Outdoor Irrigation Systems:Cold Weather Preparation
Cold weather can mean frozen water lines. As water expands when it freezes, homeowners must do all they can to reduce the risk of sprinkler line rupture. If you have an outdoor irrigation system, promptly servicing those lines can save you a great deal of mess and expense. Protect your Minneapolis lawn with the help of a sprinkler professional.
Turn off water at the source
The first step in shutting down your irrigation system for the winter may be as easy as turning off the water to the lines. However, you will also need to take steps to protect the connections and valves at the source. Any water remaining at or near the shut-off valve could freeze and risk rupturing the connections. Even slow leaks can do damage to the sill plate of your home and create rot, inviting in pests that can do even more damage.
You may also need to disconnect the lines at the source, so water in the lines can be blown out. Be aware that, since the first frost of the year comes early in the Minneapolis area, there may already be pressure in the lines. Don't disconnect them on your own unless you're ready to handle any back pressure. The experts at Growing Environments can help you determine the safest and tidiest way to disconnect the lines.
Drain the lines
The irrigation lines under your lawn may run for several yards. Blowing them out may require a large compressor or another tool to safely move water out of the lines. If you don't have the right tools, things could get messy. Reach out to Barrett Lawn Care for help to clear out your lines completely.
Guard valves and backflow tools
Depending on the distance your irrigation system covers, there may be several valves and backflow preventers far from your home. Proper water expulsion is critical to keeping these devices in good shape.
Letting your irrigation lines freeze may lead to leaks at any of these connectors. Frozen lines can also split along the length of the pipes. Early cleanout is a critical first step in protecting your irrigation system from a breakdown.
How to know if you have a leak
When it's time to start your irrigation system in the spring, carefully review its functionality so that you can look for leaks. These leaks may present the following problems:
A decrease in the distance covered by your sprinklers
Standing water
Muddy or sunken spots in your lawn
Sloppy wet and marshy patches of lawn can be difficult to mow. They can also provide a haven for mosquitoes.
Do your best to address your outdoor irrigation system before the first frost. Once it's done, you can enjoy the beautiful fall colors without worrying! Look for more yard maintenance tips from The Home Mag on Facebook and Instagram.
