When should one worry about a dent, then?
So, when should you be concerned about a dent?
I just got a new water heater installed. The plumbing contractor who did it was very conscientious, but also a bit rough when removing the old tank, but very careful when installing the new one. My one concern RE the new tank is that the contractor was a little evasive about the supplier. However, I did check with the manufacturing company, and there is nothing sketchy about the water heater -- it has a valid, recognized serial number.
The dent is at the top, near the hookup the release of hot water. The dent is very very shallow, but kind of broad, though not near the hook up. It looks more like a pressure dent than a trauma dent -- as if something heavy were resting on the tank for too long. This is why I am pretty sure it happened in storage or transportation.
The dent is so shallow that you only see it if light is directed a certain way, which is why it took me about a week to notice.
Considering that the tank works perfectly after a week, and the dent is so shallow, should I worry??? Oh, also, I am getting a slight weird task from my water, something a little like castor oil. Could this be a sign, or am I imagining things?
Sorry, do not mean to hijack the thread. This is related to the original question, but don't want to steer the thread too far off the original topic.
