Water Pressure Problems? Common Causes & Fixes
Water pressure issues can be frustrating, whether you’re dealing with a weak trickle from your shower or pipes that seem to blast water too forcefully. Understanding the common causes of water pressure problems and their solutions can help you restore proper flow in your home or business.
Common Causes of Low Water Pressure
1. Clogged Pipes
Signs: Slow water flow from faucets or inconsistent pressure.Fix: Flush the system with a pipe-cleaning solution or consult a plumber for professional cleaning if blockages are severe.
2. Leaks in the Plumbing System
Signs: Visible water damage, unusually high water bills, or wet spots on floors or walls.Fix: Inspect for leaks, tighten loose connections, and replace damaged pipes or fittings.
3. Faulty Pressure Regulator
Signs: Water pressure that is too high or too low throughout the home.Fix: Test the regulator with a water pressure gauge and replace it if readings are outside the normal range (40-60 psi).
4. Corroded Pipes
Signs: Rust-colored water, uneven water flow, or frequent pipe leaks.Fix: Replace old, corroded pipes with newer materials like PEX or copper.
5. Municipal Water Supply Issues
Signs: Low pressure across your entire property, especially after maintenance or construction nearby.Fix: Contact your water provider to check for system issues or consider installing a booster pump if pressure problems persist.
6. Partially Closed Shut-Off Valves
Signs: Lower pressure at all fixtures after recent plumbing work.Fix: Ensure the main shut-off valve and water meter valve are fully open.
Common Causes of High Water Pressure
1. Malfunctioning Pressure Regulator
Signs: Banging pipes (water hammer), excessive water flow, and frequent plumbing leaks.Fix: Adjust or replace the regulator to keep pressure within safe levels (below 80 psi).
2. Thermal Expansion in Water Heater
Signs: Sudden bursts of high pressure or dripping from the temperature and pressure relief (T&P) valve.Fix: Install an expansion tank to regulate pressure changes.
3. High Municipal Water Pressure
Signs: Constantly strong water flow, even at low faucet settings.Fix: Install a pressure-reducing valve (PRV) to control incoming pressure from the main line.
How to Check Your Water Pressure
To determine if your water pressure is within the normal range:
- Attach a water pressure gauge to an outdoor spigot.
- Fully open the tap and check the reading.
- Normal pressure: 40-60 psi.
- Too high: Above 80 psi (risk of damage to pipes and fixtures).
- Too low: Below 40 psi (may indicate plumbing issues).
Water pressure problems can stem from a variety of causes, from simple valve adjustments to major pipe replacements. Regular maintenance and prompt repairs can help keep your plumbing system running smoothly. If you're unable to resolve pressure issues on your own, consider consulting a professional plumber for a thorough inspection and solution.
