Barry - 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 conditioner between the PC and the outlet should solve the problem. 2. If the customer lives in a rural area, they may have a boost pump to maintain the water pressure in the house. My parents have one at their place and every time it starts they have a mini brownout (they have a 100A service box!). If the PC and the boost pump share the same circuit well we can guess what will happen. A UPS is the best solution. The smallest one on the market should do the trick. 3. The wild Speculation - The house has grounding wire connected to the pipes directly and the pipes don't provide a proper ground (plastic or dry dirt). When the toilet is flushed the water makes an electrical connection through the metal pipes in the house and the cast iron drain pipe running under the house. This would generate a spike on the grounding pin of the PC and causing it to reboot. Solution - have a licensed electrical contractor upgrade the electrical system with the proper grounding technique for the geographical area.

Assuming you were one of EMC engineers, please participate the discussion and try to answer following questions: (1) Fabricate an EMC story to relate the cause (Flushing toilet) to the effect (Rebooting PC). (2) Direct the customer to verify your speculation. (3) Fix the problem. Barry Ma --------- This message is coming from the emc-pstc discussion list.
