Summer Reliability Checklist: Keep Your Plunge Running Strong in the Heat – Plunge Support

As summer temperatures rise, your Plunge works harder to keep things cool. A little extra care goes a long way—this checklist will help you keep your Plunge clean, efficient, and reliable all summer long.

✅ 1. Give Your Plunge Room to Breathe

Proper airflow and ventilation are critical for chiller performance—especially during hot weather. Now is the time to check your spacing and placement.

Select your model for specific requirements:

🚫 2. Protect Your Plunge from Sprinklers and Garden Hoses

The Plunge is built to handle vertical water (like rain), but horizontal water (like sprinklers or garden hoses) can damage the chiller and internal components.

Avoid direct spray from:

Sprinklers
Garden hoses
Pressure washers

💧 3. Ensure Proper Water Flow and Cleanliness

Proper water flow is essential for system health and cooling efficiency. Dirty or low-flow water forces the chiller and pump to work harder—especially in the heat.

Follow these best practices:

Follow your Water Maintenance Manual
Skim leaves or debris daily
Clean tub drains every other day
Replace the filter at least once per month (more often in dusty/pollen-rich areas)
Deep clean the Plunge every 6–9 months

⚡ 4. Ensure Proper Electrical Setup

Using an Extension Cord?

Must be 12 gauge, no longer than 10 feet
Follow all safety guidance in your Plunge manual
Refer to NEC requirements for your jurisdiction

Outdoor Plunge Setup

Use outdoor-rated power cords and outlets
Use a weatherproof outlet cover that fully encloses the GFCI plug
Use a Weatherproof Connection Box for extension cord connections

🌤️ 5. Shade Your Plunge if Possible

All Plunge models are outdoor-rated, but direct sun exposure makes the chiller work harder, increasing wear and power usage.

Pro Tips:

Place the tub in a shaded area
Use a canopy, umbrella, or cover when not in use
For commercial Plunges with auto-dosers, the auto-doser must stay shaded

📲 6. Check for Firmware Updates (Evolve Pro & All-In Only)

Make sure your Plunge is running the latest firmware. Updates improve:

System performance
Efficiency
New feature support

Use the app to check for updates and install the latest firmware.

💦 7. Understanding Condensation (vs. Leaks)

Seeing moisture on your Plunge or a small puddle nearby? In summer, this is likely normal condensation, not a leak.

To confirm:

Place tape on the current water line inside the tub
Wait 24 hours (no use or added water)
Recheck the water level

If the level hasn’t dropped, it’s just condensation.
If it has dropped, contact our support team and we’ll help you investigate.
