Rain to Main Valves
Ensure a continuous water supply with our premium range of Rain to Mains Valves. These fully automatic adjustable mechanical changeover devices are designed for pressure pump supply systems, intelligently switching from rainwater to mains water when your tank runs low, during power outages, or pump failures – giving you peace of mind and uninterrupted water flow.
How Rain to Mains Valves Work
Our range of Rain to Mains Valves are hydraulically operated devices that intelligently manage your water supply. When your rainwater tank has sufficient pressure, the valve supplies tank water to your home. When tank pressure drops due to low water levels or pump issues, the valve seamlessly switches to mains water supply, ensuring you never run out of water.

Frequently Asked Questions
Q: Do I need a special pump to use the Rain to Mains Valve?
A: Yes, you need a pressure pump with a pressure controller (either built-in or separate). The valve requires a minimum pump pressure of 300 KPa (RM1600-2) or 350 KPa (RM1500-2) to operate. Most modern rainwater harvesting pumps meet this requirement.
Q: Will I need an electrician and a plumber to install it?
A: You'll need a licensed plumber for installation to comply with AS/NZS 3500.1. No electrician is required - the valve is purely mechanical with no electrical components.
Q: What happens if there's a power outage?
A: The valve automatically switches to mains water when there's no power (since the pump can't run). When power is restored and you use water again, it automatically switches back to rainwater. Your water supply continues uninterrupted.
