Our ES3000 litre slimline tank has undergone a structural change.  The inlet, at the top of the tank, has now been changed to one end of the tank.  The inlet (which has a leaf strainer screwed into it) has been moved to the end of the tank where there is the one ankle height outlet. There is now a circular template at the other end of the tank at the top to be used to place a submersible pump into the tank or to use with some of the new look mains water switches. The overflow hoods will now take up to 150ml overflow.  Lead time to manufacture is now back to 3-4 weeks.  Please ring us with any enquiries.

The ES3000 is ideally suited to place against a wall of a house or granny flat to capture rainwater for use in the garden, or household applications such as toilets and laundry.  

Included with your tank purchase is a 25mm ball valve, leaf strainer (fitted) and 90mm overflow flange and mozzie stoppa. 

The inlet (fitted with a leaf strainer) is located at one end of the tank. Overflows are moulded into the tank at the top of each end (attach overflow flange/mozzie stoppa according to your requirements). 

A 25mm brass outlet is moulded into the tank at ankle height at both ends of the tank. A 25mm brass outlet is located at bucket height at one end of the tank. This allows you to attach the ball valve/ pump according to your requirements.

Outlets and overflows are sealed however can be drilled out upon request at time of order or by using a holesaw.

Joining two or more tanks together is easy with the use of flexible coupling (made to suit your required length, price on application) and an additonal 25mm ball valve ($25) to connect to a pump.
