The Definitive Guide On How To Drain An Intex Pool Safely And Efficiently
Draining an Intex pool involves utilizing the integrated dual-drain system or a submersible pump to remove water while preventing hydrostatic pressure damage to your lawn or property. Success requires coordinating the discharge hose placement with local municipal drainage codes and ensuring the liner remains stable throughout the rapid volume reduction process.
Essential Preparation and Operational Prerequisites
Before initiating the drainage process, you must evaluate the volume of water relative to your drainage point to avoid localized flooding or surface erosion. Intex pools, ranging from small Easy Set models to large Ultra Frame units, can contain thousands of gallons; discharging this volume indiscriminately can damage peripheral landscaping or foundation soil.
- Essential Equipment:
- Standard garden hose (non-kinking).
- Intex drain valve adapter (typically included with the pool; if missing, a standard threaded adapter is required).
- Submersible pump (optional, but highly recommended for pools over 1,500 gallons to reduce time).
- Plumbers tape or silicone O-rings to ensure a leak-proof seal at the valve.
- Safety and Environmental Standards:
- Water chemistry check: Ensure pH levels are between 7.2 and 7.8 and chlorine levels are near zero before discharging into storm drains or grass to protect local aquatic ecosystems.
- Site evaluation: Identify the lowest elevation point on your property or a designated sewer clean-out access.
- Time Benchmark: A gravity-fed drain can take 8 to 24 hours depending on head pressure and hose diameter, whereas a 1/4 HP submersible pump can reduce the time to under 3 hours.
Executing the Drainage Workflow: A Systematic Approach
Step 1: Neutralizing and Preparing the Water
Before movement begins, ensure the water is free of high concentrations of sanitizers. If the pool has been recently shocked, wait at least 48 to 72 hours until the chlorine dissipates to undetectable levels. High chemical concentrations can destroy turf and violate local EPA guidelines regarding storm water runoff.
Step 2: Attaching the Drainage Assembly
Locate the drain valve on the exterior wall of the pool liner near the base. Remove the outer plug and screw the included adapter onto the threaded fitting. As you tighten, ensure the internal gasket is seated correctly; failing to seat this gasket will result in significant leakage during the connection phase. Connect your garden hose to the adapter.
Step 3: Positioning the Discharge Line
Route your hose to a safe drainage area, such as a storm drain, a dry well, or a sloped area of your yard that can absorb high volumes of water.
Warning: Never discharge water directly against the foundation of a home or into a septic system, as the high volume can overwhelm leach fields and cause catastrophic basement flooding or structural shifting.
Step 4: Activating the Drain
Once the hose is securely positioned, push the adapter inward to open the internal valve. If your model uses a screw-on cap, unscrew the cap to initiate gravity flow. For faster drainage, place a submersible pump at the bottom center of the pool, ensuring the pump is fully submerged, and run the discharge hose over the top rail of the pool.
Step 5: Managing the Liner and Final Cleanup
As the water level drops below 6 inches, the weight of the water will begin to shift. Monitor the liner to ensure it folds inward evenly rather than collapsing into a heap of debris. Once gravity flow stops, use a wet-vac or a siphon hose to remove the final remaining puddles to prevent algae growth or mosquito breeding on the pool floor.

Technical Specifications and Drainage Methodology Comparison
| Feature | Gravity Drain Method | Submersible Pump Method |
|---|---|---|
| Efficiency | Low (8–24 hours) | High (1–4 hours) |
| Equipment Cost | Minimal (Included) | Moderate ($60–$120) |
| Effort Level | Low (Set and forget) | Moderate (Active monitoring) |
| Debris Handling | Poor (Clogs valves) | High (Handles small silt) |
| Suitability | Small pools/Maintenance | Large pools/Winterizing |
Common Site Failures and Field Fixes
- Root Cause: The drain valve is stuck or clogged.
- Actionable Fix: Use a blunt probe (like a plastic stirring rod) to gently clear debris from the internal valve seat. If the valve itself is frozen, apply a small amount of silicone-based lubricant to the threads.
- Root Cause: Water is not flowing even when the valve is open.
- Actionable Fix: Check the hose for kinks or airlocks. If the drainage site is higher than the base of the pool, gravity will not function; you must elevate the pool or use a pump to push the water over the obstruction.
- Root Cause: The pool liner is collapsing or bulging during drainage.
- Actionable Fix: Stop the drainage process immediately. The liner is likely under tension due to uneven ground. Smooth out the floor folds manually as the water recedes to ensure the liner doesn't trap water pockets or tear under its own weight.
Frequently Asked Questions
Can I use a regular garden hose to drain my Intex pool?
Yes, most Intex pools come with a threaded drain valve specifically designed to accept a standard 5/8-inch or 3/4-inch garden hose. Ensure the hose is free of kinks, as the low pressure of gravity drainage requires a clear, unobstructed path for water to exit effectively.
How do I drain the final few inches of water that the valve misses?
Since the drainage valve is located slightly above the base, it will always leave a residual layer of water. Use a submersible utility pump placed at the lowest point of the pool, or use a manual siphon hose to pull the remaining water over the side wall.
Is it safe to drain the pool water into my backyard?
It is safe if the water is free of chemicals and the soil is capable of absorbing the volume. Do not discharge on sloped land that leads to your home's foundation, and check local ordinances, as some municipalities prohibit discharging pool water into the street or storm drains during specific seasons.
How often should I fully drain an Intex pool?
You typically do not need to drain your pool every season unless you are changing the liner or moving the pool location. With proper chemical maintenance, a pool can run for several years before a full water replacement is necessary to balance Total Dissolved Solids (TDS).
