FAQs
What size water tank do I need for my property?
The ideal tank size depends on your roof catchment area, water usage habits, and available space. We’ll help you choose the right option during the consultation.
Can I use rainwater inside my home?
Yes. With the proper filtration and pump setup, rainwater can be used for toilets, laundry, and even drinking (with appropriate treatment systems).
Do you handle both tank supply and installation?
We install tanks supplied by the customer or can assist in sourcing high-quality tanks from trusted local manufacturers.
How long does water tank installation take?
Most installations are completed in a single day, though larger systems or below-ground setups may take longer depending on site conditions.
Do I need council approval for a rainwater tank?
In most cases, small residential tanks don’t require approval. For larger or commercial systems, we’ll advise on any necessary permits.
Can you connect my tank to an existing irrigation system?
Absolutely. We can connect your tank to irrigation controllers, garden tap points, or fully automated watering systems.
Do you install water tank pumps?
Yes. We install and service pressure pumps with optional filtration and automatic switching between the tank and mains water.
What maintenance does a water tank need?
Regular checks on inlets, filters, pumps, and overflows help maintain water quality and system performance. We offer scheduled maintenance as needed.
Do you service both above-ground and underground tanks?
Yes. We install, repair, and maintain both tank types depending on your property layout and preferences.
Is rainwater safe to drink?
Rainwater can be made potable with proper filtration and disinfection. For most properties, we recommend using rainwater for toilets, laundry, and gardens unless specifically treated.
What happens if the tank overflows?
We install overflow and drainage solutions to safely redirect excess water away from your home or building foundations.
Can you upgrade my old water tank system?
Yes. We can assess your current system and recommend upgrades for better efficiency, storage, and functionality.
