Protect Your Water Supply

Professional Backflow Testing You Can Rely On

Backflow is a serious plumbing issue where contaminated water reverses its flow and enters the clean water supply. This can pose significant health risks and lead to costly compliance violations. To protect your family, employees, and community, municipal health codes require property owners to install and regularly test backflow prevention devices. These devices are critical for safeguarding drinking water from pollutants, chemicals, and other harmful contaminants.

At Delco Storm & Sewer Services, we provide expert backflow testing and certification for residential and commercial properties throughout Delaware County, Philadelphia, and Lansdowne. Our certified technicians have the expertise to ensure your backflow preventer is functioning correctly, keeping your water safe and your property in full compliance with all local regulations.

Safeguard Your Water

Ensure Public Health and Safety

The single most important reason for backflow testing is to protect the health of your family, customers, and community. Backflow can introduce dangerous contaminants like pesticides, chemicals, bacteria, and waste products into the public drinking water. This contamination can happen without any visible signs, making it a silent but serious threat. A properly functioning backflow preventer acts as a critical safety barrier.

Our certified testing services confirm that this barrier is working exactly as it should. By verifying that no contaminated water can flow backward into the clean water lines, we help you eliminate the risk of waterborne illnesses and ensure the water you use for drinking, cooking, and bathing is safe. This is an essential service for all properties, but especially for businesses like restaurants, medical facilities, and schools.

Avoid Fines & Shutdowns

Maintain Full Regulatory Compliance

In Pennsylvania, water authorities in jurisdictions like Philadelphia and Delaware County have strict regulations requiring annual backflow testing for most commercial properties and many residential ones. Failing to comply with these mandates can result in significant consequences, including hefty fines, service interruptions, and even business shutdowns. These regulations are not just suggestions; they are legal requirements enforced to protect the public water system.

Our service is designed to make compliance simple and stress-free. We stay up-to-date on all local codes and testing requirements, ensuring your test is performed correctly and meets all legal standards. Once your device passes inspection, we manage all the necessary paperwork and submit it directly to the appropriate municipal water department on your behalf, providing you with a complete record for your files.

Don’t risk the financial and operational penalties of non-compliance. Partnering with Delco Storm & Sewer Services ensures your property remains in good standing with local authorities year after year. We provide timely reminders for your next scheduled test so you never miss a deadline, keeping your operations running smoothly and legally.

Got Questions?

Backflow Testing FAQs

Understanding backflow prevention and testing can be confusing. To help you, we’ve compiled answers to some of the most common questions we receive from property owners in our community.

What exactly is backflow?

Backflow is the unwanted reversal of water flow from a property’s plumbing system back into the public water supply. This can occur due to changes in water pressure (back-siphonage or back-pressure) and can introduce contaminants into the clean drinking water.

Why is backflow testing required?

Testing is a legal requirement mandated by local and state health codes to protect the public water supply from contamination. It ensures that your backflow prevention device is working correctly to stop contaminated water from entering the clean water system.

How often do I need to get my backflow preventer tested?

Most municipalities, including those in Delaware County and Philadelphia, require commercial and many residential backflow prevention devices to be tested at least once per year by a certified tester.

Who is qualified to perform a backflow test?

Only a technician who is specially trained and certified in backflow prevention assembly testing is legally qualified to perform the test, complete the report, and submit it to the water authority.

What happens if my backflow device fails the test?

The technician will immediately inform you of the failure and provide a detailed explanation of the problem. We will then give you a clear quote for the necessary repairs or replacement to bring the device into compliance.
