"Adie was a pleasure to work with, and his crew really knew what they were doing. His quote was far below quotes by other contractors (normally a warning sign), but he clearly knew his stuff and my confidence in him was well-founded. I changed several details as the project went on, and Adie was happy to work with me and make any adjustments. There were delays caused by tile suppliers, but Adie worked to find other sources, and rearranged other commitments to make sure our project was completed as soon as possible. My only constructive criticism is that the quote was not itemized (which was ok for me at the time), but that caused an underestimated cost of the glass enclosure to go unnoticed in the budget until the end of the project. We’d made many changes over the course of the project, so were not unprepared for the higher cost of the glass, but I’d have known sooner if the budget had been itemized. Overall a great experience though and I would use East Bay again in a heartbeat!"

E. Garrity Water Solutions, LLC. is a family owned and operated business. We take pride in are work and use the highest quality products. We offer 24 hour service, 365 days a year. We provide 0% financing to qualified buyers.

"Three years later we're still dealing with the fallout from Garrity's shoddy work. We hired them to install a pump and sensor system to supply water from a new dug well. They consistently cut corners and over-charged us. We have had to hire another company to fix the issues they created (for instance, the pump controller shorted for the second time last week, and each replacement has cost > $1,500)."

FAQs for tankless water heater installation projects in Hamden, CT

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.
