My tankless water heater was discharging water randomly. I had no idea what the issue was. But Sergio came by ASAP and helped diagnosed what could be the issue. It was determined that my water pressure regulator was broken and the water pressure was 140 psi. He replaced it with a new one the same day within an hour, and lowered the pressure to 50 psi, and no more water is discharging from my water heater anymore.Read review on Google
