When a clog in the toilet and shower is an emergency
Two fixtures failing together is a strong clue that the main drain is blocked. Water has fewer exits, and it will find the lowest one in the house.
Treat it as urgent if you see any of these:
- Water or sewage rising in the shower or tub when you flush
- Gurgling from the shower when the toilet drains
- A floor drain or basement fixture bubbling or overflowing
- A sewer smell that gets stronger as water backs up
Why a toilet and shower clog together
In most homes the toilet, the tub or shower and the bathroom sink each have a small branch drain. Those branches join the main drain line, which carries everything to the street. The toilet drains through a 3 to 4 inch pipe, and a shower through a 2 inch pipe, but they meet low in the house.
A blockage in that shared run backs water into the lowest, most open fixture. That is usually the tub or shower, because its drain sits closest to the floor. A flush then pushes water into the tub instead of down the pipe.

What to do in the next ten minutes
Small steps now can limit the mess and help whoever comes next.
- 1
Stop all water use
No flushing, laundry, dishwasher or showers until the line is clear.
- 2
Try one plunge
Plunge the toilet once with a flange plunger. If other drains react, the clog is shared.
- 3
Check a lower fixture
Look in the basement or at the lowest floor drain for rising water.
- 4
Find the cleanout
Many homes have a capped pipe near the foundation or in the basement. Do not open it yourself if water is high.

Call for help
Tell the dispatcher which fixtures are involved and what you did.
What the pattern of clogs tells you
Which fixtures fail points to where the blockage sits.
| What is clogged | Where the blockage probably is | Next step |
|---|---|---|
| Only the shower | Shower trap or branch with hair and soap | Hair clip tool or a cable |
| Only the toilet | Toilet trap or closet bend | Plunger or toilet auger |
| Toilet and shower | Shared bathroom line or the main | Stop water, call for cable or camera |
| Toilet, shower and a basement drain | Main line | Call right away |
| Whole house plus yard wet spot | Main line or broken lateral | Call right away, avoid using water |
When the pattern points to a shared line, a drain cleaning visit with a cable usually clears it, and a camera can show what caused it.
What commonly blocks the shared line
The cause shapes the fix, so it is worth naming.
Tree roots
Roots enter through joints in older clay or cast iron pipe and build a net that catches paper. They return unless the pipe is repaired.
Flushed wipes and paper products
Wipes labeled flushable do not break down. They snag on rough spots and collect everything behind them.
Grease from the kitchen
Fat cools in the main and narrows the line, even if the kitchen sink is far from the bathroom.
A sagging pipe section
A low spot holds water and solids. A camera shows this as a belly, and cleaning only buys time.
Which sewer district serves your street, and who owns the pipe
Four sewer districts serve Midvale: Midvale City Public Works, Cottonwood Improvement District, Midvalley Improvement District and Sandy Suburban Improvement District. Midvale City Public Works collects wastewater for about one-third of the city. Which one handles the street main depends on where you live, so check your address before you call anyone.
The piece that runs from your house to the main is the lateral. The city says lateral maintenance and ownership typically falls to the property owner, not the municipality. That means a blockage in the lateral is yours to clear, and a blockage in the main is the district's. A cleanout with water standing in it and a fully backed up home suggests the main, which is worth reporting.
Homeowner fix or professional cleaning
A plunger helps with one fixture. It does not reach a shared line.
What you can try
- Plunge the toilet once with a flange plunger
- Use a drain tool on the shower trap for hair
- Avoid running water during the attempt
- Skip chemical cleaners on a full drain
What needs a plumber
- Two or more fixtures clogged together
- Water coming up in a tub when you flush
- A cleanout that is full
- Repeat clogs after you cleared them
- A cable or camera to find the cause
Chemical cleaner in a full drain just sits there and can splash back on skin when a plumber opens the line. Hot water and patience are safer while you wait.
When to call a pro
Call right away for any backup into a tub, a floor drain or a basement fixture. Keep kids and pets away from standing water, since sewer backups carry bacteria. We can clear the line with a cable and, if needed, send a camera through it. Our sewer line cleaning page covers the deeper jobs.
We serve Midvale and nearby towns, including Sandy, and you can see more of our coverage on the areas page. If the camera shows a broken lateral, we will explain your options before you decide.
Where this guidance comes from
Sewer district and lateral ownership facts come from Midvale City's public utilities pages, and drain work follows the International Plumbing Code (IPC).
Toilet and shower clog questions from Midvale homeowners
The sink may sit higher or drain into a different branch. The toilet and shower share a lower run, and a blockage there backs up first.
Usually not. A plunger clears the toilet trap. If the shower also backs up, the blockage is further down the line and needs a cable.
If sewage is rising in the tub or floor drain, yes. Stop using water and call. If both are only slow, you can wait a few hours, but avoid adding water.
The sewer district serving your street. Midvale has four, so ask which one covers your address. The pipe from house to main is the owner's responsibility.
Policies differ. Many cover sudden water damage but not routine clogs, and sewer backup often needs a separate endorsement. Take photos and read your policy.
Yes. Our line is answered 24/7, including nights, weekends and holidays. We book same-day appointments when available and give a clear price before work starts.
