Emptying a swimming pool is a common requirement for pool maintenance, repairs, winterization, or replacement. While the easiest and most efficient method involves using a pool pump, not everyone has access to one — whether due to cost, availability, or equipment failure.
If you’re in a situation where you need to drain your pool without a traditional pump, don’t worry. There are several practical, alternative methods that can help you get the job done — though it may take a bit more time and effort. In this article, we’ll explore how to empty a swimming pool without a pump using accessible tools and techniques, while emphasizing safety, efficiency, and legal compliance.
Why You Might Need to Drain a Pool
Before diving into the how-to, it’s important to understand why you might need to empty your pool completely:
Common Reasons for Draining a Pool
- Major repairs: To fix leaks, cracks, or plumbing issues
- Winterization: In some climates, pools need to be fully drained to avoid freeze damage
- Reline or resurfacing: For structural or aesthetic upgrades like installing a new liner
- Contamination: When water is heavily contaminated with chemicals or debris
- Replacement: If you’re removing the existing pool entirely
Each of these scenarios may require a complete drain — and if you don’t own a pump, it’s time to get creative.
Key Considerations Before Draining
Before you start the process, make sure you understand the logistics and legal implications of emptying your pool:
Environmental and Local Ordinance Compliance
Do not drain pool water onto your lawn or sewer system without checking local laws. Chlorinated water is toxic to plants, wildlife, and your municipal sewer system. In many jurisdictions, you’re required to dechlorinate water or discharge it into a storm drain or public sewer with permission.
Structural Risks of an Empty Pool
Draining an in-ground pool can be risky — the water pressure from the surrounding ground can push the pool structure upward if the pool isn’t designed to handle an empty state. Some inground pools must remain partially filled for structural integrity.
Pro tip: Always consult the manufacturer or a trained pool technician before fully draining an inground pool.
What You’ll Need
These are some common tools and supplies that may come into play:
- Garden hoses (50–100 feet length)
- Buckets or large containers
- Siphon hose or vacuum hose
- Water testing kit
- Dechlorination chemicals (like sodium thiosulfate)
- A helper (for safety and efficiency)
Now that you’re prepared with important safety and legal considerations, let’s move into the actual methods of how to empty a pool without a pump.
Method 1: Manual Bucketing (Best for Small Pools or Spas)
While it may seem old-fashioned, using buckets is a reliable way to empty a small pool — especially above-ground pools or hot tubs.
Step-by-Step Guide:
- Test the water for chlorine and pH levels.
- Dechlorinate the water if necessary.
- Choose an outlet (drainage ditch, lawn, or sewer access) that’s approved for disposal.
- Use large buckets or containers to scoop and pour the water out.
- Work with a partner to speed up the process — one filling, one dumping.
This method, while slow, requires nothing more than manual labor and persistence. A 500-gallon hot tub could be emptied in a few hours, but this is not recommended for large pools due to the time and effort involved.
Estimated Time for Manual Draining:
For a standard 8’ x 15’ above-ground pool (about 5,000 gallons), expect about 6 to 8 hours of continuous effort by a team of two people using large buckets and a wheelbarrow system.
Method 2: Using a Siphon Hose (Best for Moderate-Sized Pools)
Siphoning is one of the most effective non-pump solutions. The trick relies on gravity and a simple setup involving a garden hose.
How a Siphon Works
Siphoning creates a vacuum that pulls water from a higher level (the pool) to a lower level (drainage point). You’ll need to ensure the discharge end is at least a couple of feet lower than the starting point.
Step-by-Step Guide to Siphoning a Pool:
- Secure access to a hose long enough to reach the drainage area (e.g., 100-foot hose).
- Fill the hose with water completely (you can submerge it in the pool or use a tap).
- Seal both ends while lifting the hose to avoid losing the water inside.
- Place one end in the pool (as low as possible) and the other at the drainage point.
- Release the ends simultaneously — water will begin to flow via gravity, creating a siphon.
This process can be assisted by starting with a small flow using your mouth (avoid swallowing), or more safely by using a pump to start the siphon temporarily.
Enhancing the Siphon Effect
- Use a hose that’s at least 1 inch in diameter for better water flow.
- Ensure the discharge end flows outward unobstructed (avoid sharp turns).
- To keep the siphon going nonstop, secure the hose in place and leave it unattended (if safe to do so).
Tips:
- Use weighted objects to keep the hose end submerged in the pool.
- Check for kinks or air blockage regularly.
For a 10,000-gallon inground pool, this method will take roughly 24–48 hours, depending on hose size and elevation difference.
Method 3: Using a Wet/Dry Vac (Best for Partial Draining)
A wet vacuum can be an efficient tool, particularly when targeting partial drainage. While it won’t fully empty a large pool, it can be useful for removing stagnant water in skimmer areas, vacuum lines, or just a few inches of water after siphoning.
