EcoFlush B8106 Pressure Assisted Toilet Flush System Instruction Manual

1. Introduction

The EcoFlush B8106 is a pressure-assisted flush system designed to enhance toilet performance and promote water conservation. This patented technology utilizes supply line water pressure, storing it within an engineered pressure vessel. Upon activation of the flush handle, a high-pressure water flow is discharged into the toilet bowl, facilitating an ultra-efficient and powerful flush. This system is engineered to reduce water usage, contributing to environmental sustainability.

This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of your EcoFlush B8106 unit.

3. Setup and Installation

The EcoFlush B8106 is designed for straightforward drop-in replacement. Ensure all necessary hardware is present before beginning installation.

Installation Steps:

1. Preparation: Turn off the water supply to the toilet and flush to empty the tank. Remove the old flush system.
2. Handle Control Unit: It is recommended to install the handle control unit while the main EcoFlush unit is still loose in the tank. Align the main unit with the tank opening, engaging a thread or two, then install and secure the handle control unit. This can prevent difficulties encountered if the main unit is fully tightened first.
3. Positioning the Unit: Carefully lower the EcoFlush B8106 unit into the toilet tank. Ensure it is properly seated and aligned with the tank opening.
4. Securing the Unit: Tighten the tank mount bolts with a wrench. Apply firm but gentle pressure to prevent overtightening, which could damage the porcelain.
5. Water Intake Port: Securely tighten the water intake port with a wrench. This is crucial for preventing leaks, especially given the pressurized nature of the system. Ensure the gasket is properly seated and compressed.
6. Connecting Lines: Attach the two lines from the flush system to their respective connections. The unit typically comes with components zip-tied for convenience, ensuring all parts are in alignment.
7. Water Supply: Once all connections are secure, slowly turn the water supply back on and check for any leaks.

Special Considerations for Gerber Toilets:

For Gerber toilet installations, there may be limited space between the bladder and the tank wall for the flush handle installation. It might be necessary to carefully shave a few threads off the handle spud to ensure a proper fit. Use a sharp knife for this modification to avoid damaging the plastic handle spud.

4. Operating Instructions

The EcoFlush B8106 system features a "Feathertouch flushing activation" for ease of use and a "Powerful Flushing System" for effective waste removal.

Flushing the Toilet:

• Gently press or push the flush handle downwards. The system is designed for a light touch.
• The pressure-assisted mechanism will activate, releasing 1.6 gallons (6 Lpf) of water into the bowl for a complete and efficient flush.
• Allow the tank to refill completely before attempting another flush.

5. Maintenance

The EcoFlush B8106 is designed for durability and minimal maintenance. Regular cleaning of the toilet bowl and exterior is recommended to maintain hygiene and appearance.

General Care:

• Avoid using harsh chemical cleaners or in-tank drop-in tablets, as these can damage the internal components of the flush system and may void the warranty.
• For cleaning the toilet bowl, use standard toilet bowl cleaners and a brush.
• Periodically inspect the connections for any signs of wear or leaks.

6. Troubleshooting

This section addresses common issues that may arise with your EcoFlush B8106 system.

Common Issues and Solutions:

• Leaking from Tank Seal:

  If water is leaking from the tank seal, ensure the tank mount bolts are sufficiently tightened. While avoiding overtightening that could damage porcelain, they should be more than finger-tight. Also, verify that the water intake port is firmly wrenched to ensure the gasket is properly sealed.
• Handle Not Fitting (Gerber Toilets):

  As noted in the installation section, some Gerber toilets may have clearance issues for the handle spud. If the handle does not fit, carefully trim a few threads from the plastic handle spud using a sharp knife to allow for proper installation.

• Loud Flushing Noise:

  Pressure-assisted flush systems are inherently more powerful and can produce a louder flushing sound compared to gravity-fed toilets. This is generally a characteristic of the system and not an indication of a malfunction.

• Reduced Flush Performance:

  Ensure the water supply valve is fully open. Check for any obstructions in the toilet bowl or trapway. If the issue persists, inspect the internal components for any visible damage or blockages. Turn off the water supply and flush the unit before servicing.
