A backflow is generally the unwanted change in direction of water flow. On the other hand, backflow prevention is the process of safeguarding potable water from impurities through the use of a backflow preventer. So, what does a backflow preventer do?
A backflow preventer generally provides the needed security for water flow to maintain water pressure so that it flows at a regulated speed from your plumbing fixtures.
What Causes Backflow?
Water supply moving through your house should typically be a one-way flow, When it does not go the usual path, backflow happens. Your fresh water supply could be contaminated by the reversal of water flow rate and the drop of the regular water pressure.
Safeguard Your Family’s Drinking Water!
The change in direction of water leads to the sipping of damaging water from other sources connected to the fresh water structure. The contaminated water could come back to your fresh water reservoir and do some harmful consequences.
Some sources of damaging backflow water can be from other fixtures in your house like the dishwasher, toilet tanks, swimming pools, washing machine, or even your garden water fixtures like the lawn sprinkler system. Sewage flows or even the waste bins washed by the backyard hose can also carry harmful contaminants that can be forced into your water system.
How Can Backflow Preventers Help Me?
A backflow device is also called RPZ or Reduced Pressure Zone. The accessory is installed in the house plumbing diagram to protect fresh water from contaminants that may be from the reversal of water flow. Backflow devices are typically required in structures where there is a sprinkling system, fire elimination structure or a sizeable broiler.
Typically, this device stops drinking water contaminants from entering your plumbing system as foreign materials can come from pesticides or fertilizers that are sprayed on the garden. In certain circumstances where there is a fire suppression system or a boiler, water sits idle and trapped in these structures, which advances to increase of bacterial growth and buildup of mineral load from the piping structure.
What is This Used For?
The general purpose of a backflow preventer is to eliminate the harmful effects of water reversal in the water supply system. When water pressure drops, the device opens up its valves moving water out rather than allowing possible tainted water to flow back into the drinking water supply. There can even be a bigger risk of water being contaminated even with small water pressure drops in the city water.
Residential Devices Used in Montana
There are mainly two type of devices used in residential areas to prevent backflow. They are:
Hose bib – A hose bib can be helpful in preventing such problems on outdoor water faucets. A component in the appliance lets water flow in only one direction and if water pressure drops, the spring shuts down and a valve opens clearing reversed water before it gets in the fresh water supply.
Pressure vacuum breaker – These breakers are typically set up in the pipe that store water in the home sprinkler system. This device continually functions to sense pressure changes in the water supply. If there is a drop in the air pressure coming in from the raised inlet, the valve seals itself to prevent backflow.
Common Problems Encountered by Our Local Plumbers in Montana
Although backflow valves are designed to eliminate any problems with reversal in water flow, they can also have problems over time.
Fixtures found inside the house like the kitchen sink or bathroom toilets, showers and tubs usually have an S-shaped trap installed in the system. This is commonly to trap a small amount of water after flowing water goes through the drain pipes. It typically functions as a blockade against backflow. These S-shaped piping can be very vulnerable to accumulation of debris.
Toilets have a greater risk as it has a cross-connection to indoor fixture plumbing. Toilets must include certain factors to prohibit flushed water from flowing back into the water system. They can pose a problem if they bring back bacteria and sewer gas back into your home.
A garden hose is one of the immense problems as it has a cross-connection into the water system. This can be hazardous to the water system inside the house as they are commonly used for washing cars and utilized for spraying chemicals, pesticides and other harmful chemicals in the garden and lawn.
A vacuum breaker attached to the hose bib can restrict water backflow. Although internal components of the device can be damaged over time, they can also be clogged with small debris although that can be easily removed.

Backflow prevention assembly testing is also required by law at least once a year. We can do the job for your safety.
To prevent such conditions, you need to have a yearly backflow checkup to identify any possible sources of pollution or contamination. We can equip and install your water system with devices that prevent such occurrences.
We can install valves to places where fresh water and unhealthy water is connected. In as much as water flows in a single direction, the backflow sits open. If the water flow changes direction, the device stops polluted water from getting in the water supply system.
