"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"Top notch service!!! Our water heater went out and we needed a new one ASAP! These type of problems always happen at the worst and most inconvenient of times. We called around and no one could make it out for at least a day? some were two days! We called Water Heater SOS and explained our need for a new water heater ASAP, they explained they had a lot of calls that day but assured us they would send someone out by end of the day.. within the hour they called us back and said they were sending one of their guys right now!!! They were extremely professional, polite and worked fast and efficiently to get us a new water heater up and running by the end of the day!!! We HIGHLY recommend Water Heater SOS"

"Mr. Eric Castillo from E.C. Plumbing replace exiting Rheem tankless water heater, with a new Rinnai tankless water heater, I provided the water heater, and Mr. Castillo did the installation. Old Rheem tankless unit was removed and the Rinnai tankless was installed, a new condensation line was run, and I had a new Rinnai descaling filter installed at this time. I would highly recommend E.C. Plumbing, and I would hire Mr. Castillo again."
