Water in a Light Fixture in a Laguna Beach Home: What to Do First and Where It Comes From
Water dripping from a ceiling light is both an electrical hazard and a sign of a leak above. Here is what Laguna Beach homeowners should do right away and how to…
Water pooling in a ceiling light or dripping from a fixture is one of the more alarming things to find at home. Light fixtures sit in holes cut through the ceiling, so they are often the first place water escapes when something above is leaking. In Laguna Beach, with its mix of older hillside cottages, multi-level homes and flat roofs, the source can be plumbing or weather.
Safety first
- Do not touch the fixture or the switch while water is present.
- Turn off the circuit for that light at the electrical panel.
- Put a bucket under the drip and keep people and pets away.
- If water is coming fast, shut off the main water valve.
Once the fixture has fully dried, have it checked before turning the circuit back on.
Plumbing or rain?
Timing is the best clue:
- If the drip started during or right after rain, the roof, a deck above, a skylight or a window is a likely source.
- If it appears after a shower, a toilet flush or using a sink upstairs, a drain or supply line is more likely.
- If it drips steadily no matter what is in use, a pressurized supply line is a strong possibility.
Shut off the main water valve and watch. If the dripping slows and stops over the next hour, a supply line is likely involved.
Common plumbing sources above a light
- A toilet supply line or wax seal on the floor above.
- A tub or shower drain, overflow or valve.
- A supply line running through the ceiling to an upstairs bathroom.
- A water heater or laundry on an upper level.
- Condensation from an air handler in the attic or ceiling space.
Multi-level homes
Many Laguna Beach homes step down a hillside, with bathrooms stacked over living areas or garages. Water can follow a joist or pipe for some distance before dropping at a light, so the leak may not be directly above the fixture.
After the leak is found
Ceiling drywall that has been soaked should be opened and dried, not just painted over. Insulation above the ceiling may need to be removed and replaced if it stays wet.
Quick takeaways
- Turn off the circuit before anything else.
- Rain timing points to the roof; fixture use points to plumbing.
- Shutting off the main is a quick way to test for a supply leak.
- Water travels along framing, so the source may be several feet away.
