Why Is My Water Pressure Low? And How Do I Fix It?

Introduction
Low water pressure can be a frustrating issue, whether you’re trying to take a shower, wash dishes, or water your garden. But why does it happen, and how can you fix it? Let’s explore the common causes of low water pressure and practical solutions to restore your water flow.
1. City Water Pressure Limits
In Calgary, the city guarantees a water pressure of about 45 PSI (pounds per square inch) to your home. However, many people are accustomed to higher pressure, around 70 to 80 PSI. If the city is only delivering 40 to 45 PSI, there’s little they can do to increase it. In such cases, homeowners may need to consider installing a booster pump, which can cost between 2,500 and 2,500 and 4,000. While this is a significant investment, it’s often the only solution for homes with consistently low pressure from the municipal supply.
2. Flow Restrictors and Reduced Flow Appliances
One of the most common causes of low water pressure is the presence of flow restrictors in faucets, showerheads, and other fixtures. Many modern appliances are designed to conserve water, reducing flow rates from 2.5–3 gallons per minute to as low as 1.25–1.75 gallons per minute. While this is great for the environment, it can leave you feeling like your water pressure is inadequate. To fix this, you can either remove the flow restrictors (if possible) or replace the fixtures with ones that offer higher flow rates.
3. Plumbing Issues in Your Home
Sometimes, the problem lies within your home’s plumbing system. Clogged pipes, leaks, or improperly sized pipes can all contribute to low water pressure. If you suspect an internal issue, it’s best to call a professional plumber to inspect your system. During routine maintenance visits, plumbers can also check your water pressure and provide recommendations tailored to your home.
Conclusion
How to Diagnose and Fix Low Water Pressure
- Check Your Fixtures: Start by testing the water pressure in different areas of your home. If the issue is isolated to one fixture, it’s likely due to a flow restrictor or a clogged aerator.
- Inspect Your Main Water Valve: Ensure the main water valve is fully open. A partially closed valve can significantly reduce water pressure.
- Consult a Professional: If the problem persists, schedule a plumbing inspection. A plumber can identify whether the issue is with your home’s plumbing or the city’s supply and suggest appropriate solutions.
Prevention and Maintenance
Regular maintenance is key to avoiding low water pressure issues. Schedule annual plumbing check-ups to ensure your system is functioning optimally. If you’re building or renovating, consider installing fixtures that balance water conservation with adequate pressure.
