How Often Should You Change The Water in the Hot Tub?

Alright, so this is one of those topics that a lot of people don’t really want to think about.  Why?  Because it requires effort and scheduling.  Sure, your hot tub is your spot of relaxation and forgetting about the world, but that doesn’t mean that you get to simply forget about how to take care of it!  Both your financial investment and your health are depending on that, too.  So, let’s tackle it head-on and get back to relaxing, okay?

How often should you change the hot tub water?
    The standard, fast answer is that you should change your hot water (as in, completely drain and refill fresh) approximately every 3 months of use.  However, this number is going to be a little different for each hot tub, because there are a few factors that go into how that approximate number is calculated!

Factors that impact the timing
    The first two items of the list below are going to be used to help you figure out the actual timing.  The third item is more about your own comfort and sanitation practices!

• Size of your tub: While a smaller hot tub takes less water, it will have to changed more often than a larger one because there is also less water being recycled over and over again.

• Number of people in your tub: If there is only one person using it regularly, this means you change it less frequently than if you regularly have 8 people in your tub (even though it’s bigger).  Don’t worry about the exact number, here, just do an average.

 

• How often you use it: The amount of people and the amount of times that you (and they) use it should also factor in socially.  Simply put: the more you use it, and the more people you have in it, the faster the water goes stale.

The math
    What a lot of people do is turn this into a simple math equation to take the guesswork out of it.  This math equation would be: the hot tub volume divided by 3 and then divided by the amount of people in your tub.  This will give you a number of days.  So, every time that number of days goes by, change your water.

The importance of changing your hot tub water
    Let’s say you get the math done and the final answer is 20.  But, you don’t feel like changing your tub water every 20 days.  Well, technically you don’t have to.  But, you’ll soon get filmy, smelly and foamy water.  Not only is it uninviting, it’s also asking for trouble when it comes to bacteria and germs.  
    It also puts a lot more work on your system and can create buildup in your pipes and filter.  This means more repairs and leaks. 

    Sure, it takes time and effort to drain and refill your hot tub, but it will be worthwhile when you can enjoy fresh, healthy water that is going to truly bubble away your troubles and concerns.
