One day, I needed to drain a large puddle from my yard after a rainstorm, and I realized that using a garden hose to siphon the water was the simplest solution. Siphoning water with a garden hose is a handy skill for many situations, like emptying a pool, draining a flooded area, or moving water from one container to another. The process uses basic physics, relying on gravity to move the water once it gets flowing.

Here’s an easy step-by-step guide on how to siphon water using a garden hose, no pump required!
Tools You’ll Need:
- Garden hose (of sufficient length to reach both the water source and the drainage area)
- Water source (the area or container you want to drain)
- Bucket (optional, for priming the hose if needed)
- Gloves (optional, to keep your hands dry)
Step-by-Step Instructions for Siphoning Water
1. Prepare the Garden Hose
- Inspect the hose for any kinks, holes, or blockages. Ensure it’s in good condition to create a proper siphon.
- Check the length: Make sure the hose is long enough to reach from the water source to the area where you want to drain the water.
2. Position the Hose
- Submerge one end of the hose completely in the water source. This end must stay submerged to create the siphon.
- The other end of the hose should be placed at a lower level than the water source. Siphoning works by gravity, so the outlet end needs to be below the water level for the flow to work properly.
Tip: The more elevation difference between the water source and the drainage point, the faster the siphon will flow.
3. Fill the Hose with Water to Prime It
To start the siphon, you need to fill the hose with water to eliminate any air pockets. There are two common methods to do this:
Method 1: Submerge the Entire Hose
- Submerge the entire hose into the water source until it fills with water. Make sure all air is out of the hose.
- Once the hose is full of water, cover one end of the hose with your thumb to create a seal. Pull the hose out of the water and quickly move it to the drainage area. Release your thumb, and water should start flowing.
Method 2: Using a Faucet (Faster Method)
- Attach the hose to a faucet or outdoor spigot, and run water through the hose until it’s completely full.
- Disconnect the hose from the faucet, making sure water remains in the hose, and quickly place the free end in the drainage area.
- Water should begin to flow immediately once the pressure equalizes and gravity takes over.
4. Start the Siphon (Without Using Your Mouth)
- Place the outlet end of the hose where you want the water to drain (lower than the water source).
- If water isn’t flowing, gently shake or wiggle the hose to remove any trapped air pockets. This will help establish the siphon.
5. Monitor the Flow
Once the siphon is working, water will continue to flow through the hose until the water level in the source drops below the hose’s intake or until you lift the hose above the water source.
Tip: If the water flow slows down or stops, check for kinks or blockages in the hose.
Alternative Method: Siphon Using Your Mouth (If Comfortable)
If you don’t mind using your mouth to start the siphon, here’s how you can do it safely:
- Submerge one end of the hose in the water.
- Suck on the other end to draw water into the hose.
- As soon as water reaches your end, quickly place it in the drainage area and let gravity take over. Be careful not to swallow any water, especially if it’s dirty or unsafe.
Troubleshooting Common Issues
- Water Flow Stops: Check if the outlet end of the hose has been raised above the water source. This can break the siphon.
- Air Bubbles: If air enters the hose, the siphon will stop. Shake the hose or restart the process to remove air.
- Weak Flow: Ensure the height difference between the water source and the drainage area is significant enough to allow gravity to do its job.
Final Thoughts
Siphoning water with a garden hose is a simple and effective way to transfer water using gravity alone. By following these easy steps and using either the submersion or faucet method to prime the hose, you’ll be able to drain or move water efficiently without needing pumps or complicated equipment. Just remember to keep the hose lower than the water source and ensure there are no air pockets for a smooth flow.
