Professional Tank Cleaning

Over time, rainwater tanks can collect sludge, sediment, leaves, and other debris that compromise your water quality. Using safe, efficient methods, we:

  • Remove sludge and contaminants from your tank.
  • Clean internal surfaces to keep your water supply healthy.
  • Check water quality so you can use it with confidence.

Regular cleaning not only improves taste and safety, but also extends the lifespan of your tank and pumps.

We clean all tank types including:

  • Corrugated Iron Tanks
  • Concrete Tanks
  • Poly Tanks
  • Above ground and in-ground tanks!

Sediment Creates Problems

Over time, sediment, dirt, and organic matter build up inside your rainwater tank. This doesn’t just affect the taste and quality of your water – it also creates the perfect environment for harmful bacteria, algae, and mosquitoes to breed.
At Old Mates Water Tank Cleaning Services, we remove this buildup to ensure your rainwater supply stays clean, fresh, and safe to drink.

Regular Tank Cleaning Protects Your Water

To maintain healthy water, we recommend a rainwater tank clean every 2 years – or sooner if you notice signs of contamination. Booking a professional tank cleaning service early helps us minimise water loss during the process and keeps your system running efficiently.

Water Filter Replacement

Your water filters play a vital role in protecting your family’s health. Replacing them regularly improves both the quality and taste of your water. Our technicians carry a wide range of replacement water filters and filter baskets, so we can service your system on the spot.
