igotspurs, it says you are a plummer also. Can you tell me that if the grid goes down that over time the city sewage would start backing up into our sinks, tubs, etc. We are a bit high up where the city sewage goes but cannot really get a straight answer on this. Some say it will happen anyway, others say it will not happen. I have heard about a back flow on the pipes, but not sure if we have that on ours. Can you tell me anything about this? It would be a big help so I will know more how to prepare for this.
