Single 20″ Big Blue Whole House Rainwater & Mains Water Sediment Filtration System

The Single 20″ Big Blue Whole House Water Filtration System is a high-flow sediment filtration solution designed for Australian homes, rural properties, farms and commercial applications using rainwater tanks or mains water supplies.

Featuring a 20″ × 4.5″ 5-micron pleated washable sediment filter, this system helps capture dirt, sand, silt, rust and suspended particles before water reaches household plumbing, taps, showers and appliances.

Its larger 20-inch filter cartridge provides an increased filtration surface area compared with smaller 10-inch systems, making it a practical choice for properties with higher water demand.

Designed for high-flow applications, Big Blue filtration systems can accommodate flow rates of up to 150 litres per minute, depending on the system configuration, installed cartridge, water pressure and operating conditions.

Ideal for Rainwater Tank Filtration

Rainwater collected from roofs and stored in tanks can contain dust, dirt, sediment and other suspended particles.

The Single 20″ Big Blue rainwater sediment filtration system provides a practical first stage of filtration to help improve water clarity and reduce sediment entering household plumbing.

Its large washable pleated filter cartridge is particularly useful for properties with higher water consumption or where additional sediment filtration is required.

The system can also be installed before carbon filtration or UV disinfection equipment as part of a broader rainwater treatment setup.

Recommended Applications

• Whole house rainwater filtration
• Rainwater tank sediment filtration
• Mains water sediment filtration
• Rural and farm water supplies
• Commercial water pre-filtration
• High-flow sediment filtration
• Pre-filtration before UV treatment
• Off-grid properties
• Household plumbing and appliance protection

Rainwater & Mains Water Filtration

Whether your property uses stored rainwater or mains water, sediment filtration helps improve water clarity and reduce the amount of suspended material travelling through your plumbing system.

For rainwater supplies, the washable pleated filter captures suspended particles commonly found in stored tank water.

For mains water supplies, the system helps reduce dirt, rust and other sediment entering household or commercial plumbing.

The single-stage design also allows the system to be incorporated into a larger water treatment setup.

Important: This product includes a sediment cartridge only. It does not include a carbon cartridge or UV disinfection. Chlorine, taste and odour reduction would require a suitable carbon cartridge, while rainwater intended for drinking may require additional treatment depending on water quality.
