What causes sewer smells from my drains?

The usual culprit is a dry P-trap, the curved pipe that holds water to block sewer gas. Basement floor drains that rarely get used dry out first. Pour a quart of water down the drain, and the odor should fade within an hour. A smell that lingers or spreads through the house points to a cracked pipe, a failed vent, or buildup inside the line. Get that checked promptly. Hydrogen sulfide in sewer gas causes headaches and nausea at higher levels.

Who's responsible for my sewer lateral, and do I need a permit to fix it?

You own the lateral, and repairs to it need a permit. PWSA maintains the public main under the street, but any root intrusion, crack, sag, or collapse in your lateral is yours to fix. Routine clog clearing needs no permit. Repairing, relining, or replacing a lateral does, and Allegheny County Health Department rules require a licensed plumber for that work. We pull the permit and handle the inspection for you. Unpermitted sewer work tends to surface during a home sale, so it's worth doing it by the book.

What should I do if several drains back up at once?

Stop running water right away and contact us . A floor drain, toilet, and tub backing up together means a main line blockage. Every flush adds sewage to the overflow. After heavy rain in neighborhoods like Lawrenceville or the South Side, the cause might be a surcharged public sewer instead of your lateral. A camera inspection sorts that out quickly. Either way, keep kids and pets clear of the water, since sewage carries bacteria.

How do I keep my drains clear between professional cleanings?

Keep grease, oil, and food scraps out of the kitchen sink. Grease hardens as it cools and coats the pipe walls. A struggling disposal pushes chunks downstream, so schedule garbage disposal repair at the first sign of trouble. Fit hair catchers on tub and shower drains. A monthly enzyme treatment, such as BioChoiceES®, breaks down organic buildup without the pipe damage chemical cleaners can cause. Top off unused basement floor drains with water every few months so the trap stays sealed.

What's the difference between drain snaking and hydro jetting?

Snaking uses a rotating cable to break through clogs, while hydro jetting uses high-pressure water to clean the inside of the pipe. For a bathroom sink clogged with hair, a snake usually does the job. Grease, soap, and mineral buildup are harder to remove, and some residue may remain after snaking. Hydro jetting clears that buildup more thoroughly, making it useful for kitchen drains and recurring blockages. Before starting drain cleaning in Pittsburgh, we check older pipes with a camera, specifically in homes built before 1950. A corroded cast iron stack sometimes needs drain repair before it's safe to jet.

Are tree roots a common cause of drain problems in Pittsburgh?

Yes. Tree roots are a common problem in older Pittsburgh neighborhoods, especially where clay sewer pipes run beneath mature trees. Roots work their way into small gaps at pipe joints and grow until water struggles to pass through. Left alone, they can crack or collapse the pipe, which can lead to sewer line repair . Early on, drain cleaning in Pittsburgh may involve hydro jetting to clear the roots. If you live in Highland Park or Squirrel Hill and have large trees nearby, consider a camera inspection every few years to check root growth.

How much does drain cleaning cost in Pittsburgh?

Your price depends on where the clog is, what's causing it, and which method clears it. You'll see that price before any work starts. A hair clog in a bathroom sink is a quicker, simpler job than a root-choked clay lateral under a Squirrel Hill sidewalk. Pipe condition also matters: an aging cast iron stack sometimes needs a camera inspection before we choose between snaking and HydroScrub® Jetting. Your plumber checks the problem in person, explains your options, and gives you a flat-rate price. That price doesn't change if the job runs long, and there's no overtime charge on nights, weekends, or holidays.

Does Pittsburgh's combined sewer system affect my home's drains?

Yes, especially in Pittsburgh's older neighborhoods, where stormwater and sewage often flow through the same pipes. During heavy rain, the system can become overwhelmed, forcing sewage back through private sewer lines and into basement floor drains. If your drains only back up during storms, this could be why. A backwater valve helps prevent sewage from flowing back into your home, but the line should be inspected first. Our Pittsburgh drain cleaning team uses camera inspections to check for blockages and determine whether the pipe can support a valve.

When should I schedule professional drain cleaning in Pittsburgh, PA?

Book drain cleaning once a slow drain stops responding to a plunger, or when you notice gurgling, sewer odors, or water pooling in a tub. Pay attention to patterns. One slow sink usually means a branch-line clog. Several clogged drains at once point to the main sewer line, and that needs attention sooner. If your floor drain backs up after storms near the Allegheny or Monongahela rivers, schedule a camera inspection even when your drains seem fine on dry days.

Professional Process for Drain Cleaning: Pittsburgh

The first step in every drain cleaning service call is a thorough video camera inspection. A waterproof, high-definition camera feeds through the pipe to identify blockages, root growth, offset joints, and corroded sections before any tool touches the line. This inspection protects you from unnecessary work and confirms whether the problem is on your private sewer lateral or in the public main downstream.
For pipes coated with soap residue, grease, or mineral scale, HydroScrub® Jetting delivers high-pressure water at up to 3,000 PSI to scour the full interior circumference of the pipe clean. Unlike drain snaking, which punches through the center of a blockage and leaves buildup on the walls, hydro jetting removes the coating that causes repeat plumbing clogs. It's the most effective method for kitchen drain cleaning when grease buildup is the primary culprit, and it works equally well for bathroom drain cleaning jobs involving hair and soap buildup.
Following hydro jetting, our professionals apply an enzyme-based cleaner to the line. These biological agents continue breaking down organic matter after the service call ends, slowing the rate at which new buildup accumulates. Enzyme-based maintenance is safe for all pipe materials, including the cast iron drain stacks found in Pittsburgh homes built before 1950, and it causes none of the corrosive damage that chemical drain cleaners can cause.

How Pittsburgh's Infrastructure and Housing Stock Affect Your Drains

Pittsburgh drains face problems you won't see in a flat, newer city. Older pipe materials, river-valley terrain, and a century-old sewer network all contribute. Our Pittsburgh drain cleaning team sees these patterns every week:

Freeze-thaw ground movement: Winter cycles across Allegheny County shift clay sewer laterals and open gaps at the joints. Tree roots find those gaps fast, which is why root intrusion is so common in Squirrel Hill, Shadyside, and Point Breeze.
Combined sewers: Many older districts send stormwater and sewage through the same pipes. Heavy rain overloads the system, and the result is a sewer backup through your basement floor drain.
Aging cast iron and clay: Homes built before the mid-1950s often have cast iron drain stacks and clay tile laterals. Cast iron rusts from the inside, leaving a rough, narrowed pipe that snags grease and paper.
Steep hillside laterals: On sloped lots in Mount Washington, Troy Hill, and Carrick, a lateral pitched too steeply lets water race ahead of solids. Those solids get stranded and build into clogs.

A backwater valve on your main sewer line is the most reliable defense against combined-sewer backups. It closes when sewage tries to flow toward your home. Before installing one, we run a camera inspection to confirm your lateral is sound enough to support it.

Pipe condition also decides how we clean. HydroScrub® Jetting scours pipe walls clean, but it's the wrong tool for a cast iron stack worn thin by corrosion. That's why every older Pittsburgh home gets a camera inspection before we choose a method.

Responsibility matters too. The Pittsburgh Water and Sewer Authority (PWSA) maintains the public main, while the lateral connecting your home to it belongs to you. Camera footage shows exactly where a problem starts. That record helps when you talk with PWSA or file a claim with your insurance carrier.
