How_to_Drain_and_Clean_a_Hot_Tub_&_Jacuzzi

For many people, one of the best ways to relax and unwind after a long day at work is by taking a dip in a hot tub or Jacuzzi. The warm and bubbling water can do wonders for the tired body and mind. However, nothing can ruin such a moment faster than climbing into a hot tub and finding it covered with ugly stains and scum marks. To prevent these yucky scenarios from occurring (and ensure that your hot tub operates smoothly and lasts for a long time) you must clean your hot tub thoroughly and regularly. That said, here’s our guide on how to drain a hot tub and how to clean a hot tub along with some advice on how often you should do these to ensure that your hot tub is always ready and fit for use.

How to Drain Your Hot Tub

To prepare your hot tub for cleaning, the first thing you need to remove the water from it. However, this is not as simple as draining the water with a hose or a pump since some other factors need to be taken into consideration. Don’t worry, it isn’t that difficult either.

1. Flush the Pipes

Hot tubs have dozens of jets, pipes, and hoses all of which can house a gooey and sticky substance known as a biofilm. This substance develops in your hot tub’s plumbing system regardless of whether your water chemistry is at the right levels or not.

Biofilm in itself is not dangerous, but it does serve as a source of food and nutrition for different types of bacteria that may find themselves in your hot tub like Staphylococcus aureus (which causes hot tub folliculitis) and E. coli (which causes intense stomach illness).

To get rid of the biofilm in the lines (and consequently, the bacteria thriving on them), you’ll need to flush the tub’s plumbing system using a line flush product that should be available in your local pool supplies store.

Before using the line flush product, be sure to read the instructions on the label. Sometimes, you’ll only need to let the product circulate in your hot tub’s lines for twenty minutes or so to remove the biofilm. However, if you haven’t cleaned your hot tub for quite a while now, you may need to let the line flush product circulate for several hours before it can effectively break down the biofilm.

2. Turn Off the Electricity

Before you drain the water out of your hot tub, make sure that you turn off the hot tub heater. Look for the dedicated switch at the mains supply and switch it off as well. This is so you can avoid any untoward incident or injuries that may be caused by a bad mix of water and electricity (some of which may even be fatal.)

3. Drain the Water

Some hot tubs come with their own drain hose while others don’t. If your hot tub manufacturer didn’t provide you with one, you can use a regular garden hose provided that it fits perfectly with the hot tub’s drain spout (located at the bottom of the hot tub). When attaching the hose to the drain spout, make sure that it’s attached firmly to prevent the water from leaking out while you’re draining the tub.

Also, remember to stretch the hose and put the end (where the drained water will come out) somewhere where it won’t cause your backyard to flood. If your hose is long enough, you can simply hold the hose and water your plants and trees with the water.

Once the hose is set, you can now open the spigot and let the water drain out.

4. Removing the Remaining Water

Even if the water has stopped flowing out of the hose, it doesn’t mean that your hot tub is completely free from water. There will still be a few droplets of water remaining on the surface of the hot tub’s shell, jets, and lines. To get rid of these grab a soft rag or a mop and try to wipe away as much of the remaining water as possible. Don’t worry if you can’t get them all out since they’re most likely to evaporate in a few hours if the sun’s out and shining or a day or two if you’re draining your hot tub during the colder months of the year.

How to Clean Your Hot Tub

After you’ve drained all the water out of the hot tub, you can now start cleaning it.

1. Remove and Clean the Filter

You must clean your hot tub filter regularly since it is a crucial component that is responsible for keeping your hot tub water clean. Cleaning your hot tub filter also helps to improve its longevity so you don’t have to keep replacing them now and then.

Removing the Filter. To properly and safely remove the hot tub filter, you’ll need to consult with the owner’s manual that came with the hot tub when you bought it. If you inherited the hot tub from a previous owner or lost your copy of the manual, you can go to the manufacturer’s website and look for the instructions there. Just make sure that you indicate the model number of your hot tub to ensure that you get the correct instructions.

Wash the Filter. After you removed the filter, wash it with regular tap water. You can use a soft-bristled brush and a mild detergent to remove any dirt and debris that’s stuck in the filter. Just be careful when brushing the filter to avoid damaging its components. For tough dirt and grime, soak the filter in warm water and mild detergent to loosen them up before cleaning.

