"Nick C. helped this Disabled Veteran out with a severely clogged main septic drain, going above and beyond because he also cleared out slow flowing faucets, the shower and kitchen sink as well as cleared out toilet tank water line which was also clogged. He showed and explained to me about needing a water filtration system next to well water pump because sand and dirt is getting through, clogging water pipes. He also found the Rheem on demand water heater the previous owner installed is not powerful enough, so I'm having him come back to replace and install those."

Concrete pouring, curbs & gutters, sidewalks, driveways, patios, residential foundations, retaining walls, grinding & cutting.

"Practically begged this contractor to do my job, kept getting put off. Finally got him to show up for an estimate. A week later, when I still hadn't received the estimate, I had to call and follow up. We agreed on a price. The day he was to start, he showed up (late) and wanted over 50% of the estimate. I pointed out that the State Contractor's Licensing Board allows up to 10% of the job. Things went downhill after that. He became very confused about the job itself (though we'd been over it twice) and said he would return the following day. He never did and that was fine with me, but a colossal waste of my time. I encourage you to not waste yours and call another contractor."

FAQs for tankless water heater installation projects in Adelanto, CA

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.
