Why do you need to drain your hot tub?

It’s just an issue of hygiene. Even though you are sanitizing the hot tub water and shocking regularly, it’s still the same water every day if you don’t drain it. Regardless of how diligent you are with water maintenance, the water will still need to be replaced.

Each time your hot tub is in use, organic pollutants are released into the water, including lotions, bodily fluid, cosmetics, etc. These pollutants and bacteria negatively impact not only the water but also the pipes.

The contaminants accumulate and become layers of biofilm, made from bacteria and fungi. The longer this biofilm attaches to the pipes, the more the pollutants end up in the water. Allow them to build up for too long, and they will obstruct water flow and reduce filter performance.
