Frozen Grinder Pump? Here’s What to Do Before Calling for Repair

If your grinder pump is frozen or your grinder pump alarm is sounding in freezing weather, you’re not alone. Winter temperatures in Clifton Park, Saratoga, Albany, Mayfield, and the Capital Region can cause grinder pumps and basins to freeze, leading to alarms, slow drainage, and potential backups.

This situation requires immediate attention, but what you do next matters. Taking the wrong steps can make the problem worse, cause permanent system damage, and increase repair costs.

Below is exactly what to do if your grinder pump freezes, based on what our technicians handle every winter.

First, Don’t Panic

A frozen grinder pump does not automatically mean catastrophic failure. However, it does need prompt attention to prevent damage and backup.

What NOT to Do with a Frozen Grinder Pump

Homeowners sometimes try to “defrost” the pump themselves. This is dangerous and ineffective. You should call a professional service immediately to prevent any further damage and to get instructions on what to do for your situation.

Do NOT Ignore the Problem 

A grinder pump alarm or freeze issue needs attention. Ignoring it can result in:

• Sewage backup into the home or yard
• Burst pipes
• Permanent pump failure
• Significant repair expenses

Immediate action reduces damage and costs.

What You CAN Safely Do Before Calling a Professional

You Can Silence the Alarm

Most grinder pump alarms include a silence or mute function. Silencing the alarm does not shut down the pump. It simply quiets the alert while the issue is addressed. The warning light will often remain on, that is normal.

Reduce Water Usage OR Cease Water Usage

Minimize water consumption while waiting for service. Limit:

• Laundry
• Long showers
• Dishwashers
• Excessive flushing
• Reducing flow decreases pressure and stress on the systems

Call a Professional Immediately

Frozen grinder pumps are not a DIY project. Proper service ensures:

• Safe thawing methods
• Protection of electrical components
• Prevention of additional damage
• Correct diagnosis
• Faster restoration of service
