Properly draining your irrigation system is essential to prevent damage caused by freezing temperatures. Failing to winterize your system can result in cracked pipes, damaged sprinkler heads, and costly repairs. To help you protect your investment, Conserva Irrigation of Richmond has put together this comprehensive, step-by-step guide to draining your irrigation system effectively.
Why Draining Your Irrigation System Is Important
- Prevent Freeze Damage
Water left in irrigation lines can freeze and expand, causing pipes to crack and fittings to burst. This can lead to expensive repairs in the spring. - Extend System Lifespan
Proper winterization reduces wear and tear, helping your irrigation system last longer and operate efficiently season after season. - Save on Repair Costs
Preventative maintenance is far less expensive than repairing or replacing damaged components caused by freezing. - Ensure Optimal Performance
A well-maintained irrigation system performs better, conserving water and keeping your landscape healthy.
Types of Draining Methods
- Manual Drain Method
Suitable for systems with manual drain valves, this method allows gravity to do the work. - Automatic Drain Method
Some systems have automatic drain valves that activate when water pressure drops. - Blow-Out Method
The most thorough method, especially for colder climates, involves using an air compressor to force water out of the system.
Step-by-Step Guide to Draining Your Irrigation System
Step 1: Turn Off the Water Supply
- Locate the main water shut-off valve for your irrigation system.
- Turn it off completely to stop water from flowing into the system.
Step 2: Relieve Pressure in the System
- Open any manual drain valves or turn on a sprinkler zone to release built-up pressure.
- This step is crucial to prevent damage when using the blow-out method.
Step 3: Drain the Backflow Preventer
- If your system has a backflow prevention device, follow these steps:
- Turn off the isolation valves.
- Open the test cocks to drain any remaining water.
- Leave the test cocks slightly open for the winter.
Step 4: Manual Drain Method (If Applicable)
- Locate all manual drain valves, typically found at low points in the system.
- Open each valve to allow water to drain out completely.
- Leave the valves open for the winter to prevent trapped water.
Step 5: Automatic Drain Method (If Applicable)
- If your system has automatic drain valves:
- Turn off the water supply and relieve system pressure.
- The automatic valves should open automatically, allowing water to drain.
- Check each valve to ensure it’s functioning correctly.
Step 6: Blow-Out Method (For Complete Drainage)
- Safety First: Wear protective eyewear and follow safety precautions.
- Equipment Needed: An air compressor with a cubic feet per minute (CFM) rating suitable for your system.
Procedure:
- Connect the air compressor to the system’s blow-out port.
- Set the compressor to the recommended pressure (typically 40-60 PSI for PVC pipes; 20-30 PSI for polyethylene pipes).
- Turn on one zone at a time using the irrigation controller.
- Gradually introduce air until water is expelled from the sprinkler heads.
- Turn off the zone and move to the next one.
- Repeat until all zones are drained.
Step 7: Final Checks
- Inspect all sprinkler heads and valves to ensure they’re fully drained.
- Remove any remaining water from hoses and attachments.
- Store irrigation components, such as timers and sensors, in a dry place if removable.
Common Mistakes to Avoid
- Skipping Zones: Ensure every irrigation zone is properly drained to prevent hidden water pockets.
- Using Too Much Air Pressure: Excessive pressure can damage pipes and sprinkler heads. Always follow manufacturer recommendations.
- Forgetting the Backflow Preventer: This critical component is often overlooked but can be costly to repair if damaged.
- Not Checking for Leaks: Before draining, inspect the system for leaks. Addressing issues now prevents bigger problems later.
