Common Cold Weather Well Problems

Cold temperatures can impact several parts of a well system. Here are the most frequent winter-related issues homeowners in Southern Maryland experience:

Frozen Well Pipes

When temperatures drop below freezing for extended periods, exposed or shallow pipes can freeze. This can completely stop water flow—or worse, cause pipes to crack or burst once they thaw.

Frozen Pressure Tanks or Switches

Pressure tanks and switches located in crawl spaces, basements, or well houses without proper insulation are vulnerable in winter. A frozen pressure switch can prevent your pump from turning on at all.

Low or Inconsistent Water Pressure

If water pressure suddenly drops during cold weather, freezing may be restricting water flow somewhere in the system. This is often an early warning sign of a bigger issue.

Well Pump Problems

Extreme cold can strain your well pump, especially if the system isn’t properly protected. In some cases, freezing conditions can lead to pump failure that requires repair or replacement.

Cracked Pipes from Freeze–Thaw Cycles

Even if pipes don’t freeze solid, repeated freezing and thawing can weaken fittings and joints, leading to leaks that may not be immediately visible.

Warning Signs You Shouldn’t Ignore

Have you winterized your well? Cold weather well problems often start small before becoming major repairs. Call for service if you notice:

• No water or water that cuts in and out

• Sudden drops in water pressure

• Strange noises coming from the pump or pressure tank

• Ice buildup near exposed well components

• Water that looks cloudy or discolored after a freeze

Ignoring these signs can lead to more extensive and expensive damage.

What Causes Cold Weather Well Problems?

In Southern Maryland, winter well issues are often caused by a combination of factors:

• Shallow or poorly insulated pipes

• Older well systems are not designed for modern temperature swings

• Well houses or pump rooms without adequate insulation

• Prolonged cold snaps, especially overnight

• Lack of routine maintenance or winter preparation

Even homes that haven’t had issues in past winters can experience problems when temperatures dip below average.

How Homeowners Can Prevent Cold-Weather Well Problems. Winterize your Well System

While not every issue can be prevented, taking a few proactive steps can greatly reduce the risk:

• Insulate exposed pipes and well components

• Seal drafts in well houses or pump enclosures

• Use heat tape where appropriate (installed correctly and safely)

• Keep garage or utility spaces with plumbing above freezing

• Schedule a professional well inspection before winter hits

Preventive maintenance is far less expensive than emergency repairs during a cold snap.

When to Call a Professional Well Service Company

If your water stops flowing, pressure drops suddenly, or you suspect freezing, it’s best to call a professional right away. Attempting DIY fixes—especially improper thawing of pipes—can cause further damage or create safety hazards.

A professional well service technician can quickly diagnose the issue, safely restore water service, and help protect your system from future cold weather well problems.
