Sewar backup?
Mystery of the day. I was sitting at my desk at home when all of a sudden I
heard the toilet flush - but I was the only one home. Checked the toilet - no water. Checked the tub - evidence of backup already subsided. Flushed the commode. Flushed fine, filled fine. Went to back bathroom - same thing. Flushed that commode - all's well. There was a strong sewer gas smell in the back of the house. Also noticed water on front porch that appeared to emanate from drain cleanouts. Called city water department - nothing going on in this area. Two days ago we had a day of very heavy rains. I was also doing a load of laundry, but am pretty sure it was already done when this happened. Can anyone tell me what has happened? Should I be concerned (other than to disinfect said tubs?)? Should I take any action (like call a plumber?). TIA, Laurie -- |

My guess: The storm runoff flooded the city sewer system, causing it to backup into your (and others) sewer lateral connection. Either the sewer venting on your house is not working or (more likely) the flooding rose to a level high enough so as to block off the vent. As the water rapidly receded, the force sucked all the water out of the toilet traps (because the vent was unable to prevent the suction). Ask around the neighborhood at similar homes at the same elevation to see if anyone else experienced it. It's probably a municipal issue and not something a plumber will be able to do much about.

Jim Thanks Jim. Sounds reasonable to me...I don't understand the whole venting thing, which is fine, it just seems reasonable. I could ask a few neighbors, but while we all know each other it's not the world's most social group...plus it happened mid day while everyone else is at work... I'll go with the flow, so to speak ;-), and just see if it happens again. In the meantime, I'll go learn about sewer vents! Thanks - Laurie |
