What Causes Low Water Pressure?
Low water pressure can make everyday tasks like showering, washing dishes, and doing laundry frustrating. Understanding the common causes can help you determine whether the issue requires professional plumbing service.
Published
If low pressure affects only one fixture, the problem is likely localized — a clogged aerator, a partially closed valve, or a supply line issue. Cleaning the aerator or checking the shut-off valve under the sink often resolves these single-fixture problems.
If low pressure affects your entire home, the issue may be more significant. Common whole-home causes include a failing pressure regulator, corroded galvanized pipes that have narrowed over time, a partially closed main shut-off valve, or a leak somewhere in the supply line.
Hard water is common across Southeast Idaho and can cause mineral deposits to build up inside pipes and fixtures over time, gradually reducing flow. Homes in American Falls, Pocatello, Blackfoot, and surrounding areas are particularly susceptible to this issue.
Key Points to Remember
- Clogged faucet aerators or showerheads
- Partially closed shut-off valves
- Failing or misadjusted pressure regulator
- Corroded or mineral-clogged pipes
- Hidden water leaks reducing pressure
- Municipal water supply issues

What causes low water pressure?
Low water pressure in a single fixture is usually caused by a clogged aerator or partially closed valve. When the entire home is affected, common causes include a failing pressure regulator, corroded galvanized pipes, a partially closed main shut-off valve, or hidden leaks. In Southeast Idaho, hard water mineral buildup inside pipes is also a frequent cause of gradually decreasing water pressure.
