Many homeowners appreciate the convenience of tankless water heaters, which provide hot water on demand without the need for bulky tanks. However, these systems require regular maintenance to sustain their efficiency and longevity. One critical aspect of this maintenance is flushing the water heater, which involves using a pump to circulate a cleaning solution through the system. This process helps remove mineral build-up, ensuring optimal performance.
A suitable pump is essential for effectively flushing a tankless water heater. The right pump will depend on various factors, including the heater’s capacity, the flow rate required, and the specific cleaning solution used. Selecting a pump that is too small can result in ineffective cleaning, while an oversized pump may lead to unnecessary energy consumption.
In this article, we will review an excellent option for flushing tankless water heaters, discussing its features, performance, and suitability for different buyers. Our focus will be on helping you understand what size pump is appropriate for your needs.
Here’s a quick comparison of the pump options we’ll be discussing:

Understanding Pump Size for Tankless Water Heaters
Choosing the correct pump size for your tankless water heater is vital for optimal performance. A pump that is too small may struggle to provide the necessary flow rate, leading to incomplete flushing. Conversely, an oversized pump can waste energy and may not perform as expected with the heater’s design.
Typically, a pump with a flow rate of around 1000 GPH is suitable for most tankless water heaters. This rate ensures that water circulates effectively, allowing for thorough cleaning of the unit. Additionally, consider the height the pump needs to lift water, as this can affect the pump’s efficiency and required size.
Types of Pumps for Flushing Tankless Water Heaters
When it comes to flushing tankless water heaters, two primary types of pumps are commonly used: submersible pumps and inline pumps. Each type has its advantages and disadvantages.
Submersible pumps, like the one included in the 6699 kit, are designed to operate underwater. They are typically quieter and more efficient for tasks like flushing water heaters. Inline pumps, on the other hand, are installed in the plumbing system and are better suited for continuous operation but may require more complex installation.
For most homeowners, a submersible pump is the preferred choice for flushing due to its ease of use and portability. They can be quickly set up and removed, making maintenance straightforward.
Calculating the Right Flow Rate for Your System
Determining the appropriate flow rate for your tankless water heater is crucial. It’s typically calculated based on the heater’s specifications and your household’s hot water demands. A rule of thumb is to look for a pump that can deliver at least as much flow rate as the heater’s maximum output.
For example, if your tankless water heater has a maximum flow rate of 3 GPM (gallons per minute), you’ll need a pump that can deliver at least 180 GPH for effective flushing. Always consult your heater’s manual for specific recommendations.
Step-by-Step Guide to Flushing Your Tankless Water Heater
Flushing your tankless water heater is a straightforward process that can greatly enhance its efficiency. Here’s a simple step-by-step guide:
- Gather your flushing kit components and the cleaning solution.
- Turn off the power supply to the water heater.
- Connect the pump to the heater’s isolation valves using the included hoses.
- Fill the bucket with a mixture of water and the cleaning solution.
- Submerge the pump in the bucket and turn it on.
- Allow the solution to circulate for 30 minutes to an hour.
- Flush with clean water to remove any remaining solution.
Follow these steps annually for optimal performance.
Maintenance Tips for Your Pump and Water Heater
Regular maintenance of both your tankless water heater and the flushing pump is essential. For the heater, ensure you flush it at least once a year to prevent mineral build-up. This can prolong the life of the unit and maintain its efficiency.
For the pump, regularly check for any wear or damage, particularly around the power cord and hoses. After each use, clean the pump thoroughly and store it in a dry place to prevent rust and corrosion.
Common Mistakes and Troubleshooting
Flushing a tankless water heater is generally straightforward, but there are common mistakes to avoid. One frequent error is using an inadequate flow rate pump, which can result in incomplete flushing. Always double-check the specifications before purchasing.
Another issue can arise from improperly connecting the hoses, leading to leaks or inefficient circulation. Make sure connections are snug and secure to prevent any issues during the flushing process.
Environmental Considerations and Best Practices
When flushing your tankless water heater, consider the environmental impact of your cleaning solution. Using biodegradable cleaners can reduce your ecological footprint. Additionally, ensure that any waste water is disposed of properly and does not contaminate local water sources.
Best practices also include reusing the flushing solution if it’s still effective, as this can minimize waste and save on cleaning costs.
Final Recommendations
The 6699 Tankless Water Heater Flushing Kit stands out as an excellent choice for homeowners looking to maintain their tankless systems. Its ease of use, effective performance, and complete kit make it ideal for DIY enthusiasts. For those considering a pump purchase, ensure you evaluate your specific needs carefully, paying attention to flow rates and compatibility with your heater.
