If the bowl is about to overflow
Do not flush again. Take the lid off the tank, push the flapper down to stop water entering the bowl, or turn the shutoff valve behind the toilet clockwise. Put towels around the base.
If water is already spilling, lay down towels and keep it from reaching other rooms. Then work through the steps below.
Plunge the right way
A flange plunger, which has a rubber lip that fits the drain opening, works much better than a flat cup plunger. Make sure there is enough water in the bowl to cover the plunger head, and add some if there is not. Seat the plunger and push down gently first to push out the air.
Then plunge firmly in and out for about twenty seconds, keeping the seal. Many clogs release with a gurgle. If the water starts to drop, flush once to test. If it rises again, stop and try another method.
Other things to try
Use these in order, and stop if the problem changes.
- Pour a squirt of dish soap into the bowl and then a bucket of hot, not boiling, water from waist height.
- Use a closet auger, a short toilet snake with a curved end that protects the porcelain.
- Check whether tub, shower, and sink drains are slow, since that points beyond the toilet.
- Avoid chemical drain cleaners in a toilet, because they can splash and damage the finish and fittings.
- If you flushed something solid, such as a toy, stop and call a plumber.
Simple clog or main line problem?
Where else the water shows up tells you.
| What you notice | Likely location | Next step |
|---|---|---|
| Only this toilet backs up | In the toilet or its trap | Plunge or use an auger |
| Toilet and tub gurgle together | Branch line | Call a plumber, see drain cleaning |
| Several fixtures back up, floor drains too | Main sewer line | Stop using water and call, see sewer line cleaning |
| Repeats after clearing | Restriction beyond the toilet | Camera inspection, see sewer inspection |
Why toilets clog in the first place
The biggest cause is flushing things that do not break down, such as wipes marketed as flushable, paper towels, and feminine products. They do not dissolve like toilet paper, and they snag in the trap or a bend in the line.
Too much toilet paper can also clog a low flow toilet. A weak flush, a partially blocked vent, or a rough pipe joint adds to the problem. If clogs return every few weeks, the line behind the toilet needs a look.
When the backup is in the sewer line
The Town of Sahuarita's Wastewater Department serves more than 5,500 customers and takes calls at 520-344-7100. If several fixtures back up at once, the cause may be in your private line or in the public sewer main. The Town's page does not say who is responsible for what, so ask the department when you call.
If you live in Green Valley, which is unincorporated, your sewer service may come from a different provider. Ask your own utility. Either way, stop using water until the line is checked, since every flush adds to the backup.
Cleaning up after an overflow
Sewage-contaminated water is a health concern, so wear gloves and boots. Remove standing water, disinfect hard surfaces, and dry carpet and drywall quickly. Porous materials soaked by dirty water often need to be removed.
Document the damage with photos for your insurer. If the cleanup is large, a restoration company handles drying and demolition, and we handle the plumbing.
When to call a plumber
Call if the plunger and auger do not work, if more than one fixture is affected, if the clog keeps returning, or if water is rising fast. A plumber can clear the line and, if needed, run a camera to see what is wrong.
Our toilet repair page covers the fixture itself. For a main line backup, call our 24/7 line and stop using water in the meantime.
How to prevent the next clog
Flush only toilet paper and human waste. Put wipes, paper towels, and other products in the trash, even if the package says flushable. Use a moderate amount of paper per flush, and flush twice if needed.
If you have young children, keep the lid down and teach them not to flush toys or extra paper. A basket in the bathroom for non-flushable items makes it easy for guests to do the right thing.
Tools worth keeping at home
A small kit saves a late-night call for minor clogs.
- A flange plunger made for toilets.
- A closet auger with a protective sleeve.
- Rubber gloves and a bucket.
- Old towels and a mop.
- The number of a plumber who answers at night, such as our 24/7 line.
Why traps and vents matter
Every fixture needs a trap and a vent to work well. The trap holds a water seal against sewer gas, and the vent lets air in so water can drain, though how they must be arranged is set by the plumbing code your building department enforces.
Toilet manufacturers' guidelines say to flush only toilet paper and human waste. A toilet that gurgles or clogs often may point to a vent or line problem, not just the bowl.
Clogged toilet questions from Sahuarita homeowners
Should I flush again to see if it clears?
No. A second flush can overflow the bowl.
Does hot water and dish soap work?
It can for a soft clog. Use hot tap water, not boiling.
Why does my toilet clog every few weeks?
A restriction in the trap or the line is likely. A camera shows the cause.
