A sudden drop in home water pressure across multiple fixtures is typically triggered by a municipal water main break, scheduled public utility pipe maintenance, a clogged whole-house sediment filter, a failing well pump pressure switch, or a partially closed main water shutoff valve. When debris clogs the main filter cartridge or the utility supply drops, water delivery across all household fixtures decreases instantly. Verification: Check whether pressure is low at only one tap or across every fixture in the house.
