This video will guide you through everything — from turning off the power to your swim spa to draining the water and cleaning the pool alternative.

Tools you'll need to drain your swim spa:

  • Sump pump
  • Garden hose
  • Shop vac
  • Microfiber cloth

Master Spas recommends draining your swim spa every six months. However, how often you use your swim spa and how many people enjoy the pool alternative can affect when you need to drain your spa.

A sign that you need to drain your spa is if you are struggling to keep the chemicals balanced or the water clear. Over time, your swim spa water can become saturated with minerals and chemicals, which can affect the performance and efficiency.

For European countries, please refer to this Water Chemistry Guide for appropriate chemical levels per BS EN 17125:2018.
