FAQs

 

How much rainwater does the diverter collect?

The downpipe filters collect approximately 90% of the water that falls down the downpipe. Water coming into the downpipe falls down the outside (of the inside) of the downpipe allowing for maximum collection.

What happens when my tank is full?

The unique design of the downpipe filter means that when your tank is full, the water is pushed back along the downpipe filter and continues down the downpipe. There is no messy overflowing and no need to manually turn the diverter off when the tank is full.

How much water do I need?

This is a really difficult question to answer, how big is your garden? How often do you need to water your plants? How much rain will there be? How big is your roof? These variables will affect the answer.

How long will it take to fill my tank?

We have had some great feedback from our customers that with a decent downpour the tank will fill in a matter of hours - makes you realise how much we are losing down our stormwater systems!

What about insects?

As these are 'sealed' units, insects such as mosquitoes and flies are unable to sit in the water and lay larvae.

What do the tanks ship with?

The tanks ship with everything you need to get it up and running including a downpipe filter Speedy and a standard chrome tap (the Basic range ship with a plastic tap). You can choose a brass coloured option or upgrade to the designer chrome tap at checkout.

What if my downpipes are rectangular?

No problem, when you select your tank there is also an option to select whether your downpipes are round or rectangular. We will ship the tank with the appropriate connections.

Can I install a submersible pump?

In some of our tanks you could install a submersible pump to produce extra pressure rather than just relying off the gravity fed system. You could not install a submersible pump into the Rocky Wall or Amphora tanks as these are sealed units and there isn't access to place the pump in the bottom.

What if I don't want to install the tank myself?

We understand completely that you may not want the hassle of installing your new Designer Water Tank, that is why we are working hard to develop partnerships with local providers that are happy to help. Where possible, these will be based on set pricing, so you know upfront what the cost will be.

What are the tanks made from?

The tanks are made from 100% recycled Polyethylene (PE) plastic. They are also 100% recyclable.

Where are the tanks made?

These tanks are made in a state of the art factory in Germany. Graf own a significant share of Wilken Plastics Energy where it produces all process energy and heat in their own biogas plant. They shred, wash and dry recyclable plastics that are collected from Germany's "yellow bag" plastics collection system, among other sources (plasteurope.com/news/OTTO_Graf_t245683/ ,Aug 2020).

 

What are my options for shipping?

We have a few options to be as flexible for you as possible:

  • Collection - you are more than welcome to visit us at 1/142 Ossie James Drive, Rukuhia, Hamilton by prior arrangement - we would love to meet you!
  • Point to Point - our freight company will ship to their closest warehouse for you to collect. This is a more cost effective option than door to door delivery
  • Door to Door - our freight company will deliver directly to your door. This is probably the most convenient option for you, but will cost slightly more as our freight company needs to travel further. This option will be priced individually based on your location.
