Leak observations: wet areas, drips & damp patches
You open the cabinet and notice water. Or a spot feels damp again, even after it looked dry. Call about your leak concern with the location and timing you have noticed. You do not need to know which part is involved.

Useful information / not a diagnosis
What can you describe without taking anything apart?
| Observation | Detail to share | Decision it helps you discuss |
|---|---|---|
| Visible drip or puddle | Room, nearest fixture and whether water is visible now. | Whether the concern can be assessed. |
| Damp patch or an old mark | Where you saw it and whether it has appeared before. | What information would help explain the source. |
| Water noticed during normal use | Timing you already know; do not recreate the leak. | What access or existing records might be helpful. |
01 / Observation guide
Begin with the spot you can see.
Describe the room and the nearest fixture: the cabinet below a kitchen sink, the floor beside a toilet, or a patch near a bathroom basin. Say whether you see a drip, a puddle, a stain, or simply dampness. Those are different observations; you do not have to turn them into a diagnosis.
Keep the description literal. “The cabinet is wet at the back” is more useful than guessing that a particular pipe has failed. Only share what you can observe without opening walls or taking fixtures apart.
02 / Observation guide
Timing helps you explain the change.
Did you first notice it today, or has it happened more than once? If you already know, mention whether it appeared while a fixture was in use or while nothing nearby was running. Do not recreate a leak just to test a theory.
- Which room or visible area is affected?
- Is there visible water now, or a mark from earlier?
- Has the area changed since you first noticed it?
- Has there been recent work that you can describe?
03 / Observation guide
Ask what an assessment would involve.
Tell Pedro what you see and ask whether the concern and your address can be accommodated. Ask how the initial visit is arranged, what access is needed, and how any assessment charge is explained.
A damp spot alone cannot establish where water began or what work is needed. Ask how findings and proposed work would be discussed before you agree to proceed. You do not need to select a repair method over the phone.
04 / Observation guide
Is the main issue water draining away?
If water remains in the basin or returns through a drain, the drain and sewer enquiry page is a better starting point. If a faucet or toilet behaves differently but you are not seeing escaped water, try the fixture and toilet guide.
Ask about this concern at your property.
Call Pedro Sewer Drain and Plumbing Service at (619) 993-4204. Share your address and ask about the concern, assessment options and any visit charge.
Contact & location →Common questions
Before you call
Do I need to locate the source before calling?
No. Describe the visible wet area and when you noticed it. Avoid dismantling a fixture or opening a wall to get more detail for the call.
What if the area has dried?
Mention where it was wet, when you saw it, and whether it has happened before. A dry surface at the time of your call does not explain what caused the earlier water.
Should I send photographs?
If you already have a photo, mention it on the call and ask whether there is a suitable way to share it. This website has no photo upload or message form.
