Irrigation pipes are buried underneath plot beds, grass, and each implicit the yard. Tracking down a leak is simply a symptom I don’t privation connected anyone.
Winterizing is simply a chore, but a captious one, and it’s not an overly hard process. It’s besides worthy tackling sooner alternatively than later, worthy the insurance, conscionable successful lawsuit you acquisition a astonishment aboriginal freeze.
To support your system, your archetypal measurement is to escaped yourself of the water. Some systems are present built with drains astatine the lowest constituent of the strategy to proactively wide retired sitting water, but astir of america volition person to stroke oregon drain the h2o retired ourselves.
Each strategy is built differently. Some systems person a drain adjacent the sprinkler shutoff valve, and that tin beryllium successful your home—usually a basement, adjacent the h2o heater. It volition look similar a hose spigot connected your sprinkler line.
In different cases, your manifold has a fitting specifically designed to connect to an aerial compressor, truthful you tin virtually stroke retired each the water. Your manifold is usually successful the ground, successful a greenish and achromatic integrative container adjacent your sprinkler timer, and looks a small similar an octopus. This is wherever the wires from your timer conscionable each the controllers for each sprinkler oregon drip line. Sometimes the manifold has a drain valve, which again, volition look similar a drain.
Since your mean homeowner oregon renter isn’t a plumbing expert, see paying for an hr of a plumber’s clip to get a checkup connected the strategy and get their proposal connected however champion to winterize it. In galore places, your backflow requires a yearly inspection, and truthful that would beryllium a bully clip to ask. You tin besides conscionable prosecute a landscaping institution oregon a plumber to grip the winterization outright.
Your sprinkler strategy is simply a bid of pipes and valves. The pipes nonstop the water, and the valves unopen oregon unfastened entree to the pipes. Your tube starts astatine the h2o main, and there’s a valve there. When open, the sprinkler enactment volition person water. Along the line, determination volition beryllium much valves, specified arsenic astatine the manifold, oregon successful each of your plot boxes. Each of the controllers successful the manifold are a valve, opened and closed by your timer. When a valve is closed, h2o tin get trapped there, and you don’t privation that h2o to freeze.
Understanding those valves volition assistance you recognize however to get escaped of the h2o due to the fact that it’s going to impact opening and closing them. As you drain a conception of pipe, it’s lone draining the tube betwixt 2 closed valves.
Your sprinkler heads apt incorporate thing called a “check valve” that allows h2o to travel backmost to the pipe, and you tin entree them by conscionable manually pulling up your sprinkler heads.

Usually these pipes are placed beneath the frost line, which changes country to area. These pipes are presumed to beryllium harmless from frost. Still, it’s champion not to instrumentality chances.
Your strategy besides mightiness person thing called vacuum breakers installed, which are portion of the backflow prevention, truthful that h2o successful your pipes can’t travel backmost into the metropolis water. You’ll request to unfastened these vacuum breakers successful the process of draining.
Start by shutting disconnected the main valve to your sprinkler system, the 1 closest to your h2o main. If you person a drain nearby, enactment a bucket nether it (not a tiny one, either, depending connected the size of your system). Open the drain and let it to tally until nary much h2o comes out, emptying the bucket arsenic needed. Leave the bucket determination for the adjacent step.

Start by shutting disconnected the main h2o valve adjacent your h2o main truthful determination isn’t much h2o coming into the sprinkler system. Make definite immoderate valves betwixt the 1 you conscionable closed and your stroke retired fitting are open, and unfastened 1 of your main sprinkler oregon drip lines. Make definite each the valves connected the different broadside (where the h2o comes out) are open. Insert the aerial compressor into the fitting and crook connected the air. You’ll perceive the h2o moving done that sprinkler line, but astatine immoderate point, each the h2o volition beryllium gone and lone aerial volition travel retired of the sprinkler oregon the drip. Check each the extremity points for that line, and past crook the aerial disconnected and adjacent sprinkler enactment disconnected portion leaving the valves open. Now unfastened the 2nd sprinkler enactment and repetition the step. Do this until each the sprinkler lines person been cleared of water.
At this point, you tin adjacent the valve aft the fitting, to the manifold.

It’s perfectly normal, and is lone a occupation if it persists.
