As a supplier of Roto Spa products, I often receive inquiries from customers about how to properly drain their Roto Spa. Draining a Roto Spa is an essential maintenance task that ensures the longevity and optimal performance of your hot tub. In this blog post, I'll guide you through the step-by-step process of draining a Roto Spa, share some useful tips, and also introduce you to some of our popular Roto Spa models.

Why Draining Your Roto Spa is Important

Before we dive into the draining process, let's understand why it's crucial to drain your Roto Spa regularly. Over time, water in the hot tub accumulates various contaminants such as body oils, lotions, hair, and bacteria. These contaminants can not only affect the water quality but also damage the spa's components. Draining and refilling the spa at regular intervals helps maintain clean and healthy water, prevents the growth of harmful bacteria, and extends the life of your Roto Spa.

Step-by-Step Guide to Draining a Roto Spa

Step 1: Prepare Your Equipment

Before you start draining your Roto Spa, gather the necessary equipment. You'll need a submersible pump or a sump pump, a garden hose, and a suitable drainage area. Make sure the pump you choose is rated for use with hot tubs and can handle the volume of water in your spa.

Step 2: Turn Off the Power

Safety first! Before you begin any maintenance work on your Roto Spa, turn off the power supply at the circuit breaker. This will prevent any electrical hazards while you're draining the water.

Step 3: Locate the Drain Valve

Most Roto Spas are equipped with a drain valve located at the bottom of the spa. The exact location of the drain valve may vary depending on the model of your spa. Refer to your owner's manual to find the drain valve.

Step 4: Attach the Garden Hose

Once you've located the drain valve, attach one end of the garden hose to the valve. Make sure the connection is secure to prevent any leaks. Place the other end of the hose in a suitable drainage area, such as a sewer drain or a dry well.

Step 5: Open the Drain Valve

Slowly open the drain valve to start draining the water from your Roto Spa. If the water flow is too slow, you may need to use a submersible pump to speed up the process. Place the pump in the spa and connect it to the garden hose. Turn on the pump and let it run until the water level in the spa is low enough to continue draining through the drain valve.

Step 6: Monitor the Draining Process

Keep an eye on the draining process to ensure that the water is flowing smoothly and there are no leaks. If you notice any problems, such as a clogged drain or a leaky hose, stop the draining process immediately and address the issue.

Step 7: Empty the Remaining Water

Once the water level in the spa is low enough, use a wet/dry vacuum or a sponge to remove any remaining water from the spa. This will help prevent any water from stagnating in the spa and causing damage.

Step 8: Clean the Spa

After draining the water, it's a good idea to clean the interior of your Roto Spa. Use a mild spa cleaner and a soft brush to remove any dirt, debris, or scale from the walls and floor of the spa. Rinse the spa thoroughly with clean water to remove any residue from the cleaner.

Step 9: Close the Drain Valve

Once you've finished cleaning the spa, close the drain valve tightly to prevent any water from leaking back into the spa.

Step 10: Refill the Spa

After draining and cleaning your Roto Spa, it's time to refill it with fresh water. Make sure to use a water treatment product to balance the pH and alkalinity of the water and prevent the growth of bacteria.

Tips for Draining Your Roto Spa

  • Drain your spa regularly: It's recommended to drain and refill your Roto Spa every 3 to 4 months, depending on usage.
  • Use a water treatment product: Using a water treatment product will help keep the water in your spa clean and clear and prevent the growth of bacteria.
  • Follow the manufacturer's instructions: Always refer to your owner's manual for specific instructions on draining and maintaining your Roto Spa.
  • Check for leaks: Before refilling your spa, check for any leaks in the drain valve, hoses, or pump. Repair any leaks before refilling the spa to prevent water damage.