Inspect the Filter. After cleaning the filter, go over it and check for any signs of damage of wear and tear (this can be difficult to do when you don’t clean the filter first). If the filter looks okay or in good condition, you can continue using it for several weeks more. Otherwise, you’ll need to get a replacement since damaged or worn filters won’t be effective in keeping your hot tub water clean.

Changing the Filter. Regardless of how well and how often you clean your hot tub filter, you’ll have to replace it eventually as nothing can protect it against normal wear and tear. Experts usually recommend replacing your hot tub filter roughly every one to two years depending on how much you use your hot tub.

Reinstalling or Storing the Filter. If you are planning to refill your hot tub any time soon after you clean it, simply reinstall the filter back into the hot tub and reset the control system before filling the tub with water. On the other hand, if you won’t be using your hot tub for several weeks or months, then it might be a better idea to store the filter inside your house to protect them from any damage that may be caused by outdoor elements.

2. Wipe Shell’s Surface with a Cleaning Solution

Apply a hot tub cleaner to the hot tub’s shell using a sponge or a soft rag. These hot tub cleaners are generally available in most local pool supplies stores, if not then you may want to consider buying them online.

Some manufacturers recommend a specific kind or brand of hot tub cleaner for their products. If possible, you should the recommended cleaning solution since using a different product may damage the shell’s surface. If the manufacturer doesn’t recommend a specific cleaning agent, then it’s safe to assume that using any mass-produced hot tub cleaner is fine.

When cleaning your hot tub, be sure to conduct a visual inspection of the tub’s surface. Check the surface for any signs of cracks and if you see any, be sure to call the manufacturer for help in fixing these.

3. Deal with Stains, Lines, and Water Sports

You may notice that that there’s a line at the water level of your hot tub shell which looks pretty much the same as the water line in swimming pools. These lines are caused by the oils and lotions that buildup on the water’s surface and were washed onto the sides of the tub. Don’t worry though because they are quite easy to clean with the use of any regular hot tub shell cleaner. Just be sure to follow the instructions to ensure that the waterline and all the oil and stains are removed thoroughly.

4. Rinse and Wipe the Hot Tub Down

Rinse and wipe down the hot tub’s surface after applying a hot tub cleaner. Be sure to get every bit of the cleaner’s residue, otherwise, your hot tub will start foaming when you turn the jets on.

5. Protect the Shell

To ensure that that hot tub’s shell lasts longer, you should consider applying a sealant or protectant over its surface. Just like the cleaning agents mentioned above, these should be readily available in your local pool supplies store. These products give your hot tub a nice shine, making it look new and more sanitary. It also removes any streaking leftover from the cleaning process. Just wipe it on the shells using a towel or a rag and buff it a little to get that nice gleaming look.

6. Check the Clean Underneath the Hot Tub

Much of the hot tub’s mechanisms will be sitting underneath the tub. You’ll want to check this section of the tub too and clean it if necessary since it’s a nice, warm place for small critters to hide. You can use a long extension on your vacuum cleaner and suck up any cobwebs or debris. If you find any evidence of rodents nesting underneath the tub, you’ll want to consider calling an exterminator right away before they start chewing on your hot tub’s electronics and wires.

7. Clean the Hot Tub Cover

Hot tub covers are essential to keeping your hot tub protected from the outdoor elements. They are your tub’s first line of defense against the ultraviolet rays of the sun and excessive moisture from the rain and snow. Thus, you’ll need to spend some time cleaning your hot tub cover, too.

How Often Should You Clean Your Hot Tub

To ensure that your hot tub or Jacuzzi is always sanitary and fit for use, you’ll have to clean it regularly. It is an on-going project and is part of being a responsible hot tub owner. But just how often do you need to clean it anyway?

Twice a Week. If you use your hot tub several days a week, then you’ll want to clean it at least every three to four days. This will help any discoloration and cloudiness of the hot tub water, as well as prevent the buildup of grime and slime on the hot tub’s surface.

Once a Month. If you only use your hot tub sparingly, then cleaning it at least once a month should do.

Every 4-6 Months. If you rarely use your hot tub, then you can drain and clean your hot tub every 4 to 6 months.

Also, you should test the chemical levels on your hot tub water using testing strips. This will help you to determine which chemicals need to be adjusted to make sure that the water is fit for use. In general, you’ll want to check and balance the hot tub’s pH levels, alkalinity, and calcium hardness.

It is also recommended that you have your hot tub inspected by a certified hot tub technician. This will help to prevent future problems that can drastically damage mechanisms and stop your hot tub from working properly.
