Nothing is more frustrating than turning on the faucet or shower only to find low water pressure slowing everything down. Whether you're struggling with a trickle from your kitchen sink, bathroom faucet, or showerhead, this issue can be annoying—and sometimes a sign of a bigger problem.
If you're dealing with low water pressure in your home, here are 7 common causes and how to fix them!
1. Clogged Aerators or Showerheads
Over time, mineral buildup from hard water can clog your aerators and showerheads, reducing water flow.
✅ How to Fix It:
- Unscrew the aerator or showerhead.
- Soak it in vinegar overnight to break down mineral deposits.
- Scrub with a toothbrush and reattach.
2. Partially Closed Shut-Off Valve
Your home’s main water valve controls how much water flows into your plumbing system. If it’s not fully open, you’ll experience low pressure.
✅ How to Fix It:
- Locate your main water shut-off valve (usually near the water meter).
- Turn it counterclockwise to ensure it’s fully open.
3. Faulty Pressure Regulator
A pressure regulator controls your home’s water pressure. If it’s malfunctioning, it could be lowering your water pressure unexpectedly.
✅ How to Fix It:
- Check your water pressure using a gauge (sold at hardware stores).
- If it’s too low, you may need a new pressure regulator—contact a licensed plumber for replacement.
4. Leaking Pipes
Leaks in your plumbing system can divert water away from your fixtures, leading to noticeable low pressure.
✅ How to Fix It:
- Check for wet spots, water stains, or unusual puddles around pipes.
- If you suspect a leak, call a professional plumber for an inspection.
5. Sediment Buildup in Pipes
Over time, pipes can accumulate rust, dirt, and mineral deposits, restricting water flow. This is especially common in older homes.
✅ How to Fix It:
- If only one fixture is affected, it may just be a localized clog.
- If the whole house has low pressure, you may need a plumber to flush your pipes.
6. Issues With Your Water Heater
If you’re only experiencing low hot water pressure, your water heater might be the culprit.
✅ How to Fix It:
- Check the heater’s shut-off valve to ensure it’s fully open.
- If the issue persists, your tank may have sediment buildup—it might be time for a professional water heater flush or replacement.
7. Municipal Water Supply Problems
Sometimes, low water pressure isn’t your fault—it could be due to city water supply issues or nearby plumbing work.
✅ How to Fix It:
- Ask neighbors if they’re experiencing the same problem.
- Contact your local water department to check for maintenance issues.
