The short answer
Common Causes
A dry P-trap is a frequent culprit. The P-trap is the curved pipe under sinks and showers that holds water to block sewer gases. If the room has been empty for a while, the water can evaporate, letting odors rise through the drain.
Another cause is a blocked or improperly vented drain pipe. Sewer gases need a way to escape through the roof vent. If that vent is clogged with debris, the gas may back up into the room. A leak in the drain line behind the wall can also produce a sewage smell.
What to Do First
Do not ignore the smell. Sewer gas can be unpleasant and may cause headaches or nausea. Open a window if possible, and leave the room for fresh air. Avoid using the bathroom or running water until the issue is addressed.
Report the problem to the hotel front desk. They should have maintenance check the room. If you feel unwell, see a doctor. Your safety is the priority, and the hotel is responsible for fixing the problem.
- Open a window for ventilation
- Leave the room and seek fresh air
- Do not use the sink, shower, or toilet
- Tell the front desk immediately
- See a doctor if you feel unwell
What the Pros Check
When a hotel calls in water damage pros, they start by inspecting the plumbing vents and drains. They look for dry P-traps, blockages, or leaks. They may use leak detection tools to find hidden problems behind walls or under floors.
If there is sewage backup, the pros handle cleanup and sanitation. That includes removing contaminated materials and disinfecting the area. They also dry and dehumidify to prevent mold. The goal is to find the source and stop the odor at its origin.
If It Gets Worse
If the smell becomes strong or you see water damage, do not stay in the room. Ask the hotel for a different room. If the problem seems serious, consider contacting your insurance company about any personal belongings affected.
Policies vary, and your insurer decides what is covered. Keep receipts for any expenses, but focus on your health and comfort. A hotel should resolve this quickly, and you have the right to a safe space without odors.
Preventing Future Odors
Hotels can prevent sewage smells by keeping drains filled with water during vacancies. A little water down each drain every few days helps. Regular maintenance of vents and pipes is also important.
If you live in Redmond, you can apply the same advice at home. Run water in every sink and shower at least weekly. Keep the vent pipes clear. If you smell sewage, call a plumber or water damage pro to inspect.
- Run water in all drains weekly
- Keep vent pipes clear of debris
