How to determine if you have a leak in your inflatable hot tub

How to determine if you have a leak in your inflatable hot tub

There are several things to look for if you suspect a leak in your inflatable hot tub. 

One of the first things to check out would be an inflated water level inside the hot tub, especially where it attaches with suction cups or other securing devices. If any sections show deflated areas, there is a strong chance of a leak in the inflatable hot tub.

Another part of this process would be to look for any air pockets or other signs where air might have leaked out from inside the lining of the spa. If you see any of these signs, then there is a good chance that the inflatable hot tub has a puncture.

Another thing to look at would be how fast it takes for air pockets to re-inflate after being compressed by water pressure inside or outside the spa. If air bubbles rise quickly and go away just as fast, then there is a good chance that one of the hoses has come loose.

How to find an underwater puncture

An underwater puncture is in the inflatable hot tub lining. Often, this kind of crack cannot be seen because it’s underwater. However, you can look for leaks by applying the soapy solution to areas that might have leaking seams or cracks and then looking carefully for bubbles that indicate a hole in your inflatable hot tub liner. If you find bubbles around the seams and you think you’ve found a hole in your inflatable hot tub liner, then try using an underwater sealant to patch it. 

If this doesn’t work, then there might be a crack or tear too big for an underwater patch to fix, and the only way is to replace the vinyl lining with a new one.

How to find a puncture on the outer wall of your hot tub

If you are having trouble finding a leak in your hot tub, look for bubbles at the seams of the outer wall. If there is no visible puncture on the outside, check inside by removing any plugs or caps. This will allow all water to escape from within, revealing where it’s originating from if air pockets are present. Be sure to check each plug or cap after removing it.

Common hot tub parts where leaks occur

Common hot tub parts where leaks occur

Inflatable hot tub leaks can occur anywhere in the system, but they are easy to find if you know where to look for them.  

Inflatable hot tubs have several common parts where leaks can occur. Leaks often start at connecting two pipes or when a line enters or exits an inflatable plug. Often, these types of leakage will be visible from outside the in-ground vinyl liner, which means you may see bubbles in your pool if there is a leak.

How to repair an inflatable hot tub puncture

Step 1 – Identify the puncture

If you notice a leak in your inflatable hot tub, the first thing to do is identify where it’s coming from. You can find out by carefully submerging and then inflating the affected area with air. There’s definitely an issue if it doesn’t hold any pressure at all or only holds for a few seconds before deflating again.

Once you’ve identified the puncture, it’s time to move on to step two and start fixing things up.

Step 2 – Repair the hot tub leak

After identifying the source of the leak, you should repair it immediately. You can do so by applying a patch to your inflatable hot tub. The process is simple and doesn’t require any special skills or tools.

  • Attach an adhesive patch to the punctured area.

The first step in repairing a hole in an inflatable hot tub is to attach a patch. You can purchase adhesive patches from your local hardware store or online hot tub supply retailer.

  •  Sand the area around the puncture.

For an adhesive patch to hold, it must be attached directly onto smooth, clean fabric without bumps or ridges underneath it. This means that you need to sand the area around the puncture before applying your adhesive patch.

  • Apply glue to the back of the patch and attach it directly onto the hot tub fabric.

Once you’ve applied some fine-grit sandpaper around the hole, use a clean rag or sponge to wipe away any debris that may have accumulated during this process. Next, apply glue to the back of your adhesive patch and attach it directly onto the hot tub fabric.

  • Smooth out glue around the puncture area with a squeegee or credit card.

Make sure you smooth out any excess air bubbles to create a proper seal between your inflatable hot tub and its patch. For this, use either a rubber squeegee or a credit card.

  • Let the glue dry for 24 hours before using your inflatable hot tub again.

After letting all of this set, make sure to allow it to dry completely (for at least one day) before reinflating and testing out your hot tub. If done correctly, nothing should leak through.
