Low water pressure turns a shower into a trickle and doubles the time to fill a pot. Sometimes the fix is a five-minute cleaning; other times it points to a bigger plumbing issue. Here are the usual causes.
1. Clogged aerators
Mineral deposits build up in faucet aerators and showerheads. Unscrew and soak them in vinegar — this alone fixes many 'low pressure' complaints at a single fixture.
2. Partially closed valves
Check that your main shut-off valve and any fixture valves are fully open. A partially closed valve throttles flow.
3. Pressure regulator failure
Many NJ homes have a pressure-reducing valve where the line enters. When it fails, pressure can drop across the whole house.
4. Corroded or clogged pipes
Older galvanized pipes corrode and narrow internally, choking flow. This is common in homes with original mid-century plumbing.
5. Hidden leaks
Water escaping through a leak never reaches your fixtures. A sudden pressure drop plus a high bill suggests a leak.
6. Water heater issues
If only your hot water is weak, sediment in the water heater or a clogged hot line may be the cause.
7. Municipal supply issues
Sometimes the problem is upstream. If neighbors have the same issue, contact your water utility.
