All the Facts You Need to Know on Backflow and Preventers
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. 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.
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. 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. But anyway, let’s get to see just how backflows get to come to occur.
What is first necessary for us to mention is the fact that backflow is never a normal occurrence. Oftentimes the water from the municipal water suppliers will flow in the right direction into 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. 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. These will in a lot of the circumstances cause extreme 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. 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. The other cause of backflow that we will mention is where the sprinklers are so installed in a slop.
