Expert Solutions for Water Pressure Issues in San Antonio, TX

Common Causes of Low Water Pressure

Low water pressure can be frustrating, especially when it affects your showers, sinks, or appliances. If your faucets trickle instead of flow, or your washing machine takes longer than usual to fill, there may be an underlying issue that needs professional attention. Here are some of the most common reasons homeowners experience low water pressure:

• Pipe Buildup & Corrosion: Over time, mineral deposits and rust can accumulate inside your pipes, reducing the diameter and restricting water flow.
• Hidden Leaks: A leak in your plumbing system can cause a drop in pressure as water escapes before reaching your fixtures.
• Municipal Water Supply Issues: Sometimes, the problem isn’t inside your home—local water line maintenance or a drop in city water pressure can impact your supply.
• Pressure Regulator Malfunctions: If your home has a pressure regulator, a faulty one can cause inconsistent or weak water pressure.
• Partially Closed Main Shutoff Valve: If your home’s main water valve isn’t fully open, it can restrict flow and lead to lower pressure.

Regardless of the cause, our team at Lujan Plumbing can quickly identify the source of your low water pressure problem and provide effective solutions.

What Causes High Water Pressure?

While low water pressure is an inconvenience, high water pressure can be just as problematic—if not worse. Excessive pressure can strain your pipes, leading to leaks, burst pipes, and damage to your appliances. Here are some of the main culprits behind high water pressure:

• Faulty Pressure Regulator: If your home has a pressure regulator and it’s failing, your water pressure may spike beyond safe levels.
• City Water Pressure is Too High: Some neighborhoods receive high-pressure water from the municipal supply, which can be too strong for household plumbing.
• Thermal Expansion: When water heats up inside a closed plumbing system, it expands and increases pressure, which can lead to stress on pipes.

If you suspect that your water pressure is too high, our experienced plumbers can test it and install or adjust a pressure regulator to protect your plumbing system.

Signs You Need Water Pressure Repair

Not sure if your home’s water pressure is at the correct level? Here are some signs that indicate a need for professional assessment and repair:

• Drastically weak or slow water flow from faucets or showerheads
• Inconsistent water pressure that fluctuates between strong and weak
• Banging or loud noises from pipes (a sign of high pressure issues)
• Leaking pipes or frequent plumbing issues due to excessive pressure
• Appliances like dishwashers or washing machines not filling properly

If you’re experiencing any of these problems, it’s essential to get your water pressure checked before it leads to costly repairs or pipe damage.

Frequently Asked Questions About Water Pressure

What is the ideal water pressure for a home?

The recommended residential water pressure range is between 40-60 psi (pounds per square inch). Anything above 80 psi can cause damage, while anything below 30 psi may lead to weak water flow.

Can low water pressure be fixed?

Yes! Once we identify the cause—whether it’s clogged pipes, leaks, or a faulty regulator—we can make the necessary repairs to restore normal pressure.

How do I know if my water pressure is too high?

Signs of high water pressure include banging pipes (water hammer), leaking faucets, and appliances wearing out faster than expected. A pressure gauge can measure your home’s psi levels.

Do I need a pressure regulator?

If your home experiences frequent fluctuations or high water pressure, installing a pressure regulator can protect your pipes and appliances.
