Arrived on site and was shown large swamp cooler on left side of building. Customer states system has been down a while with water flow issues and undersized pump. Shut system down to find pan dry with debris, belts in very poor condition coming apart, severely undersized pump incapable of supplying unit with correct water flow, and was shown leaking water supply lines going to system. This unit will need a lot of work and needs parts to operate correctly. Suggest customer have plumber redo water supply line before proceeding with work. Will provide quotes for repairs and will provide additional quote to rerun water if customer would prefer. Cannot proceed any further at this point without correctly sized commercial pump and water to system. Unit will remain down until repairs are made.
