How Do I Clean My Hot Tub’s Plumbing System?

Use a pipe cleaner or plumbing flush specifically designed for hot tubs. Run it through the system with the jets on, and follow up by draining and rinsing the tub.

Why Is It Important to Clean Your Hot Tub’s Plumbing?

Cleaning your hot tub’s plumbing system is essential for several reasons. If you neglect it, the buildup of oils, body lotions, and debris can clog the pipes and reduce the effectiveness of the filtration system. Here are some of the benefits of keeping your plumbing system clean:

• Prevents clogs: Regular cleaning helps prevent debris from clogging the plumbing, which can lead to pump strain and potential system failure.
  

• Improves water quality: Clean plumbing ensures that water flows freely, allowing your filtration system to work efficiently and keep the water clean.
  

• Reduces odors: Debris and organic matter in the plumbing can create unpleasant smells in the water. Cleaning the plumbing removes the buildup, preventing any unwanted odors.
  

• Extends lifespan of equipment: Maintaining a clean plumbing system reduces the wear and tear on your hot tub’s pump and filter, extending their lifespan and reducing the need for costly repairs.
  

By taking a few steps to regularly clean your hot tub’s plumbing, you can ensure a longer-lasting and more efficient hot tub.

How to Clean Your Hot Tub’s Plumbing System

Cleaning the plumbing system of your hot tub is not a complicated process, but it does require the right steps and tools to get the job done effectively. Here’s a step-by-step guide to cleaning your hot tub’s plumbing system.

Turn Off the Hot Tub and Disconnect Power

Before you begin cleaning your hot tub’s plumbing, it’s important to turn off the power to the tub for safety reasons.

• Switch off the power: Use the control panel to turn off the power to the hot tub. This prevents any accidents while working on the plumbing.
  

• Disconnect the power supply: For added safety, you can unplug the hot tub or switch off the circuit breaker that powers the hot tub.
  

Turning off the power ensures that you won’t accidentally turn on the hot tub while cleaning the plumbing system.

Drain the Hot Tub

Next, you’ll need to drain the hot tub to allow access to the plumbing system and to clean the pipes effectively.

• Use the drain valve: Locate the drain valve at the bottom of your hot tub and open it to begin draining the water.
  

• Empty completely: Make sure to drain all the water from the hot tub, including any water in the pipes. This step is important for cleaning the plumbing properly.
  

Once the water is drained, you’ll be able to access the plumbing system for cleaning.

Use a Hot Tub Plumbing Cleaner

A specialized hot tub plumbing cleaner can help break down the oils, lotions, and debris that accumulate in the pipes. These cleaners are specifically designed to clean the plumbing without damaging the hot tub components.

• Choose a quality cleaner: Look for a plumbing cleaner that is safe for use in hot tubs and spas. Many cleaners are available at pool and spa supply stores or online.
  

• Follow the instructions: Each cleaner will have its own set of instructions. Typically, you’ll add the cleaner directly to the water and circulate it through the plumbing system.
  

• Let it sit: Allow the cleaner to circulate through the plumbing for the recommended amount of time. This will help break down buildup and ensure a thorough clean.
  

Using a specialized cleaner will help ensure that all contaminants are removed from the plumbing system.

Circulate the Cleaner Through the System

Once you’ve added the plumbing cleaner, it’s time to circulate it through the hot tub’s plumbing system.

• Turn on the pump: Turn the pump on and allow the cleaner to circulate throughout the system. You may need to run the pump for about 15–20 minutes to ensure the cleaner reaches all parts of the plumbing.
  

• Let it sit: After circulating, turn off the pump and let the cleaner sit for the recommended time (usually 30 minutes to an hour) to allow it to break down the buildup.
  

Circulating the cleaner ensures that it reaches all the pipes and jets in your hot tub, thoroughly cleaning the entire plumbing system.

Flush the System with Fresh Water

After the cleaning solution has had enough time to work, it’s time to flush the system with fresh water to remove the cleaner and any debris that has been dislodged.

• Turn the pump on again: Run the pump again to circulate fresh water through the system, flushing out any remaining cleaning solution and debris.
  

• Repeat if necessary: If the water still looks cloudy or if there’s visible debris, you may need to repeat the cleaning process until the system is completely clear.
  

Flushing the system ensures that all the cleaner and debris are removed, leaving the pipes clean and free of buildup.

Refill the Hot Tub and Test the Water

Once the plumbing system is clean, it’s time to refill the hot tub with fresh water.

• Add fresh water: Close the drain valve and refill the hot tub with fresh water. Ensure the water level is appropriate before turning the hot tub back on.
  

• Test the water: After refilling the hot tub, it’s important to test the water’s chemical balance. Make sure the pH, alkalinity, and sanitizer levels are all within the proper ranges before using the tub.
  

Testing the water ensures that the chemical balance is correct and that the water is safe for use.

Regular Maintenance and Cleaning

To keep your hot tub’s plumbing system running efficiently, regular maintenance is key.

• Clean every 3 to 4 months: Depending on the usage, clean your hot tub’s plumbing system every 3–4 months to keep it in top shape. Heavy usage may require more frequent cleaning.
  

• Use a weekly cleaner: You can also add a small amount of plumbing cleaner to your hot tub every week to help prevent buildup from accumulating.
  

• Check the filters regularly: Clean or replace the hot tub filters as recommended to ensure proper water circulation and filtration.
  

By incorporating regular cleaning and maintenance into your hot tub routine, you’ll ensure that the plumbing system stays free of buildup and functions smoothly.

Additional Tips for Plumbing Maintenance

• Avoid using harsh chemicals: Be mindful of the chemicals you use in your hot tub. Some cleaners and additives may cause excessive buildup in your plumbing. Stick to products that are designed for hot tub plumbing.
  

• Check the jets: Regularly inspect the jets in your hot tub for any signs of clogging or buildup. Clean the jets as needed to maintain a steady flow of water.

• Keep the tub covered: Always use a well-fitting cover when your hot tub is not in use. This prevents debris from entering the system and reduces the amount of work needed to keep the plumbing clean.
