How to Winterize Your Hot Tub in Ottawa: A Step-by-Step Guide

Ottawa winters are beautiful, but brutal. If you don’t plan on using your hot tub during the cold season, it’s crucial to winterize it properly. Failing to do so can lead to cracked pipes, damaged pumps, and costly repairs come spring.

Whether you’re in Ottawa, Stittsville, Barrhaven, or nearby areas, this guide walks you through how to winterize your hot tub the right way. Follow these simple steps or contact Hot Tub Rescue Ottawa for professional help with seasonal shutdowns.

Why Winterizing Your Hot Tub Matters

Leaving water in your hot tub during freezing weather, even just a little, can cause serious damage. Ice expands in plumbing lines, pumps, and jets, leading to cracks and leaks that are expensive to repair.

If you won’t be using your spa for more than a few weeks in the winter, it’s better to shut it down completely and protect it from the elements.

Step-by-Step: How to Winterize a Hot Tub in Ottawa

Step 1: Power Off the Hot Tub

  • Turn off the breaker at the main electrical panel.
  • Double-check that the spa’s control panel is dark and all systems are off.

Step 2: Drain All the Water

  • Use the spa’s built-in drain valve or a submersible pump to remove all water from the tub.
  • Open the air jets and diverter valves to release any trapped water.
  • Don’t forget to drain the heater and blower lines (if your model has them).

Step 3: Remove and Clean the Filters

  • Take out your spa filters and clean them thoroughly.
  • Store them indoors for the winter to prevent freezing or cracking.
  • If they’re near the end of their life, plan to replace them before reopening the tub in spring.

Step 4: Blow Out the Lines
This is a must in Ottawa’s harsh climate. Use a shop vac or air compressor to blow out water from:

  • Jet lines
  • Suction lines
  • Drain lines
    Keep repeating until no more water comes out.

Step 5: Add Antifreeze (Optional but Recommended)

  • Use RV-grade, non-toxic antifreeze, not automotive antifreeze.
  • Pour it into the jet lines, suction ports, and pump housing to protect against residual moisture freezing.
    Note: If you’re unsure, this step is best handled by a professional hot tub technician in Stittsville or Ottawa.

Step 6: Clean and Dry the Interior

  • Wipe down the entire shell of the spa.
  • Remove any remaining water with towels or a wet/dry vac.
  • A dry tub is a safe tub.

Step 7: Secure the Cover and Add Insulation

  • Clean the hot tub cover with a spa-safe vinyl cleaner.
  • Check for tears, cracks, or weak spots, replace if needed.
  • Lock the cover in place and consider adding a spa cover cap or thermal blanket for added insulation.
