GrowMax Water Power Grow 500 (5-Stage Reverse Osmosis System)

What daily water production can I expect from this system?

The Power Grow 500 produces up to 500 litres of pure water daily at a rate of 20 litres per hour. However, actual production depends on your water temperature and pressure. The system performs optimally with 25°C water temperature and 5 bar pressure. Colder water temperatures around 8-9°C and lower pressure at 4 bar will reduce production rates significantly, potentially requiring 5-6 hours to fill a 25-litre container.

How effective is the filtration at removing contaminants?

The 5-stage reverse osmosis system removes up to 95% of salts, heavy metals, chloramines, nitrates, nitrites, sediments, herbicides, pesticides and volatile organic contaminants including benzene, oils and detergents. It also eliminates up to 99% of chlorine and filters sediment particles down to 5 microns. This level of purification typically reduces water EC levels from around 338ppm to approximately 24ppm.

What components are included with the system?

The complete system includes a MaxPur sediment filter, ClearGreen carbon block, 150 GPD membrane, indoor and outdoor connectors and ball valve shut-off. All necessary filters and membrane are provided so you can start using the system immediately after installation. The package also includes pressure gauges, flow restrictors and automatic shut-off valves for optimal performance monitoring.

Can this system be used for both indoor and outdoor applications?

Yes, the Power Grow 500 includes tap connections designed for both garden and indoor house use. The system weighs 5.5kg making it portable between locations. Whether you're running a greenhouse operation, indoor grow room or outdoor garden, the versatile connection options accommodate various installation requirements whilst maintaining consistent water quality across different environments.

How does this system help with hydroponic growing?

The system produces pure water with controlled EC (electro-conductivity) levels, which is crucial for hydroponic success. By removing dissolved mineral salts, the system allows growers to start with clean water and add precise nutrients as needed. This control over water quality ensures optimal plant nutrition and prevents nutrient lockout caused by excessive dissolved solids in tap water.

What maintenance is required for optimal performance?

Regular filter replacement is essential for maintaining water quality and production rates. The sediment filter and carbon block require periodic replacement depending on your water quality and usage volume. The RO membrane typically lasts longer but should be replaced when production rates decline significantly. Monitor the pressure gauges to identify when maintenance is needed.

Will this system work with my existing water pressure?

The system is designed to work with standard household water pressure, though optimal performance requires 5 bar pressure. Most UK homes have 3-4 bar pressure which will still produce pure water but at reduced rates. If you have low water pressure, consider adding a booster pump to achieve maximum production capacity and efficiency from your reverse osmosis system.

How much waste water does the system produce?

Reverse osmosis systems typically produce waste water as part of the filtration process. The ratio can be improved by managing water pressure correctly using supplementary pumps and pressure regulators. Some users report achieving a 1:1 ratio of pure water to waste water with proper pressure management, though this varies depending on your specific water conditions and system setup.
