Let's see here. My mommy sent me to college so that I could play with
tinfoil, and theorize about toilets! Heavy sigh!.
I think we have missed the obvious point here. This whole things boils down
to a computer dump! If you
Does flushing the toilet activate an electrical appliance such as an extract
fan or macerating system (used in remote sited toilets where small bore pipe
work is used - common equipment is a Saniflo unit - www.saniflo.com)?

(1) Fabricate an EMC story to relate the cause (Flushing toilet) to the
effect (Rebooting PC).
A major current draw from the same circuit to which
the PC is connected appears to be happening at the

Dear Customer,
In order to speculate the cause to the effect, please answer the following
question: Is the water to which your house is connected supplied via the
city water supply, or supplied via your own well pump?
Answer: I live in a rural area and have a well pump.
After careful thought
In addition to all the other suggestions, I would check the heating elements
in the water heater. Some years ago a power surge caused by a near lightning
strike damaged one of the heating elements in our water heater. One side of
the 220VAC was shorting into the water through a crack in the
Is this a joke?

Off the top of my head I guess I would have to assume that it has to do with
power delivery rather than a data line spike. A spike into one of the data
I/O would be more likely disrupt the current application and maybe cause a

I would be tempted to say that the reboot is actually an undocumented feature
in which bad data is automatically flushed from the system.
But this actually sounds like a clear case of hydraulic hammer. In typical

I know of only two reasons and one wild speculation on why flushing a toilet
would cause the computer to reboot -
1. See if they have installed an automatic flusher on their toilet and
if it is on the same circuit as the PC. If this is the case then a line

Wild stab in the dark here. The PC is grounded to the plumbing. The
Plumbing is a mixture of grounded and ungrounded parts. When the water
flowing in the plumbing from the toilet flush connects two dissimilar
grounded parts of the plumbing, one is noisy and causes the PC to reboot.
