5 Signs It’s Time to Clean Your Water Tank
If you rely on rainwater for your home or bach in North Auckland, keeping your water tank clean is essential for maintaining healthy, safe drinking water. Over time, sludge, leaves, bird droppings, and dead animals can contaminate your water, even if it looks clear. But how do you know when it’s time to book a water tank clean?
Here are 5 key signs it's time to schedule a professional water tank cleaning.
1. Your Water Tastes or Smells Off
If your water has a strange taste or an unpleasant odour, that’s one of the clearest signs your tank needs cleaning. Organic matter and bacteria can build up inside the tank, affecting water quality.
2. Visible Sediment or Discolouration
If your water has a brown colour or bits in it, that’s sediment build-up. Rural or coastal properties can be particularly affected by dust from earthworks or sand blowing in from the beach/dunes. A tank cleaning will keep your water clear and healthy!
N.B. Cleaning sediment from a tank will make your water filters last longer, too, saving you $$$!
3. It’s Been Over a Year Since Your Last Clean
We recommend annual cleans as a general rule, especially in rural or coastal areas or if you have heaps of trees around your home/gutters. If it’s been longer than 12 months, it’s time to get your tank professionally cleaned.
4. Heavy Rain
Winter 2025 has seen above-average rainfall in Auckland. Big storms can wash all sorts of debris into your gutters and then your tank — even with a leaf diverter in place. After a wet season, it’s smart to check your tank for sludge build-up and book a clean if needed.
Tip: If you’re struggling to see, take a photo of the inside of your tank. Often, the camera will be able to pick up the bottom even if you can’t make it out with the naked eye.
5. Low Water Pressure or Clogged Filters
Sludge or sediment inside your tank can clog filters and reduce water flow. If your water pressure drops or your filter system needs more frequent changes, the problem might be inside the tank.
