How to Fix Low Water Pressure in Your Home
Dealing with low water pressure in your home can be incredibly frustrating. Whether you’re struggling to rinse soap off in the shower, waiting ages for the sink to fill, or finding that your garden hose barely trickles, weak water flow can be a real nuisance. Fortunately, there are several common causes for low water pressure—and even better, there are effective solutions.
At Marv's Plumbing & Heating, we’ve helped countless homeowners in Cheyenne, WY restore proper water flow. Here’s a guide to help you troubleshoot and fix low water pressure in your home.
1. Check for Clogged Aerators and Showerheads
Over time, mineral deposits and sediment can build up in your faucets and showerheads, reducing water flow. This is especially common in areas like Cheyenne, where hard water is prevalent.
✅ How to Fix It:
Unscrew the aerator (the small screen at the tip of the faucet) or the showerhead.
Soak it in a vinegar solution for a few hours to break down the mineral buildup.
Scrub away any remaining debris with a small brush, rinse it thoroughly, and reattach it.
If the pressure improves, the aerator or showerhead was the culprit.
2. Inspect Your Pressure Regulator
Most homes have a pressure regulator that controls the flow of water coming in from the main line. If this device is malfunctioning, it can significantly reduce your home’s water pressure.
✅ How to Check It:
Locate the pressure regulator (typically near the main water shut-off valve).
Use a water pressure gauge to check the pressure. A healthy range is usually between 40–60 psi.
If the pressure is too low, you may need to adjust or replace the regulator.
Pro Tip: Adjusting a pressure regulator can be tricky. If you’re unsure, call a professional plumber for assistance.
3. Look for Hidden Leaks
Hidden water leaks can cause a drop in pressure without any obvious signs. Even small leaks can reduce the overall flow of water throughout your home.
✅ How to Detect a Leak:
Turn off all water appliances and check your water meter.
If the meter continues to run, you likely have a leak.
Inspect visible pipes for moisture, but keep in mind that leaks can also occur behind walls or underground.
If you suspect a leak, it’s best to have a professional locate and repair it before it causes further damage.
4. Clear Out Clogged Pipes
Sediment and mineral deposits can build up inside your pipes over time, restricting water flow. This is particularly common in older homes with galvanized pipes.
✅ How to Address It:
If only one or two fixtures have low pressure, the issue is likely local to those pipes.
For whole-house low pressure, you may need to have your pipes cleaned or replaced.
Flushing your water heater annually can also prevent sediment from building up in the lines.
5. Check the Main Shut-Off Valve
If you’ve recently had plumbing work done or accidentally bumped the main water shut-off valve, it may not be fully open. A partially closed valve can reduce water pressure throughout your home.
✅ How to Fix It:
Locate the main shut-off valve (usually in the basement, utility room, or outside).
Ensure it is fully open by turning it counterclockwise.
