Winterizing your Drip Irrigation System
Being proactive when it comes to winterizing your drip irrigation system can save a lot of time and money in repairs later. It is is not as overwhelming as it appears. Here are 3 easy to follow steps.
- Turn water source off and remove timer and head assembly (backflow preventer, filter and pressure regulator) from water source. Drain and store these components indoors where they will never be exposed to freezing temperatures.
- Open all end caps to allow any excess water to flow out. We recommend that you walk your mainlines and lift lines and fittings at any low spots. This will help in removing any excess water and aid in flowing out the open ends. While tubing might survive a bit of freezing, fittings will crack if standing water is left to freeze in them.
- Once you are sure that all excess water has been removed from your mainlines you can replace the caps. We also recommend that you place a cap on the threaded end of the female swivel adapter. (This is the one component left from the head assembly) Doing this will keep bugs and dirt from entering your system through the winter.
If your main water source is a manifold system steps 2 and 3 will be the same but you will want to start by using your shut off valve to turn all water off to the manifold. If no shut valve exists, you may want to consider adding one. Open all valves. This will reduce the chance of standing water freezing and cracking your manifold components.
In most cases the above steps will get the job done. However many of our customers also like to use an air compressor. Air pressure and water pressure are very different, we recommend that you always have the ends of the line open and always use your hand as a coupler between the poly tubing and the nozzle of the air compressor. By following these simple rules, it will help to ensure that you do not damage your system with too much air pressure.
