There’s nothing worse than stepping into the shower expecting a strong, refreshing stream—only to be met with a weak drizzle. If you’ve noticed low water pressure in your shower, you’re not alone. This is a common plumbing complaint and one that often points to a bigger issue.

Here are five of the most common reasons your shower might be suffering from low water pressure—and what you can do about it.

1. Mineral Buildup in the Showerhead

Over time, hard water minerals like calcium and lime can build up in your showerhead and restrict the water flow. This is especially common in areas with hard water and can cause significant pressure reduction.

Quick Fix: Try soaking your showerhead in a solution of vinegar and water overnight to dissolve the buildup. If the clog is too severe, you may need to replace the showerhead entirely.

2. Clogged or Corroded Pipes

If the issue isn’t your showerhead, the problem could be deeper within your plumbing system. Older homes often have galvanized steel pipes that can corrode or accumulate debris inside, reducing water flow.

Clogged pipes don’t just affect your shower—they can impact water pressure throughout your home.

What to Do: A plumbing inspection can determine if pipe buildup or corrosion is the cause and whether repair or replacement is needed.

3. Faulty Shower Valve

The valve behind your shower handle controls how much hot and cold water is mixed and sent to the showerhead. If the valve becomes worn out or damaged, it may not open fully, which limits water pressure.

Signs to Watch For: Uneven temperatures, weak pressure only on one temperature setting, or difficulty turning the handle.

4. Water Leaks in the Plumbing System

A hidden leak somewhere in your home can reduce the water pressure to fixtures like your shower. Even small leaks reduce the amount of water reaching the showerhead—and can cause significant water damage if left unchecked.

Check for Clues: Higher water bills, damp walls, or the sound of running water when no faucets are on may indicate a leak.

5. Municipal Water Supply Issues or Pressure Regulators

Sometimes the problem is outside your home. If your neighbors are experiencing similar low pressure, there may be an issue with the municipal supply or a water main nearby.

Additionally, if your home has a pressure-reducing valve (PRV), it could be malfunctioning or need adjustment.

Next Steps: A professional plumber can test your home’s water pressure and determine if the PRV or municipal supply is to blame.
