Product Information

Full details

The Pro-Kleen Hot Tub & Whirlpool Complete System Flush is an essential maintenance solution for hot tub and spa owners looking to deep-clean internal plumbing and restore system efficiency. It is ideal for those struggling with hidden grime, body oils, and stubborn biofilm that standard sanitizers cannot reach; however, it requires a complete water change after use, making it a deep-cleaning task rather than a quick everyday fix.

Extended Product Information

FAQs

Can I use the hot tub while the flush is in the water?

No, this product is a powerful cleaning agent and the water must not be used for bathing while the treatment is circulating.

How often should I use this product?

We recommend using this flush every time you plan to drain and refill your hot tub or spa to ensure internal plumbing remains sanitized.

Will this damage my hot tub seals?

When used according to the instructions, the formula is designed to be safe for standard hot tub and whirlpool plumbing components.

Does it remove scale as well as biofilm?

The product is primarily designed for biofilm, organic grime, and oils. For heavy mineral scale, you may need a dedicated descaling product.

Is this safe for septic tanks?

When diluted during the draining process, the amount of product is generally manageable, but always check local regulations regarding spa water disposal.

Troubleshooting

Water appears cloudy after flushing

This indicates the product is working and has dislodged debris; drain the tub, wipe down the shell, and refill with fresh water.

Jets are still not performing correctly after one treatment

If the system has heavy, long-term calcification or sludge, a second application may be necessary to fully clear the blockages.

Pros and Cons

Pros

  • Targets hidden bacteria and biofilm effectively
  • Restores original water pressure and jet performance
  • Contains professional-grade bactericide for sterilization
  • Easy to use for routine deep-cleaning cycles
  • Prevents system failure caused by long-term debris buildup

Cons

  • Requires complete draining and refilling of the tub
  • Cannot be used while the tub is occupied by bathers
  • Requires careful dosing for maximum effectiveness

Setup, Compatibility & Care

To use the Pro-Kleen System Flush, ensure your hot tub or whirlpool is filled to the operational level. Add the required amount of the formula directly into the water. Turn on all jets and pumps and allow the system to circulate for at least 30 to 60 minutes to ensure full coverage of the internal plumbing. Once the cycle is complete, turn off the system and drain the hot tub completely. Rinse the shell of the tub thoroughly to remove any loosened debris before refilling with fresh water. Store the containers in a cool, dry place out of direct sunlight to maintain the potency of the bactericide agents. Always wear protective gloves when handling the concentrate.
