Hi,
I had a plumber come and replace my two water heaters. Previous heaters were installed by builder of the home. Fairly straightforward install, did not have to change much.
Once the new heaters were in, my recirculating pump stopped working (taco 006). So plumber came out and replaced the pump (same model).
The pump replacement also was pretty much using the builder's original install, except my plumber added three new things (as can be seen on the left side of the picture below, by the left water heater)
A check valve
A hose bib
An isolation valve (with yellow handle) (to the right of the recirc pump is another isolation valve that you can't see in picture. This was put in by builder)
The strange thing is now:
Even when the new recirculating pump is off (switch to off, unit makes no noise what so ever, not even a slight hum) I still get hot water quickly to all my fixtures. Maybe 5-10 seconds even to the farthest fixture in this two story house. Pretty much no material difference from when the pump is on.
With my old recirc pump, when it was off, I had to wait a long time to get hot water (more than 45-60 seconds).
What's going on? Do I now have some sort of natural circulation going on? If so, why didn't I have it before? Is the check valve doing something? Thanks
