🚿 Is Your Shower Losing Pressure? Here’s What It Could Mean

😩 Tired of a Weak Shower?

There’s nothing worse than stepping into the shower after a long day—only to be greeted by a sad drizzle of water. Low water pressure is one of the most common plumbing complaints we hear from homeowners across Cambridge, and while it might feel like a minor inconvenience, it can actually point to bigger issues in your plumbing system.



In this blog, we’ll break down the common causes of low water pressure, what you can do about it, and when to call in the pros at Reliant Plumbing.

🔎 What Causes Low Water Pressure?

Low pressure can show up in one faucet, multiple fixtures, or your whole house. Pinpointing the source helps determine whether it's an easy fix—or something more serious.

1. 🪠 Clogged Showerhead or Faucet Aerator

Over time, mineral deposits from Cambridge’s hard water build up inside your fixtures, especially showerheads.

🔧 The Fix:

• Unscrew the showerhead
• Soak it in vinegar overnight
• Scrub gently and reinstall

If this fixes the issue—great! If not, read on.

2. 🧪 Hard Water Buildup in Pipes

Cambridge has very hard water. Over time, calcium and magnesium deposits can narrow your water lines, especially in older copper or galvanized steel pipes.

🚩 Signs:

• Gradual loss of pressure over time
• More than one fixture is affected
• You’ve had hard water issues before

🔧 The Fix:

• Reliant Plumbing can inspect your lines with cameras or flow tests
• Pipe replacement or descaling may be needed
• A water softener can prevent future buildup

3. 🪛 Partially Closed Shutoff Valve

A partially closed main shutoff or fixture-specific valve will restrict water flow.

🔧 Check:

• Your home’s main shutoff valve (usually in the basement or near the water meter)
• The angle stop valve under the affected sink or fixture

Make sure they’re fully open.

4. 🚿 Faulty Pressure Regulator

Some homes in Cambridge—especially in newer subdivisions—have a pressure-reducing valve (PRV) installed. If it fails, your pressure can drop suddenly.

🔧 The Fix:

PRVs should be tested and replaced by a licensed plumber. If yours is faulty, we can install a reliable, long-lasting replacement.

5. 💧 Leaks in Your Plumbing System

Leaks can reduce pressure by diverting water away from your fixtures.

🚩 Signs:

• Sudden pressure drop
• Damp spots on walls or floors
• Spinning water meter with no water running

🔧 The Fix:
Call Reliant Plumbing for a leak detection service. We use non-invasive tools to find and fix hidden leaks fast.

6. 🏙️ Municipal Water Supply Issues

Sometimes, the issue isn’t in your home at all. If pressure is low throughout the neighbourhood, the city may be performing maintenance or upgrades.

📞 Tip: Call the City of Cambridge or check their website for updates on local water line work.

🧼 Why Shower Pressure Matters

Low pressure isn’t just annoying—it can impact:
