As winter arrives, temperatures drop and daylight shortens. When nighttime temperatures fall below 30°F and don’t rebound during the day, freezing becomes a real threat. Ice can quickly form in lines, hoses, and pumps, leading to costly damage and downtime.

To prevent freezing and ice accumulation:

• Warm Up: If there’s any chance of ice in the pump, move your vehicle to a warm area. Allow the water system to thaw entirely before proceeding with maintenance or use.
• Follow Instructions: Always refer to your sewer cleaner’s Operator’s Manual for specific servicing instructions and warnings. Wear eye protection, foot protection, and gloves.

Preventive maintenance is crucial. It not only extends the life of your equipment but also ensures your sewer cleaning gear is always ready.

Importance of Winterizing Equipment

Drain Your System: Empty water tanks, hoses, valves, and plugs after each shift when temperatures are at or below freezing. This prevents burst hoses and damaged gaskets.

Winterization Steps:

• Check Coolant: Ensure it’s rated for extreme winter temperatures to avoid freezing and potential engine block cracks.
• Add Fuel Conditioner: Use it for hydro excavators and vacuum trucks to prevent fuel freezing and aid cold weather starts. Follow the manufacturer’s dosage and compatibility guidelines.
• Inspect Fuel Filter: Clogged filters cause moisture buildup and freezing, leading to poor performance or starting issues. Empty water traps after each shift and keep extra filters handy.
• Use Cold Start Aids: Diesel engines may need ether for cold starts. Check for empty ether bottles or inspect connections on newer systems.
• Set Up Block Heaters: They maintain proper fluid temperature and viscosity, easing engine starts in cold weather. Verify their functionality when temperatures drop.
• Keep Fuel Tank Full: For diesel engines, a full tank prevents condensation and moisture buildup.
• Monthly Starts: If storing equipment like vacuum trucks or hydro excavators, start them at least once a month. Avoid extreme cold; choose a time above freezing.

By following these steps, you safeguard your equipment against winter’s harsh conditions, ensuring they remain in optimal working order.
