We had a recirculating pump installed in our new house to provide instant
hot water in the master bathroom and the kitchen. We keep it on a timer,
shutting it off at night. The other night I ran the bath in the master bath
and after 20 minutes, all I got was tepid water. Same in the kitchen.
Another bathroom, not on the recirculation pump, had plenty of hot water.
Should I be able to get hot water in the master bathroom and kitchen when
the recirc pump is off?

You should, but it seems like the cold water is back-feeding through the pump
when it's off. Is there a check valve to prevent cold-water backflow?

Good question - I'll ask the plumber who says there is nothing wrong.

If you told your plumber what you told us, and he said, "There is
nothing wrong.", then you better find a new plumber.
