Potential Problems With Bladder Tanks

Bladder rainwater tanks in Adelaide are far less popular than standard steel or aluminium designs. However, some people do favour them in cases where they have limited space and still want to begin harvesting rain water. There are some important things to look out for when deciding whether a rainwater bladder is the right decision for you.

A rainwater bladder is a flexible PVC case which can be installed under decks and verandahs to collect rainfall. Because of this flexibility, the first thing to note is that the structure must be placed on level ground. If the ground is sloped, as it often is beneath decks, then water is going to seek the lowest point. Instead of filling evenly and making the most of the space available to store as much water as possible, you will end up with a bladder that does not work as efficiently. Secondly, because the bladder is made from a flexible PVC rather than solid steel, you need to be extra careful not to pierce it. Anything from sticks and stones to gravel can be a threat to your bladder tank. Ideally, they will be places upon a cleared dirt base, covered by a sheet of heavy duty plastic sheeting. Keep in mind that a bladder full of many gallons of water is incredibly heavy, so any nails or sharp objects even beneath this sheet can remain a problem. The flexibility of the casing also means that they have the tendency to move slightly, a problem which is of course exacerbated if they are not on a level base. For this reason, they should be situated between two support pillars.

The biggest problem with less sophisticated bladder tanks is that they inflate and deflate throughout the seasons. Obviously, you will have to find a spot that can accommodate this level of movement. In summer, when there is not as much consistent rainfall, or in fact none at all, you can encounter a problem. As more water is removed than what is coming in, the water level and air pressure begins to decrease. Just like when the air is sucked out of a balloon, your tank can crumple and make accessing the little water that is left very difficult. Some bladder tanks have overcome this issue by including a switch that automatically switches your supply to mains when there is no rainfall. Of course, in rural or arid areas, this defeats the purpose of a tank, which is to store water precisely for those times when there is little or no natural rainfall. Alternatively, you can find some good quality pumping systems that will regulate the air pressure such that the tank will not collapse. It is safe to say that while bladders may seem like a space saver, they require far more maintenance and are more restricted in their usage than regular steel tanks. If you do opt for a bladder tank, you will want to make sure that you are choosing a reliable model.

So, is there hope for properties wanting a tank but with minimal space? A bladder is certainly not the only option for those that cannot install a regular sized tank. A range of skinny or slimline tanks can solve many of your problems. You might also want to look at an underground tank, or series of smaller cylinders. All it takes is a quick chat to a reliable professional who will be able to guide through the steps to selecting the best tank size and type for your needs.
