Drain, Clean, Refill: The Key to a Healthy Hot Tub

Even if your hot tub water looks clear, hidden buildup can collect in the plumbing, jets, and on surfaces. Over time, this can cause cloudy water, foam, odors, poor jet performance, and increased chemical use. That’s why a proper Drain, Clean, Refill (DCR) is essential for keeping your spa fresh and healthy.

What is a Drain, Clean, Refill (DCR)?

A DCR is the process of completely emptying your hot tub, cleaning all surfaces, and refilling it with fresh water. This removes dissolved minerals, body oils, lotions, and other residues that regular water care can’t fully address.

How often should you do it?

For most hot tubs, once a year is recommended.
Heavy use may require more frequent DCRs.
Seasonal factors like pollen or hard water can also affect timing.

What About the Water You Drain?

Before you empty your spa, it’s important to know the safe and eco-friendly ways to dispose of that water. You may even be able to reuse it for your lawn or landscaping!

Hidden Problems You Can’t See

Even when your water looks perfect, buildup inside your spa can lead to:

Biofilm & bacteria in plumbing lines
Soap and lotion residue
Organic matter

Cloudy water, foam, odors, and reduced jet performance

Solutions: Spa Purge or Hot Tub Scrub

To make your Drain, Clean, Refill easier and more effective, choose the product that fits your needs:

Cleans the internal plumbing lines
Circulates through jets to remove hidden buildup
Time: Typically takes over 24 hours to complete, including circulation, draining, and refilling
Best for a deep plumbing clean during annual maintenance

Cleans the shell and surfaces of your spa
Quick, safe, and easy to use
Time: Only a few hours from start to finish
Perfect for a fast, once-a-year deep cleaning

Note: Use either Spa Purge or Hot Tub Scrub — not both at the same time. Each product is designed for a different type of cleaning.
