Why Your Water Pressure Is Low—and How to Fix It

Common Causes of Low Water Pressure in Florida (And What to Do About It)

Low water pressure is more than just an annoyance—it can be a warning sign of hidden plumbing problems. If you’ve noticed weak flow at your faucets or slow-filling appliances, here are the most common reasons it happens in Florida homes—and how to fix it.

1. Mineral Buildup from Hard Water

Florida has some of the hardest water in the country, meaning it’s full of minerals like calcium and magnesium. Over time, these minerals accumulate inside pipes and fixtures, restricting water flow.

Signs of hard water buildup:

• White, chalky residue on faucets and showerheads
• Reduced flow even when the main water valve is fully open
• Appliances like dishwashers and washing machines taking longer to fill

Solution: Installing a whole-home water softener can prevent future buildup, and descaling affected fixtures can restore flow.

2. Partially Closed or Faulty Shut-Off Valves

Sometimes the cause is as simple as a valve that isn’t fully open. Your home has two main shut-off points:

• Main shut-off valve (usually near the water meter)
• Meter valve (owned by the water company)

If either is partially closed—whether from recent work or accidental bumping—it can restrict pressure throughout your home.

Solution: Ensure both valves are completely open. If the meter valve is the issue, contact your water provider.

3. Clogged or Corroded Pipes

Older Florida homes may have galvanized steel pipes that corrode from the inside out. Even copper and PEX systems can develop clogs from sediment, rust, or debris.

Warning signs:

• Gradual pressure loss over time
• Discolored or rusty water
• Low pressure in specific areas of the home

Solution: Pipe replacement or professional cleaning, depending on severity.

4. Municipal Water Supply Issues

Sometimes the problem isn’t in your home at all. Local water utilities may lower pressure temporarily for maintenance or because of high seasonal demand.

Solution: Contact your water provider to check for outages or maintenance work in your area.

5. Leaks in Your Plumbing System

Even a small hidden leak can divert water flow and lower pressure. In Florida’s humid climate, leaks can also lead to mold growth and structural damage.

Signs of a leak:

• Unexplained increase in your water bill
• Wet spots on walls, ceilings, or floors
• Sound of running water when fixtures are off

Solution: Schedule a leak detection service immediately to pinpoint and repair the problem.

6. Water Pressure Regulator Problems

Some homes have a pressure regulator on the main water line. If it fails, it can cause either excessively high or very low water pressure.

Solution: Have a plumber test and, if needed, replace the regulator.

How to Test Your Water Pressure

You can check your home’s water pressure with a pressure gauge (available at hardware stores). Attach it to an outdoor spigot and turn the water on fully.

• Normal range: 40–60 PSI
• Low pressure: Below 40 PSI
• High pressure: Above 80 PSI (can damage plumbing)

If your reading is low, it’s time to troubleshoot using the causes above—or call Flamingo Plumbing for a professional diagnosis.

Why Florida Homeowners Should Act Fast

Low water pressure isn’t just an inconvenience—it can be a symptom of bigger plumbing problems. In Florida, where hard water, aging pipes, and heavy rain can stress your plumbing, ignoring low pressure can lead to:

• Burst pipes from hidden corrosion
• Costly water damage
• Reduced appliance lifespan
• Increased utility bills
