Few things are more frustrating than turning on the shower and getting a weak trickle instead of a steady stream. If your water pressure low at home situation has you rinsing shampoo longer than usual or waiting forever to fill a pot, you’re not alone.
Low water pressure is one of the most common plumbing complaints homeowners face. The good news? It’s often fixable. The key is identifying whether the issue is minor — like a clogged fixture — or something more serious, like a hidden leak or pipe corrosion.
In this guide, we’ll walk you through what to check when your water pressure is low at home, what causes it, and when it’s time to call in a professional.

What Is Considered Low Water Pressure?
Normal residential water pressure typically ranges between 40 and 60 PSI (pounds per square inch).
You may have water pressure low at home if you notice:
Sometimes the issue affects only one faucet. Other times, it’s the entire house. That difference matters.
If the problem is isolated, it’s usually a fixture issue. If it’s widespread, the cause may be deeper in your plumbing system.

Check for Clogged Faucet Aerators or Showerheads
This is the simplest and most overlooked cause.
Over time, mineral deposits and sediment build up inside faucet aerators and showerheads — especially in South Florida where water hardness varies.
Signs this is the issue:
Unscrew the aerator and soak it in vinegar to dissolve mineral deposits. If pressure improves afterward, you’ve found your culprit.
If not, move to the next step.
Make Sure the Shut-Off Valves Are Fully Open
Your home has two main water shut-off valves:
If either is partially closed — sometimes after repairs — it can restrict flow and cause water pressure low at home throughout the property.
Check that both valves are fully open. Even being slightly turned can reduce pressure.
If adjusting the valve doesn’t fix it, the issue may be internal.
Call Dovis Plumbing at (954) 516-1078 to diagnose the restriction correctly.
Look for Hidden Water Leaks
A hidden leak is one of the most serious reasons for water pressure low at home.
When water escapes before reaching your fixtures, pressure drops.
Warning signs of a hidden leak include:
Leaks not only reduce pressure but also cause structural damage.
If you suspect a leak, don’t wait. The longer it continues, the more expensive it becomes.
Check the Pressure Regulator (PRV)
Many homes have a pressure-reducing valve (PRV) that controls water pressure entering the house.
If the PRV fails, it can cause:
PRVs typically last 7–12 years. If yours hasn’t been replaced in that timeframe, it could be failing.
Testing requires a pressure gauge and proper evaluation.
Call Dovis Plumbing at (954) 516-1078 to inspect your pressure regulator.
Corroded or Aging Pipes
If your home is older, internal pipe corrosion may be the cause of water pressure low at home.
Galvanized steel pipes, common in older homes, corrode over time. As rust builds up inside the pipe walls, it restricts water flow.
Signs corrosion may be the issue:
Unfortunately, pipe corrosion often requires repiping to fully resolve.
Temporary fixes won’t restore proper flow if the pipe diameter has narrowed internally.
Municipal Water Supply Issues
Sometimes, the issue isn’t inside your home at all.
City water supply problems can cause:
If neighbors are experiencing the same issue, the problem may be municipal.
However, if it’s only your home, the issue is likely internal.
Simultaneous Water Usage
Modern households use more water than ever.
If multiple appliances run at once:
Pressure may drop temporarily.
If this happens frequently, your plumbing system may not be sized for your household’s demand.
Upgrading fixtures or improving system flow can help.
