You can divert washing machine water by installing a diverter valve on the drainpipe, allowing you to redirect specific cycles, like the final rinse, to a water butt or other storage container.
Here's a more detailed explanation:
Steps to Divert Washing Machine Water:
-
Identify the Washing Machine Drainpipe: Locate the pipe where the washing machine discharges used water. This is usually connected to a sink drain or a dedicated drainpipe.
-
Install a Diverter Valve:
- A diverter valve is a fitting that allows you to choose between two output paths for the water. You can buy these at most hardware stores.
- Cut the drainpipe at a suitable location and install the diverter valve according to the manufacturer's instructions. This might involve using couplings and pipe cement, depending on the type of pipe used (e.g., PVC).
- Ensure all connections are secure and watertight to prevent leaks.
-
Connect to a Water Butt or Storage Container:
- Attach a hose to one outlet of the diverter valve and run it to your water butt or chosen storage container.
- Ensure the hose is securely fastened to both the valve and the container to prevent detachment during water discharge.
-
Divert the Water During Appropriate Cycles:
- During a washing machine cycle, manually switch the diverter valve to direct the water to the storage container during cycles where the water is relatively clean (e.g., the final rinse cycle, especially if using eco-friendly detergents).
- For cycles with harsh chemicals or dirt, keep the valve set to the regular drain. This avoids contaminating your stored water.
Important Considerations:
- Water Quality: Washing machine water (even from the final rinse) is greywater and not potable. It's suitable for watering plants (except edible ones, generally), cleaning outdoor areas, or flushing toilets (where local regulations allow).
- Detergent Type: Using eco-friendly, biodegradable detergents minimizes the risk of harming plants when reusing the water.
- Regulations: Check local regulations regarding greywater reuse, as some areas have specific restrictions.
- Plumbing Skills: If you're not comfortable with basic plumbing, it's best to hire a qualified plumber to install the diverter valve. Incorrect installation can lead to leaks and water damage.
- Siphoning: If the water butt is lower than the washing machine drain, gravity will assist the process. If not, you might need a pump or siphon to facilitate water transfer.
- Filtration: For some applications, you might want to consider a simple filter to remove lint or debris from the diverted water.
Advantages of Diverting Washing Machine Water:
- Water Conservation: Reduces your reliance on municipal water supplies.
- Cost Savings: Lowers your water bill.
- Environmentally Friendly: Reduces the demand for treated water and minimizes the strain on water resources.
By carefully planning and implementing a washing machine water diversion system, you can conserve water and reduce your environmental impact. Remember to prioritize safety and follow local regulations regarding greywater reuse.
