"Pro did a good job, although it was a bit of a learning curve for the pro getting the faucet's adjusted correctly. A1 Sewer sent messages and texts to keep me informed, followed up well, and the pro showed up as scheduled. I personally removed the tile facing so the pro could get into fix the leak, although this part of the project was to be done by the pro. Since I did the tile originally, I decided to take my time removing the necessary tiles. Would have been nice if the bill would have been reduced a bit since removing these tiles took me several hours and several drill bits."

FAQs for tankless water heater installation projects in Petersburg, VA

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.
