Top 5 Ways to Protect Irrigation Systems with Pump Houses and Outdoor Water Supplies Over Winter

A comprehensive guide for pump-house-based systems

As winter approaches, protecting your irrigation system becomes a top priority, especially when it involves pump houses and outdoor water supplies. Standard winterizing may not always be enough, particularly for systems with centrifugal pumps and backflows located in mail kiosks, sheds, or other outbuildings. These components need special attention to prevent costly damage during freezing temperatures.

Here are some key steps to ensure your irrigation system is well-protected:

1. Keep pump houses and equipment rooms heated

Many pump houses or outbuildings were designed to remain heated through the coldest months. It's essential to ensure that heaters in these areas are fully operational. Regularly check that the heating system is working throughout the winter. Proper insulation and door sweeps can help keep cold drafts out and ensure the room stays warm enough to protect your equipment.

2. Ensure heat circulates freely

Clutter in pump houses or equipment rooms can prevent heat from circulating properly, leaving parts of the room susceptible to freezing. Keep the space clear to allow even heating.

3. Check shutoff valves

It’s crucial to locate below-ground shutoff valves and ensure they are in good working condition. Closing these valves prevents live water from entering the system during the winter. If your system lacks this option, it becomes even more vital to maintain the room’s heat to avoid frozen or cracked valves, which can allow water to flow back into the irrigation system.

4. Consider disassembling components

As an extra precaution, you can disassemble the plumbing inside the room, including pumps and backflows. This prevents water from entering these sensitive components if any water happens to bypass the shutoff valve.

5. Understand ownership responsibility

Remember, the responsibility for maintaining plumbing components upstream from the irrigation shutoff valve typically falls on the property owner, not the irrigation contractor. Ensure that your property’s infrastructure is prepared for the winter to avoid unexpected damage.

By following these steps, you can avoid the common winter issues that lead to frozen pipes, damaged pumps, and costly repairs. Protect your irrigation system now to ensure smooth operation come spring.
