"Enjoying our new water treatment system. Our old one was leaking. Now we have a new stainless steel system in our basement. Our salesman, Scott, was very friendly and helpful. I would recommend this company to anyone who us interested in a water treatment system."

In 1993, Tom Raynor began taking on electrical construction and service jobs across southern New Jersey. With just one assistant and one beat-up truck, Tom crisscrossed the state, building a reputation for his small outfit as one that offered professional, hands-on service and reliable, high-quality results. By 1994, it was official—Raynor Services was born! \n \nSince then, that red pick-up has been upgraded to a fleet of ten fully stocked trucks. We are now a “one-stop shop” service company, specializing in electric, heating, cooling, and generator services. Raynor Services has never lost the spirit of professional, hands-on service that it was founded on. Family-owned and operated, we combine small-business service with big-business expertise. \n \nRaynor technicians are among the best in the industry. Each must complete a rigorous hiring process – including a background check, a drug test, and an HVAC or electrical proficiency examination.

"I needed my well water to pass NJ quality standards in order to rent out the property. I had 3 estimates by different contractors, but gave the job to preferred. Hudson, the owner, really knows the water treatment business. He did a great job, worked cleanly and efficiently, and my water passed NJ quality standards. He is also great to work with. Very courteous and professional."

"This review is solely about the installation portion of the Puronics Water Treatment System since it was just installed today. The install team arrived on time, ready to go to work. The location of my main water line was tricky to get to, but they found a great solution to tap into the line via a drop-ceiling access point. They located the Hydronex Water Conditioning Cylinder and Salt Backflush Container exactly where I wanted it. Their work was clean, tight, and very professional. The RO system was backordered, so they explained that they will return within the week to install that portion of the project. They prepped for the RO install by drilling and installing the faucet in my granite countertop. After the install, they explained the whole system to my wife and I and we were up and running with conditioned water. I can't say enough about my experience with Chuck on the initial phone call, Miles who provided the water testing and sold me the system, and Ryan who installed the system. So far, I can't envision any issues that might arise with Orbit Water Solutions since they have provided outstanding service to this point!"

"Joe is the excellent plumber! He figured out smart plumbing system for my bathroom remodel, set up stand alone faucet, hooked up jacuzzi and plumbing for the sink. Also I asked him to fix other plumbing issues around my house and I'm very satisfied with all this plumbing knowledge and workmanship. I would highly recommend Aqua Joe plumbing services"
