Beat the Frost: Comprehensive Guide to Draining Your Sprinkler System for Winter
What To Know
- A frozen sprinkler system can lead to burst pipes, costly repairs, and a soggy mess come springtime.
- If your sprinkler system has a timer, remove the batteries to prevent it from accidentally activating during the winter.
- Apply warm water to the frozen pipes using a hose or a bucket.
As the chilly winds of winter approach, it’s crucial to protect your outdoor irrigation system from the damaging effects of freezing temperatures. A frozen sprinkler system can lead to burst pipes, costly repairs, and a soggy mess come springtime. To prevent these headaches, it’s essential to drain your sprinkler system before the first freeze.
Step 1: Gather Necessary Tools
Before you start, gather the following tools:
- Screwdriver
- Adjustable wrench
- Garden hose
- Towels or rags
Step 2: Turn Off Water Supply
Locate the water supply valve that controls the flow of water to your sprinkler system. Turn it off completely using the screwdriver or adjustable wrench.
Step 3: Open Drain Valve
Locate the drain valve on the backflow preventer or the lowest point of your sprinkler system. Open the valve fully to allow water to drain.
Step 4: Open Sprinkler Heads
Turn on all the sprinkler heads to release any remaining water from the lines. Keep them open until no more water comes out.
Step 5: Blow Out Sprinkler Lines
Connect one end of the garden hose to the drain valve and the other end to an air compressor. Turn on the air compressor and blow air through the sprinkler lines for about 10 minutes. This will help to remove any residual water and prevent freezing.
Step 6: Close Sprinkler Heads and Drain Valve
Once you’ve blown out the lines, close all the sprinkler heads and the drain valve.
Step 7: Disconnect Garden Hose and Air Compressor
Disconnect the garden hose and air compressor from the system.
Additional Tips
- If your sprinkler system has a timer, remove the batteries to prevent it from accidentally activating during the winter.
- Cover any exposed backflow preventers or sprinkler heads with insulation or foam to protect them from freezing.
- If you have a drip irrigation system, disconnect the lines and store them indoors for the winter.
Signs of a Frozen Sprinkler System
If you suspect your sprinkler system may have frozen, look for the following signs:
- Cracked or burst pipes
- Water leaking from sprinkler heads
- Soggy or waterlogged areas in your yard
If you notice any of these signs, call a licensed plumber immediately to prevent further damage.
Thawing a Frozen Sprinkler System
If your sprinkler system does freeze, do not thaw it using a heat gun or open flame. This can cause serious damage to the pipes. Instead, follow these steps:
- Turn off the water supply and open all the sprinkler heads.
- Apply warm water to the frozen pipes using a hose or a bucket.
- Once the pipes are thawed, close the sprinkler heads and turn on the water supply slowly.
