All On Backflow Preventer Systems
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. 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. 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. 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 note the fact that there are a number of situations that will create the risk of the reversal of the normal flow of water. Get some of these as we have mentioned below.
The first is the fact of the use of 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. One other case and cause of backflow is the event of bursts in the mains water supply. These often cause alterations in the water gradients and as such the water may essentially get to flow back. 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.
