I live in a 26-year-old second-floor condo with a 13-year-old hot water heater.
Historically, it would take several seconds from the time that I opened the faucet for hot water that I would actually get hot water.
For the past few days, though, hot water has arrived much faster. While most people would be pleased by this, I am worried about why hot water is arriving in just a second or two.
It is the sort of behavior that I normally associate with having used hot water recently, which has not always been the case during this period of faster-than-usual hot water. Since this is a second-floor condo, I do not have direct access to most of my pipework, which is mostly copper. And I once did have a pinhole leak in the pipes, though fortunately that was just under the sink and so I found out about it quickly.
So, I'm worried that I might have a hot-water leak somewhere that I can't see.
Is there another explanation for why I might be getting hot water at the faucet faster than before?
And, any suggestions for how I might determine whether or not I do have a hot-water leak?
