Upon arrival, I inspected a complaint of low hot water pressure. I removed the hot and cold nipples at the top of the water heater to check for blockages. Significant corrosion buildup was found on both sides, obstructing the flow. I meticulously cleaned out all corrosion and debris, ensuring the pipes were free of any restrictions. After reinstalling the piping, I tested the system thoroughly. The customer verified the performance and confirmed that the water pressure was the best it had been since they moved in.
