How to close your spa for the winter - Trevi Guide

Autumn is here, and if you're a spa owner, it's time to decide whether to keep it running through the cold season or close it. If you choose to close it, here's a step-by-step guide to effectively winterizing your spa.

1. Keep the water clean until shutdown

Before closing, it's essential to keep the water clean and warm for as long as possible. This will make closing easier and prevent the build-up of dirt or algae.

2. Cleaning the spa

Before draining the water, use a pipe cleaner such as WHIRL PRO. Add it to the water and leave it to work for four hours, activating the pumps every hour.

Note: Be sure to remove headrests to protect them from chemicals.

3. Draining the water

You can empty the water with a submersible pump or use the bottom drain. If you opt for the drain, allow up to 8 hours for complete emptying. Make sure the spa cover remains open during this operation.

4. Cleaning filter cartridges

Remove the cartridges and clean them with a product such as CARTRIDGE CLEANER. Soak them in the cleaning solution for one hour, then rinse thoroughly. Store indoors for the winter.

5. Removing jets

Take photos of the jets to make it easier to replace them in the spring. Unscrew them carefully and store them indoors. This also allows you to clean them over the winter.

6. Removing residual water

Even after draining, some water will remain in the pipes and on the seats. Use an industrial vacuum cleaner (e.g. Shop-Vac) to remove this residual water, especially from the bottom of the spa and around the seats.

7. Drying pipes and valves

Depending on the configuration of your spa, you may need to dry the valves and piping. To do this, remove the valve covers and use the vacuum cleaner in blower mode to remove water from the pipes.

8. Adding antifreeze

To protect your spa against winter temperatures, pour antifreeze into the skimmers and jets. This ensures that any remaining water will not freeze and damage the spa's internal components.

9. Final cleaning and protection

Clean the spa's acrylic and cover before closing for the winter. Place a support in the center of the spa (such as a block of Styrofoam) to prevent the cover from collapsing under the weight of snow. Finally, cover your spa with a specially designed protective cover.

10. Check with your insurer

Before finalizing closure, contact your insurer to make sure your spa is covered for winter damage. This will help you avoid unpleasant surprises during the cold season.
