Quick Answer
To winterize your shallow well jet pump, you'll need to drain the system, replace the antifreeze with water, and then fill the pipes with compressed air to prevent damage from freezing temperatures. This process typically takes around 1-2 hours to complete. Properly winterizing your jet pump will ensure it functions correctly when you need it.
Section 1: Draining the System
Draining the system is the first step in winterizing your shallow well jet pump. Start by locating the drain valve at the base of the well casing and opening it to allow any remaining water to escape. This will typically take around 30 minutes to an hour, depending on the size of the system. Once the flow of water slows to a trickle, close the drain valve to prevent any further water from entering the system.
Section 2: Replacing Antifreeze with Water and Filling with Compressed Air
After draining the system, replace the antifreeze with water by opening the pump’s suction valve and allowing the system to fill with fresh water. Use a submersible pump or a hose with a high flow rate to fill the pipes as quickly as possible. Once the system is filled with water, use a compressor to fill the pipes with compressed air. This will help to displace any remaining water and prevent damage from freezing temperatures. Typically, you’ll want to fill the pipes to around 10-15 PSI to ensure they remain pressurized throughout the winter months.
Section 3: Testing the System
After winterizing your shallow well jet pump, it’s essential to test the system to ensure it’s functioning correctly. Start by checking the pump’s suction valve to ensure it’s closed and the system is pressurized. Next, turn on the pump and check for any signs of leaks or excessive pressure. If everything seems in order, you can rest assured that your jet pump is ready for the winter months ahead.
