Do I have to clean the tank?

A chevron

It is recommended that you empty, clean, and refill your tank at least once a year. 

What colour choices are there?

A chevron

Tanks are available in heritage green and birch grey. 

Do I have to fit the tank to a downpipe?

A chevron

No. The tank can be used to store 200L of tap water, which should be refreshed every 12 months. It can then be connected to the downpipe in an emergency. This is a good option if you are renting.

If you choose to fill your tank with tap water, cover all the air holes with duct tape the seal the lid with gladwrap to ensure debris does not get inside. 

Do I need to secure the tank?

A chevron

There is a risk that tanks could slide in an earthquake so it is a good idea to secure them. If you secure them at the base you should also secure them higher up so they don't rotate and tip over.

Can I link more than one tank together?

A chevron

Yes. A series of water tanks can be connected. You will need to buy additional material (connecting pipes/hose) from your local hardware store. 

You can connect a food grade garden hose between the two tanks using the nylex style fittings.

What is the tank made of?

A chevron

UV-resistant, food-grade plastic. It is certified as meeting New Zealand standards for water storage. 

Are they easy to install?

A chevron

Yes, the diverter kit can be installed by most home handy people. The tank comes with installation instructions and there is a video available on the Tank Guy website. If you have any concerns, the Tank Guy recommends you seek advice from your local plumber. 

How do I clean my water tank?

A chevron

Simply empty the tank, wipe and scrub any biofilm from the inside. Rinse it out and reconnect it to your downpipe or re-fill it with water.

Are these tanks subsidised by ratepayers?

A chevron

No. WREMO negotiated a bulk order to provide the tank and fittings at this exceptionally low price (retail price of the same tank and fittings is $265). Council staff and facilities have helped to store and distribute the tanks, keeping the price low. 

What do I do if I encounter a problem with the tank I purchased?

A chevron

Any problems should be referred to The Tank Guy, phone 0508 326 8888, through their website, or send them an email
