1) 30th floor1. Which floor in the building?
2. Do you have low water pressure only in bathroom, or throughout the apartment (kitchen, other bathroom)?
3. Did you check the main valve or water heater valve?
I actually tried calling imdaad but they said i needed to purchase a year contract as they no longer do "a la carte"services :/This happened to me. Several maintenance firms said nothing could be done and one even told me there was one hot water tank serving the whole building (at Marina Residences). Finally, imdaad came and their guy found the right boiler in the apartment, and sorted it out in ten minutes.
