The Navien 20021730BA 5-pack Backup Rings are replacement components for Navien condensing tankless water heaters. These rings are designed to prevent water leakage and ensure the proper sealing of the heater. Here are some pros and cons of buying these backup rings:

1. OEM (Original Equipment Manufacturer) Compatibility: These backup rings are manufactured by Navien, the same company that makes the water heaters they are intended for. This ensures a perfect fit and compatibility with the heater.

2. Leak Prevention: The primary function of these backup rings is to prevent water leakage, which is essential for maintaining the efficiency and longevity of the water heater.

3. Easy Installation: The backup rings are designed for easy installation, which can save time and effort, especially for DIY homeowners.

4. Affordable Replacement: The cost of these backup rings is relatively affordable compared to the cost of replacing the entire water heater, making them a cost-effective solution for heater maintenance.

1. Limited Use: These backup rings are only intended for use with Navien water heaters, so they may not be a viable option for those with different brands or models.

2. Short Lifespan: Depending on the water quality and usage patterns, these backup rings may need to be replaced more frequently than expected.

3. Single Packaging: The backup rings come in individual packages, which may result in additional shipping costs for bulk purchases.

In conclusion, the Navien 20021730BA 5-pack Backup Rings offer several benefits, including OEM compatibility, leak prevention, easy installation, and affordability. However, they also have some drawbacks, such as limited compatibility, potential for a short lifespan, and individual packaging.

If you own a Navien water heater and are experiencing leaks or other issues related to the sealing of the heater, these backup rings can be a cost-effective solution. However, if you're not certain of your water heater's brand or model, it's recommended to consult with a professional plumber or the heater's manufacturer to ensure you're purchasing the correct replacement parts.
