Couldn't be more pleased with the experience. I had a hot water heater emergency and they came when they said, quoted a fair market price, and resolved/replaced the tank in the span of a few hours. The employee was friendly, knowledgeable, and professional. Would use them again and would highly recommend.

I had a pretty emergent issue at the house I just purchased in Point. I called them during the evening of 2/23 and by 10am on 2/24 they had someone over at my house. By the end of the day on 2/25 my issue was resolved. I had a piece of broken PVC pipe stuck at the end of my service line from a bad job done by the plumbers who altered the plumbing back around the hurricane Sandy renovation project. It was causing a backup into my home. They were able to fix this without us having to dig under the road. This helped avoid getting the township involved. Jeff and the boys were a pleasure to work with. I’d highly recommend their services. Nothing felt pushed on me and I got constant updates during the job. Stay away from larger corporate companies and hire an honest business like this one.

Backflow Prevention FAQs

Backflow occurs when water flows in the opposite direction through your plumbing system, allowing contaminated water to enter your clean water supply. A properly functioning backflow prevention device helps protect your drinking water from contamination.

Testing requirements vary based on your municipality and the type of property you own. We can inspect your system and determine whether routine testing is required.

If you notice leaks around the device, failed testing results, unusual water pressure, or visible damage, your system may need professional backflow repair.

During a backflow prevention inspection, our plumbers examine the device, check its operation, look for wear or damage, and recommend any necessary testing, repairs, or replacement.

Backflow prevention devices must be properly inspected, tested, repaired, and installed to ensure they protect your drinking water and comply with local plumbing codes. Our licensed plumbers have the training and equipment to complete the job safely and correctly.
