Are you looking to increase your rainwater storage capacity? Or perhaps your limited property space cannot accommodate one large tank? You can solve your problem by linking two or more poly water tanks, which you can buy from firms such as Rapid Plas.
Here are the things you should know about connecting rainwater tanks.
Advantages of a multiple tank setup system
Linking water tanks provides expandable storage and better utilisation of available space. A multiple storage tank setup can also reduce stored water losses in the event of contamination or tank failure.
And sometimes, buying several smaller capacity tanks can be more cost-effective than purchasing one extra-huge tank.
Tank connection methods
You can connect your water tanks at either the top or the bottom. When connecting the tanks at the top, an overflow serves as the connection between tanks. When the tank that is first in a series fills, its overflow will go to the next tank, and this continues until the last tank has water.
You can opt to connect your tanks at the bottom if you want to fill and drain them at the same level. Isolation valves will help prevent emptying of all the connected tanks in case of a leak in one container.
Tanks do not have to be of similar height or size
When your tanks have the same height, you will only need a simple connection. Conversely, you may need to raise a smaller tank so its overflow can be at the same height as that of a larger tank. Also, you can take advantage of the unique topography of your property when connecting tanks of different heights.
If you property space is limited, you can decide to buy several small-sized tanks instead of a large tank you cannot easily accommodate. You may also need to buy an extra rainwater tank if you want to increase your storage capacity.
Whatever your reason for investing in more than one tank, there are ways to link them to enjoy the benefits and convenience.
