Backflow Prevention: Protect Your Home’s Drinking Water
Your home’s plumbing system is designed to deliver clean, safe water whenever you turn on a tap. However, under certain conditions, contaminated water can flow in the wrong direction and enter your clean water supply. This problem is known as backflow, and it can pose serious health risks if left unaddressed.
Fortunately, backflow prevention devices are designed to stop contaminated water from entering your drinking water system. Whether caused by sudden pressure changes, water main breaks, or cross-connections, backflow can usually be prevented with the proper equipment and routine maintenance.
At Thompson Family Plumbing, we help homeowners throughout Victorville, CA, protect their families with professional backflow prevention services, inspections, and installations.
What Is Backflow?
Backflow occurs when water flows in the opposite direction from its intended path. Instead of clean water flowing into your home, contaminated water from drains, irrigation systems, or sewer lines can be pulled back into your drinking water supply.
This can happen because of:
- Sudden drops in water pressure
- Water main breaks
- Fire hydrant use
- Pump failures
- Cross-connected plumbing systems
- Sewer backups
Without proper backflow prevention, contaminated water may contain bacteria, chemicals, fertilizers, pesticides, or sewage that can affect your household’s water quality.
According to the U.S. Environmental Protection Agency (EPA), protecting drinking water systems from contamination is an important part of maintaining public health.

Why Backflow Prevention Is Important
Installing a backflow prevention device helps keep contaminated water out of your home’s potable water supply.
Benefits include:
- Protecting your family’s drinking water
- Preventing waterborne illnesses
- Reducing contamination risks
- Meeting local plumbing code requirements
- Protecting public water systems
- Providing peace of mind
Even if backflow never occurs, having preventative protection is far less expensive than repairing contamination damage.
What Is a Backflow Prevention Device?
A backflow prevention device is a specialised valve installed within your plumbing system that allows water to flow in only one direction.
If water pressure suddenly changes and contaminated water attempts to flow backwards, the device automatically closes, preventing pollutants from entering your clean water supply.
Backflow preventers are commonly installed on:
- Main water service lines
- Irrigation systems
- Fire sprinkler systems
- Outdoor hose connections
- Commercial plumbing systems
Professional Plumbing Services ensure these devices are installed correctly and function properly.
How Does Backflow Prevention Work?
Several types of backflow prevention devices are available, each designed to stop reverse water flow in different ways.
Check Valves
Check valves are one of the most common forms of backflow prevention.
Inside the valve is a movable flap or disc that opens when water flows normally. If water begins flowing in the opposite direction, the flap automatically closes, creating a watertight seal.
Check valves are reliable, low-maintenance, and commonly installed on residential plumbing systems.
Air Gaps
An air gap provides one of the simplest and most effective methods of backflow prevention.
Instead of using a mechanical valve, an air gap physically separates clean water from wastewater.
Common examples include:
- Kitchen sink faucets
- Dishwasher connections
- Utility sinks
Because there’s no direct connection between clean and contaminated water, backflow cannot occur.
Vacuum Breakers
Vacuum breakers protect plumbing systems from pressure changes that could pull contaminated water backwards.
When water pressure remains normal, the internal valve stays open.
If pressure suddenly drops, the valve immediately closes, preventing reverse water flow.
Vacuum breakers are commonly installed on:
- Irrigation systems
- Garden hose connections
- Outdoor faucets
- Sprinkler systems
Do You Need Backflow Prevention?
Many homeowners are legally required to install backflow prevention devices depending on local building codes and the type of plumbing system connected to their property.
You may need one if your home has:
- An irrigation or sprinkler system
- A swimming pool with automatic filling
- A private well connected to municipal water
- Fire sprinkler systems
- Cross-connections
- Commercial plumbing equipment
Homes located near flood-prone areas or at the bottom of steep hills may also benefit from additional backflow protection.
Your local municipality can advise whether annual testing or inspections are required.
Signs Your Backflow Prevention Device Needs Attention
Like any plumbing component, backflow preventers require periodic inspection and maintenance.
Contact a plumber if you notice:
- Discoloured tap water
- Unpleasant water odours
- Reduced water pressure
- Leaking valves
- Visible corrosion
- Unusual noises near the device
Routine inspections help ensure your backflow prevention system continues protecting your drinking water.
If you suspect contaminated water, our Leak Detection Services can inspect your plumbing system for hidden issues.

- Pressure testing
- Valve inspection

What a great local family company. Had a little issue today (Saturday). Gave them a call. The lady said she would have someone here between 3 & 5. It was at 1 when I called. 3:00 on the nose Don was here. Don was very friendly and had the broken pipe fixed in no time at all. The price was more than reasonable, especially last minute on a Saturday.

Plumbing technician Dean Taylor came over last week to set up a line so I could get a dishwasher installed. I didn’t have the proper setup but he took care of it in no time! Now the installers will have no problem doing it. He was very knowledgeable and professional. I will definitely have him come back for other plumbing jobs. From start to finish everyone I spoke to was very helpful! Their customer service is outstanding!
