Why Is Your Water Pressure Low? All Your Questions Answered
Low water pressure is one of the more frustrating and confusing issues a homeowner can face. While you can sometimes DIY an AC issue by swapping out a filter or repair a squeaky door by spraying some WD-40, plumbing issues are often more difficult to diagnose and fix.
Low water pressure is a common issue in San Jose because of the city’s older pipes, hard water build-up, and municipal water supply. Why is your water pressure low? Troubleshoot with our guide to determine the problem and find the best solution.

5 Common Causes of Low Water Pressure in Homes (and How to Fix Them)
Why is the water pressure low in your house? You likely have one of these five causes to blame.
1. Clogged Aerators
The aerator in your faucet regulates your water flow and catches stray debris to keep contaminants out. If your aerator is clogged with excess mineral deposits, your water flow may be uneven.
Fix this issue by submerging your faucet head in a mixture of hot water and white vinegar to dissolve the deposits. Leave the faucet head for several minutes, then give it a good rinse and screw it back onto your faucet.
2. Showerhead Buildup
Hard water affects every pipe and fixture in the home. If your water pressure works fine in your kitchen, but your shower isn’t acting right, you likely have sediment buildup in your showerhead.
You can fix this issue by soaking your showerhead in hot water and white vinegar, which can help reverse your home water pressure issues by breaking up the mineral deposits.
3. Partially Closed Shutoff Valves
Your shutoff valve controls the flow of water into the home and is a must-have tool in the event of a surprise flood. If your shutoff valve is partially closed, it can cause water pressure problems in your appliances.
Sometimes a shutoff valve can be left partially closed after a repair job or maintenance visit. You can find your valve near your water heater or, if you have a basement, in the area where water enters. Simply twist the handle counterclockwise to reopen it.
4. Clogged Pipes
Pipes constantly move water in and out of your home. In addition to all that water, they carry food particles, hair, and mineral buildup that gradually sticks to the sides of the pipe. Over time, a clog can form that makes your water flow sputter or slow to a complete stop.
You can sometimes clear a minor clog with a gentle, enzyme-based clog remover. If the clog is shallow, you can also try a drain snake to pull out the debris.
5.Hidden Leaks
Sometimes the reason why your water pressure is low is that your water supply is low. While this will sometimes be obvious, such as a dripping pipe beneath your bathroom sink, it can also be completely hidden without your knowledge.
Over time, this constant leakage affects your water flow, as different areas of the home lose their usual water supply. You’ll need a skilled plumber to visit your home and patch the leak.
How to Diagnose Water Pressure Problems
Not sure if you’re dealing with low water pressure in the house? Narrow the problem by seeing if any of these details match your situation:
Your issue is isolated to a specific part of the house. This issue usually signals sediment buildup or a clog.
Your water flow problems affect multiple fixtures. You likely have a shutoff valve issue or damage to your pipes.
The water flow has gradually gotten more unreliable. Your home probably has a growing, hidden leak.
