Common Causes of Low Water Pressure (And How to Fix Them)

Low water pressure can be more than just a minor annoyance—it can interfere with daily tasks like showering, doing dishes, or watering the lawn. If you’ve noticed a sudden drop in water pressure or have been dealing with weak flow for a while, it’s time to identify the root cause. At Russell Services, we help homeowners in Danbury and surrounding areas diagnose and fix low water pressure issues quickly and effectively. Here’s what might be behind the problem—and what you can do about it.


1. Clogged Pipes

Over time, mineral deposits, rust, and debris can build up inside your pipes and restrict water flow.

Signs:

  • Gradual drop in pressure over time
  • Uneven water pressure in different fixtures

Fix: A professional plumber can inspect your plumbing lines and flush or replace sections of pipe if necessary.


2. Faulty Fixtures

Sometimes the issue isn’t with your pipes, but with the faucet or showerhead itself. Sediment buildup or a worn-out aerator can reduce water flow.

Fix:

  • Unscrew the aerator or showerhead and clean it with vinegar
  • Replace the fixture if cleaning doesn’t help

3. Corroded Plumbing

Homes with older galvanized steel pipes are particularly susceptible to corrosion, which can gradually close off pipe interiors.

Fix: A licensed plumber may recommend replacing old piping with copper or PEX for a long-term solution.


4. Leaking Pipes

Leaks divert water before it reaches your fixtures, causing noticeable drops in pressure.

Signs:

  • Unexplained increases in water bills
  • Damp spots on walls, floors, or ceilings

Fix: Call a plumber immediately to detect and repair hidden leaks before they cause structural damage.


5. Municipal Supply Issues

Sometimes the problem originates outside your home. If your neighbors are experiencing similar pressure issues, the water company may be performing maintenance or repairs.

Fix: Call your local water supplier to confirm if there are any known issues. If not, have a plumber check your pressure regulator.


6. Pressure Regulator Problems

If your home has a pressure regulator, it could be malfunctioning. These devices control the pressure from the main water line into your home.

Fix: Have a plumber test the regulator and adjust or replace it if needed.


7. Partially Closed Shut-Off Valve

If the main shut-off valve or the water meter valve isn’t fully open, it can limit water flow to your entire home.

Fix: Check both valves and ensure they’re completely open. If you’re unsure, a professional can inspect and adjust them for you.
