What is a Spa Blower?

A spa blower is an essential component of a hot tub. It’s responsible for creating a soothing and relaxing experience by producing air bubbles and circulating water in the spa. The blower is a motor-driven device that powers a small fan, which blows air through the spa’s plumbing system, creating bubbles and increasing water circulation.

Spa blowers come in various sizes, shapes, and types. The most common types of blowers are the air blower and the hydro air blower. The former is a basic blower that blows air through the water, while the latter combines water and air to create a more powerful and enjoyable massage experience.

The primary function of a spa blower is to enhance the spa experience by producing air bubbles and increasing water circulation. A blower creates a powerful stream of bubbles that massages the skin and promotes relaxation, improving the overall spa experience.

Spa blowers are relatively simple devices to install and maintain. However, to keep your spa blower functioning correctly, you need to understand how it works and how to troubleshoot issues when they arise. In the following sections, we will explain how to plumb a spa blower, including the tools required, and the steps involved.

Step-by-Step Guide on How to Plumb a Spa Blower

Step 1: Turn off the power supply and remove the spa blower from its housing.

Step 2: Determine where you want to place the blower, and mark the location on the PVC pipe. Cut the pipe at the marked location using a hacksaw or pipe cutter.

Step 3: Attach the blower to the PVC pipe using the appropriate fittings and sealants. Make sure to follow the manufacturer’s instructions for the correct installation.

Step 4: Reconnect the power supply and turn on the blower to ensure it is working properly. Check for any leaks or loose connections, and make adjustments as needed.

By following these simple steps, you can easily plumb your spa blower and enjoy a relaxing and rejuvenating spa experience.

Step 1: Turn Off Power to the Spa

Safety first – before starting any electrical work, make sure to turn off power to the spa. You can turn off the power either at the main breaker or at the spa’s sub-panel.

Locate the power switch on your spa’s control panel. Depending on the model of your spa, this could be a physical switch or a button that you press. Make sure the switch is in the “off” position.

Next, locate the circuit breaker box or sub-panel for your spa. Turn off the breaker or switch that powers the spa. You can test to make sure that power is off by using a voltage meter to check for voltage at the spa’s electrical connections.

Always remember to take proper safety precautions when working with electricity. Wear insulated gloves and goggles, and never touch any electrical components with wet hands or while standing in water.

  • Step 2.1: Locate the blower motor and ensure that it is compatible with your spa’s plumbing system.

  • Step 2.2: Determine the ideal placement of the blower motor based on your spa’s plumbing layout and accessibility for maintenance.

  • Step 2.3: Ensure that the location of the blower motor is close to a power source for easy installation.

  • Step 2.4: Take measurements to ensure that there is enough space around the blower motor to connect the plumbing pipes and fittings.

Step 3: Measure and Cut the PVC Pipe

After determining the placement of the blower, measure and cut the PVC pipe to the appropriate length using a handsaw or PVC pipe cutter. Be sure to take accurate measurements and cut the pipe as straight as possible for a secure fit.

Step 4: Dry-Fit the PVC Pipe and Fittings

Before gluing the PVC pipe and fittings together, dry-fit them to make sure they fit correctly. This will give you an opportunity to make any necessary adjustments before gluing everything in place. Once you’re satisfied with the fit, mark the positions of the fittings so you’ll know where to apply the glue.

Step 5: Glue the PVC Pipe and Fittings Together

Apply PVC cement to the inside of the fittings and the outside of the pipe where they will connect. Quickly and firmly push the pieces together, holding them in place for a few seconds to allow the cement to set. Be careful not to twist the pipe or fittings as you push them together, as this can create weak spots in the joints.

Step 6: Connect the Blower and Test the System

Connect the blower to the PVC pipe using appropriate fittings and secure it in place. Turn the power back on to the spa and test the blower system to make sure it’s working properly. Check for any leaks around the joints, and make any necessary adjustments to ensure a secure and watertight fit.

Step 3: Install the Check Valve and Air Supply Tubing

Attach the check valve to the blower’s air inlet port using PVC cement.

Connect the air supply tubing to the other end of the check valve, and run the tubing to the spa’s air manifold.

Make sure to cut the tubing to the proper length and use clamps to secure the tubing to the check valve and manifold.

If needed, add a T-fitting to the air supply line to accommodate other spa equipment that requires an air supply.

Step 4: Connect the Blower to the Air Supply Tubing

Before connecting the blower, ensure that the power is still off to avoid any accidents. Then, connect the air supply tubing to the blower. Use a hose clamp to secure the tubing onto the blower’s outlet port, ensuring that it is tightly connected.

Next, connect the other end of the tubing to the check valve installed earlier. Secure the tubing onto the check valve’s barbed fitting using another hose clamp. Ensure that the tubing is tight and not kinked.

Once the air supply tubing is securely connected to the blower and the check valve, you can turn on the power to the spa to test the blower. If everything is properly installed, the blower should work correctly, providing the desired amount of air bubbles in the spa.

Common Mistakes to Avoid When Plumbing a Spa Blower

Not following manufacturer instructions: Each blower has its own set of installation and maintenance instructions. It is important to read and follow them carefully to avoid costly mistakes.

Incorrect placement: Placing the blower in the wrong location can result in poor performance, loud noise, or even damage to the unit. It is essential to determine the proper location based on the manufacturer’s recommendations and your spa’s design.

Failure to use proper fittings: Using the wrong fittings or failing to properly secure them can cause leaks and reduce the blower’s efficiency. It is crucial to use the right size and type of fittings recommended by the manufacturer.

Skipping routine maintenance: Regular maintenance, such as cleaning the blower, checking for leaks, and replacing worn parts, is crucial to keep the blower working efficiently and prolong its lifespan. Neglecting maintenance can lead to costly repairs or even require replacing the entire unit.

Top Mistakes to Avoid for Successful Spa Blower Plumbing

  • Not properly sizing the blower: It’s important to select a blower that is appropriately sized for your spa. A blower that is too small will not provide adequate air flow, while a blower that is too large may cause damage to your plumbing system.
  • Installing the blower in the wrong location: Installing the blower in the wrong location can lead to inadequate air flow, as well as potential damage to the blower itself. Make sure to consult the manufacturer’s instructions and select a suitable location for installation.
  • Not using the correct tubing: Using the wrong size or type of tubing can impede air flow and cause damage to the blower. Be sure to use the tubing recommended by the manufacturer.
  • Not properly securing the tubing: Improperly secured tubing can come loose and cause damage to the blower or the plumbing system. Make sure to securely fasten the tubing using appropriate clamps or connectors.

To avoid these mistakes, carefully read and follow the manufacturer’s instructions and seek the guidance of a professional if needed. Taking the time to properly install and maintain your spa blower can help ensure a relaxing and enjoyable spa experience.
