How to Buy a Replacement Jet Fitting for Your Hot Tub

If your hot tub jets are not functioning properly or if you need to replace a jet fitting, this guide will help you navigate the process. Follow these steps to ensure you select the right replacement for your spa.

Step 1: Identify Your Jet Fitting Type

Before making a purchase, determine the type of jet fitting you need. Common types include:

• Directional Jets: Can be adjusted to control water flow direction.
• Rotating Jets: Feature a rotating nozzle for a massaging effect.
• Fixed Jets: Provide a steady stream of water without adjustment.

Tip:

Check your hot tub’s manual or the manufacturer’s website for specific jet types used in your model.

Step 2: Measure the Existing Jet Fitting

Accurate measurements are crucial for a proper fit. Follow these steps to measure:

1. Remove the Jet Fitting: Carefully unscrew or pull out the existing jet fitting from the spa.
2. Measure the Diameter: Use a caliper or measuring tape to determine the diameter of the fitting. Measure both the outer diameter (OD) and inner diameter (ID) if applicable.
3. Note the Thread Type: Determine if the fitting is a slip fitting (glued in place) or threaded (screws into place).

Common Measurements:

• Standard sizes are typically 1" or 1.5" in diameter, but always confirm your specific measurement.

Step 3: Check for Compatibility

Not all jet fittings are created equal. To ensure compatibility:

• Brand and Model: Identify the brand of your hot tub and check for specific part numbers or specifications.
• Material: Most jet fittings are made from PVC or ABS plastic. Ensure the material matches or is compatible with your existing fittings.

Step 4: Choose the Right Replacement Jet Fitting

With the measurements and compatibility confirmed, it’s time to select your replacement. Consider the following:

• Type of Jet: Choose the same type of jet as your original fitting for consistent performance.
• Style and Design: Some fittings come in various colors and styles to match your hot tub’s aesthetic.
• Manufacturer’s Recommendations: Whenever possible, opt for OEM (original equipment manufacturer) parts for the best fit and quality.

Step 5: Install the New Jet Fitting

Once you have your replacement fitting, it’s time to install it:

1. Turn Off Power: Ensure your hot tub is completely powered off.
2. Clean the Area: Remove any debris or old adhesive from the fitting area.
3. Install the New Fitting: Depending on your fitting type, either screw it into place or secure it with adhesive.
4. Test the Installation: Turn the power back on and run the jets to ensure proper operation.

Conclusion

Replacing a jet fitting in your hot tub doesn’t have to be difficult. By following these steps, you can select the right replacement and enjoy a rejuvenating soak in no time.
