If you need to drain pool water in Glendale, AZ, you are not alone. Many Arizona homeowners face this need every few years. Draining your pool is a necessary part of proper pool care, and doing it correctly makes a big difference.
However, draining a pool is not as simple as opening a valve. There are real risks involved, especially in Arizona’s extreme heat. Therefore, understanding the process before you begin is essential for protecting your pool and your investment.
At Valley Pool Service, we help homeowners across the East Valley handle pool draining safely and professionally. Whether you are in Glendale, Gilbert, Chandler, or Tempe, our team is ready to help you get the job done right.
Why You May Need to Drain Your Pool
Most pools do not need to be fully drained very often. In fact, a full drain is typically only necessary every few years. However, certain situations make it unavoidable.
For example, if your water chemistry becomes severely imbalanced, draining may be the only fix. Additionally, some repairs simply cannot be completed with water in the pool.
Signs Your Pool Needs a Full Drain
There are several clear signs that a full drain may be necessary. First, extremely high cyanuric acid levels are a common reason. Cyanuric acid, also called stabilizer, builds up over time and cannot be removed by adding chemicals alone.
Next, heavy mineral buildup is another strong indicator. Arizona water is notoriously high in calcium and other minerals. As a result, calcium scaling can coat your pool walls and damage your equipment over time.
Also, if you are dealing with a severe algae infestation that has not responded to treatment, a full drain and acid wash may be necessary. Furthermore, resurfacing or replastering always requires a completely empty pool.
- Cyanuric acid levels that are too high to correct with dilution
- Heavy calcium or mineral scaling on walls and tile
- Severe green or black algae that chemicals cannot clear
- Planned pool resurfacing or plaster repairs
- Structural repairs to the shell, steps, or fittings
The Risks of Draining a Pool in Glendale AZ
Draining a pool in Arizona carries unique risks that homeowners should understand. Because of the intense heat and dry soil conditions, problems can develop quickly once the water is removed.
Moreover, improperly draining a pool can cause serious and expensive damage. Knowing the risks ahead of time helps you avoid costly mistakes.
Pool Pop-Out Risk
One of the most serious risks is called pool pop-out, or pool flotation. This happens when an empty pool shell floats upward due to groundwater pressure beneath it. In the Glendale area, this risk depends heavily on soil type and moisture levels.
Therefore, a professional should evaluate your yard and soil conditions before draining begins. Acting quickly and minimizing the time your pool sits empty is also critical.
Sun Damage to Pool Surfaces
Arizona’s sun is extremely harsh. On the other hand, water protects your pool’s plaster, fiberglass, or pebble surface every day. Without water, the surface can crack, blister, or delaminate within just a few hours of direct sun exposure.
Because of this, most pool professionals recommend draining and refilling as quickly as possible. In addition, scheduling this work during cooler morning hours reduces the risk of surface damage.
Equipment and Pump Damage
Your pool pump, filter, and other equipment rely on water flowing through the system to stay cool. Running equipment dry, even briefly, can cause serious damage. Therefore, always shut off all equipment before draining begins.
Additionally, some skimmers and return fittings can crack when the pool shell shifts slightly during a drain. A professional inspection after refilling helps catch any new issues early.
How to Safely Drain a Pool in Glendale AZ
Safe pool draining requires planning, the right equipment, and awareness of local rules. Furthermore, Glendale and other Arizona municipalities have guidelines about where pool water can be discharged. Always check local requirements before draining.
If you are unsure where to start, contact Valley Pool and let our team walk you through the process from start to finish.
Step-by-Step Overview of the Draining Process
First, turn off all pool equipment, including the pump, heater, and any automated systems. Next, connect a submersible pump or use the drain plug at the bottom of your pool to begin removing water.
Then, monitor the water level closely throughout the process. Additionally, check for any signs of soil movement or shifting around the pool shell. Finally, once the pool is empty, complete your repairs or cleaning as quickly as possible before refilling.
- Turn off all pool equipment before starting
- Use a submersible pump for faster, controlled draining
- Discharge water according to local Glendale guidelines
- Work quickly to minimize time the pool sits empty
- Inspect the shell and equipment once drained
- Refill and rebalance water chemistry promptly
Partial Draining as an Alternative
In some cases, a partial drain is all you need. For example, if your cyanuric acid level is only slightly elevated, draining one-third to one-half of the pool and refilling with fresh water may correct the imbalance. Moreover, partial drains are faster, less risky, and easier on your pool’s surface.
However, a partial drain will not solve every problem. Therefore, it is always wise to have a pool professional assess your water chemistry and pool condition before deciding which approach is right for you.
What Happens After You Drain and Refill
Refilling your pool is only half the job. After refilling, your water chemistry will need to be fully tested and balanced. Fresh tap water in the Glendale and greater Phoenix area tends to be high in calcium and minerals. As a result, balancing pH, alkalinity, calcium hardness, and stabilizer is essential right away.
Additionally, your equipment should be restarted carefully and inspected for any air locks or issues caused during the drain. A professional startup inspection after a full drain is always a smart idea.
Post-Drain Water Chemistry Checklist
Once your pool is refilled, test and adjust the following key chemistry levels. First, check and balance pH to keep it in a safe range. Next, adjust total alkalinity, which helps stabilize your pH. Then, test calcium hardness and add a calcium increaser if needed for Arizona’s naturally hard water.
Furthermore, add a fresh dose of stabilizer or cyanuric acid if levels are low after dilution. Finally, shock the pool with chlorine to sanitize the fresh water and prevent early algae growth.
- pH balance
- Total alkalinity
- Calcium hardness
- Cyanuric acid or stabilizer
- Chlorine or sanitizer levels

Frequently Asked Questions About Draining a Pool in Glendale AZ
How often should I drain my pool in Arizona?
Most Arizona pools need a full drain every three to five years. However, this depends on your water quality, usage, and maintenance history. A pool professional can test your water and recommend the right schedule for your specific pool.
Can I drain my pool into the street or alley?
Local rules in Glendale and most Arizona cities restrict where pool water can be discharged. In many cases, discharging directly to the sewer cleanout is required. Therefore, always check with your local municipality or ask a pool professional before draining.
How long does it take to drain a pool?
The time depends on your pool size and the equipment used. However, most residential pools can be drained in several hours with a quality submersible pump. Working quickly is important to reduce exposure of the shell to Arizona’s intense sun.
Is it safe to drain my pool myself?
A partial drain can sometimes be managed by experienced homeowners. On the other hand, a full drain carries real risks, including pool pop-out and surface damage. Because of this, we strongly recommend hiring a licensed pool professional for any full drain in the Glendale area.
What is an acid wash and do I need one after draining?
An acid wash is a deep cleaning treatment applied to pool surfaces after draining. It removes stains, algae, and mineral deposits from the plaster or pebble surface. Additionally, it can restore the appearance of a pool that has been neglected or damaged by severe algae. Not every drained pool needs an acid wash, but it is a great option when surfaces are heavily stained.
