How to Fix Leaking Jacuzzi Jets

How to Fix Leaking Jacuzzi Jets

Unfortunately, if your jets are not functioning properly, it can be difficult to get the most out of your Jacuzzi. In this blog post, we’ll show you how to fix leaking Jacuzzi jets yourself using some simple tools and techniques. So read on and get ready to take your Jacuzzi experience back to where it should be.

8 Common Causes for Leaking Jacuzzi Jets

1. Incorrectly Installed Jets

One of the most common causes of leaking Jacuzzi jets is that they were not installed correctly in the first place. If the jets are not properly sealed, then water will be able to leak through. This is why it is important to ensure that your Jacuzzi jets are installed by a professional. If your jets are already installed, you can try resealing them using a high-quality sealant.

2. Cracks in the Jet Body

Another common cause of leaking Jacuzzi jets is cracked in the jet body. Over time, constant exposure to water can cause the jet body to develop cracks, allowing water to leak through. In some cases, cracks can also develop in the seals around the jets, which will also cause leaks. The best way to fix this problem is to replace the jet body or seals.

3. Worn Out Seals

Over time, the seals around your Jacuzzi jets can become worn out and no longer provide a tight seal. When this happens, water will be able to leak through and cause problems. You may need to replace the seals on your Jacuzzi jets every few years to prevent leaks. If possible, it’s a good idea to purchase seals that are specifically designed for Jacuzzi jets. That way, you’ll know they’ll fit properly and provide a good seal.

4. Loose Screws

If any of the screws holding your Jacuzzi jets are loose, this can also cause leaks. Water can seep through even the smallest opening, so it is important to ensure that all the screws are tightened securely. When adjusting the screws, be careful not to over-tighten as this can strip the threads and worsen the problem.

5. Damaged O-Rings

The O-rings around your Jacuzzi jets play an important role in keeping water from leaking out. If these O-rings are damaged, then they will no longer be able to do their job, and water will be able to escape. You may need to replace the O-rings on your Jacuzzi jets every few years to prevent leaks. If you want to ensure that your O-rings are in good condition, you can lubricate them with silicone grease.

6. Clogged Drainage Holes

The drainage holes on your Jacuzzi jets can become clogged over time, which can cause water to leak out. To prevent this, you should regularly clean the drainage holes using a small brush or toothpick. Make sure that the holes are clear and free of any debris. You can also use a small drill to enlarge the holes if you need to.

7. Broken Pump Impeller

If the pump impeller on your Jacuzzi is broken, then this can also cause leaks. The pump impeller is responsible for moving water through the jets; if it is broken, water will not be able to move properly and will leak out instead. You will need to replace the pump impeller if it is broken to fix this problem.

8. Improperly Connected Hoses

If any of the hoses connecting your Jacuzzi jets are not properly connected, this can also cause leaks. Especially the hose between the pump and the jets. If this hose is not properly connected, then it can cause water to leak out. Ensure all hoses are properly connected and there are no leaks.

If you’re having trouble finding the source of your leaking Jacuzzi jets, you can always contact a professional for help. They will be able to inspect your Jacuzzi and determine the cause of the leaks. Once they know the cause, they can fix the problem and prevent it from happening again.

10 Easy Steps on How to Fix Leaking Jacuzzi Jets 

Step 1: Turn Off the Power

Before you do anything, turn off the power to the Jacuzzi. Locate the breaker box and flip the switch that corresponds to the Jacuzzi. This will prevent you from getting electrocuted while working on the Jacuzzi. Make sure that the power is off by testing the jets; if they don’t work, then the power is off.

Step 2: Remove the Access Panel

You will need to remove the access panel to get to the jets. The location of the access panel will differ depending on the Jacuzzi model you have. Set the panel aside in a safe place. Make sure there is no water near the access panel, as you don’t want to drop it into the water accidentally. If the access panel is wet, dry it off with a towel.

Step 3: Disconnect the Water Supply

Locate the water supply line and disconnect it from the Jacuzzi. Make sure to have a bucket or something to catch the water when you disconnect the line so it won’t get all over the place. Once the panel is removed, take a look at the jets and see if anything is blocking them. If there is, remove whatever it is so that the jets are clear.

Step 4: Inspect the O-Ring

Inspect the O-ring to see if it is damaged in any way. This small, circular piece of rubber creates the seal between the jet and the tub wall. Over time, it may become cracked or worn and lead to leaks. To inspect the O-ring, start by removing the jet cover. Then, carefully take out the O-ring and examine it for any signs of damage. If necessary, replace it with a new one before reassembling the jet. Finally, don’t forget to check for any cracks or damage in the jet housing itself, as this can also cause leaks.

Step 5: Replace the O-Ring

If the O-ring needs to be replaced, then do so now. First, ensure that you get the right size O-ring for your Jacuzzi. To replace it, start by removing the old O-ring. Clean out the housing thoroughly and then apply a generous amount of lubricant to the new O-ring. Please put it in place and make sure that it is seated properly. If possible, the O-ring should be replaced with a new one every few months to prevent leaks.

Step 6: Cleaning the O-rings 

Cleaning O-rings is a pretty simple process. Just soak them in warm soapy water for a few minutes and then scrub them with a brush to remove any dirt or debris. Once they’re clean, dry them off and put them back in place. You need to ensure that the O-rings are properly lubricated; otherwise, they will cause leaks.

Step 7: Tighten Bolts and Screws

After you’ve replaced and cleaned the O-rings, check all bolts and screws around your Jacuzzi jets. Over time, these bolts and screws can loosen, which can cause leaks. To tighten them, just use a wrench or screwdriver (depending on what type of fastener it is) and tighten until it’s snug but not too tight.

You don’t want to over-tighten these fasteners because you could strip the threads or break something. Instead, ensure they’re tight enough, so there’s no play in them. If your Jacuzzi jet still leaks after following these steps, then you may need to replace the gasket or seal around the jet itself. These parts can wear out over time and need to be replaced.

Step 8: Check the Water Supply Line

If the water supply line is damaged, it will need to be replaced. First, inspect the line for any signs of wear, such as cracks or leaks. If possible, the entire line should be replaced rather than just the damaged portion. Next, ensure the new line is properly connected to the water supply and has no leaks. If your Jacuzzi does not have an easily accessible water supply line, you may need to hire a professional to replace it.

Step 9: Reconnect the Water Supply

Reconnect the water supply line to the Jacuzzi. Make sure that it is adequately tightened so that there are no leaks. Once the water supply is reconnected, please turn on the power to the Jacuzzi and test the jets to ensure they’re working properly. If no water is coming out of the jets, then there is likely a problem with the water supply line or the O-rings.

Step 10: Put Everything Back Together

Once you’ve made all the necessary repairs, it’s time to put everything back together. Start by turning the jet covers on and reconnecting the water supply line. Next, make sure that all bolts and screws are tightened properly. Once everything is back in place, turn on the power to the Jacuzzi and test the jets to ensure they’re working properly.
