I checked with my sister who has a nearly identical system to yours in
her house. I agree that this is an ideal solution to the problem. Now
that I have the pump on X-10, I could put a controller some sort in the
guest bathroom to provide a manual, on-demand run of the pump. I would
just need to find an X-10 controller that can send an on signal followed
by an off signal after an appropriate delay. I could use Active Home to
do this sort of thing, I think. But I do not want my computer running
all the time monitoring for this.
