As the temperatures drop, it’s important to take the proper steps to protect your DAB Mini 3 from freezing damage. Winterizing your system ensures it will be ready to perform efficiently when warm weather returns—and saves you from costly repairs or replacements.
Here’s how to properly winterize your DAB Mini 3, following Summit Water’s recommended best practices.
Step 1: Shut Down and Prepare the System
Before draining, take the following preparatory steps:
- Shut down the well or storage tank.
- Unplug your DAB Mini 3 from the power source.
- Turn off the inlet supply valve if your DAB Mini 3 is used in a pressure boost application.
These actions ensure safety and prevent any water from entering the pump during the winterization process.
Step 2: Drain the Pump System
Begin by removing the plugs from any unused ports on your DAB Mini 3. This allows residual water inside the system to drain out completely. Disconnect the unit from the outlet (discharge) side to ensure all water exits the system.
Next, remove the priming plug on the top of the pump. This step is crucial—it allows air to enter the system and replace the draining water, preventing any trapped moisture from freezing inside the pump housing.
Step 3: Adjust for Your Plumbing Setup
Depending on how your DAB Mini 3 is installed, you’ll need to remove different plugs to allow for complete drainage:
- If your Esybox is plumbed from the front: Remove the plugs from the alternate plumbing connection on the base to let water drain out.
- If your Esybox is plumbed from the base: Remove the plugs from the front.
This ensures that water doesn’t remain trapped in any portion of the system, reducing the risk of freeze damage.
Step 4: Drain the Discharge Side
Don’t forget to drain the plumbing that leads from the pump to your house (the discharge side). Disconnect this line and make sure all water is cleared out. Any leftover water here can freeze and cause cracking or damage to fittings and pipes.
Step 5: Avoid Anti-Freeze Products
It can be tempting to add plumbing anti-freeze for extra protection, but it’s best to avoid using any glycol-based products with the DAB Mini 3.
Step 6: Store in a Warm Location (If Possible)
If your setup allows, the best option is to remove the pump completely and store it in a warm, dry location over the winter. While this may not be practical for every installation, it’s the most effective way to ensure your DAB Mini 3 remains in top condition through the cold months.
Final Tips from Summit Water
A few minutes spent winterizing your DAB Mini 3 can save hours of maintenance and hundreds of dollars in repairs come spring. Always double-check that every plug has been removed and that the system is fully drained before temperatures drop below freezing.
