Many gardeners would like to use their rainwater tank to irrigate their garden. However a problem arises when the rainwater tank runs out of water. If you are on holidays at the time the consequences for your garden could be disastrous.

The ideal solution is to install the Bottomless Rainwater Tank Attachment so that your rainwater tank never runs out of water. There are other part fill valves available but these require a plumber to install the valve inside your rainwater tank. The Bottomless Rainwater Tank Attachment is completely external to the tank and so it’s easy for anyone to install.


A hose from a mains water tap is connected to the Bottomless Rainwater Tank Attachment. A valve inside the attachment opens and closes automatically to allow mains water to partially fill the tank. Whenever the tank is almost empty, the valve opens automatically, and when the water level in the tank has risen by only 28mm, the valve closes automatically. There is always plenty of room left in the tank for rainwater.


The Bottomless Rainwater Tank Attachment includes a clear vertical tube. By looking at the water level in the tube you will always know the water level in the tank.
