Resurrect Your Lawn: The Ultimate Guide to Dewinterizing Your Sprinkler System
What To Know
- During winter, water in the sprinkler system can freeze and expand, causing pipes to burst and damage system components.
- Connect the air hose to the air compressor and the other end to the blow-out port on the sprinkler system.
- If you don’t have an air compressor, you can rent one from a hardware store or hire a professional to dewinterize the system for you.
As winter’s icy grip loosens and spring’s warmth beckons, it’s time to revive your dormant sprinkler system. Dewinterizing your sprinkler system is crucial to ensure its efficient operation and prevent costly repairs. This comprehensive guide will empower you with the knowledge and step-by-step instructions to dewinterize your sprinkler system like a pro.
Understanding the Importance of Dewinterizing
During winter, water in the sprinkler system can freeze and expand, causing pipes to burst and damage system components. Dewinterizing removes all water from the system, preventing these costly issues. It also ensures proper water pressure and even distribution when the system is reactivated.
Gathering Essential Tools and Materials
Before embarking on the dewinterizing process, gather the following essential tools and materials:
- Air compressor or air tank
- Air hose with quick-connect fittings
- Adjustable wrench
- Screwdriver
- Bucket or drain hose
- Lubricating oil
Step-by-Step Dewinterizing Instructions
1. Turn Off Water Supply
Locate the main water supply valve for the sprinkler system and turn it off. This will prevent water from entering the system during the dewinterizing process.
2. Open Drain Valves
Identify all drain valves in the system, typically located at the lowest points of the piping. Open these valves to allow water to drain.
3. Blow Out Water with Air Compressor
Connect the air hose to the air compressor and the other end to the blow-out port on the sprinkler system. Turn on the air compressor and allow compressed air to flow through the system. This will force out any remaining water. Continue blowing air until no more water comes out of the drain valves.
4. Disconnect Air Compressor
Once all the water has been blown out, turn off the air compressor and disconnect the air hose.
5. Lubricate System Components
Apply lubricating oil to all moving parts of the sprinkler system, such as valves and sprinkler heads. This will prevent corrosion and ensure smooth operation.
6. Close Drain Valves
After lubrication, close all drain valves securely.
7. Turn On Water Supply
Slowly turn on the main water supply valve and check for any leaks. If no leaks are present, the dewinterizing process is complete.
Additional Tips for Proper Dewinterizing
- If your sprinkler system has a backflow preventer, it’s important to bypass it before blowing out the system.
- Use a bucket or drain hose to collect the drained water and dispose of it properly.
- If you don’t have an air compressor, you can rent one from a hardware store or hire a professional to dewinterize the system for you.
- Consider installing a frost-free sillcock to prevent the backflow preventer from freezing in the future.
Signs of Successful Dewinterizing
- No leaks are present when the water supply is turned on.
- The sprinkler system operates smoothly without any unusual noises.
- Water pressure is consistent throughout the system.
Troubleshooting Common Dewinterizing Issues
1. Water Leaking from the System
- Check for loose connections or damaged pipes.
- Ensure that all drain valves are closed tightly.
- If the leak persists, contact a professional for assistance.
2. Sprinkler Heads Not Popping Up
- Inspect the sprinkler heads for debris or damage.
- Make sure that the water pressure is sufficient.
- If the problem persists, check the valve controlling the sprinklers.
Questions You May Have
Q: How often should I dewinterize my sprinkler system?
A: It’s recommended to dewinterize your sprinkler system every fall before the first hard freeze.
Q: Can I use a garden hose to blow out my sprinkler system?
A: No, a garden hose does not provide enough air pressure to effectively blow out the system.
Q: How much air pressure do I need to dewinterize my sprinkler system?
A: Most sprinkler systems require an air pressure of around 40-60 psi.
Q: What if I don’t dewinterize my sprinkler system?
A: Failing to dewinterize your sprinkler system can lead to burst pipes, damaged valves, and other costly repairs.
Q: Can I dewinterize my sprinkler system myself?
A: Yes, you can dewinterize your sprinkler system yourself with the right tools and knowledge. However, if you’re not comfortable with the process, it’s recommended to hire a professional.
