How to Choose a Hot Tub Repair Kit

When dealing with a  hot tub puncture, the size of the leak plays a role in which repair kit you choose. If you have just a small leak or minor crack, you won't need as much sealant as if you have a larger crack or hole in your hot tub. When you repair a hole in a hot tub, you need to be sure you adequately seal the problem so that you aren't back to square one once you put the water back in.

If you have a large leak, you may want a kit that comes with a large brush, but if it's a small leak, a kit with a small squeeze bottle is probably a better fit.

The material your hot tub is constructed from is another thing to consider. If you have an acrylic hot tub, you want something that repairs the crack, but that also matches the colour of the spa so that you can't see it once it's fixed. If you need an inflatable repair kit, the sealant will be different and will be more focused on the repair rather than the appearance since it will likely blend in with the surface of the spa.

Benefits of a Hot Tub Repair Kit

Spoiler.....  its way cheaper!

The main benefit of hot tub crack repair is the do-it-yourself perks. You can get the job done on your own time without having to wait for someone to come to your home and assess the damage and determine the best course of action. You can also save quite a bit of money by fixing a hot tub puncture yourself. For just the cost of the kit, you can solve the problem without having to pay for labour and a service call. Finally, a do it yourself job enables you to continue using your hot tub and prolongs its overall lifespan.

How to Use a Hot Tub Repair Kit

When you are ready to do repairs on your hot tub, it's vital to follow the pool repair instructions that come with the kit you choose. This ensures that the crack or leak is properly fixed and doesn't lead to further problems. At the same time, it's important to refer to the owner's manual for your hot tub as well to be sure you've chosen the appropriate patching kit and that you aren't going to cause further damage by repairing the problem yourself.

What you will need 

  1. Soap and water
  2. Underwater adhesive if its not included

Step 1 - Finding the Leak

According to the Lay Z spa repair guide, the first step is to find the location of the leak. Turn the spa off and use a pen to mark the location of the leak. If the leak is under water, look for bubbles that will tell you where it is. If it's above the water, it may be a bit more difficult to find. To make it easier, spray the area, working in small patches, and watch for bubbles. If you see them, you've likely found where the air is coming from. You can also listen for air leaks which make a hissing sound to tell you where the leak is located.

Step 2 - Clean and dry the area

Once you've found the leak site, clean the area well and allow it to dry.

Step 3 - Fix the Leak

Use the appropriate puncture repair kit to mend the problem. Allow at least 30 minutes for the patch or adhesive to cure before using your hot tub. Obviously the longer the better!

Important point to remember 

Remember that fixing a leak yourself could forfeit your warranty so be sure to check first before attempting any repairs on your own. Once you've checked then following the manufacturer’s instructions is vital if you have any comebacks and need to speak to them, they will want to know glue and patch and probably the exact repair kit you used in order to help further.
