Super glad I found this forum. I've been having this issue for about 6 months, and am totally stumped.
We have done extensive remodeling over the past 2 years and added 2 additional bathrooms. I have a AO Smith Vertex water heater, with a dedicated recirc line.
The issue I'm having is that although all bathrooms work fine by themselves. But, if I run the bath or shower in either of the 2 new bathrooms, then the water in the sinks or other showers is cold (after 1-2 minutes of use). The temperature remains constant on the shower/tub that does have hot water, and coming out of the other locations, is cold (not even warm). Thinking it was a hot water flow issue, when testing in a sink that is getting cold water, I turned off the cold water, and the problem still persisted.
The plumber suggested that it was potentially water in the recirculation line, which doesn't make sense, as I don't have any issues with the hot water unless there is another shower/tub in use.
One thing to note, is that I feel like the recirc was installed incorrectly, as they didn't use the recirc hook-ups on the water heater, and just fed it in a loop with the hot water line. Which I'm not sure is causing this issue, but might be causing the recirc water to not be of the proper temperature.
Any ideas about what might be causing this?
I have attached an image of the water heater/recirc hookup.
Thanks!
