Why Do You Need to Drain a Swim Spa?

Draining a swim spa is part of what enables it to remain clean and hygienic. Over time, contaminants such as dirt, oils, sweat, and more can build up in the water, making it cloudy and unsightly. To keep your swim spa looking its best for years to come, you’ll have to regularly drain out all of this unwanted material.

Additionally, chlorination is used to keep the water clean and clear. However, if too much chlorine accumulates in the water, it can start to damage your swim spa’s components over time. By draining out some of the water regularly, you can ensure that there isn’t an excessive amount of chlorine built up in the tub.

Required Items

Before you start to drain your swim spa, it’s important to make sure that you have all of the necessary items. These include:

  • A hose
  • A discharge pump (which can usually be rented from a local pool supply store)
  • Several five-gallon buckets for collecting the water
  • Heavy-duty gloves to protect your hands

The Benefits of Having a Swim Spa

1. Staying in Shape

Swim spas provide a great way to stay in shape and relax after an exhausting day. Not only do they offer a low-impact workout, but their larger size also makes them ideal for entertaining family and friends. Plus, many swim spas come with built-in massage chairs and jets, so you can get the full spa experience at home!

2. Therapy

Swim spas are known for their therapeutic benefits, such as providing relief from arthritis, joint pain, and other ailments. The powerful jets in a swim spa can be used to increase circulation and reduce tension in the body, leaving you feeling refreshed and rejuvenated after every session.

Compared to traditional pools, swim spas are much more cost-effective. Not only do they require less maintenance and upkeep, but their smaller size also means that you’ll be able to save money on energy bills in the long run.

10 Ways How to Drain a Swim Spa

1. Shut Off the Power

Shut off the power to your swim spa before beginning the draining process. This is an important safety precaution to take as you don’t want any electrical shocks while draining the water. Shutting off the power will also prevent any issues with the jets or other components.

2. Connect Your Hose

Next, you’ll need to connect one end of your garden hose to a spigot on the side of your swim spa and attach it firmly. Make sure that all connections are secure before turning on the water. Connecting your hose should be done before you turn on the pump.

3. Turn on the Discharge Pump

Now, it’s time to start draining the water from your swim spa by turning on the discharge pump. The discharge pump is used to remove all of the dirty and contaminated water from the tub quickly and efficiently. Make sure that the hoses connected to the pump are properly secured, as you don’t want any water spilling out onto the floor.

4. Start Collecting Water

Once the discharge pump is running, start collecting the discharge water in five-gallon buckets for disposal. This will ensure that no one trips over it or slips on it while it’s draining. Be sure to wear heavy-duty gloves when handling the water, as it can be quite dirty.

5. Disconnect and Drain

Once all of the water has been removed, disconnect the hose from the swim spa and allow any remaining water to drain out completely. Make sure that all drains are open, as you don’t want any standing or pooled water in your swim spa.

6. Clean and Refill the Tub

Once all of the water has been removed, it’s time to clean and refill the tub. Start by wiping down the sides of the spa with a cloth and some warm, soapy water. Afterward, use a hose to begin filling up the swim spa with fresh water until it is at the desired level.

7. Balance and Treat the Water

Now that your swim spa is filled with fresh water, it’s time to balance and treat it. To do this, you’ll want to measure the pH levels of the water using a test kit and add any chemicals or treatments as necessary to make sure they are within the proper range.

8. Turn the Power Back On

Once all of the steps above have been completed, it’s time to turn the power back on and let your swim spa heat up. Make sure that all of the jets are functioning properly before you jump in. Depending on how long it has been since you drained and refilled your swim spa, it may take a few hours for it to reach the desired temperature.

9. Test and Enjoy

Once everything is running smoothly, you’ll want to test out your swim spa to make sure that everything is working properly. Afterward, all that’s left to do is enjoy your swim spa!

10. Perform Regular Maintenance

To keep your swim spa running smoothly, it’s important to remember to perform regular maintenance. This includes draining and refilling the water every few months, as well as testing and balancing the pH levels of the water on a regular basis. Doing this will ensure that your swim spa is always clean and safe for use.

Draining and filling a swim spa can be a time-consuming task, but it is necessary to ensure that your swim spa remains clean and working properly for years to come.
