Simple Steps to Drain your Hot Tub

The steps you will take to drain your hot tub yourself is generally the same. Whether it is the two-person hot tub or any other kind, the process remains applicable to all types.

Step 1: Flush the Plumbing Lines of your Hot Tub

Step 1 Flush the Plumbing Lines of your Hot Tub

There are line flush products used to drive out the dirt and slime that have settled in the tubes over time. Driving out the gunk is the reason behind this step as it is in this slimy environment that most of the bacteria and fungi we spoke about flourish.

You should add the line flush product in the tub while the hot tub is still operating. When the hot tub is running, it ensures that the line flush product goes through every plumbing line in the hot tub.

The manufacturer specifies instructions for the addition of the line flush product on the body of the product. The amount of time to allow for the circulation of the product through the lines is also specified.

In peculiar cases where your hot tub has been dirty for a long time, you may have to use your discretion to allow more time for the line flush product to circulate properly through the pipes before you move to the next step of draining your hot tub.

Step 2: Switch off the Power Supply to your Hot Tub

Step 2 Switch off the Power Supply to your Hot Tub

Turn off the hot tub after you have flushed the plumbing lines and ready to drain off the water. This step is essential as it is not suitable for the life of the tub to have it running while empty.

There is also the danger of possible electrocution when you are draining the tub containing such amount of water without first turning it off.

Step 3: Remove the Drain Plugs to allow the Water Leak Out from the Hot Tub

Remove the Drain Plugs to allow the Water Leak Out from the Hot Tub

The drain plugs are located right at the base outside the hot tub. Disconnect the plugs and attach the garden hose in its place to direct the water either to the nearest drain, garden, or wherever you want it to go.

There are submersible pumps you can use to drain the water more quickly if you cannot wait for the much slower drain plugs where the water pressure flows at the force of gravity. These pumps are available for sale at local pool-supplies stores.

While using the submersible pump, you should attach the hose to the pump and direct it to where you wish the water to go. Set the pump on each of the sits to suck up any residual water left in their grooves.

To drain the hot tub even much faster and save time, you can apply both methods simultaneously to get the water out.

Step 4: Clean the Filters

Step 4 Clean the Filters

To further save time, do the cleaning of the filters while the water is draining off the hot tub. Unscrew the filter plugs and take out the filters from the hot tub.

You will notice the color change as a result of dirt or gunk on the hot tub filter. Use water to wash them clean.

You may need to soak the filters in vinegar and water solution overnight if they are particularly filthy but not too severely coated in slime to consider a total replacement.

It is an ideal practice to replace the filters of your hot tub at least once every year.

Step 5: Blow out the Pipes or Plumbing Lines

Step 5 Blow out the Pipes or Plumbing Lines

This step is particularly essential if you did not flush the plumbing lines of the hot tub as you ideally should in step 1.

To blow out the pipes, you should unscrew the filter stands from their base to expose the holes into the internal plumbing. Use the plugs to close all but one of the openings left by the filter stands.

Plug the hose of your shop vacuum cleaner into the last hole and switch it to blow action instead of suck action. Turn the vacuum cleaner on to blow out the pipes. Repeat this process with all the openings while each time, plugging all except the one you want to blow out.

You will notice some debris of dirt or gunk pumped out of the pipes along with residual water into the tub.  Switch the vacuum cleaner into sucking action and use it to suck up the remaining water left in the areas the pump cannot reach.

Step 6: Clean the Interior of the Hot Tub

Step 6 Clean the Interior of the Hot Tub

Spray a cleaning solution in the tub and wipe it clean with a towel. A household cleaner like a vinegar and water solution could be used for this as well.

There are adsorbent spa cleaning products specially designed for this kind of cleaning. It may be necessary to rinse the tub with water and wipe it again with the towel to get off all the cleaning solutions.

Step 7: Refill the Hot Tub

Step 7 Refill the Hot Tub

Replace the filter stands. Put the filters back and replace the caps on all except the one through which you will pump water back into the system.

Insert a regular garden hose into the through it and allow water to flow into the unit. Once the tub is full, pull out the garden hose and replace the cap of the last filter.

Step 8: Add the Purification Chemical of Your Choice

You can choose any of the purification systems mentioned earlier in this article. The most common ones include chlorine, ozone, bromine, or Salt Water System.
