The filter in the kit
Graf Optimax Pro filter included as standard We have included the best available filter – Graf’s Optimax Pro filter fits neatly inside the turret of the Carat tank. With its integrated overflow siphon and inlet calming device, we no longer need to cut holes in the turret other than those provided by Graf in the moulding.
The Optimax Pro Filter is self cleaning – water arriving across the filter mesh pushes excess debris and leaves to the overflow. The optional extra hose connector permits you to connect a hose and wash it through more thoroughly from time to time. We find the alternative Universal Filter 3 leaves the debris and leaves sitting in the filter basket so the user is obliged to open up the manhole cover of the turret, get the basket out and dispose of the leaves and debris somewhere – its a bit like a teabag!. This might be a chore too many in a busy garden, so the Optimax Pro is our preferred choice. You might lose up to 5% of the rain water but it is cleaner and removes the leaf debris away to the soakaway or drain.

What is the Rain Director?
Our multi award winning low energy system, with the popular shallow dig F-Line tank for easy and cost effective installation.
The Rain Director® has a submersible pump that pumps through a control unit, up to a “smart header tank” usually situated in a loft space. Inside the header tank is a ceramic level sensor tube. The system fills the header tank to the upper part of the tube then does not use the pump again until virtually all of the water is used and the lower part of the tube 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.
1) Full mains override, providing water in every eventuality: Low rainwater, pump failure or power cut.
2) Smart user functionality.
3) Ensures water quality by cycling water in the header tank if no activity is registered within 72 hours.
4) 3 stage, electronic and physical overflow prevention system.
5) Cost effective and simple installation: push fit plumbing and image based installation guide.
6) Stylish and discreet control panel.
7) Fully WRAS approved. International Green Apple award winner, Waterwise approved, HBR Product innovation award winner.
8) Manufactured in the UK
WRAS Approval demonstrates compliance as it is granted directly by representatives of the water suppliers. It is accepted by every water supplier in the UK. WRAS No. 2010039

High Quality Submersible Pump

HydroForce ™ Rainwater Harvesting Clean Water Pump Series 4 is a submersible pressure sensitive rainwater tank pump – electronically controlled, centrifugal roto-dynamic with no reciprocating parts. Built-in non-return valve and double dry-run protection.
Manufactured in the UK and designed for rainwater harvesting systems.
Rainwater Harvesting HDPE Pipework
External HDPE Rainwater Pipe included. It is important to identify a source of a water supply. Untreated rainwater is not for human consumption and so water companies are recommending (and in some cases requiring) that Black and Green HDPE pipe is used for piping rainwater from the tank to the point of use – eg. garden tap.
The point of use should be clearly labelled to show that rain water is the source. We include 25mm black and green hdpe pipe and labels with this kit with the option to buy further rolls of pipe.
