Backflow Preventers and Systems-The Facts You Need to Know About Them

The backflow preventer systems are often necessary in a residential property especially where there is a connection in the plumbing units to an irrigation system. As is known with many homeowners, they often use extensive sprinkler systems for the need to water their lawns and yards. In a number of cases, there is hardly a separation that is inbuilt between the irrigation systems and the water that is used for the domestic uses in the home such as that for drinking. This situation often gets the home’s plumbing units and water supplies rather exposed to the risk of backflow, the situation where you have water flowing back into your sprinklers.

As a matter of fact, the home will stand exposed to lots and lots of risks as a result of this given the fact that the water will often be laden with traces of contaminants such as fertilizers, pesticides and herbicides. This will essentially get to contaminate the clean water flowing in the systems and will quite prove to be a health hazard. So as to help prevent such instances of backflow, it will be quite appropriate for you to think of installing the backflow preventers. Talking of backflow preventers, these are ordinarily preventer valves and are available of varied types and the other fact is that these all as varied as they are serve lots of different situations. As we dig deeper, we will now see just how it is that backflows occur.

The first thing that we need to mention is the fact that backflow is not a normal occurrence. In most cases, water from the suppliers, the municipal water supplier, will flow in the right direction in your sprinkler systems. However, you need to bear in mind the fact that there are a number of situations that will as well create the risk of the reversal of the normal flow of water into the systems. The following are some of the typical cases where you risk having the cases of reversal of the flow of water in your systems.

One is the case where you happen to be using a nearby fire hydrant. In such cases where these are used nearby, they often cause drastic changes in the water pressure. As a result of this, when you get to have the water turned back on after the use of the hydrant, the pressure that was so lost as a result of the use will in most cases cause siphoning of the water. One other case and cause of backflow is the event of bursts in the mains water supply. Such bursts in the mains will often cause alterations in the water gradient a case that will eventually cause the water to reverse its flow direction. Finally, we as well need to appreciate the fact that backflow will as well be caused by cases where the sprinklers are set up in a slopped area.
