How Do I Switch Between Filtered and Unfiltered Water?

Learn to use your diverter valve to maximize filter life and get the right water for every task.

Understanding Your Diverter Valve

Your Crystal Quest countertop filtration system connects to your existing faucet through a diverter valve. This clever component allows you to direct water flow either through your filtration system or straight from your tap, giving you complete control over when and how you use filtered water.

The diverter valve serves as the gateway between your faucet and your filtration unit. When properly installed, it creates a seamless connection that makes switching between water sources effortless.

How the Diverter Valve Works

Inside your diverter valve, a simple mechanism redirects water flow based on the position of the switch or lever. Here is what happens with each setting:

Unfiltered Position: Water flows directly from your faucet as normal, bypassing the filtration system entirely.
Filtered Position: Water is redirected through the tubing into your Crystal Quest unit, passes through the filter media, and exits through the filtered water spout.

Using the Diverter Valve Lever

Operating your diverter valve is straightforward once you understand the positions. Crystal Quest diverter valves feature a rotating switch styled lever, for simple on/off use.

Rotating-Style Diverter Valves

Turn on your faucet to begin water flow.
Rotate the switch to the filtered position, the level is typically rotated from a vertical position to a horizontal position.
Allow filtered water to flow from your unit.
Rotate back to the unfiltered position when you no longer need filtered water.

Tip: Turn off the faucet before switching diverter positions to prevent water hammer and reduce stress on the valve components.

When to Use Filtered Water

Filtered water from your Crystal Quest system is ideal for consumption and applications where water quality directly affects taste or health. Use filtered water for:

Drinking: Enjoy clean, great-tasting water free from contaminants.
Cooking: Enhance the flavor of soups, pasta, rice, and other dishes.
Beverages: Make better coffee, tea, and other drinks.
Baby formula: Ensure the purest water for infant nutrition.
Pet water bowls: Give your furry friends the same quality water you enjoy.
Filling water bottles: Take clean water with you on the go.
Watering sensitive plants: Some houseplants prefer filtered water without chlorine.

When to Use Unfiltered Water

Not every task requires filtered water. Switching to unfiltered mode for certain activities helps preserve your filter life without sacrificing results. Use unfiltered water for:

Washing dishes: Regular tap water works perfectly for cleaning.
Rinsing produce: A quick rinse before final filtered water wash is sufficient.
Cleaning tasks: Mopping, wiping counters, and general cleaning.
Watering most plants: Most outdoor and indoor plants tolerate tap water well.
Hand washing: Regular tap water is appropriate for washing hands.

Preserving Filter Life Through Smart Switching

Your Crystal Quest filter has a specific capacity measured in gallons. Every gallon that passes through the system uses a portion of that capacity. By switching to unfiltered water for non-critical tasks, you can significantly extend the time between filter replacements.

Best Practices for Maximizing Filter Longevity

Default to unfiltered: Keep your diverter in the unfiltered position as the standard setting. Switch to filtered only when you need it.
Be mindful of volume: Filling a large pot for pasta uses several quarts. Consider whether filtered water is necessary for the task.
Track your usage: Keep a mental note of how much filtered water you use daily to better estimate filter replacement timing.
Switch promptly: Once you have collected the filtered water you need, switch back to unfiltered right away.

The Impact of Smart Switching

Consider this example: A household that runs all water through their filter might use 10 gallons per day. By switching to unfiltered for dishes, cleaning, and other tasks, they might reduce filtered water usage to just 2-3 gallons daily. This simple habit can extend filter life by three to five times, saving money and reducing maintenance frequency.

Troubleshooting Common Diverter Issues

If you experience any difficulties with your diverter valve, here are some quick solutions:

Stiff lever or switch: A small amount of food-grade silicone lubricant can help. Avoid petroleum-based products.
Water leaking at the diverter: Check that all connections are hand-tight. Replace worn washers or O-ringsif necessary.
Low flow to the filter: Ensure the diverter is fully engaged in the filtered position. Check for sediment buildup at the aerator.
Diverter not staying in position: The internal mechanism may be worn. Contact Crystal Quest support for a replacement diverter.

Making It a Habit

Switching between filtered and unfiltered water quickly becomes second nature. Within a few days of using your Crystal Quest system, you will instinctively reach for the diverter when you need clean drinking water and leave it in bypass mode for everyday tasks. This simple practice ensures you always have high-quality filtered water when it matters most while getting the maximum value from every filter cartridge.
