I finally went to the kitchen and took a look. What is
happening is
the H&C faucets are being left on and because of the
circulator pumps
keeping the hot side pressurized whenever someone goes to a
water
fountain or flushes a toilet the hot is crossing through the
faucet
into the cold water.

Weird that a check valve is not required in this situation
or the
inspector missed it.

Thanks.
