Now that your spa is drained and clean, you’re ready to move on to the next step: removing the old gunite spa jets.

2.1 Disconnect the Power

Before you begin to drain the spa, you must first disconnect the power to prevent any accidents. Look for the circuit breaker panel and turn off the breaker for the spa. If you are unsure which breaker to turn off, you can turn off the main power switch for the house.

Warning: Do not attempt to drain the spa or remove the jets without disconnecting the power first. Failure to do so can result in electrical shock or even death.

Once the power is off, you can move on to the next step. Make sure to test the spa with a voltmeter to verify that the power is indeed off before proceeding.

2.2 Drain the Water

Now that the power is disconnected, it is time to drain the water from the spa. Locate the drain valve and attach a hose to it. Make sure the other end of the hose is in a suitable location for the water to drain out.

Open the drain valve and let the water flow out. You can speed up the process by turning on the jets, which will help to push the water out of the plumbing lines.

Once the water has drained out, use a wet/dry vacuum to remove any remaining water from the spa. Be sure to remove as much water as possible to avoid any potential damage during the jet replacement process.

After the spa is completely drained, take a moment to inspect the inside for any signs of damage or wear that may require attention before moving on to the next step.

Note: Keep in mind that the water may contain chemicals that can be harmful to the environment, so be sure to dispose of it properly.

2.3 Clean the Spa

After draining the spa, it’s a good idea to clean it before proceeding to replace the spa jets. First, remove any debris or leaves that might have accumulated in the spa. Use a bucket or a hose to remove any remaining water, then clean the spa with a mild detergent and water.

Make sure to thoroughly scrub all surfaces, including the walls and floor of the spa. Rinse the spa with clean water to remove any soap residue, and let it dry completely before moving on to the next step. This will help ensure that the new spa jets can be installed properly.

If the spa has stubborn stains or mineral buildup, you may need to use a specialized cleaner. Follow the instructions carefully, and make sure to wear gloves and protective eyewear while cleaning the spa.
