What Causes Low Water Pressure and How to Fix It

Low water pressure can make everyday tasks like showering and washing dishes frustrating. While some causes of low water pressure are easy to fix, others may require professional intervention.

Common Causes of Low Water Pressure

5. Municipal Supply Issues

Sometimes the problem lies with your water supplier. Maintenance, pipe damage, or high demand in your area can temporarily reduce water pressure.
