Plumbing
Low water pressure throughout the house (not just one fixture)
Likely cause, what to safely try first, and whether it gets worse if you wait.
Likely cause
Sediment/mineral buildup clogging aerators and pipes, a partially closed main valve, or a municipal supply issue.
What to try first
- Unscrew and clean the faucet aerator/showerhead first — mineral buildup there is the most common cause and a 2-minute fix.
- Confirm the main water shut-off valve (near the meter) is fully open, not partially closed.
- Ask a neighbor if they're having the same issue — that points to a municipal supply problem, not your plumbing.
