If your showers feel more like drizzles and filling the bathtub takes forever, low water pressure can be more than frustrating—it can disrupt your entire day. In Philadelphia and Delaware County, homeowners frequently run into this problem, but understanding the causes and knowing how to fix them can save you time and headaches.
Common Causes of Low Water Pressure
There are many reasons why you may be experiencing low water pressure. Below are some common causes, but to diagnose your specific problem the best bet is to contact a licensed plumbing professional.
Municipal Water Supply Fluctuations
Sometimes low water pressure isn’t your plumbing at all—it can come from the city’s water system. Older neighborhoods in Philadelphia can occasionally experience temporary drops in pressure. If your neighbors are noticing the same thing, it’s likely an external issue.
Partially Closed Main Shutoff Valve
Your home’s main water valve controls the flow of water into your plumbing. If it isn’t fully open, water pressure throughout the house can drop. Check in your basement or utility area to make sure it’s turned completely counterclockwise.
Clogged Pipes
Sediment buildup or corrosion, especially in older pipes, can restrict flow. This is common in many Delaware County homes. If low pressure is limited to certain faucets or areas, it could be a sign of clogged pipes that need professional attention.
Faulty Pressure Regulator
Many homes have a pressure-reducing valve (PRV) to protect plumbing from high pressure. Over time, a PRV can wear out, causing persistent low water pressure throughout the home.
Leaks in the System
Hidden leaks reduce the water reaching your faucets. If pressure drops gradually or your water bill spikes unexpectedly, it could signal a leak behind walls or under the floor slab. Professional leak detection can pinpoint the problem before it worsens.
Fixture-Specific Issues
Sometimes the culprit is one faucet or showerhead. Mineral deposits, worn washers, or corroded cartridges can reduce flow. Cleaning or replacing these parts often restores normal pressure.
Simple Fixes You Can Try
- Ensure the main valve is fully open
- Remove and clean faucet aerators or showerheads
- Consider professional inspection for PRV adjustment or pipe cleaning
- Avoid harsh chemical drain cleaners on older pipes
