First Flush Delta In-Ground
User Manual(Incl. GST)
Get cleaner rainwater into your tank. Between downpours, dust, leaves and animal droppings can settle on your roof. When the rain returns, the first flush of water washes them off, and your first flush diverter sets it aside to keep it out of your tank. So only the cleaner water that follows is stored. Designed for in-ground installation on sloping sites, the Delta's manifold design creates a high-capacity diversion chamber from standard 100 mm pipe, so it's easy to source and assemble. It can also turn a "wet" underground pipe system into a "dry" one.
Features and benefits
Delta manifold design
Easily divert large volumes of water with Delta's unique manifold design, which only requires you to use smaller diameter pipe.
Converts a wet system to a dry system
Installed at the lowest point of your underground pipes, it drains the water that would otherwise sit in them between downpours. No standing water underground means fresher water reaching your tank.
Control how often it drains
The Electronic Release Valve lets you control how often your first flush diverter drains, so you can fine-tune the balance between water quality and quantity.
Anti-clog valve design
The large opening on the valve reduces the chance of clogging when compared to a traditional slow release valve.
All fittings included
The First Flush Delta In-Ground comes with all fittings you need to set the system up. Just add the pipe to create the storage chamber.
Easy to size for your roof
Every 1 metre of Delta chamber holds 73L, making it simple to size for your roof catchment.
