All the Facts You Need to Know on Backflow and Preventers
The backflow preventer systems are often a need more so for the residential properties that have a connection to their plumbing units the irrigation systems. Most homeowners, if not all, use the extensive sprinkler systems to get to water their lawns and yards. In a lot of the cases, you will hardly get a separation system that is inbuilt that will serve to separate the waters for irrigation and the potable one that you may use for other domestic uses such as cooking and the like. This often leads to the home’s plumbing units and water supply systems remaining rather exposed to the risk of backflow, the scenario where you have water flowing back into your sprinkler systems.
As a matter of fact, this is such a risk to the home looking at the fact that the water that flows back will quite be laced with lots of contaminants such as fertilizers, pesticides and herbicides. The clean water in the systems will be quite contaminated as a result and this is certainly a serious hazard to health. In order to help prevent these instances of backflow, you may be required to have installed the backflow preventers. Backflow preventers are by far and large systems of valves and they come of varied types each type ideal for a particular purpose and varied situations. As we dig deeper, we will now see just how it is that backflows occur.
First and foremost, you need to note the fact that backflow is not a normal occurrence by any standards. Oftentimes the water from the municipal water suppliers will flow in the right direction into 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. These will in a lot of the circumstances cause extreme changes in the water pressure. As a result of this, after the water hydrant has been used and the water is turned back on for use, the pressure lost will be a cause for siphoning back of the water into the systems. 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. Installing your sprinklers in a sloppy area will as well be one other common cause for backflow.
