Whats a Vacuum Breaker?
Air gaps between possible sources of contamination and plumbing access are the most basic form of protection. Vacuum breakers in the atmosphere consist of a check valve member and an air vent normally closed when under pressure. Each hose connection to the potable water supply should be equipped with a vacuum breaker.
The principle of vacuum blowing process is based on the high pressure applied by an external device to an opening in the piping system attached to a handle or similar installation so that the pressure forces may not enter the plumbing system. Such opening in the piping system may be located inside a water supply or an oil supply.
Here are some tips to make your water line strong and reliable. It uses the vacuum to remove water from the pipe. It is interesting to know that the process of water blowing is applied to water supply and to oil pipelines, both.
What a vacuum breaker does?
Vacuum breaker comes in two forms, a portable (called the EFC for optional FEM) and a mechanical type (called the HW). When installed on a main (pump or flush valve), a vacuum breaker is simply a plastic device attached to a hole in the plumbing, usually on the outside of the house. The hole is plugged with a stopper and the outside of the house ventilates.
Even when the hole has been plugged, the vacuum breaker still functions as the rest of the pump. On the surface of the motor housing (the area where the pipe sits) is a metal cylinder that sits inside a glass cylinder, covered with a rubber gasket. When the motor shaft (the round piece that turns) turns in one direction, the cylinder turns opposite.

How Does A Vacuum Breaker Work?
Vacuum breaker pumps pressurize the air between the plumbing system and a drain pipe, then removes the vacuum created by the pressurized air using an exhaust vent to the outside of the plumbing. As a result, any contaminants in the air cannot enter the plumbing system or pipes.
Hose and Drain Pipe Vacuum Breaker Configurations
Hose and drain pipe vacuum breaker units are usually installed between plumbing connection pipes and the running water supply or sewer system. The airflow is unimpeded during normal operations, and an exhaust vent is not required. Some vacuum breaker kits contain a custom-made or custom-built engine that directly heats the water from the source to a suitable operating temperature.
Why is a vacuum breaker necessary?
Vacuum breaker pumps will prevent the draining of non-treated sewage from your sink or drain. When a vacuum breaker pump is used, water will drain normally, without any extra water going down the drain.
How much will a vacuum breaker cost me?
Vacuum breaker pumps cost roughly $70 each and up to $200 each, depending on the size and type of vacuum breaker you choose. These pumps generally last about 20 years. You may be able to find used vacuum breaker pumps at a lower price.
If you are considering installing a vacuum breaker pump, we recommend purchasing a used unit from a reputable dealer. Some well-known dealers include ABC Plumbing & Heating Supply, Ace Hardware, Closet Matters and Fissler America.
Types of vacuum breakers
There are three basic types of vacuum breaker pumps: suction breaker pumps, atmospheric breakers, and ultrasonic breakers.
Vacuum breaker pumps have to pressurize the air with their respective pressurized or attached oxygen system that will run into the drain pipe. At this point, if the oxygen is not removed by the pressurized oxygen system, it will escape up the drain pipe and possibly into the home.
Those who have not used a vacuum breaker pump have probably seen a pressurized oxygen system, which looks like a tank and contains a push button that releases the pressurized oxygen from the tank. This system may be connected to the drain and typically operates as a clean inlet, as long as there is no other air leak to create a vacuum.
Where Should You Install A Vacuum Breaker?
Installation of a vacuum breaker must be done carefully to ensure proper performance of the device, its shape, size, location and, most importantly, proper air leakage and air return. One should consider installing the device in a dry environment and not be near combustible materials or in close proximity to a potential fire hazard. It should be installed as far as possible from combustible materials including plumbing components and electrical wiring. The construction of the structure should also be considered as more than one location should be installed to avoid a design failure.
The potable water supply should be connected to every faucet or hose bibb with a vacuum breaker.
It is very important to install these devices in areas that have a high risk of airborne contamination. For instance, children’s bedrooms, guest bathrooms, rental apartments and dormitories with basement toilets should have these devices.
An airburst pressure conditioner works by spraying a mixture of cleaning fluid and air between the base of the unit and the running water. The pressure acts as a seal, keeping air out of the plumbing system and preventing contaminants from reaching the water supply.
The advantage of vacuum breakers’ overpressure and heat testing is that the machine can operate at temperatures as low as -30 to -50 degrees Celsius without damaging the appliance itself.
A vacuum breaker pump is a type of plumbing device. A vacuum breaker connects this drain pipe to the plumbing system.
Steps how to Install Vacuum Breaker
These steps explain how to install one.
1. The first step in installing a vacuum breaker is to locate the drain pipe that connects to the drainage line at the bottom of the shower.
2. As you open the drain pipe from the side of the house, place the vacuum breaker on the bottom of the drain pipe.
3. Close the drain pipe back up with the vacuum breaker on the bottom.
The only purpose of the vacuum breaker is to maintain the atmospheric vacuum between the hazardous water supply system and any source of contamination.
The vacuum breaker method is one of the reliable ways of containing hazardous contamination from the plumbing system. It is a relatively low cost method of sealing off the contaminated water supply to prevent further spread of contamination or removing it and placing it in a safe storage until it can be disposed of or recycled.
Additionally, you can also put a tap in the backyard to capture any leaks to keep the water supply isolated to that tap until the danger has passed.
