Expert Pool Draining & Drain Services in Phoenix
Safe, Professional Pool Draining When You Need It
While pools are designed to stay filled with water, certain maintenance tasks, repairs, and restoration services require complete or partial draining. Whether you need your pool drained for acid washing, plaster repair, equipment replacement, deep cleaning, or inspection, proper draining technique is critical to prevent structural damage and ensure safe refilling. At McCool's Pools, we've safely drained hundreds of pools throughout the Phoenix area since 2005. We understand Arizona's unique challenges—high groundwater tables in some areas, extreme temperature fluctuations, and local regulations regarding water disposal. Our experienced team ensures your pool is drained correctly, safely, and in compliance with all local requirements.
When Your Pool Needs Professional Draining
Acid Wash or Deep Cleaning
The most common reason for draining a pool is to perform an acid wash or thorough deep cleaning. These surface restoration services require complete access to all pool surfaces, which is only possible when the pool is empty. Acid washing removes years of staining, scaling, and buildup, dramatically improving your pool's appearance. The draining process is the critical first step that enables this transformation.
Plaster or Surface Repairs
Significant plaster repairs, resurfacing, or tile work require a dry work environment. Whether you're addressing cracks, delamination, staining that can't be removed with acid washing, or you're ready for complete replastering, proper draining is essential. The pool must be drained carefully to prevent additional damage during the emptying process and to ensure surfaces are ready for repair work.
Major Equipment Replacement or Upgrades
Some equipment installations or replacements require lowering the water level or complete draining. Main drain replacement or repair, in-floor cleaning system work, light niche repairs, and certain plumbing modifications all necessitate draining. We coordinate equipment work with the draining process to minimize downtime and ensure proper installation.
Leak Detection and Structural Inspection
When leaks are suspected but can't be pinpointed with the pool filled, draining allows thorough visual inspection of all surfaces. Cracks in plaster, separation around fittings, compromised structural elements, and hidden leaks become visible once the water is removed. This diagnostic draining often reveals problems that would otherwise remain mysterious and expensive.
Extreme Water Chemistry Problems
Occasionally, water chemistry becomes so severely imbalanced that draining and refilling is more cost-effective than trying to correct it chemically. Extremely high total dissolved solids, severe cyanuric acid buildup, or contamination from flooding or other sources sometimes necessitate starting fresh with new water. While this is relatively rare, it's sometimes the best solution for getting your pool back to proper chemical balance.

The Risks of Improper Pool Draining
Structural Damage from Hydrostatic Pressure
The most serious risk of draining a pool is hydrostatic pressure damage. When groundwater levels are high, an empty pool can actually float or pop out of the ground like a boat. This can crack the pool structure, break plumbing lines, damage decking, and require extremely expensive repairs. Professional pool draining includes assessment of groundwater conditions and use of hydrostatic relief valves when necessary to prevent this catastrophic damage.
Surface Cracking from Temperature Extremes
Phoenix's intense summer heat can cause rapid drying and temperature extremes in empty pools. Plaster exposed to direct sunlight can crack, shrink, or develop problems that weren't present before draining. Professional draining services time the work appropriately, protect exposed surfaces when necessary, and minimize the time the pool remains empty to prevent heat-related damage.
Plumbing and Equipment Damage
Improper draining procedures can damage pool equipment, crack plumbing lines, or create problems with valves and fittings. Running a pump dry, draining too quickly, or failing to protect equipment during the process leads to expensive repairs. Our team follows proper procedures to protect all pool systems throughout the draining process.
Improper Water Disposal
Pool water disposal is regulated in many Phoenix-area jurisdictions. Draining thousands of gallons into storm drains, streets, or in ways that cause property damage or environmental problems can result in fines and liability issues. We ensure all water disposal complies with local regulations and doesn't create problems for you or your neighbors.
Our Professional Pool Draining Process
Pre-Drain Assessment and Planning
Before any draining begins, we assess your specific situation. We evaluate groundwater conditions in your area and check weather forecasts to ensure appropriate timing. We identify the reason for draining and coordinate with any other work being performed. We plan proper water disposal routes and methods. We verify that your pool structure is suitable for safe draining. This planning prevents problems and ensures the work proceeds smoothly.
Proper Equipment Setup
We use appropriate pumps and equipment for efficient, controlled draining. Submersible pumps are positioned correctly to remove water without damaging pool surfaces. Discharge hoses are routed to approved disposal locations. Hydrostatic relief valves are opened when groundwater conditions require. All equipment is monitored throughout the draining process to ensure safe operation.
