Beginner’s Guide: How to Maintain Your Hot Tub 

It’s no secret that hot tubs can be pretty expensive. Not only do you have to purchase the initial tub, but you also have to factor in the cost of installation, running electricity to the site, and of course, the cost of chemicals and other maintenance items. Given all of these factors, it’s no wonder that people are always looking for ways to save money on their hot tubs.

One way to do this is by maintaining your hot tub on your own. While this may sound like a daunting task, it’s not that difficult – and it can save you a lot of money so you can enjoy it for years to come. 

There are a few ways to maintain and prolong the life of your hot tub; let’s go through them one by one.

1. It Starts With Keeping Your Hot Tub Clean

This may seem like an obvious one, but it’s worth repeating. You should clean your hot tub regularly – at least once a week, and preferably more often if you use it frequently.

Emptying the Water

The first step in cleaning the hot tub is to empty it of all water. Once the tub is empty, you should scrub all surfaces with mild soap and warm water. Be sure to pay special attention to areas where dirt and debris may have accumulated. After scrubbing the tub’s surfaces, rinse all soap and residue with clean water.

Using a Hot Tub Filter

Another way to do this is to use a hot tub filter. Filters are designed to remove all of the tiny particles that can get into your tub, and they can be a great way to keep your tub clean. Hot tub filters should be cleaned every few weeks – more often if you use your hot tub frequently.

Draining and refilling the tub

If your hot tub is not being used for an extended period, it is important to drain and refill it. This will help to keep the water clean and free of contaminants. To drain your hot tub, start by turning off the power. Next, locate the drain valve and open it to allow the water to drain. Once the water has drained completely, close the drain valve and remove any hose that may be attached.

Now it’s time to refill the tub. Turn on the power to the tub and open the fill valve. Allow fresh water to flow into the tub until it reaches the desired level. Close the fill valve when finished, and enjoy your clean hot tub!

2. Keep Water Circulating in Your Hot Tub

There are a few different ways to circulate the water in your tub. One option is to use a hot tub pump. These are designed to circulate the water in your tub and can be a great way to keep the water clean. Stagnant tub water encourages bacterial growth, so a hot tub pump is a great investment in hot tub maintenance. 

3. Understanding Hot Tub Water Chemistry and How Chemicals Affect Hot Tubs

One of the most important things you need to understand about hot tubs is the role chemicals play in keeping your tub clean. Chemicals are used to disinfect the water and remove contaminants.

However, it’s essential to understand that not all chemicals are created equal. Some chemicals can actually be harmful to your hot tub, so it’s important to select the right chemicals for your tub.

The three essential chemicals in hot tub water are Chlorine, pH, and Alkalinity.

Chlorine is used to disinfect water by killing bacteria and other harmful organisms, while pH measures the water’s acidity and should be within the 7.2 to 7.6 range. On the other hand, Alkalinity helps stabilize the water’s pH and should be kept in the range of 80 to 120 ppm. 

The best way to select the right chemicals for your hot tub is to consult a professional. A professional can help you choose the right chemicals for your tub and can also help you understand how to use them properly. Know what you need already?

4. Put the Cover on Your Tub After You Finish

Once you’re done using your hot tub, always put the cover on. Additionally, it would be best if you also made sure that the cover is the right size. If the cover is too small, debris and contaminants could enter the tub. On the other hand, if the cover is too large, it could cause the tub to overheat. 

A cover will keep dirt, debris, and animals out of the tub and help keep the water warm, saving you money on your energy bill. Then, when you’re ready to use the tub again, remove the cover and enjoy!

Taking care of a hot tub is not that complicated. With a little knowledge and effort, you can keep your hot tub in pristine condition for years to come. Following the tips in this article, you’ll be well on your way to being a hot tub maintenance pro.
