Your water system could be losing pressure for several reasons, often related to increased water demand or leaks.
Here's a breakdown of potential causes:
Increased Water Usage
- High Demand: One common reason for a drop in water pressure is simply increased demand.
- Example: Drought and periods of heavy water usage could be the cause. If many people in your area are using water at the same time (e.g., watering lawns, filling pools), the overall pressure in the system can decrease, affecting your home.
- New Appliances/Fixtures: A significant pressure drop can occur after installing new water-using appliances or expanding your plumbing system.
- Example: If you've recently built a home addition with an extra kitchen or bathroom, the increased water demand may strain your existing system and cause a drop in pressure.
- Irrigation Systems: Installing a new irrigation system can also significantly impact water pressure, especially if not properly sized for your existing plumbing.
Leaks
- Hidden Leaks: Undetected leaks are a frequent culprit behind pressure loss. These can occur in pipes under slabs, in walls, or underground.
- Fixture Leaks: Check all faucets, toilets, and showerheads for drips or leaks. Even small, continuous leaks can gradually reduce pressure.
Plumbing Issues
- Pressure Regulator Malfunction: Your home's pressure regulator is responsible for maintaining a consistent water pressure. If it fails, it can lead to either excessively high or low pressure.
- Clogged Pipes: Mineral buildup or debris inside pipes can restrict water flow, leading to reduced pressure.
- Closed or Partially Closed Valves: Ensure that all valves connected to your water system are fully open. Sometimes, a valve may be accidentally partially closed, restricting water flow.
External Factors
- Municipal Water Supply Issues: Sometimes, the problem isn't in your home at all. Check with your local water utility to see if they are experiencing any issues that might be affecting water pressure in your area. These could include:
- Main breaks
- Planned maintenance
- High demand on the system
In summary, identifying the cause of your water pressure loss requires a systematic approach. Consider recent changes to your plumbing, check for leaks, and investigate potential issues with your pressure regulator or municipal water supply.