Controlled Draining Rate
Pools shouldn't be drained as quickly as possible—controlled draining at appropriate rates prevents structural stress and allows monitoring for any developing problems. We drain at speeds that are safe for your pool's structure and local groundwater conditions. If issues arise during draining, our controlled approach allows us to stop and address problems before they become serious.
Continuous Monitoring
Throughout the draining process, we monitor for signs of problems—bulging walls, cracking plaster, equipment issues, or water disposal concerns. This vigilance catches developing issues early when they can be addressed before causing serious damage. We don't just set up pumps and walk away—we actively manage the entire draining process.
Post-Drain Inspection and Protection
Once draining is complete, we inspect the empty pool for any issues that need attention. We document the condition for you and for any contractors performing subsequent work. If the pool will remain empty for any time, we take appropriate measures to protect surfaces from sun damage and prevent safety hazards. We coordinate the timing of refilling to minimize the pool's time spent empty.
Professional Refilling and Startup
When work is complete and it's time to refill, we manage that process as carefully as we managed draining. Water is added at controlled rates to prevent surface damage. We monitor for leaks or problems as the pool fills. Once filled, we begin the process of balancing chemistry and preparing the pool for use. We don't consider the job complete until your pool is full, balanced, and ready for swimming.
Drain Service Options
Complete Pool Draining
Full draining removes all water from the pool, providing complete access to all surfaces and allowing the most thorough work. This is required for acid washing, replastering, major repairs, and thorough inspections. We coordinate complete draining with whatever service necessitates the empty pool, minimizing the time your pool is out of service.
Partial Draining for Equipment Work
Some maintenance and repair work only requires lowering the water level rather than complete draining. Light replacement, skimmer repairs, and certain plumbing work can often be accomplished with the pool still partially filled. This approach saves time, reduces water waste, and gets your pool back in service more quickly. We assess what level of draining your specific situation requires.
Emergency Draining Services
Occasionally, emergency situations require rapid pool draining—severe contamination, structural concerns, or damage that makes keeping the pool filled dangerous or problematic. We provide emergency draining services when time is critical, working quickly while still maintaining safety protocols and proper procedures.
Coordination with Other Services
Pool draining is often just one component of a larger project—acid washing, equipment installation, plaster repair, or renovation work. We coordinate draining with all related services to ensure efficient scheduling and minimal disruption. Whether we're performing all the work or draining for another contractor, we manage the process professionally and communicate clearly with all parties involved.

Common Pool Draining Questions
How long does it take to drain a pool?
Draining time depends on your pool's size and the pumping equipment used. A typical residential pool takes 8-12 hours to drain completely using appropriate professional pumps. We never rush the draining process—controlled draining at safe rates is more important than speed. We'll provide a realistic timeline when we assess your specific situation.
Can I drain my pool myself?
While it's physically possible to drain your own pool, we strongly recommend against it. The risks of structural damage from hydrostatic pressure, improper water disposal violations, equipment damage, and safety hazards make DIY draining a potentially expensive mistake. Professional draining costs far less than repairing the damage that improper draining can cause. This is definitely a job for experienced professionals.
When is the best time to drain my pool?
In Phoenix, spring and fall are generally the best seasons for pool draining. Avoid summer when extreme heat can damage exposed plaster, and avoid winter monsoon season when groundwater levels may be elevated. We also consider immediate weather forecasts, current groundwater conditions, and your specific circumstances to recommend optimal timing for your draining.
How often should pools be drained?
Most pools don't need regular draining unless specific issues arise. Pools typically require draining for acid washing every 5-7 years, for replastering every 10-15 years, or when repairs or equipment replacement necessitate it. Draining just for the sake of draining isn't beneficial and subjects your pool to unnecessary risk. We recommend draining only when there's a legitimate reason for the service.
What happens to the water?
Pool water disposal depends on local regulations and your specific situation. In many Phoenix-area locations, water can be discharged to the sanitary sewer system through a cleanout. Some properties can drain to landscaping if doing so doesn't create runoff or drainage problems. Street and storm drain disposal is often prohibited. We ensure disposal complies with your local jurisdiction's requirements.
Will draining damage my pool?
When performed correctly by experienced professionals, draining doesn't damage pools. The risks—hydrostatic pressure, heat exposure, structural stress—are all managed through proper procedures, appropriate timing, and continuous monitoring. This is why professional draining is so important. We've drained hundreds of pools without causing damage because we understand and manage the risks involved.
