Backflow Prevention
Because clean water should stay clean
Backflow issues can put your clean water at risk without much warning. When a backflow preventer fails or isn’t properly maintained, contaminated water can flow back into your clean water supply. At Flocco’s Plumbing, we provide backflow prevention services designed to protect your home’s water system and keep your drinking water safe.
Owner and master plumber Joe Flocco is backflow certified, and brings the knowledge and experience needed to inspect, test, and service these critical devices correctly. If something doesn’t seem right or you’ve been told backflow protection is required, we’ll walk you through what’s needed and make sure your system is working the way it should to keep your water clean and secure.

I highly recommend him!Posted on Google Bonnie OrganskiTrustindex verifies that the original source of the review is Google. Throughout the full renovation of our kitchen and redesign of our powder room, Joe demonstrated his skill and outstanding workmanship. He guided us through the process and kept us well informed of time frames for each phase and clearly communicated tasks and decisions that we were responsible for throughout the process. I would highly recommend Joe as he has a wide range of skills and completes his projects with amazing attention to detail.Posted on Google Rigo NunezTrustindex verifies that the original source of the review is Google.

Thank you Joe!Posted on Google Steve JordanTrustindex verifies that the original source of the review is Google. We have used Flocco Plumbing on multiple occassions and would not use anyone else for any other plumbing work. Joe was awesome and completed the jobs with no issues and very fair prices. These included water heater replacement, new water lines, shut off install, outside spigot replacement, toilet repair and kitchen faucet replacement. We have been very satisfied with all the work he has done and we would not hesitate to use him for any/all future work we may have.Posted on Google Casey TrowbridgeTrustindex verifies that the original source of the review is Google. Our service from Flocco’s Plumbing was excellent! Joe was very responsive, accommodating, and was able to repair our issue timely. Super friendly, and will definitely be keeping their number saved in case we need any plumbing services again!Posted on Google Kevin KennedyTrustindex verifies that the original source of the review is Google. On time, respectful and fair. Fixed a problem the first plumber overlooked. Didn't jam us up on price either! Would use again ten fold.Posted on Google Christian MartinTrustindex verifies that the original source of the review is Google. I called Joe in a panic when our main water line burst at 7 PM on a Friday. Within 45 minutes, Joe was at our door—calm, professional, and fully equipped. He diagnosed the issue quickly, explained everything in plain English (no upselling nonsense), and had the line repaired with minimal digging in under two hours. The cleanup was impeccable, and he even followed up the next day to ensure no leaks. Fair pricing, transparent quote upfront. This is the second time we've used them (first was a tricky sewer line camera inspection), and both experiences were 10/10. If you want a local mom and pop plumber who treats your home like their own, give Joe a call. Hopefully I won’t, but when duty calls I know who will be my go to guy. Highly recommend, especially for emergencies!Posted on Google Alex ChideckelTrustindex verifies that the original source of the review is Google. Joe was very professional and I’d highly recommend him for any plumbing work. Diagnosed my tricky problem and fixed it on site leaving no mess. He Left me with tips to prevent future issues.Posted on Google Grace DiLauroTrustindex verifies that the original source of the review is Google. Great service, communicates, shows up and stand up work, thankful:)

Backflow Prevention
Frequently Asked Questions
What is backflow and why does it matter?
Backflow happens when water flows backward into the clean water supply, which can allow contaminants to enter your drinking water. A backflow prevention device is designed to stop this from happening and protect your household water.
Do all homes need backflow prevention?
Not every home requires a testable backflow device, but many do depending on the plumbing setup. Homes with irrigation systems, certain water line configurations, or specific municipal requirements are more likely to need one.
How often should a backflow device be tested?
Many water authorities require annual testing once a backflow device is installed. Testing confirms the device is working properly and helps ensure continued compliance and water safety.
What happens if a backflow preventer fails?
If a device fails testing, it may need to be repaired or replaced to keep your water supply safe. A certified plumber can explain what went wrong and recommend the proper fix to restore protection and meet local requirements.
