. For floor drains, ensure the drain is properly sealed to prevent leaks.
### Create a Slope
Create a slight downward slope from the washing machine to the discharge point. This slope will allow water to drain freely and prevent backflow into the machine. The slope should be approximately 1/4 inch per foot.
### Secure the Drainpipe
If connected to a drainpipe, secure the washing machine’s drain hose to the drainpipe using a hose clamp or zip tie. Ensure the connection is tight and leak-proof.
Additional Tips
* Use a drain trap to prevent odors from escaping into the room.
* If installing an outdoor drain, ensure it complies with local building codes and regulations.
* Consider using a standpipe to elevate the discharge point and improve drainage.
Cutting and Assembling the Drain Pipe
To effectively connect your washing machine to the drainage system, the drain pipe must be cut and assembled accurately. Here’s a detailed guide to ensure a secure and efficient connection:
Materials you’ll need:
- Drain hose for the washing machine
- Clamps or hose clamps
- Teflon tape or plumber’s putty
- Measuring tape or ruler
- Sharp utility knife or scissors
Steps:
1. Measure and Cut the Drain Pipe: Determine the appropriate length of the drain hose by measuring the distance between the washing machine’s drain outlet and the drain pipe. Mark the measurement on the hose using a measuring tape or ruler. Carefully cut the hose at the marked point using a sharp utility knife or scissors.
2. Apply Teflon Tape or Plumber’s Putty: For a secure and watertight connection, apply Teflon tape or plumber’s putty to the threads of the drain pipe’s fitting. Wrap the tape or putty tightly and evenly around the threads to create a seal.
3. Assemble the Drain Pipe: Connect the drain hose to the drain pipe’s fitting by hand-tightening it. Ensure that the hose is fully inserted and the connection is snug. Use a wrench to further tighten the connection, but do not overtighten. Secure the connection with a clamp or hose clamp to prevent it from coming loose.
Attaching the Drain Hose to the Washing Machine
1. Locate the drain hose that came with your washing machine. It is usually a
flexible, corrugated hose that is about 6 feet long and has a diameter of 1 to 1.5
inches.
2. Slide the clamp onto the drain hose, about 6 inches from the end. The clamp
should be tight enough to hold the hose in place, but not so tight that it crimps the
hose.
3. Attach the drain hose to the drain outlet on the back of the washing machine.
The drain outlet is usually a plastic or metal pipe that is located near the bottom
of the machine.
4. Tighten the clamp to secure the drain hose to the drain outlet. Make sure that the
hose is not kinked or twisted.

Routing the Drain Pipe to the Discharge Point
Once you have chosen a suitable discharge point, you need to route the drain pipe accordingly. Here’s how to do it:
1. Measure and Cut the Drain Pipe
Determine the length of the drain pipe needed and cut it to size using a hacksaw or pipe cutter.
2. Attach the Drain Hose to the Washing Machine
Connect the drain hose to the drain pump outlet on the washing machine. Secure it with the provided hose clamp.
3. Decide on the Discharge Method
Determine if you want to discharge the wastewater directly into a drain pipe or use a standpipe.
4. Connect the Drain Pipe to the Discharge Point
If using a drain pipe, insert the drain hose into the pipe and secure it with a hose clamp. If using a standpipe, install the standpipe and connect the drain hose to it.
5. Utilize a Drainage Sump Pump
In cases where the discharge point is located below the washing machine, a drainage sump pump may be required. Install the pump and connect the drain hose to it. The pump will lift the wastewater and discharge it into the desired location.
| Discharge Method | Details |
|---|---|
| Direct Drain | Connects the drain hose directly to a drain pipe. |
| Standpipe | Installs a standpipe and connects the drain hose to it. Used when the discharge point is higher than the washing machine. |
| Drainage Sump Pump | Utilized when the discharge point is below the washing machine. The pump lifts the wastewater and discharges it. |
Testing for Leaks and Functionality
1. Water Supply Test
With the drain hose connected, turn on the water supply to the washing machine and allow it to fill with water. Check for leaks around the drain hose connection point and the water supply lines.
2. Drain Cycle Test
Place a bucket or empty container under the drain hose and start a drain cycle without any clothes in the machine. The water should drain into the container without any leaks or blockages.
3. Washing Cycle Test
Run a short washing cycle with a small load of clothes. Observe the drain hose and ensure that the water drains smoothly and does not leak. If the water backs up or drains slowly, there may be a blockage in the drain hose or plumbing system.
4. Rinse Cycle Test
After the washing cycle, start a rinse cycle and check for leaks. The rinse cycle involves draining and refilling the machine with clean water.
5. Spin Cycle Test
Start a spin cycle to test the drain hose’s ability to handle a high volume of water. Observe the hose for leaks or excessive vibration.
6. Detergent and Fabric Softener Test
Add a small amount of detergent and fabric softener to the machine and run a short cycle. Check for any leaks around the detergent dispenser or the drain hose connection point.
7. Extended Period of Use
After conducting the initial tests, monitor the washing machine for a few days to ensure that there are no hidden leaks or drainage issues. Run several different types of cycles with varying loads to test the system’s overall functionality and durability.
Installing a Drain Trap (Optional)
Installing a drain trap is essential to prevent sewer gases and odors from entering your home. It acts as a barrier, trapping water and creating a seal that keeps harmful gases out. Here’s how to do it:
1. Measure and cut the drainpipe to the desired length.
2. Insert the rubber grommet into the drain outlet of the washing machine.
3. Slide the hose clamp over the end of the drainpipe and tighten it onto the grommet.
4. Connect the other end of the drainpipe to the drain trap.
5. Tighten the hose clamp onto the drain trap to secure the connection.
6. Run a bead of sealant around the base of the drain trap to create a watertight seal.
7. Secure the drain trap to the wall or floor using screws or brackets.
8. Position the U-shaped drain trap correctly. The bottom portion of the trap should be filled with water to create a seal, so make sure the trap is not tilted or higher than the drain outlet of the washing machine. The trap must have enough slope to allow water to flow freely.
– Check for proper drainage: Turn on the washing machine and observe if the water drains smoothly through the trap. Adjust the position of the trap if necessary.
– Regularly clean the drain trap: Over time, hair, soap scum, and other debris can accumulate in the trap, blocking water flow. To prevent this, unscrew the cleanout plug located on the bottom of the trap and remove any accumulated debris.
Connecting the Drain Pipe to the Drain System
Once the drain pipe is connected to the washing machine, it needs to be connected to the drain system. This can be done by connecting the drain pipe to a drain hose or a standpipe.
To connect the drain pipe to a drain hose, the hose should be attached to the end of the drain pipe. The hose should then be routed to a nearby drain, such as a sink drain or a floor drain. The hose should be secured so that it does not come loose and leak.
To connect the drain pipe to a standpipe, the standpipe should be installed next to the washing machine. The drain pipe should then be connected to the standpipe using a rubber washer. The washer should be placed between the drain pipe and the standpipe to prevent leaks.
Once the drain pipe is connected to the drain system, the washing machine can be tested to ensure that the water is draining properly. To test the washing machine, run a cycle with no clothes in the machine. The water should drain out of the machine and into the drain system without any leaks.
Drain Pipe Connection Options
When connecting a washing machine drain pipe to a drain, you will typically have two options: a drain hose or a standpipe.
| Drain Hose | Standpipe |
|---|---|
| Connects directly to the drain pipe | Requires installation next to the washing machine |
| Easy to install | More secure connection |
| Can be used for temporary or permanent installations | Typically used for permanent installations |
