Backflow Testing Services

Backflow Testing Services

Backflow is a severe issue that can happen in nearly any home. This term refers to the act of water running in reverse and causing clean water to become contaminated. Backflow can lead to property damage and health risks if it isn’t addressed immediately. Fortunately, Baumbach Plumbing & Remodeling provides backflow testing services.

Potential Causes Of Backflow

On nearly every property, water lines must cross-connect at a certain point. When backflow occurs, wastewater, solids, and gases often get mixed with clean water. In houses, variations in water pressure can lead to backflow from bathroom or kitchen sinks, washing machines, or swimming pools. Water sources all throughout the home can thus become contaminated.

If your toilet makes a gurgling sound, this is generally an indication of negative air pressure (i.e. “suction”) buildup. In these instances, water in your bowl may likely bubble and your toilet may flush on its own.

Frequent causes of backflow include:

How To Prevent Backflow

A professional plumber can offer you recommendations for how to prevent backflow on your property, whether it’s residential or commercial. Common backflow prevention methods include:

Air Gap

An air hole is formed at one end of the water supply line to keep pressure. This solution takes time to solve backflow issues.


This refers to “double-check valves,” which have spring-loads and a shutoff function. This solution is ideal for preventing underground backflow.


An atmospheric vacuum breaker is set up at the end of your pipes to keep water pressure.


A pressure vacuum breaker regulates water pressure by utilizing a spring-loaded valve that has a shutoff function. It’s important to note that certain PVBs can experience leaks.


These are Reduced Pressure Zone Assemblies, which are highly reliable and efficient. A pressure differential relief valve, a shutoff valve, and test cocks are used to separate a shutoff valve and a pair of spring-loaded check valves with this solution.

Depending on the type of property you own, some of these solutions may be more effective than others. Also, you should ideally ensure your backflow prevention system is tested by a professional at least once a year. There are many different types of devices for preventing backflow, each of which provides a unique level of protection from this problem. Most professional plumbers are licensed and insured, which means they are extensively trained in resolving backflow and other maintenance issues.

Fixing Common Plumbing Problems

What are the signs of a plumbing emergency?

From sudden leaks and burst pipes to sewage backups and complete loss of water pressure, identifying any unexplained water pooling, foul odors, or unusual sounds warrants immediate attention.

Look out for slow drainage, unusual sounds, low water pressure, or sudden increases in your water bill.

Avoid pouring grease down drains, use drain screens, and schedule regular professional drain cleaning to prevent clogs.

Turn off the water supply, if possible. Then, contact our emergency plumbing service immediately for assistance.

Insulate exposed pipes, keep faucets dripping during freezing temperatures, and maintain indoor heat to prevent pipes from freezing and bursting.
