Sewage Backing Up Into Your Pittsburgh Basement: Here's What to Do

Sewage backing up into a Pittsburgh basement tends to surface at two fixtures nobody in the household has touched all week: the plain freestanding toilet standing out in the open on the cellar floor, and the laundry tub beside it. Both sit lower than anything else in the building and both connect straight onto the drain that leaves for the street, so when the line outside stops accepting what the house is sending, that is where the surplus comes back in. Unpleasant, and also useful: those two fixtures tell you where the problem sits before you have to guess.

Key Takeaways: The Two Fixtures a Pittsburgh Backup Finds First

• Contamination comes before plumbing. Anything that has come back up a drain is category three water and is treated as a health hazard from the moment it surfaces.
• Everybody upstairs has to stop using water immediately, because in a tall narrow house the people adding to the problem cannot see it.
• In a house of this age the electrical panel, the meter and the light switch are all in the cellar, so the power decision gets made from the stairs and not at the wall.
• The mark the water leaves on an uncoated foundation wall is the only record of depth you will get, and it fades as the wall dries.
• Three separate parties own the run of pipe between the cellar drain and the treatment plant, and the report goes to the middle one.
• Porous material that sewage has touched leaves the building, which on a lot reached by public steps is a route to plan before the work starts.
• Roto-Rooter handles both halves of this, opening the line and dealing with what it soaked, 24/7, 365 days a year.

Three Floors Up, Somebody Is About to Flush: Do This First

1. Get word to every floor of the house. These houses are tall and narrow, and the bathroom on the third floor has no idea what the cellar looks like. One flush from up there lands on the floor downstairs.
2. Make the power decision from the top of the stairs. The panel, the meter and the pull-chain fixture are down there with the water. If any of it is close to the wet floor, do not go down to switch anything off. Have the supply cut from outside instead.
3. Keep people and pets off that level. Cellar stairs in these houses are steep, narrow and turn at the bottom, which is a poor surface to carry anything up in a hurry.
4. Photograph the water line while the wall is still wet. On bare brick or rubble stone the mark vanishes within a day of drying, and it is the evidence of how deep this got. Note the time on the first photograph.
5. Do not rinse it anywhere. Not toward the floor drain, which is already full, and not out the coal-chute opening or the areaway toward the street. Pushing it outdoors sends it to a storm inlet and creates a second problem outdoors.
6. Say the word sewage when you call. It changes what gets dispatched, what protective equipment arrives and whether anybody brings extraction gear.

Why the Cellar Toilet and the Laundry Tub Take It First

Pittsburgh's mill and mine era built tens of thousands of small brick houses for working families, and a great many were plumbed the same way: one bathroom upstairs, and downstairs a toilet sitting in the open with no walls around it, a deep laundry tub and a floor drain. It was not an afterthought. It was the fixture you used before you came upstairs at the end of a shift, and the tub beside it was where the work clothes went.

What matters now is the geometry. Those two fixtures tie straight into the cast iron building drain at its lowest point, with almost no vertical run above them and no trap seal deep enough to hold back pressure. Everything else in the house drains into a stack that joins the same pipe further along. When the line to the street surcharges it fills from the bottom, and the bottom is that toilet and that tub.

Read it that way. If the cellar fixtures are overflowing while the kitchen sink and the upstairs bathroom drain normally, the restriction is downstream of where the stack meets the building drain, which puts it under the floor or out in the yard. If upstairs is slow too, it has backed up far enough to involve the stack. It also explains where the damage lands, since that room holds the furnace, the water heater and whatever gets stored on the floor.

Three Owners Between Your Floor Drain and the Treatment Plant

Wastewater leaving a house here changes hands twice. The lateral running out under the yard belongs to the property owner. The sewer in the street belongs to the city, borough or township you live in, and each of those runs its own collection system with its own crews and its own reporting number. Only after that does it reach the interceptors along the Allegheny, the Monongahela and the Ohio River, which belong to the regional authority treating wastewater for the city and more than eighty surrounding municipalities.

That middle owner is the one to call, and calling matters. A large share of the region is on a combined sewer, meaning one pipe carries wastewater and street runoff together, so a heavy storm can fill the line your house drains into whether or not anything is wrong with your own pipe. Municipal crews track where that happens. A report made the same day, with the time and the photographs, puts your address into that record. A report made next week is a story.

It is also the conversation where a backwater valve comes up. A valve on the building drain closes against flow arriving the wrong way and is worth pricing where the street sewer is the repeat offender, but it protects nothing if the restriction sits in your own lateral, which is why the camera work comes first.

Getting It Out of a House With No Driveway

Everything porous that sewage reached leaves the building. Cardboard, carpet and pad, upholstered furniture, particleboard shelving, insulation and the bottom of any finished wall are written off, because the contamination is inside the material rather than on it. Sealed concrete, solid wood, metal shelving and bare masonry can be cleaned, disinfected and dried in place. The furnace and the water heater get inspected, not assumed to be fine.

Then there is the part that belongs to the terrain. The city maintains hundreds of sets of public steps, and a great many hillside houses have no driveway and no place a truck can stop nearer than a street above or below the roofline. That is fine for hoses and equipment, which come down. It is not fine for a soaked sofa. Work the carry route out before anything is torn out, and say so when you book, so the right number of people arrive.

Frequently Asked Questions About Sewage in a Pittsburgh Cellar

The cellar toilet has no enclosure and no door around it. Does that make the cleanup smaller or bigger?

Smaller, generally. There is no vanity, no wall base and no flooring around it holding contamination, so what has to come out is whatever was standing nearby rather than a finished room. The trade is that nothing contained the spread either, so the affected area is wider and flatter than it would be in a finished bathroom.

Who do I report this to, the city, my borough, or the regional sewer authority?

The municipality whose street you live on, because that body owns the collection sewer your lateral connects into. The regional authority owns the interceptors and the plant, and it is not the right first call for a single address. If you are unsure which municipality you are in, the crew on site can usually tell you.

Nobody can get a truck to the door because the house is up a flight of public steps. Does that change what the crew can do?

It changes the staging, not the work. Extraction hoses and equipment reach further than most people expect. What it changes is the removal of bulk material and the time that takes, so mention it when you book rather than when the crew arrives.

The cellar has no window and the only opening is the old coal chute. Will it dry out on its own?

No. A closed masonry cellar with one small opening has very little air exchange, and masonry gives moisture back for weeks after the floor feels dry. Left alone, that room stays damp enough to grow what it needs to grow. Drying it takes equipment that moves air across the surfaces and takes the moisture out of it, monitored until the readings hold.

We want to keep the workbench and the steel shelving that were standing in it. Does saving things change what the work costs?

Hard, non-porous items can be cleaned and disinfected rather than discarded, and that is a normal part of the job. Cost varies with how much water there was, how far it spread and how much material has to be removed and dried. Roto-Rooter provides on-site estimates before any work begins, so what stays and what goes is settled with you before anybody starts carrying things up the stairs.
