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.
In the kit version, collated for you by RainWaterHarvesting.co.uk, you get the tank, the Optimax filter pack and the accessories listed below.

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.
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.

DELIVERY OF RAINWATER HARVESTING SYSTEMS
We try where possible to deliver using our own vehicle but in the event of either too greater distance or a booked calendar we may have to deliver using a third party haulier. The delivery is kerbside and the offloading is the responsibility of the customer. We suggest to organise the delivery to arrive whilst you have the digger on site to assist with offload. Our shallow dig tanks can be lifted off the vehicles by hand providing there are enough bodies on site.
The systems are held in stock at our Peterborough warehouse and we normally operate on a 7-10 delivery from receipt of order.
If you have any problems to accept kerbside deliveries or access issues please contact a member of our team on 01733 405111.
