What’s Lurking in Your Water Pipes? Deep-Clean Your Water Pipework Safely
If you rely on tank water at home, it’s easy to assume your water is safe as long as it looks and tastes fine. But beneath the surface, there’s something called biofilm that builds up inside your pipes—and it can hide harmful bacteria from regular cleaning or sanitising. That’s where the AqueousPro™ BioCleanse comes in. This professional solution removes biofilm from your entire water network—tank to tap—so your water not only looks clean but truly is safe to use.
What Is Biofilm – and Why You Should Care
Biofilm is a slimy layer made of sugars, proteins, and DNA that clings to the inside of pipes and tapware. It creates a protected environment where dangerous bacteria can hide—even if your water appears clear. Standard clean-and-rinse methods often aren’t enough to break through that slime fortress.
AqueousPro™ BioCleanse – Safe and Tested
This is not just another tank cleaner. AqueousPro™ BioCleanse is a proven professional-grade system used in homes, schools, and even council facilities. It meets Australian Drinking Water Guidelines and delivers reliable results—removing biofilm and harmful bacteria across your entire water network.
How It Works—Science Made Simple
The cleaning power comes from AqueousPro™ 50, a uniquely blended solution of hydrogen peroxide (H₂O₂) and silver ions (Ag). Here’s how it cleans deep inside your pipes:
- Oxidative Action: Hydrogen peroxide in a hyper dose (a high concentration) reacts with the biofilm’s organic matrix—breaking apart polysaccharides, proteins, and DNA—so the slime layer loses its grip.
- Silver Ion Defense: Silver ions boost the disinfecting power by attaching to bacterial cell walls, slowing metabolism and preventing regrowth after the clean.
- Breakdown & Removal: Together, the peroxide and silver penetrate deep into biofilm layers, removing them from the pipe walls and exposing hidden bacteria to destruction.
- Flush and Finish: After a several hours, the system is completely flushed so the dissolved biofilm and debris is washed to waste.
- A further application of a controlled dose may be applied to the rainwater tank as a residual dose to curb immediate build-up.
What to Expect—Step by Step

- Hyper dose injection – A trained technician uses the BioCleanse Unit to introduce a controlled hyper dose of AqueousPro™ 50 into your system.
- Confirm sanitiser is present – Each tap external and internal are opened to allow the solution into the pipework. The water tested to confirm the solution is present in the pipework, then all taps are closed.
- Contact (Withholding) time – The solution remains locked in the pipes and taps long enough to dismantle biofilm approx. 4 hours.
- Thorough flushing – All debris and dislodged biofilm are rinsed out completely.
- Post-treatment check – Your system is inspected to confirm the job is done right and you’re left with safe, clean water.
Why It Matters to Your Home
If tank water is your household’s water source—for drinking, cooking, or bathing—it’s not just about clean water, but safe water. Biofilm can ruin water quality, cause odd tastes or smells, and pose real health risks if bacteria are allowed to thrive. AqueousPro™ BioCleanse gives you the peace of mind that your water system has been professionally sanitised—from tank to tap.
