I have a commercial building with 7 toilets and 7 sinks (no showers or other connections) on a single sewer line, which runs under the cement slab building to the street. The furthest sink is about 150 feet from the middle of the street, where I presume my line connects to the main sewer.
Last night, sometime between 6:00 P.M. 8:00 A.M., and with the building empty (all closed businesses, no people in the building), all the toilets and sinks erupted with some kind of grey, gooey, soapy, greasey mess. This is not normal sewage. Very little smell, and appearantly a residue of some kind from somewhere, but it did not come from my building.
My question is: What could cause this? It seems to me it would take quite a bit of back pressure in the sewer line to cause these to all back up like this, and they backed up with force, sending this stuff flying all over the bathrooms.
The city sewer department came out and inspected their line and found nothing. I am having my line roto-rooted out just to make sure there is not a problem there.
Any ideas or comments? I am clueless about how or what happened.
