If you need to drain pool water at your South Scottsdale home, you already know it is not as simple as pulling a plug. Arizona pools face unique challenges that make draining a high-stakes job. Done wrong, it can damage your shell, crack your plaster, or even float your pool out of the ground.
South Scottsdale homeowners deal with intense summer heat, hard water buildup, and rising TDS levels that make draining necessary far more often than in cooler states. Therefore, knowing when to drain — and how to do it safely — is essential knowledge for any pool owner in this area.
At Valley Pool Service, we help homeowners across the East Valley handle pool draining the right way. Whether you are dealing with a green pool, a replaster job, or severely imbalanced water chemistry, our team is ready to help you protect your investment from start to finish.
Why You May Need to Drain Your Pool in South Scottsdale
Not every pool problem requires a full drain. However, some situations simply cannot be fixed with chemicals alone. Knowing the difference can save you time, money, and frustration.
High TDS Levels
TDS stands for Total Dissolved Solids. Over time, minerals, chemicals, and debris build up in your pool water. Eventually, the water becomes so saturated that it resists proper chemical treatment. As a result, balancing your pool becomes nearly impossible without starting fresh.
South Scottsdale’s hard water accelerates TDS buildup. Additionally, the high evaporation rate in Arizona means you constantly top off the pool, adding more minerals each time. Draining and refilling is often the most practical solution.
Severe Algae Blooms
A green pool can sometimes be treated without draining. However, a severe or recurring algae bloom may require a full drain and acid wash. This process removes algae, staining, and buildup directly from the pool surface. Furthermore, it gives your plaster a fresh start and restores the pool’s appearance quickly.
Replastering or Resurfacing
If your pool needs new plaster, pebble finish, or tile work, it must be fully drained first. These structural and cosmetic improvements require a dry, accessible surface. Therefore, a proper drain is the first step in any major pool renovation project.
Equipment Repairs Below the Waterline
Some plumbing repairs, leak fixes, and light replacements require access below the waterline. In those cases, draining the pool is necessary to complete the work safely. Your technician can assess whether a partial or full drain is needed for your specific repair.
The Risks of Draining a Pool in Arizona’s Heat
Arizona heat creates serious risks when draining a pool. Most homeowners do not realize how quickly problems can develop once the water is out. Because of this, timing and method matter enormously.
Pool Shell Damage and Floating
Fiberglass and older plaster pools are especially vulnerable when empty. The shell can crack or delaminate under direct sun exposure. Moreover, if your yard has a high water table — which can occur in parts of the East Valley — hydrostatic pressure can actually push the pool shell upward out of the ground.
This is why draining should never be done carelessly or left unmonitored. A professional team will account for these risks before work begins.
Blistering and Surface Damage
Plaster and exposed pool surfaces bake quickly under Arizona’s intense sun. Even a few hours of direct exposure can cause bubbling, blistering, and surface degradation. Therefore, the draining process must be planned around cooler temperatures and completed efficiently.
Valley Pool Service schedules draining work with Arizona’s climate in mind. We move quickly and carefully to minimize the time your pool surface is exposed to the elements.
Wastewater Disposal Rules
In the Phoenix metro area, including South Scottsdale and nearby communities like Tempe and Mesa, there are local guidelines for where pool water can be discharged. Draining pool water directly into the street or storm drain may violate local ordinances. A professional service will discharge water correctly and in compliance with local regulations.
Additionally, if your pool has been recently treated with high chemical levels, proper disposal is even more important. Valley Pool Service handles this responsibly on every job.
How the Pool Draining Process Works
Understanding the process helps you know what to expect. First, your technician will inspect your pool and equipment before any water is removed. This inspection identifies any structural concerns, evaluates the water chemistry, and determines the appropriate drain method for your situation.
Submersible Pump Method
Most professionals use a submersible pump to remove water efficiently. This method is faster than gravity draining and gives the technician control over the discharge location. Furthermore, it allows for a partial drain if a full drain is not necessary for your specific repair or treatment.
Monitoring Throughout the Process
The technician will monitor the process as water levels drop. This is especially important for older pools and fiberglass shells. Meanwhile, any hydrostatic relief plugs may be opened to prevent pressure buildup beneath the pool shell. This step protects your pool from structural damage during the drain.
Cleaning, Treatment, or Repair
Once the pool is empty, the service work begins. This may include an acid wash, surface repairs, equipment work, or preparation for replastering. After all work is complete, the pool is refilled and the chemistry is balanced from scratch. Finally, your technician will walk you through the new water balance and any follow-up recommendations.

Valley Pool Service proudly serves South Scottsdale and the surrounding East Valley communities. We work regularly in neighborhoods throughout Scottsdale, Tempe, Chandler, and Gilbert. Our team understands the specific pool conditions, water chemistry challenges, and climate factors that affect pools in this region.
South Scottsdale pools, in particular, tend to accumulate calcium and mineral deposits faster than pools in cooler climates. Additionally, older homes in the area often have aging plaster that benefits from periodic draining, acid washing, and replastering to stay in top shape.
If you are unsure whether your pool needs a full drain or just an intensive chemical treatment, our team can assess your pool and give you a clear recommendation. There is no guesswork involved — we inspect, explain, and let you decide. Contact Valley Pool today to schedule your pool assessment and get started.
Tips for South Scottsdale Pool Owners Before and After Draining
Proper preparation makes the draining process smoother and faster. Here are practical tips to help you get ready before your technician arrives.
- Stop adding chemicals at least 24 hours before the drain to reduce chemical concentration in the discharge water.
- Clear the area around the pool deck and equipment pad so the team can work safely and efficiently.
- Note any visible cracks or surface damage you have noticed so your technician can inspect those areas closely.
- Plan for refill time — Arizona pools can take a full day or longer to refill depending on your water pressure and pool size.
- Schedule service in cooler months when possible, such as fall or early spring, to reduce surface exposure risks.
After the pool is refilled, give the water time to circulate fully before swimming. Your technician will balance the chemistry and advise you on when the pool is swim-ready. Furthermore, keeping up with a regular maintenance schedule after a drain will help extend the life of your new surface and equipment.
Frequently Asked Questions About Draining a Pool in South Scottsdale
How often should I drain my pool in Arizona?
Most Arizona pools benefit from a full drain every few years, depending on water quality and TDS levels. Hard water and high evaporation rates in South Scottsdale and the East Valley tend to accelerate mineral buildup. A professional can test your water and recommend the right schedule for your pool.
Can I drain my pool myself?
Technically, yes — but it carries significant risks. Improper draining can crack your shell, damage the plaster, or violate local discharge rules. Therefore, hiring a professional is strongly recommended, especially in Arizona’s extreme heat.
How long does it take to drain a pool?
Draining time depends on pool size and pump capacity. Most residential pools can be drained in a few hours using a submersible pump. However, the full process — including cleaning, repair, and refill — typically takes one to several days depending on the scope of work.
What happens to my pool equipment when the pool is empty?
Your pump and filter should be turned off before draining begins. Running equipment without water can cause serious damage. Your technician will make sure all equipment is safely shut down before removing water from the pool.
Is an acid wash the same as draining?
No — but an acid wash requires a full drain first. An acid wash is a deep cleaning treatment applied directly to the pool surface after the water is removed. It removes stains, algae, and scale buildup from the plaster. Not every pool that is drained needs an acid wash, but many do when algae or staining is present.
