Slimline, Underground & Bladder Rainwater Tanks
Practical Water Storage for Suburban Homes
Not every property has room for a large water tank.
We can help with residential rainwater tanks ranging from approximately 1,000 to 5,000 litres, including popular 1,500L and 3,000L slimline tanks.
Depending on your space and property requirements, options include:
Slimline Rainwater Tanks – Ideal for narrow side passages and smaller backyards.
Round Rainwater Tanks – Practical storage for properties with more room.
Underground Rainwater Tanks – Hidden water storage where site conditions allow.
Bladder Rainwater Tanks – Flexible, low-profile tanks designed for suitable spaces beneath decks, houses and raised floors.
Replacement Rainwater Tanks – Upgrading damaged, leaking or ageing tanks.
Bladder Rainwater Tanks – Under Decks & Houses
No room for a traditional rainwater tank? Make use of the space underneath your home or deck.
Also known as flexible rainwater tanks, underfloor water tanks or pillow tanks, bladder rainwater tanks provide a space-saving alternative for suitable properties.
They can be connected to appropriate rainwater pumps, filtration systems and household rainwater plumbing.
We can help assess the available clearance, access, ground conditions and plumbing requirements to determine whether an under-deck or under-house rainwater bladder tank is suitable.
Rainwater Pumps – Onga, Davey & REEFE
Pump Repairs, Replacements & Mains Backup
Rainwater pump not working? Low water pressure? Toilet not filling from your rainwater tank?
We can assist with suitable rainwater pump repairs, servicing and replacement, including systems from Onga, Davey and REEFE.
We also work with suitable rain-to-mains changeover systems, including Onga WaterSwitch, Davey RainBank and REEFE rain-to-mains controllers.
These systems can automatically switch connected fixtures to mains water when stored rainwater is unavailable.
Rainwater Filters & First-Flush Diverters
Keeping leaves, dirt and sediment out of your tank helps protect your rainwater system.
We can assist with:
First-flush diverters and leaf strainers
Rainwater tank inlet screens
Sediment filters and rainwater filtration systems
Filter replacement and maintenance
Downpipe and tank overflow connections
Filtration requirements depend on the intended use. Rainwater intended for drinking requires appropriate water quality assessment and treatment.
Underground Tanks & Backflow Prevention
Rainwater tanks connected to household plumbing must have appropriate protection to prevent contamination of the mains drinking water supply.
Below-ground rainwater tanks may require specific backflow prevention devices, including vented dual check valves, depending on the installation and applicable Sydney Water requirements.
We can help assess suitable check valves, backflow prevention and compliant rain-to-mains connections.
Rainwater Tank Maintenance & Servicing
Regular maintenance helps keep your rainwater system operating properly.
We can assist with pump checks, filter cleaning, first-flush diverter maintenance, tank plumbing inspections and investigating poor water pressure or automatic changeover problems.
A little maintenance can help avoid unexpected pump failures and unnecessary repairs.

Can you repair or replace my rainwater pump?
Yes. We can investigate suitable pump faults, low pressure and rain-to-mains changeover problems.
What happens when my rainwater tank runs empty?
A correctly installed automatic rain-to-mains system can switch connected fixtures to mains water when rainwater is unavailable.
