Winterization season is right around the corner… are you and your customers prepared?
Correctly winterizing your pump is essential—if a step is missed, your pump can sustain damage due to freezing, costing you and your customer valuable time and money. Whether this is your first time winterizing a pump, or your fifth, these easy steps will help walk you through the winterization process, and will leave you feeling confident that your pump will be protected all winter long!
Step 1
Turn off the lawn controller and source water valve—breaking the suction vacuum.
Step 2
If feasible, disconnect the water source and discharge piping.
Step 3
On the pump case, open both top and bottom drain valves to remove water from the pump chambers.
Step 4
If you’re blowing out your irrigation system with pressurized air, use a narrow box wrench to prevent the shaft from spinning. When the impeller spins too fast, the motor governor can be damaged.
Step 5
Once the water is drained from the pump case, close all drain valves.
Step 6
Fill the pump case just past the eye of the impeller with Munro Freeze Defeat pump winterization fluid. This will keep cast iron pump cases from rusting and keep the impeller rust-free for spring start-up.
