 Buzzing/vibrating noise
Author: tree (NJ)

I'm a senior citizen and I desperately need help. I'm not sure who to call, a plumber or an electrician. About an hour ago, I was using my sink in the half-bath. All of a sudden, I've got this buzzing/vibrating noise I believe is coming from in the wall. I've shut the water and the electric off, but the noise is still going. I'd truly appreciate any help you can offer. It's been buzzing about an hour now.

Is it still buzzing? For how long? Is the bathroom on an exterior wall? Is there another bathroom or apartment behind it? More information please.

Is it possible an electric razor or toothbrush started running in a medicine cabinet or vanity?

Here are a few potential causes and steps you can take:
1. Plumbing issue: The noise could be related to a plumbing problem, such as a faulty valve, water hammer, or a loose pipe. While you've shut off the water, the noise may continue for a short period due to residual water pressure. If the noise persists after some time, it's advisable to consult a professional plumber to inspect the plumbing system and identify the source of the issue.

2. Electrical issue: The buzzing noise could be caused by an electrical problem, such as a loose electrical connection or a faulty electrical component. Even though you've shut off the electricity, there might be a device or circuit in the wall that still has power. To address this, consider switching off the main electrical circuit breaker to cut power to the entire house temporarily. If the buzzing noise continues even with the electricity completely shut off, it's crucial to contact a licensed electrician to investigate and resolve the issue.

3. HVAC system: The noise could be originating from the heating, ventilation, and air conditioning (HVAC) system, particularly if there are ducts or pipes running through the walls. Check if the noise coincides with the HVAC system turning on or off. If so, it could be due to a malfunctioning motor or a loose component within the system. Contact an HVAC technician to inspect and service the system.

Given the persistent nature of the noise, it's advisable to seek professional assistance from a plumber, electrician, or HVAC technician, depending on the likely source of the problem.
