All On Backflow Preventer Systems
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. Most of the time, there is no inbuilt separation that is there between the irrigation systems and the potable water for domestic use. This is often a scenario that often leaves the potential and room for backflow, the situation where water moves back into the sprinklers.
The one thing that can be seen that is rather obvious is that this will in most cases place the home at a risk as it will be the case that the water will be carrying lots of contaminants such as pesticides, herbicides and as well fertilizers that are used in the gardens and lawns. 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. 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. In most of the cases, the water from the municipal suppliers will flow in the normal direction as it gets into your sprinkler systems. Though you need to note the fact that there are quite a number of situations that will often heighten the risk of the reversal of the normal flow of water in these systems. Here are some of the like scenarios that create these risks.
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. Due to this, when the water is turned on back for use after the use of the hydrant, the loss of pressure that will have resulted will be a sure cause for siphoning. The other cause of the cases of backflow is such as the case of breaks in the water mains 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.
