Dual flush toilet wasted more water, how to fix it

https://youtu.be/9fvWpqNGX8Q

Recently I discovered I have in fact actually wasted water for nearly three years. I learned that I need to re-adjust the Dual Flush by Danco. The URL for my original installation video is: https://youtu.be/1RDGznJm-U8

If you are like me and did not verify that in fact we are using less water, now I can show you my method so that you can double check your dual flush system and re-adjust it if necessary to save water.

This video only applies to the Dual Flush made by Danco since the Fluidmaster Duoflush has a different design, and does not have the same problem. Please check out the video for Fluidmaster system through this link: https://youtu.be/m6C1YULrPCU During the filming of the Fluidmaster video, I re-visited the Dual flush Danco design. It was a gut-wrenching experience to learn that I had wasted water every day after my installation 3 years ago of a device that was installed for the purpose of saving water. https://amzn.to/2HPUsYb

The Danco installation guide only has one diagram about adjusting the water, without a strategy to measure and compare the amount of water actually used. The instructions only say that when the Green Slide or Blue Float is down, that means less water drains. This video is very necessary to complete the installation. So please share this video with other people so that we save water.

Anyway, one lesson we learned this time is that you need to actually measure the water you flush down. You need to measure both the quick flush as well as the full flush. You may count your money carefully, but you also need to pay attention to your tank so that you are not flushing your hard-earned money down the toilet.

Alternative Methods

Toilet modification for water savings has several approaches.

1. Adjustable Flapper Valve

When to use: Fine-tuning flush volume on a standard toilet without replacing the fill valve.

Pros: Inexpensive, adjustable dial controls water per flush, universal fit for most toilets
Cons: Adjustment can be finicky, rubber degrades over time, may not seal well on older flush valves
Difficulty: Easy
Estimated cost: ~$5-10

2. Toilet Tank Bank or Fill-Cycle Diverter

When to use: Reducing water use without modifying any components.

Pros: Simply displaces water in the tank (tank bank) or diverts excess fill water (diverter), no tools needed
Cons: Minimal savings (0.5-0.8 gallons per flush), does not change flush mechanics
Difficulty: Easy
Estimated cost: ~$2-5

3. Replace with a WaterSense-Certified Toilet

When to use: When the toilet is old (3.5-7 gallons per flush) and modifications are insufficient.

Pros: Uses 1.28 gallons or less per flush, better bowl wash, may qualify for utility rebates
Cons: Full toilet replacement cost and labor, old toilet disposal
Difficulty: Medium to Hard
Estimated cost: ~$100-400 for the toilet plus installation

Always verify contractor licensing and insurance in your state. Cost estimates are averages and may vary by location.
