SECTION 2: QUESTION AND ANSWER
A bad smell usually comes from a dry trap, which no longer blocks sewer odours from rising through the drain, especially in a floor drain that is rarely used. A floor drain that backs up is different: it may point to a blockage further down the line or a wider drainage problem. Noting whether the drain smells, backs up, or both helps describe the problem when you call.
SECTION 3: SIGNS YOU NEED FLOOR DRAIN CLEANING
A floor drain problem can be a local problem in that drain, or a signal of a wider line problem. The next sections explain the three distinct floor-drain situations, so you can describe yours clearly.
DRY TRAP AND ODOUR
A floor drain has a trap that holds a small amount of water, and that water blocks smells from coming up through the drain. In a floor drain that is rarely used, the water in the trap can dry out, and then smells from the drain line can rise into the room. A dry trap is a common reason for a floor drain smell in a room where the drain is hardly ever used. Adding water to the trap can sometimes settle the smell, but if the smell keeps coming back, or the drain also drains slowly, the drain itself may need attention. Describe how often the drain is used when you call.
HOW A FLOOR DRAIN IS CLEARED
01
Describe what the floor drain is doing, smelling, draining slowly, or backing up, and whether any other fixture is affected.
02
The floor drain is checked to find whether the problem is a dry trap, a local blockage, or a wider line signal, in general terms.
03
A local blockage is cleared from the floor drain. A cable tool may be used for a floor-drain blockage, see Drain Snaking / Augering for the full method explanation.

SECTION 5: LOWEST DRAIN AS A SIGNAL
A floor drain is often the lowest drain in a building, so it can be the first place a wider line problem shows up. If water backs up through a floor drain when other fixtures are used, or several fixtures are affected at the same time, the problem may be further down the line rather than in the floor drain alone. That pattern matters, because a floor-drain-only problem and a wider line problem are handled differently. See Main Sewer Line Cleaning for the wider line picture.
SECTION 6: LAUNDRY AND UTILITY DRAINS
Floor drains in laundry and utility areas take water from washing machines and utility sinks, and they can collect lint and soap residue over time. Lint and soap can narrow the drain and slow it down, so a laundry drain may drain slowly even when nothing large has gone down it. A utility drain that is used for mopping or cleaning can also collect dirt and debris in the same way. If your laundry or utility drain drains slowly, or water stands around it after a wash, describe which drain is affected and what it is used for when you call.

FREQUENTLY ASKED QUESTIONS
A floor drain smell often comes from a dry trap, where the water that normally blocks smells has dried out because the drain is rarely used. Adding water to the trap can sometimes settle the smell. If the smell keeps coming back, or the drain also drains slowly, the drain itself may need attention.
Not always. A floor drain can back up because of a local blockage in that drain alone. But because a floor drain is often the lowest drain, backing up when other fixtures are used can point to a wider line problem. Describe every affected fixture when you call.
A laundry drain can slow down because lint and soap residue build up in the drain over time and narrow it. That buildup happens gradually, so the drain may drain more slowly week by week rather than blocking all at once. If water stands around the drain after a wash, describe which drain is affected when you call.
Avoid using nearby fixtures and keep clear of any standing water on the floor, because more water going down can make the backup worse. Note whether any other fixture is affected, and whether the problem happens when a particular fixture is used. Describe what happened when you call, so the problem can be understood clearly.
