A customer reported a potential leak, but there was no visible water. I conducted a thorough inspection, utilizing advanced leak detection equipment to identify the source. Despite the absence of visible water, the equipment confirmed a leak. I traced the issue to a hidden section of the plumbing system, repaired the affected area, and ensured the system was functioning correctly. The customer was satisfied with the resolution.

Kennesaw, GA - Upon arrival, we identified a leak in the men’s restroom urinal, caused by a failed internal seal in the diaphragm cap. The Sloan Urinal Flushvalve Assembly needed replacement. We arrived with the necessary parts and removed the old valve, installing the new 1.0 gpf Zurn flush valve. After reassembly, the urinal flushed correctly without any leaks. 
Later, we assisted with a filtration system installation in an upper lab room. A leaking connection was fixed by screwing a bushing into another bushing and attaching a quick disconnect to connect a 3/4" brass fitting into a flex hose. 

Additionally, we addressed a dishwasher issue reported by Kevin. After consulting with Ken, we confirmed it was an appliance problem, and they had the contact information for the service company.

Upon arrival, I identified that the hot water supply was completely non-functional. Upon inspection, I discovered a ball valve for the water supply to the water heater was turned off. After turning it back on, I noticed the gas valve at the water heater was also off. Once the gas valve was turned on, the water heater displayed a code 11. I proceeded to clean the flame rod and igniters, but the issue persisted. I inquired with the store manager about recent maintenance work, who confirmed that the HVAC technician had been present. Upon checking the roof, I found the gas valve for the water heater was turned off. After turning it back on, the water heater resumed normal operation, restoring hot water supply. The store now enjoys a fully functional hot water system. I signed off for Harold.

Upon inspection, I identified a small crack in the filter system housing, which was causing water to spray onto the floor. I confirmed the system pressure was at 65 psi, within the normal range. I informed the store manager about the issue and suggested contacting the filter system manufacturer for a replacement. The manager, aware of the supplier, agreed to reach out for a replacement and reconnection of the lines. Additionally, I verified that the previous service provider does not handle such repairs.

Upon arrival, I discovered extensive water damage in the basement, originating from the top of the water heater. A pinhole in the 1-1/2” Galvanized Nipple connected to the water heater's outlet was spraying water onto the Blower Fan Motor, causing it to fail. I shut off the water and power supply to the water heater to prevent further damage. I contacted the homeowner to inform them of the situation. After assessing the damage, I determined that a replacement Blower Motor Assembly and possibly a Gas Valve would be needed. I picked up the necessary parts and delivered the old water heater to the store for proper disposal. The system should be fully operational once the new parts are installed.

On July 29, I conducted a comprehensive inspection and maintenance of the store's water heater system. The system was operational with no downtime, but a flume fault was recorded in the fault history. I reset the fault and found no issues with the intake or exhaust.

I removed and inspected the flame ignition rod, discovering light soot. I cleaned the ends and reassembled the rod. Additionally, I cleaned the accumulated dust on the back side of the blower fan. No other issues were found during the inspection.

I successfully addressed a lavatory drain clog by first using a plunger to attempt to dislodge the blockage. When that didn't work, I employed a drain snake to reach deeper into the pipes. After clearing the obstruction, I flushed the drain with hot water to ensure it was fully unclogged. To prevent future clogs, I also inspected the pipes for any signs of damage and applied a drain cleaner to maintain cleanliness.
