Struggling with weak water flow in your shower or sink? Low water pressure in a house can make simple tasks like washing dishes, doing laundry, or taking a shower frustrating. Identifying the root cause can help restore strong water pressure and improve your daily routine.
Here are ten common causes of low water pressure in a house and the best ways to fix them.
Mineral deposits and debris can clog faucet aerators, restricting water flow. This is especially common in areas with hard water.
Solution: Remove the faucet aerator, soak it in vinegar overnight, and scrub away any buildup before reinstalling it.
Older homes with galvanized steel pipes often experience internal corrosion, reducing water flow over time.
Solution: If your home has aging pipes, consider replacing them with modern materials like copper or PEX to improve water pressure.
A leak in your plumbing system can cause a significant drop in water pressure by diverting water away from fixtures.
Solution: Look for damp spots, water stains, or an unusually high water bill. If you suspect a leak, contact Zenon Plumbing for a professional inspection.
Sometimes the issue is outside your home. Local water supply problems such as maintenance work, mainline breaks, or pressure reductions can impact household water flow.
Solution: Check with your local water provider to see if there is an issue in your area.
Many homes have a pressure regulator that controls water flow. A failing pressure regulator can cause sudden drops in water pressure.
Solution: A plumber can test and adjust the pressure regulator or replace it if necessary.
The main shut-off valve controls water flow into your home. If it’s not fully open, water pressure will be lower than normal.
Solution: Locate the main shut-off valve, usually near the water meter, and make sure it is completely open.
If your home has a water softener, a blockage in the system can reduce water pressure throughout the house.
Solution: Bypass the softener to see if the pressure improves. If it does, the unit may need maintenance or cleaning.
Water pressure may drop when multiple household members use water at the same time, such as in the morning when showers, dishwashers, and washing machines are in use.
Solution: Try adjusting water usage schedules or installing a pressure-boosting system.
If you experience low hot water pressure, the issue may be sediment buildup inside the water heater, reducing efficiency and restricting water flow.
Solution: Flush the water heater to remove sediment or schedule a professional maintenance service with Zenon Plumbing.

A break or blockage in the main water supply line leading to your home can cause a sudden drop in pressure.
Solution: If you suspect a problem with the main water line, contact Zenon Plumbing for professional repair services.
