SpaPure System Cleanse | Hot Tub Plumbing Purge

• 1 x SpaPure System Cleanse (1 pint / 16 fl oz, liquid — treats up to 750 gallons)

• Cleans hidden plumbing — reaches the pipes, jets, pump, and heater you can't see
• Lifts biofilm and gunk — frees built-up contaminants so they flush out on draining
• Resets the spa — restores internal plumbing to original condition for a clean fresh fill
• Stops recurring problems — targets the hidden source of odors, foaming, and cloudy water
• Biodegradable and non-foaming — purges thoroughly without a foam mess
• Treats large spas — one 16 oz bottle treats up to 750 gallons

The formula circulates through your entire spa system and breaks the bond between accumulated contaminants and the surfaces they cling to — the biofilm, oils, and residue lining the plumbing. Once that layer is lifted into the water, you drain the spa and it all goes out with the old water, leaving the internal surfaces clean.

Two things make it work properly: heat and circulation. The product performs best in warm water (90°F or above) — performance drops in cooler water — and it needs the jets and circulation running so it can reach every surface the water touches. That's why it's a pre-drain step rather than an everyday additive.

Pro Tip: Don't be alarmed by what you see. As the purge works, the water can turn cloudy or foamy and you may see debris or scum surface — that's exactly the point. It's the hidden gunk being pulled out of your plumbing, and it's the visible proof the product is doing its job before you drain it all away.

Never mix different products together in the same bottle or pail. Add this product directly to the spa water. Use only on spas currently heated to 90°F (32°C) or above — performance decreases in cooler water.

1. With the spa jets turned off, apply the entire contents (16 fluid ounces) directly to the spa. One bottle treats up to 750 gallons.
2. Turn the spa jet motor on the highest setting for 5 minutes. If applicable, turn the spa diverters as the water circulates. For older spas that have never used this product before, run the jets for 10 minutes.
3. Allow the spa to operate normally overnight (at least 8 hours). Do not use the spa during this time.
4. Afterward, turn on the jets again as described above, then drain the spa as you normally would.
5. Clean the spa surfaces, then rinse and degrease the filters with a spa filter cleaner.
6. Refill immediately and resume normal spa startup and daily treatment.

Pro Tip: Clean your filter cartridge while the spa is empty and the purged water is gone. The biofilm you just flushed out of the plumbing collects on the filter, so pairing a System Cleanse with a filter clean (or a fresh cartridge) at the same drain means the whole system — plumbing and filter — starts the new fill genuinely clean.

SpaPure System Cleanse can be used in all spas and hot tubs, on any sanitizer system. Because it's a plumbing purge used right before draining rather than a product that stays in your water, it fits any routine regardless of how you sanitize.

It's the natural first step in your drain-and-refill process: purge with System Cleanse, drain, clean the surfaces, then refill and resume your normal startup — balancing with pH Up / pH Down and an alkalinity increaser, then re-establishing your sanitizer. Never mix it with other products in the same bottle or pail; add it directly to the spa water.
