There are not many things as frustrating as an inflatable hot tub that is leaking, and you can't find the leak at all.
Now, the majority of leaks are air leaks and are quite minor, to begin with. They will not cause you too many issues. Eventually though, if not treated correctly, they can develop into a rather big problem which will be nigh on impossible to repair properly.
Basically, if you believe your hot tub is leaking then you are going to need to go searching for that leak as soon as you can, and of course, deal with it as soon as you can.
Sadly, not everything is infallible. From time to time you may find that the air starts to escape that inflatable hot tub incredibly quickly, or even quite slowly.
If you find that the air is leaving the hot tub faster than it normally does then you need to go hunting for that leak.
Now, many people seem to be of the impression that they need all sorts of specialist equipment to find a leak in their hot tub. You don't. In fact, all you need is a small amount of water, some sort of liquid soap, and a spray bottle.
Mix up your water and a couple of squirts of the soap in your spray bottle. Make sure the soap is well-dissolved in the water otherwise it will not be effective.
Now, with your spray bottle, you are going to want to spray around that blow up hot tub. You will want to aim for the locations where you believe a leak may be occurring.
If the soap starts to bubble up on the surface then there is air being forced into it. This means you have a leak. To look for locations to 'spray' you will want to search for small black marks on the surface of the hot tub. Not all of these marks will be leaks though. In fact, very few of them are.
However, you are going to look for these inconsistencies in order to deal with any damage to the surface of the hot tub.
I suggest that you look for leaks in your hot tub every time you inflate it. This is because, as I said, the earlier the damage is spotted in the tub the easier it is going to be to deal with. If you leave it too long then you will find that it is nigh on impossible to deal with the problem.
Most small leaks can be patched up quite quickly using the right tools. They will not destroy the aesthetic appearance of your unit in the slightest. A small leak is prone to getting bigger; particularly if there is a lot of weight being placed into the hot tub at once.
How To Determine The Cause of Leaks In Inflatable Hot Tubs
If I had to narrow it down to 4 reasons why inflatable hot tubs develop leaks, they would be
Frequency of usage
Pinch of the outer part of the tub via a sharp object
Just like humans, we cannot be as active as our younger years compared with our old age, thus, a hot tub also declines in performance with age. Also, if there is an increase in the frequency of usage, the tub will most likely feel the effect the most.
Maintenance is very important when it comes to having a properly functioning hot tub. Thus, if the tub lacks maintenance, there is a high probability of leaks occurring.
If a sharp object should pinch the outer part of an inflatable hot tub, leaks will occur. A leak can either be large or small depending on the cause of the leak.
Common Hot Tub Parts Where Leaks Occur
2 most common places where leaks occur in an inflatable hot tub are;
Pump sealing and
The heating assembly
Leaks occur in the pump sealing with usage and age of the tub. If you discover that the pump sealing is where the leaks occur, then, it is either the pump sealing is repaired or replaced.
The option of the replacement or repair depends on what the professional recommends. My point is call in a professional if the cause of the leak is the pump sealing.
Similarly, leaks occur in the heating assembly with usage and age of the tub.
2 of the most common places where leaks occur in the heating assembly will be;
The valves and
The union fittings
As with the pump sealing, call in the service of a professional if you find out that the valves are the cause of the leaks. This professional will also advise you on whether you should repair or change the valves.
As regards the union fittings, most likely the fittings might just have become loose, so all you have to do is tighten the fittings back with your hands. It is not advisable to use a wrench for this, this is because using a wrench can cause damage to the heater.
How To Be Sure That There Is A Leak
There are 2 methods to accomplish this without involving the help of any professional;
This involves 3 steps. They are;
Fill the tub with water and mark the level of the water
Do not use the tub for at least one hour, then; check your marker to see if there is a drop or not.
The level of the drop corresponds to how high or low the level of a leak is
To use this method, you will the following 5 materials;
Water, Vinyl Pool Patch, Spray Bottles, Soap and Paper Towel
Once you have these materials, here are the steps you should follow;
Fill the spray bottle with water and soap, then, shake vigorously. This is important in order to have a very good mix.
Spray the suspected area with the mixture you have created. This is to see if there will be an appearance of any bubble. If there is a bubble, it implies that the leak is confirmed.
Mark this area where the leak is
Allow air to completely get out of that portion of the tub where there is the leak.
Apply a patch to the affected area
Use the paper towel to dry the area. This is to ensure that the patch fixes properly
How To Use The Patch
Each manufacturer has specific instructions on how to use their brand of the patch. However, 4 of the most the common instructions are;
Add adhesive to the back of the patch and stick the patch to the affected area.
Leave the patch for at least 2 to 3 hours before adding water
Lastly, spray the area again to observe if there is going to be a bubble or not. if there are no bubbles, then, the leak has been properly fixed. If otherwise, then you either repeat the process or call for professional help.