Important: Always check that your vacuum is rated for continuous water use and has a heat protection system to avoid motor failure.
How to Use a Wet Vac to Drain Pool Water:
- Dechlorinate the water first to protect your equipment.
- Place the vacuum near the lowest point of water accumulation.
- Vacuum slowly, ensuring the hose doesn’t get submerged too deeply or too shallow.
- Empty the vacuum tank frequently to keep the process flowing.
This is most effective in tandem with one of the other methods like a siphon, to get as much water out as possible before using the vacuum to finish the job.
Pros and Cons of Using a Wet Vac:
| Pros | Cons |
|---|---|
| Fast for small amounts of water | Limited to small water volumes |
| Effective for residual or standing water | May overheat if run for extended periods |
Method 4: Gravity-Assisted Drainage Using a Pool Spillover Valve
Some older pools and models are built with drain valves, especially inground pools. If your pool has a hydrostatic valve (also known as a spillover valve), you may be able to remove the plug and let gravity assist the draining process.
To Use a Spillover Drain Valve:
- Locate the valve — consult your pool’s manual if unsure of its location.
- Ensure a clear drainage path is available (i.e., not leading into your basement).
- Open the valve carefully and let gravity pull the water downward.
This is one of the most passive methods, though it doesn’t apply to all pools — and the water flow rate can be relatively slow.
When a Spillover Valve Might Not Be Enough
- If the surrounding ground water level is high, you risk inflow unless the valve has a check mechanism.
- Valves often can’t empty a pool fully — they leave behind a few inches of water.
- Regular checks and cleanings are required to avoid sediment clogging.
Combining Methods for Faster Results
The best approach is to combine methods to enhance the overall speed and efficiency. Here’s an example:
Hybrid Drainage Method:
- Begin draining with a siphon hose for 6–12 hours to make a major dent.
- Use buckets or a wet vac to remove residual water from deep areas.
- Finish by using a spillover valve if available, to deal with the last bit of water.
This staged combination ensures you’re using your most powerful method first (siphoning), then leveraging tools like buckets and vacuums for the hard-to-drain areas.
Estimated Draining Times by Pool Size
| Pool Type | Approximate Gallons | Siphon Time Estimate | Bucketing Time Estimate (2 People) |
|---|---|---|---|
| Small above-ground pool | 5,000 | 10–12 hours | 5–6 hours |
| Mid-sized inground pool | 15,000 | 24–30 hours | 16–20 hours |
| Large luxury pool | 30,000 | 48–60 hours | 30–36 hours |
By combining methods, you can reduce the workload significantly.
Environmental and Safety Tips
When handling pool water manually, it’s critical to follow best practices:
Dispose of Water Responsibly
- Dechlorinate water using a chemical neutralizer before draining.
- Don’t discharge water into storm drains unless permitted — always check with local waste management guidelines.
- Avoid runoff to neighbor’s properties or nearby streams.
Minimize Soil Erosion Risk
If draining onto your lawn, spread out the flow over a large area to avoid erosion. You can also use sandbags or trenches to guide water safely.
Avoid Electric Risks
Make sure all power to the pool equipment is turned off before starting. Avoid using electrical devices near standing water unless properly grounded.
Water Test Kit Checklist:
| Chemical | Safe Discharge Range | Neutralizer |
|---|---|---|
| Chlorine | < 0.1 ppm | Sodium thiosulfate |
| pH | 6.5 – 8.0 | Adjust with pH+ or pH- |
| Alkalinity | 20–200 ppm | Dilution or acid adjustment |
Using a test kit ensures your drainage complies with local standards and avoids penalties or ecological harm.
When to Call a Professional
Sometimes, it’s safer and more efficient to hire help, especially when:
- You’re dealing with an inground pool that may require structural support or backfill.
- You’re not familiar with local water discharge laws and risk fine or penalty.
- You need the pool drained urgently (e.g., repair work or emergency maintenance).
Professionals bring portable pumps, dechlorination systems, and expertise in safe and legal draining practices. While it may cost a few hundred dollars, it’s worth the peace of mind and better long-term care.

Can I empty a swimming pool without a pump?
Yes, it is entirely possible to empty a swimming pool without using a pump. While pumps offer a fast and efficient way to remove water, alternative methods can be used when a pump is not available. These techniques require tools commonly found around the home, such as hoses and buckets, and rely on principles like gravity or siphoning to move water out of the pool. Though these methods may take more time and effort compared to using a pump, they are effective and cost-efficient for smaller pools or partial draining.
One popular option is using a siphon system created with a garden hose. By submerging the hose completely in the pool and then sealing the ends, you can create a flow of water that exits the pool once one end of the hose is placed lower than the water level outside. Consistent water flow is achieved as gravity pulls the water downward. This technique is best performed with two people and can take longer than mechanical draining methods, but it’s a viable solution if no pump is available.
