I'm hoping that I can figure out what's going on w/ my circulating system before opening it up. I'd like to keep experimenting to a minimum...
That said:
We've got a circulating pump on the hot water (duh!) for our faucets/etc. There are 3 return lines, all which 't' and feed into a circulating pump. This feeds back into the hot water heater. There is an electronic timer on the pump. It's worked perfectly since installation/construction about 8 years ago.
Yesterday, 2 of the 3 areas served had a HUGE drop in temp. One is lukewarm at best, one is medium warm, the final one is unaffected.
The 2 problem areas will get hot if you turn the hot water on and wait a minute or two. They appear to steadily increase in temp during this time.
The easy answer is that the pump is failing. Or is it? I'm afraid that there is a blockage in 't' where 2 of the return lines come together.
All other parts of the system are fine and nothing environmental has changed.
I do not have isolation valves for any of the return circuits, but plan to install them asap. As a result, troubleshooting is almost impossible.
Ideas?
