A drain pipe leaks when water passes through it.
Stop using the fixture when draining sends water into a cabinet, wall, floor, or space below. A drain leak is not the same as a slow drain, even when both symptoms occur together. The pipe may be obstructed, a joint may leak, or another connection may be involved. Describe the escape of water first so the provider understands that simply restoring flow may not complete the job.

Treat escaping waste water as potentially contaminated. Keep people and pets away, avoid contact, and do not use a household vacuum or electrical equipment in the wet area. Tell the provider if sewage or water from more than one fixture is involved.
The fixture that triggers the leak may not own the whole pipe
A kitchen sink can share an accessible assembly with a dishwasher. Several bathroom fixtures can connect to a concealed branch. A lower-level pipe may carry waste from rooms above. Report which use was associated with the leak, but do not assume that the visible pipe serves only the nearest fixture.
If you know whether one or several drains were in use, include that information. In a shared building, notify management because other occupants may keep adding water to the affected line. Do not enter another unit or operate plumbing there. The person coordinating the building needs to arrange any restrictions or access across occupied spaces.
Leaking and backing up need separate explanations
Ask the provider whether the proposed work addresses a leaking connection, an obstruction, or both. A drain that empties freely after clearing may still leak through a defect. Conversely, replacing an accessible joint does not prove that the downstream route is clear. The scope should state which observed conditions will be checked.
Do not add chemical drain products to a pipe that is leaking. Tell the responder about any product already used, including the container information if safely available. Do not combine cleaners or try another chemical after the first failed. That information matters to the person who may open the line and handle its contents.
Accessible plastic fittings are not automatically a simple repair
A joint below a sink can look easy to tighten, but alignment, supporting parts, damaged threads, and unsuitable components may matter. Do not disassemble it just to see whether a washer is present. Keep the original arrangement visible for the provider, and do not substitute tape or sealant for identifying why it leaks.
For concealed piping, ask how the source will be located and which access route is proposed. A leak visible below a floor can originate elsewhere along the assembly. The proposed opening should be tied to observations rather than the assumption that the nearest wet point is the defect. See access planning before approving disturbance of finished surfaces.
If previous work changed the sink, disposal, or appliance arrangement, share that history. A provider may need to understand which connections were retained and which were altered. An old photograph can show the prior configuration, but it should be labeled with its date so it is not confused with the current installation.
Outdoor waste-line leakage has a different authority path
If the concern involves a buried sewer or drain line, the work may cross private property and the right-of-way. Portland's broken sewer and drain guide explains separate permit and inspection responsibilities. Shared or party sewers add questions that should be resolved with the appropriate City contact before repair.
Do not apply the water-supply meter boundary to a waste line. A water meter does not establish sewer ownership. Do not dig, probe soil, or open a cleanout yourself to determine where waste is escaping. The investigation needs appropriate locating, access, sanitary controls, and authorization for the segment involved.
Decide who owns cleanup and restoration
Ask the plumbing provider what it will contain, remove, or clean as part of the repair. A repaired pipe does not establish that contaminated or damp surrounding materials have been adequately addressed. The cleanup scope may need a separate experienced professional, especially where waste water reached porous material or an occupied room.
Keep the original damage and the repair access damage separately described. That distinction helps when comparing restoration proposals and prevents confusion about what each company agreed to restore. This site cannot assess contamination, determine health risk, or certify a room as safe from text or a photograph.
Check the repaired route under appropriate use
Ask how the provider verified the joint or pipe after work. Explain any appliance discharge or combined fixture use linked to the original leak so it can be considered in the testing plan. Do not perform your own repeated stress test before the professional has confirmed that use can resume.
Request a repair description that names the affected pipe section or connection, along with any required permit and inspection record. If a separate obstruction or pipe defect remains, ask who is handling that next step. A clear unresolved item is more useful than a vague statement that the system is “all good.”
