Arrived in the lobby and asked to meet with Jose about the shower issue customers been having with the hot water Jose was not there today however met with another maintenance tech, he mentioned this has been an on going issue for the last three years since the building was built, cleaning crews during the day will use the mop sink soap dispenser and leave the hot and cold valves on for the mop sink basin This causes the hot water running to a few rooms upstairs to go like warm and barely hot, immediately upon turning the valves off the hot water is restored to the units. When the faucet is on it’s allowing cold water to mix with the hot before it makes it to the rooms above Leaving the sinks off when not in use would be the best course of action Installing check valves at the mop sinks can correct this issue even with the water on at the sinks Pricing provided is based on normal business hours, if it’s required we return after hours a second estimate will need to be provided.
