FAQs
Got Questions?
We get it! Looking after your water tank isn’t something most people think about until there’s a problem.
Here’s a quick rundown of the most common questions we’re asked about cleaning, testing, and maintenance.
If you can’t find what you’re after, just give us a call on 0800 79 74 76 or send a message using our contact form, we’re happy to help.
What is tank cleaning?
Tank cleaning removes sludge, algae, and contaminants from your water tank. We use a vacuum-filtration system that cleans the tank without draining it, meaning you keep around 95 % of your water.
How often should I clean?
We recommend a full clean every year, however if you notice a change in water taste, smell, or clarity, this may need to be done more regularly. Rural and farm tanks may need more frequent service.
Do you have to empty the tank first?
No. Our process filters and recycles your existing water, so there’s no need to empty the tank or waste stored water.
Is your method safe?
Yes, absolutely. We don’t use any harsh chemicals. The process is fully sealed and eco-friendly, safe for people, pets, livestock, and the environment.
Can you refill my tank after cleaning?
Yes. We work with local water suppliers to arrange fast top-ups after cleaning if your levels are low.
Do you clean all tank types?
We service concrete, plastic, fiberglass, and corrugated steel tanks of all sizes.
What is water testing
Water testing checks for bacteria, pH, metals, and other contaminants that can affect taste, safety, and system performance.
Our testing process tells you exactly what’s in your water, good or bad so you can fix small problems before they turn into big ones.
It’s quick, accurate, and gives you peace of mind that what’s coming out of your tap (or trough) is genuinely safe to use.
Do you offer water testing on its own?
Yes! you don’t need a full tank clean to book a test.
We can come out just to check your water quality, run lab grade tests for bacteria, pH, or metals, and send you an easy-to-read report.
It’s ideal if you’ve noticed a change in taste, smell, or clarity, or if you just want peace of mind before your next filter change.
How do I know if my tank needs cleaning?
If your water starts tasting earthy, looking cloudy, or smelling a bit off , it’s time.
Other signs include sediment in your filters, a slimy tank wall, or visible build-up at the bottom.
Even if everything looks fine, most tanks slowly collect debris, pollen, and organic matter over time.
A quick inspection or test can confirm if it’s time for a clean, and our team can sort both in one visit.
