Toilet Boiling Over

This isn't some third world country... this is good ol USA. Every time it rains hard, the sewer backs up as both drain and sewage drains share the main drain pipes. As building superintendent, I deal with this scenario a dozen times a year. This building is almost 100yrs old and the pipes are clogged and fragile. It's in an inner-city area and so the owners prefer dealing with this rather than dig up and replace the main drain pipes. I hear from other supers in the area that this is a regular occurrence. FML. Hug your super today. They deserve it. if you're wondering why I didn't rotate the video, just remind yourself what I do for a living.
