How to Analyze Backflow Assemblies
By Solid City BackFlow Long Island, NY
Backflow of water happens due to the difference of pressure between source and system water. If the pressure in the water delivery system in your house or business establishment drops due to some reason toxified water from other sources may enter the potable water delivery system and thereby contaminate the water. If you have drawn an irrigation system for the garden, a boiler for heating water, pumps or sprinklers for fire safety etc you are all the more prone to developing a backflow of potable water.
It can be a major health hazard since this may lead to poisoning of drinking water with untreated or contaminated water from toilet, water heater etc. It is difficult for a common man to know that backflow is occurring and the family is consuming polluted water. This calls for periodic Backflow Testing of your water delivery system.
So if you are finding that the water you are drinking tastes different from earlier get a backflow testing done for your house water delivery system. The backflow testing will come up with the exact point of weakness in the system that is giving rise to the backflow. Thus you will be able to prevent backflow of water by attending to the problem.
Important points in backflow testing
Backflow testing is a time taking procedure, and a successful test depends a lot on other factors.
Stoppage of supply
You should know that before starting a backflow testing the water supply into the whole system needs to be shut down as all kinds of testing has to be done in a no-flow condition. The backflow testing personnel will ask for your permission to isolate the water supply connection. In case of residence this is not a problem, but hospitals, boilers, cooling services where 4-hours supply of water is prerequisite this is a challenge that the management has to accept. In such cases a well coordinated and step by step approach is needed to shut off the water supply and test for backflow.
No use of water during backflow testing
Use of water during testing will bring down the pressure inside the delivery system to near zero and this may give rise to back siphoning of other and potable water owing to unprotected cross connections. Enough storage of water must be made before personnel are called for backflow testing in commercial or residential buildings. This inconvenience can be avoided if the plumbing is done in such a way that two backflow devices are connected parallel to each other.
There are some devices that prevent backflow of water even if there is difference of pressure between the outside and the system. There are backflow preventing valves and devices generating an air gap that help prevent backflow.

What is Backflow?
A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc.
For over 30 years, Solid City has been offering backflow testing / certification in the Long Island, NY area. We offer backflow device annual testing for residences and commercial properties that have irrigation systems and wells installed.
WHAT IS BACKFLOW TESTING AND ALSO WHY DO I SHOULD TEST?
Backflow testing aids prevent water contamination
When the pressure in a water system isn’t maintained, the danger for water to stream backwards right into the water supply and also come to become infected is significantly improved. Backflow screening checks the health and safety mechanisms created to secure water purity.
The feature of a backflow avoidance gadget is to keep grimy water from swimming pools, storm drains as well as various other external water sources from flowing in reverse into clean, sanitary water or right into your residence. It also keeps any kind of water from cross-connecting with the drinking water in your house.
Backflow deterrence devices or techniques are required in many local structure and also plumbing codes. One of the most usual kinds of backflow avoidance gadgets are air gaps, which is a space in your water storage area that links to your plumbing system and a check shutoff, which stops water from moving in reverse right into your house by only permitting water to flow in one instructions.
Prevention and also Testing
To prevent backflow, the majority of water districts are required to have a backflow avoidance program as well as strategy in place, along with backflow prevention tools, where required on local plumbing in order to building codes. A lot of cities as well as counties in the United States need yearly testing of each water district by a licensed backflow testing company.
