Winterizing a Gregson-Clark Sprayer

Winterizing a Gregson-Clark Sprayer

When temperatures fall towards the freezing mark, it is important to properly prepare your sprayer for the winter season. Freezing temperatures can damage vital components of any sprayer if it is not properly winterized. 

In this article, we review steps to winterize a Gregson-Clark Skid and Modular Sprayer. The same steps can be applied to sprayers from different manufactures, but please note that specific parts (such as the strainer) may not be the same. 

What you will need:

- RV antifreeze
- Chemical safety gloves
- Bucket

Step 1:

Begin by removing any remaining spraying solution from the tank. Once all the solution has been removed, partially fill the sprayer with clean water and flush the entire system until empty. 

Step 2: 

Once the system has been drained, place the bucket below the strainer and flush the strainer by removing the yellow plug on the bottom of the lower strainer bowl. Next, loosen the center nut to remove the bottom cup from the strainer, revealing the screen.
Clean the screen and reassemble the filter assembly. Once reassembled, remove the suction hoses from the top and the side of the strainer. Drain and reattach the suction line on the side of the strainer, leaving off the top line to accept antifreeze. 

Step 3:

Fill the strainer with antifreeze and start the system. Check to make sure the regulator is in bypass mode, and continue to add antifreeze into the strainer until antifreeze begins to pump into the tank. Once you have antifreeze flowing into the tank your pump has been winterized. 

Step 4:

In this step we will cover two ways to winterize the hose and reel. One method is to remove the spray hose from regulator that feeds the hose reel and blow it out with forced air. When doing this the spray gun can be removed from the end or you can lock the trigger in the open position. Please note that if you over pressurize the hose, solution may flow back out at you. 

The other option is to run RV antifreeze through the entire system. If you choose to pump antifreeze through the reel, you will need to continue adding antifreeze to the system with the regulator in the "on" position. Cycle through the hose until you have a steady flow of antifreeze spraying at the gun. 

Once you have performed the steps above, your sprayer is ready for cold temperatures. When you are ready to begin using the system, simply flush any remaining antifreeze from the unit and begin operation as normal.
