This hotel had 2 booster pump systems and one hadn’t worked in years. Piping behind the pumps were leaking and the hotel because of leaks was having to drain the entire hotel each time they made a repair. The main valve from the city was not holding. ECWS went in and with the least amount of downtime as possible removed the booster systems, replaced the main water valve, re-piped and replaced their mixing valves and replaced the existing 4″ copper that was essentially rotting away. Installed by-passes so if they have future leaks in the hotel they would not have to drain water from the entire hotel.
Below are the before and after pictures:
