Water drips from a ceiling when there is a leak somewhere above it. In most homes, the source is a bathroom overhead, a supply or drain pipe running through the ceiling, an appliance hose on the floor above, condensation on cold pipes, or rain coming through the roof. Watching when the drip happens is the fastest way to narrow it down.
A Quick Detective Test
If there is a bathroom above the drip, try each fixture one at a time:
1. Run the shower for five minutes, then check the ceiling
2. Fill and drain the tub, then check again
3. Flush the toilet several times
4. Run the sink
A drip that starts after one of these points to that fixture. A drip that never stops, even when nothing is used, usually means a pressurized supply line is leaking.
Common Bathroom Culprits
The wax ring under a toilet can fail and let water seep with every flush. Cracked grout or missing caulk around a tub lets shower water escape. A loose tub drain can leak slowly for months before a stain appears below.
Other Sources to Consider
Washing machine hoses and dishwasher connections upstairs can crack or loosen. In humid weather, cold water pipes may sweat and drip along their length. If the drip appears only during storms, the roof, flashing, or a window is the more likely cause, which calls for a roofer.
Protect the Room Below
Put a bucket under the drip and move furniture and electronics. Keep everyone out from under a ceiling that sags. Avoid wet light fixtures and switch off that circuit if you can reach the panel safely.
Once you have a likely source, the leaking toilet, tub, or line overhead can be fixed. Afterward, resealing tubs and showers on the upper floor can help prevent a repeat. Call JPR Plumbing at (833) 603-1840.
