:(I have no hot water today. Please Help. I opened the inspection port fore of the circulating pump and there is plenty of water from the tank but its not getting to any of the fixtures in the house. Upon inspection there was a lot of build-up just inside the inspection port and cap. Is there a way to clean out the line or do I have to replace the entire water line? Is this a job for the Do-It-Yourselfer or a job for Professionals? How can I get my hot water back?
