Are you tired of watching clean, usable water disappear down the drain after every shower or laundry cycle? With rising utility costs and increasing environmental concerns, many homeowners in the US are looking for practical ways to reduce their water footprint without sacrificing comfort. This is where the Blue Mountain Co Plumbing 50Mm Grey Water Diverter becomes an essential component of your sustainable home infrastructure.
This device is not just a piece of pipe; it is a gateway to significant water conservation. By redirecting gently used water from sinks, showers, and washing machines to your garden or irrigation system, you can slash your municipal water usage by up to 40%. In this comprehensive guide, we will explore everything you need to know about this specific diverter, from its technical specifications to real-world application, ensuring you make an informed decision for your home.
What Is the Blue Mountain Co Plumbing 50Mm Grey Water Diverter?
Before diving into installation, it is crucial to understand exactly what this device is and why the “50mm” specification matters. The Blue Mountain Co Plumbing 50Mm Grey Water Diverter is a manual or automatic valve system designed to switch the flow of wastewater between the sanitary sewer system and a greywater reuse system.
Understanding the 50mm Specification
The term “50mm” refers to the diameter of the pipe connection, which is approximately 2 inches. This is a standard size for many residential branch lines, particularly those coming from washing machines or secondary bathroom sinks.
- Compatibility: It fits standard PVC or ABS piping commonly found in US homes built after the 1980s.
- Flow Rate: A 50mm diameter allows for a high volume of water to pass through quickly, preventing backups during heavy-use cycles like a full laundry load.
According to industry standards, proper sizing is critical to prevent pressure buildup. Using a diverter that is too small for your pipe diameter can lead to leaks or slow drainage, while one that is too large may not seal correctly. The Blue Mountain Co model is engineered to provide a tight, leak-proof seal specifically for this common residential pipe size.
Why Choose a Grey Water Diverter for Your Home?
Installing a greywater system is one of the most effective steps toward home sustainability. But why specifically choose a diverter like the one from Blue Mountain Co?
Environmental Impact and Cost Savings
Water scarcity is a growing issue across many US states, from California to Texas. By using greywater for landscape irrigation, you reduce the demand on treated drinking water supplies.
| Benefit | Description | Estimated Impact |
|---|---|---|
| Water Conservation | Reuses water for non-potable purposes. | Saves 30–50 gallons per day per person. |
| Lower Utility Bills | Reduces metered water consumption. | Can lower water bills by 20–30%. |
| Plant Health | Greywater contains nutrients like nitrogen. | Promotes healthier lawn and garden growth. |
Reliability and Build Quality
Blue Mountain Co has established a reputation for durability. Their diverters are typically constructed from high-grade, UV-resistant plastics or corrosion-resistant metals, ensuring they withstand the harsh conditions of under-sink installations or outdoor exposure. Unlike cheaper alternatives that may crack after a few seasons, this unit is designed for long-term reliability.

How Does the Blue Mountain Co Diverter Work?
The mechanism behind the Blue Mountain Co Plumbing 50Mm Grey Water Diverter is straightforward yet ingenious. It operates on a simple diversion principle.
- Normal Mode: When the diverter is set to “Sewer,” all greywater flows directly into your main sewage line, just like a standard drain.
- Divert Mode: When switched to “Greywater,” the valve blocks the path to the sewer and redirects the flow into a separate outlet pipe leading to your filtration or irrigation system.
Some models feature a three-way valve design, allowing for a “closed” position if you need to isolate the system for maintenance. This flexibility is vital for homeowners who may want to bypass the greywater system during periods of heavy rain or when using harsh cleaning chemicals that shouldn’t enter the garden soil.
Step-by-Step Installation Guide
While professional installation is always recommended for complex plumbing tasks, understanding the process helps you prepare or tackle a DIY project with confidence. Always check local codes before beginning, as regulations regarding greywater vary by state and municipality.
Tools and Materials Needed
- Blue Mountain Co Plumbing 50Mm Grey Water Diverter
- PVC primer and cement (if using PVC pipes)
- Hacksaw or pipe cutter
- Measuring tape
- Safety goggles and gloves
- Two 50mm (2-inch) slip couplings
Installation Steps
- Identify the Source Line: Locate the drain pipe from your washing machine or sink. Ensure it is a 50mm (2-inch) pipe. If it is smaller, you will need an adapter.
- Cut the Pipe: Turn off any water sources. Use your hacksaw to cut a section of the existing pipe where the diverter will be installed. Make sure the cut is straight and clean. Tip: Measure twice, cut once.
- Dry Fit the Components: Before applying glue, place the diverter and couplings into the gap to ensure everything fits snugly. The flow arrow on the diverter must point in the direction of the water flow.
- Prime and Cement: Apply PVC primer to the outside of the pipe ends and the inside of the couplings/diverter. Follow with PVC cement. Quickly insert the pipe into the fittings, giving it a slight quarter-turn to spread the cement evenly.
- Connect the Outlet: Attach the outlet side of the diverter to your greywater collection tank or irrigation distribution box. Ensure this connection is also secure and leak-proof.
- Test for Leaks: Allow the cement to cure for at least 2 hours (or as per manufacturer instructions). Run water through the system and check all joints for drips. Switch the diverter handle back and forth to ensure smooth operation.

Maintenance and Troubleshooting
Even the best plumbing fixtures require occasional care. Here is how to keep your Blue Mountain Co diverter functioning optimally.
Regular Cleaning
Greywater contains soap scum, lint, and hair. Over time, these can accumulate in the valve mechanism.
- Monthly Check: Inspect the filter screen (if equipped) and clean out any debris.
- Quarterly Flush: Run a mixture of warm water and vinegar through the system to break down soap residue.
Common Issues and Solutions
- Handle is Stiff: This usually indicates mineral buildup. Apply a silicone-based lubricant to the valve stem. Do not use petroleum-based grease, as it can degrade plastic components.
- Leaking at Joints: If you see water dripping from the connections, the PVC cement bond may have failed. You may need to cut out the section and reinstall it with fresh primer and cement.
- Slow Drainage: Check the downstream greywater pipes for blockages. The diverter itself is rarely the cause of slow drainage unless the valve is partially closed.
Frequently Asked Questions (FAQ)
1. Is the Blue Mountain Co Plumbing 50Mm Grey Water Diverter compatible with all pipe types?
It is primarily designed for PVC and ABS pipes, which are standard in US residential plumbing. If you have cast iron or copper pipes, you will need appropriate transition couplings to connect the 50mm diverter securely.
2. Can I use greywater from my kitchen sink?
Generally, it is not recommended. Kitchen greywater often contains high levels of fats, oils, grease, and food particles, which can clog irrigation systems and attract pests. Stick to water from showers, bathtubs, and washing machines.
3. Do I need a permit to install this diverter?
Regulations vary significantly by location. Many states in the US, such as Arizona and California, have streamlined permits for simple greywater systems, while others may require strict inspections. Always contact your local building department before installation.
4. How long does the Blue Mountain Co diverter last?
With proper maintenance, these diverters can last 10–15 years. The lifespan depends on the quality of the water (chemical content) and the frequency of use. UV exposure can degrade plastic over time, so if installed outdoors, consider adding a protective cover.
5. Will using greywater damage my plants?
Most household soaps are biodegradable and safe for plants. However, avoid using bleach, borax, or salts in your laundry if you are diverting that water to sensitive plants. Native plants and grasses generally thrive with greywater irrigation.
Conclusion
The Blue Mountain Co Plumbing 50Mm Grey Water Diverter is more than just a plumbing fixture; it is a smart investment in your home’s efficiency and environmental responsibility.
