10 Steps to Winterize Your Hot Tub

We certainly hope you can keep your hot tub open year-round. After all, what’s better than a dip in your spa on a cold winter evening? Not much! But if you do choose to close your hot tub for the winter, be sure to follow these ten steps to winterize your hot tub properly. Doing so will help avoid broken plumbing from freezing water, and make for an easy opening next year.

1. Turn Off The GFCI Circuit Breaker

Before draining or servicing your hot tub, it is critical that you shut off power at the breaker.

2. Remove Your Hot Tub's Side Panel

Most hot tubs have an access door on the side. In some cases, you will have to remove the entire side panel to access the hot tub equipment.

3. Attach A Garden Hose To The Drain Hose

Inside of the equipment access area, there will be a hose attachment that can be used to drain your hot tub. Connect a garden hose and turn the valve to drain the water. If you are left with some water in your spa that does not drain through the hose, use a wet-vac to remove it.

4. Loosen Unions On The Heater And Pumps

You will need to loosen the unions to drain any water in the lines. Keep in mind that your hot tub might have multiple pumps. Repeat this procedure on all pumps so that you can drain the water from the plumbing lines.

5. Remove The Drain Plug From The Pumps

You want to remove the lowest drain plug from the front of each pump. This will allow water to drain from inside the pump.

6. Use A Wet-Vac To Remove Water From The Lines

You will need to remove water from hot tub lines, or else they could freeze and damage your plumbing. Insert a wet-vac into each drain, jet face, union, suction, and filter cavity. The wet-vac should be placed in each for 10-15 seconds to ensure all water is sucked out.

7. Replace Drain Plug On Pumps

Once all of the water is sucked out of your hot tub lines, replace the drain plug on the pump. Tighten all unions and ensure that all gate valves are open.

8. Add Hot Tub Antifreeze

Pour one gallon of hot tub antifreeze into the top of each pump, and also one gallon into your filter cavity.

9. Replace The Hot Tub Equipment Access Panel

10. Close The Hot Tub Cover