Is it safe to drain a swimming pool completely without a pump?
Draining a swimming pool completely without a pump can be safe as long as proper precautions are taken. However, caution must be exercised depending on the type of pool you own. In-ground pools, for example, can be vulnerable to structural damage if the surrounding groundwater level is high. Without water inside to balance the pressure, the empty pool might shift or crack. Be sure to consult the manufacturer’s guidelines or a pool professional before fully draining an in-ground pool.
Additionally, you must always direct the water away from your home’s foundation, decks, or neighboring properties to avoid flooding or erosion issues. If you’re using a siphoning method to empty the pool completely, check that the drainage location is appropriate and compliant with local regulations. For above-ground pools, while structural concerns are less severe, make sure the pool is stable and that the liner is not damaged during the process.
How long does it take to empty a pool without a pump?
The time required to empty a swimming pool without a pump varies depending on several factors including the size of the pool, the method used, and the water flow rate. For example, a small above-ground pool might be emptied in a matter of a few hours using a siphon hose. However, a larger in-ground pool could take several hours or even an entire day, depending on the diameter of the hose and the distance over which the water must travel.
Using a standard garden hose siphoning method, it’s common to expect about 10 to 15 gallons per minute, depending on the setup and elevation differences. As a result, removing 10,000 gallons of water could easily take over 10 hours. The task can be accelerated by using multiple hoses simultaneously or by using larger diameter hoses designed for water transfer. However, be prepared to spend significant time monitoring the process and refilling the hose to maintain continuous flow.
Will using a siphon damage my swimming pool?
Using a siphon is generally a safe method for removing pool water and does not cause damage when done correctly. Since it does not involve mechanical pumps or high-pressure equipment, the risk of introducing stress to the pool structure is minimal. Just make sure the hose is smooth and free of damages that could leak or disrupt the siphon. Also, avoid dragging the hose over rough surfaces or sharp pool edges, which might scratch or wear down the pool lining or surface.
That said, improper drainage during and after the siphoning process can lead to complications. If you are draining the pool near sensitive areas such as landscaping or foundations, consider that the large volume of water may erode the soil or cause flooding. If you’re using buckets or other manual methods, be careful not to drop heavy objects into the pool or scratch it while scooping out water. Always maintain awareness of the surroundings to avoid both pool damage and property damage while draining.
Where should I drain the pool water?
When emptying a swimming pool without a pump, it is crucial to choose a proper location for draining the water to prevent damage or legal issues. Ideally, the water should be discharged into a designated drainage area, storm drain, or onto open ground that can absorb water without eroding nearby structures. Avoid letting the water flow into neighboring yards, public sidewalks, or areas where it might pool and create slipping hazards.
Make sure the water from the pool is free of harmful chemicals before discharging, especially if you are releasing it into municipal sewer systems or environmentally sensitive areas. Some localities require you to dechlorinate the water before release. Always check with local authorities to make sure your drainage plan complies with municipal codes and environmental standards to avoid penalties or unintended harm.
What tools do I need to empty a pool without a pump?
To empty a swimming pool without a pump, you will need a few basic tools: a long, durable garden hose, preferably without leaks, and a large bucket or container if you’re using a manual method. Some people prefer having two people to help prime the hose. Additionally, you may need a weight or object to anchor the hose underwater, and possibly a funnel to assist in starting the siphon. For safety, a pair of gloves and eye protection may be useful during hose setup or water removal.
Optional tools include a plastic float (like a pool noodle) to keep the hose from sinking entirely to the bottom, allowing sediment to be left behind. A siphon starter device or a wet/dry vacuum may also help jump-start the process. If removing water manually with buckets, consider having multiple people work together to save time and effort. Lastly, ensure proper placement of the hose outlet to allow smooth drainage of all the water you remove from the pool.
How do I start a siphon without a pump?
To start a siphon manually and begin draining your pool without a pump, you’ll first need to ensure your hose is clean and leak-free. Fully submerge the entire hose in the pool so it fills completely with water, holding both ends under the water’s surface. Once filled, block one end with your thumb or a plug and quickly place it at the desired drainage site — lower than the pool’s water level — while keeping the other end inside the pool.
Another method involves creating suction by mouth on one end of the hose — though this is not recommended if the water may contain harmful chemicals. A more effective alternative is using a vacuum to prime the suction: place one end of the hose into the pool and insert the other end of the hose into a wet/dry vacuum. Start the vacuum to remove air from the hose; once water begins flowing into the vacuum, quickly move the hose end to the drainage area. Once properly positioned, continuous flow should be maintained as gravity pulls the water out of the pool.
