I'm totally stumped here, hoping someone can help. When we moved into our 1954-construction home about ten years ago, we had a copper re-pipe done, and also a hot-water re-circulation system installed. It's been working great, until about six months ago, when I began to notice that the water coming out of our master bathroom sink (which is the sink located farthest from our conventional storage-tank water heater) was taking a long time to get hot. Well, I figured it's gotta be the pump, right? So I bought a new one, nearly identical to the old (a Grundfos UP15-29SU) and successfully installed it. I was very proud of myself, because I know NOTHING about plumping.
Well imagine my surprise when that DID NOTHING. The water STILL takes a really long time to get hot. The old Grundfos pump was probably just fine. Something else is going on. But what in the world could it be???
Below is a pic of the heart of the system. Pump is brand-new, pump timer is old (repurposed off the original pump), water heater's from 2009:
