All On Backflow Preventer Systems
In the event that you have in your residential plumbing systems a connection to an irrigation system, you will have a serious need for the use of the backflow preventer system. 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, 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. The clean water in the systems will be quite contaminated as a result and this is certainly a serious hazard to health. It will be well advisable for you to have installed the backflow preventers so as to help prevent the instances of such backflows. These are typically valves and they come of various kinds and they all in their carried kinds serve all varied situations. It will as well be necessary to get to know just how it is that backflows occur.
What is first necessary for us to mention is the fact that backflow is never 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. Here are some of the like scenarios that create these risks.
One case is such as 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. When such bursts get to occur in the water supply systems, they get to cause changes in the water gradients and as such these eventually get to cause the water to change its flow direction. The other cause of backflow that we will mention is where the sprinklers are so installed in a slop.
