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. Quite a number of the homeowners often use extensive sprinkler systems for the sake of getting their lawns and yards irrigated. In a number of cases, there is hardly a separation that is inbuilt between the irrigation systems and the water that is used for the domestic uses in the home such as that for drinking. This situation often gets the home’s plumbing units and water supplies rather exposed to the risk of backflow, the situation where you have water flowing back into your sprinklers.
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. 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. As we dig deeper, we will now see 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. Get some of these as we have mentioned below.
The first is the fact of the use of a nearby fire hydrant. The use of these will cause drastic 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. The other cause of this has been that of the mains supply for water breaking. 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.
