How to Reuse Detergent Water When Washing Clothes in a Washing Machine

Saving money and being eco-friendly can be easier than you think. One way to do this is by reusing water from household appliances like your washing machine. This type of used water is known as “gray water” because it contains dirt and soap, making it unsafe for drinking but perfect for other uses. It’s different from “black water,” which comes from toilets and can’t be reused. To reuse gray water from your washing machine, you’ll need to disconnect it from the sewer system and set up a new drainage system to collect and use the water elsewhere.

Disconnect the Washing Machine – How to?

Step 1: Find the Discharge Hose

First, look for the discharge hose at the back of your washing machine. It connects to a utility box in the wall, which also has two water valve connections. You’ll probably need to pull your washing machine away from the wall to see and reach the hose clearly.

Step 2: Unplug the Washing Machine

Before you start handling the hose, make sure to unplug your washing machine. This is important because there might be some water spills, and you don’t want to risk getting an electric shock. Just find the power outlet and unplug the machine.

Step 3: Turn Off the Water Supply

Next, turn off the water supply to your washing machine. This stops water from running into the machine while you’re working. Locate the two valves in the utility box and turn them to the off position.

Step 4: Disconnect the Discharge Hose

Now, it’s time to disconnect the discharge hose. This is the biggest tube at the back of the machine, usually leading into the wall to the sewage system. Pull the hose up and out; it should come loose without much effort. Be prepared for some water to spill, so put some towels on the floor behind the machine and have a bucket ready. Let the hose drain fully into the bucket before you disconnect it completely.

Step 5: Attach an Extension to the Hose

Finally, you’ll need to attach an extension to the drainage hose. You can find extension kits at hardware stores. These kits include a length of hose and a coupler, which is a small piece of plastic with two holes to join the hoses. Use the clamps in the kit to secure the coupler by tightening them around the hoses with pliers.

How to Set Up a New Drainage Solution?

Step 1: Position a Large Container

Start by finding a large plastic container and placing it close to your washing machine. Make sure it’s big enough to hold a lot of water since washing machines use a hefty amount. Newer models use around 14 to 25 gallons per load, while older ones can use up to 45 gallons. To be on the safe side, pick a container that can hold at least 50 gallons. If you can, set it up in your yard right outside the laundry room and elevate it with cinder blocks or bricks to help with drainage.

Step 2: Redirect the Discharge Hose

Next, you’ll need to run the washing machine’s discharge hose into the container. Just place the hose into the top of the container so the water from your machine will flow into it after each wash. To prevent splashing, you can cut a hole in the container’s lid just big enough for the hose to fit through.

Step 3: Attach a Garden Hose to the Bottom

Now, you’ll want to install a garden hose at the bottom of the container. Drill a one-inch hole and insert a male pipe thread to garden hose thread adapter. This lets you connect the garden hose to your container. Make sure the garden hose thread part is sticking out of the container. Use silicone around the adapter to seal it and prevent any leaks.

Step 4: Direct the Garden Hose to Your Plants

Finally, lay the other end of the garden hose near a plant in your yard. This setup allows the water to flow from your washing machine, through the hose, and into the ground, helping to water your plants. If you don’t have any plants that need water, you can add some wood mulch to your yard. The gray water will flow through the mulch and into the ground without waterlogging your yard.

Making the Most of Gray Water

Step 1: Use Plant-Friendly Detergents

When using gray water, make sure to avoid detergents with bleach, boron, or salt as these can harm plants and may be toxic to animals and people. Check your detergent’s ingredients if you plan on reusing the water from your washing machine.

Step 2: Move the Hose Regularly

To avoid waterlogging one spot in your yard, move the garden hose around frequently. Ideally, you should change its position with each load. If you have several plants that need watering, move the hose to each one in between loads. Otherwise, let the water drain into different parts of your lawn.

Step 3: Take Apart the System in Winter

If you live in an area where the ground freezes during winter, dismantle your gray water system for the season. Plants don’t need watering during this time, and dealing with gray water becomes trickier. If your container is kept outside, disconnect your washing machine from it and put the drainage hose back into the sewage disposal hole at the back of the washing machine.

Warnings!

Know the Local Regulations:

Before you start reusing gray water, make sure to check your local laws and regulations. In some areas, there might be specific rules or even restrictions about using gray water. It's important to stay informed and compliant to avoid any legal issues.

Manage Gray Water Properly:

Improper management of gray water systems can cause a range of problems. If not handled correctly, gray water can produce unpleasant odors, attract pests, and even harbor harmful pathogens. These issues can pose serious health risks to you and your family. Make sure to maintain your system regularly and follow best practices to keep everything safe and hygienic.

Here’s How to Save Detergent:

Use the Right Amount:

Many people use more detergent than necessary. Always follow the manufacturer’s guidelines for the correct amount of detergent for your load size and soil level. Overusing detergent not only wastes money but can also leave residue on your clothes and washing machine.

Opt for Concentrated Detergents:

Concentrated detergents require less product per load. They are often more cost-effective and have a smaller environmental footprint due to reduced packaging and transportation needs.

Choose High-Efficiency (HE) Detergents:

If you have a high-efficiency washing machine, make sure to use HE detergents. These detergents are formulated to work with less water, ensuring effective cleaning without excess suds.

Pre-Treat Stains:

Treat stains before washing to avoid using extra detergent. Use a small amount of detergent directly on the stain or a specialized stain remover to tackle tough spots.

Wash Full Loads:

Running full loads optimizes water and detergent usage. However, avoid overloading the machine as it can impact cleaning efficiency and cause wear and tear.

Use Cold Water:

Washing clothes in cold water can save energy and is often effective for cleaning. Modern detergents are formulated to work well in cold water, reducing the need for hot water and additional detergent.

Final Words!

Going for these tips can significantly save detergent costs, reduce water waste, and contribute to a more sustainable household routine. By being mindful of detergent use and exploring ways to reuse detergent water, you can make a positive impact on both your wallet and the environment.
