Did You Know?

1. In the 1960s, the first hot tubs were made from repurposed oak wine barrels and were heated using the firewood burning inside the barrel.

2. The origin of the term “hot tub” can be traced back to Japan, where they are referred to as “ofuro,” meaning “bath.”

3. When winterizing a hot tub, it is important to drain and clean the pipes thoroughly to avoid any potential damage from freezing water.

4. To ensure your hot tub is fully winterized, remove any accessories such as covers, steps, or handrails, and store them in a dry place to prevent damage caused by cold temperatures.

5. Some hot tubs have a unique feature called a freeze protection system, which automatically activates the heater when the temperature drops below a certain level to prevent freezing.

Disconnecting Power And Draining Lines

Winterizing a hot tub is essential to ensure its longevity and protect against freezing temperatures. Here are the steps to properly winterize a hot tub:

  1. Disconnect the power supply: Start by disconnecting the hot tub from the power supply. This reduces the risk of accidental electrical mishaps during the winter months.
  2. Drain the lines: Locate the main drain valve and connect a garden hose to it. Open the valve and let the water flow out until the tub is completely empty. Make sure to drain all the water from the tub and the lines to prevent freezing and potential damage to the plumbing system.

Removing Water From Plumbing Lines

After draining the tub, it is essential to remove any remaining water from the plumbing lines. To do this, a shop vac or wet/dry vacuum can be used. Attach the vacuum to the plumbing lines and use it to suction out any water that may still be present. By thoroughly removing all the water from the lines, it will help prevent freezing and potential damage to the pipes during the winter months.

  • Use a shop vac or wet/dry vacuum to suction out any remaining water from the plumbing lines.
  • Remove all water from the lines to prevent freezing and potential damage to the pipes.

It is important to properly remove all water from the plumbing lines after draining the tub. This will help prevent freezing during winter months.

Draining The Pump And Opening Unions

To properly winterize the pump and heater, you must ensure that they are drained completely. Follow these steps:

  1. Open the unions on the pump and heater: This will allow any leftover water to drain out.
  2. Remove the drain plugs from the pump: By doing so, you can fully drain the water from the pump.
  3. This step is crucial in preventing any water from freezing inside the pump, which can potentially cause damage.

Remember to perform these steps before the onset of winter to protect your pump and heater from freezing temperatures.

Storing The Power Pack Indoors

It is highly recommended to store the power pack indoors for the winter months. Storing it in a temperature-controlled environment will help protect it from freezing temperatures and potential damage. Additionally, by storing the power pack indoors, it will be readily accessible for future use and maintenance.

Treating And Cleaning Wooden Cabinets

To maintain the aesthetic appeal and prolong the lifespan of wooden cabinets, it is essential to clean and treat them with a weatherproof sealer. Start by thoroughly cleaning the cabinets to remove any dirt or residues that might have accumulated. Once clean, apply a weatherproof sealer to protect the wood from moisture and harsh winter conditions. This will help prevent any potential warping or damage to the cabinets.

Properly Covering And Maintaining The Vinyl Thermal Cover

The vinyl thermal cover is a crucial component in winterizing a hot tub, as it helps regulate water temperature and prevents energy loss. Here are some key steps to ensure proper winterization:

  1. Drain the hot tub completely and store the power pack indoors for safety.
  2. Close the cover properly to minimize heat loss. Check for tears or damages that could let cold air inside.
  3. To protect the cover, place a large board on top to distribute the weight of snow or ice during winter.

Maintenance of the vinyl thermal cover is essential throughout the winter season. Take these steps to ensure its longevity:

  1. Regularly remove any snow or water accumulation on the cover to prevent leaks or collapse.
  2. Snow and ice can cause damage, so remove it promptly and ensure the cover remains intact.

In summary, winterizing a hot tub is crucial. Follow these steps, including disconnecting the power, draining the lines, storing the power pack indoors, treating and cleaning wooden cabinets, and properly covering and maintaining the vinyl thermal cover. Seek professional assistance if needed and refer to more detailed instructions for a thorough winterization process.
