How does it work?
The Rain Director® pumps through a control unit, up to a “smart header tank” usually situated in a loft space. Inside the header tank are two level sensors, upper and lower. The system fills the header tank to 
the upper sensor then does not use the pump again until virtually all of the water is used and the lower sensor is reached. This “batch filling” process means the pump cycles 1-2 times per day, in comparison to every time a toilet is flushed with traditional systems.
Coupled with the large reduction in energy and pump wear, the Rain Director® has numerous benefits in comparison to others on the market.
- Full mains override, providing water in every eventuality: Low rainwater, pump failure or powercut.
- Smart user functionality.
- Ensures water quality by cycling water in the header tank if no activity is registered within 72 hours.
- 3 stage, electronic and physical overflow prevention system.
- Cost effective and simple installation: push fit plumbing and image based installation guide.
- Stylish and discreet control panel.
- Fully WRAS approved. International Green Apple award winner, Waterwise approved, HBR Product innovation award winner.
Easy to install
Our F-line flat tank has become a customer favourite due to its simple and cost effective install. Up to 
70% less excavation than an equivalent sized “deep dig” tank. Great for high water table areas or heavy clay when deep excavations cause unnecessary hassle and costs. All without the need for a costly concrete backfill.
Remember, these tanks are exceptionally strong: with an optional upgrade to vehicle loading shaft and steel lid for driveways etc.
