Washing Machine Drainage Options

It’s no secret that washing machines consume a lot of water and that dirty water must be disposed of. The scenario you’re in with your plumbing makes a difference.

Can I Let My Washing Machine Drain Outside?

Use a biodegradable laundry detergent to clean the inside. It’s nice to have a grey water tank or pump, but it’s not required.

You might wonder if this is safe for your lawn and plants. Much of it depends on the detergent you’re using and the type of washing machine you use.

If it’s a laundry washing machine, you’re probably safe, but a dishwashing machine, then it’s not very good to drain outside for your plants and into your garden soil.

Laundry water is classified as “greywater,” which means it will cause minimal damage to your lawn and hasn’t come into contact with water from toilets.

You shouldn’t have any problems using laundry water for irrigation if you use environmentally friendly, biodegradable detergents. Dish detergent is too caustic for most plant life.

There are a few things to consider if you want to use greywater in your yard:

Phosphorous-based detergents are beneficial to plants, but sodium-based detergents are not. Therefore, detergents with low sodium and mild phosphorus are suitable.

Do not use excrement to water your yard if you regularly wash diapers or other goods with feces. The germs in this water can get you sick. It’s a significant health hazard. It’s the equivalent of attempting to water your plants with your septic tank.


Is it legal?

The legality of greywater use also falls under a gray area and depends on the laws of your neighborhood. Before you install piping, check with the local HOA and land regulations.

How To Drain Washing Machine Outside

Because each washing machine tub plumbing system differs, you may need to follow specific rules; the steps are basic and need adjusting to fit your home and neighborhood.


The first step is to determine where you’d like to empty the washing machine.

You can drain into a barrel (so you can irrigate your grass in smaller bursts), your irrigation system, or simply a hose outside, thus minimally damaging areas you water.

If you use a barrel, make sure it holds at least 41 gallons of water because this is the average water load for a washer.

If you wish to drain laundry water from a basement to the ground floor, you’ll need a laundry sump pump and possibly a licensed plumber to do this installation for you.

Whatever your strategy, you’ll need a 1-inch hose to channel the water through, along with additional tubing.

Connection Options for Washing Machine Drain Hose

A washing machine drain hose can be connected to your home plumbing in two ways. A washing machine drain is usually suspended over a slop sink or linked to a separate vertical drain pipe.

Slop Sink Connection

Using a slop sink (utility sink) is simple yet no longer recommended. The drain line is immediately linked to a washbasin, and the hose hung from the side over the sink’s rim. You need a large air space between the drain pipe and the sink’s bottom as this air gap prevents backwater from entering your washer.

Unfortunately, the sink drain pipe may not handle the water drained from the washing machine and could lead to flooding.

Washing Machine Drain Hose Maintenance

While the hose connection may appear to be a one-time activity, this does not negate the significance of maintaining the hose clean and secure.

You can add a filter to the end of the hose drain once it’s installed and attached. You can make your filter out of an old sock or pantyhose or buy a ready-made aluminum or nylon filter.

Lint and grime from your clothes prevent entering the drainpipe, gathering on the inside surface, and producing a blockage.

Whether you use a handmade or commercial filter, make sure you remove it regularly.

Depending on how often you use the washing machine, don’t wait more than 60 days to clean it and replace it if necessary. The majority of the lint and dirt will collect on the filter, which you may clean with a garden hose.

There may also be a significant amount of debris at the bottom of the washer. To ensure proper draining from the washing machine, it must be thoroughly cleaned. Clogging and overflow can be caused by debris, whether on the drainpipe or the hose.

Rubber drain hoses are a more cost-effective option. It’s been around for decades, and newer versions have braided polyester mesh or rayon for added robustness.

If you wish to go with a rubber drain hose, look for one that says “reinforced” with either of the materials listed for added durability.
