The work was scheduled in a timely manner. Anthony was the plumber who came out. This guy is awesome. He did amazing work. My replacing of a toilet turned into a much bigger job that added time to his work. Anthony handled it professionally, politely, could not have been nicer.

We specialize in complete home remodeling — roofing, decking, kitchens, bathrooms, and more. No job is too big or too small. Quality craftsmanship, reliable service, and customer satisfaction are our top priorities.

"I don't normally leave reviews but we had such a great experience with OP Solutions we wanted to share. The entire job was top notch. We have had numerous renovations-- large and small-- over the years and this was by far the best experience. OP Solutions provided a detailed estimate and timeline from Day 1 which they stuck to. The project came in on budget and the workmanship exceeded our expectations. The communication was fantastic, sharing pictures along the way when we couldn't get to the property. They understood and executed our vision for the kitchen and bathroom perfectly but also provided their own ideas that improved upon our original plans. We are absolutely thrilled with the work and would highly recommend."

FAQs for tankless water heater installation projects in Williamstown, NJ

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
