Now versus later
| Calling right away | Waiting for business hours |
|---|---|
| Protects floors and cabinets from water or sewage | Time to check licenses and compare |
| May cost more after hours | Requires stopping water use at that sink |
| Fewer choices of plumber | Not appropriate if sewage is involved |
The cost of waiting
A slow sink left alone usually stops eventually, and it tends to stop at the worst moment, such as during a holiday meal. A sink that is fully stopped but contained is inconvenient rather than dangerous. Sewage, active leaks and chemicals are the cases where waiting can damage the home or put people at risk.
Common questions
Is a stopped kitchen sink an emergency?
Usually not, if the water is contained and no other drains are affected. Stop using it and call during normal hours.
What makes it urgent?
Sewage in other fixtures, leaks you cannot stop, chemicals in a full sink, or water reaching floors and walls.
Can I use the other basin while I wait?
Not if they share a trap, which most double sinks do. Water will just rise on the clogged side.
