If you need to drain pool water in Tempe, AZ, you are not alone. Many homeowners across the East Valley reach a point where a simple chemical treatment just will not do the job. Sometimes a full or partial drain is the safest and most effective solution.
Draining a pool is not always a straightforward task. In fact, it comes with real risks if it is not handled correctly. Therefore, working with an experienced local pool service team makes a big difference for your pool and your property.
At Valley Pool Service, we help homeowners in Tempe, Gilbert, Chandler, and Mesa keep their pools clean, safe, and swim-ready. Our technicians understand Arizona pool conditions and know exactly when and how to drain a pool the right way.
Why You Might Need to Drain Your Pool
There are several common situations that call for a pool drain. First, high total dissolved solids (TDS) can build up over time. TDS refers to the accumulated minerals, chemicals, and organic matter that cannot be filtered out. When TDS levels climb too high, your water becomes difficult to balance and can damage your equipment.
Additionally, a severe algae infestation sometimes requires a full drain and scrub. Chemical treatments work well in many cases. However, some algae blooms go too far and respond better to a fresh start.
Other Common Reasons to Drain a Pool
- Replastering or resurfacing – The pool must be empty before any surface work begins.
- Structural repairs – Cracks, tile replacement, or coping repairs often require a dry pool.
- Extreme water chemistry imbalance – When cyanuric acid or calcium hardness is too far out of range, draining is often the fastest fix.
- Seasonal deep cleaning – Some homeowners prefer to start fresh every few years with a full drain and acid wash.
Because Arizona pools are used year-round, TDS levels tend to rise faster here than in cooler climates. For example, our intense summer heat accelerates evaporation, which concentrates minerals in the water. As a result, Tempe pool owners may need to drain more frequently than homeowners in other states.
The Risks of Draining a Pool Incorrectly
Draining a pool without proper knowledge can cause serious damage. Furthermore, local regulations in Tempe and across Maricopa County require that pool water be discharged properly. You cannot simply pump pool water into the street or a neighbor’s yard.
Hydrostatic Pressure and Pool Pop-Up
One of the biggest risks is called hydrostatic pressure. This is the pressure that groundwater creates beneath your pool shell. When a pool is empty, that underground pressure can literally push the shell up out of the ground. This is sometimes called a pool “pop-up,” and it is a costly problem to fix.
Therefore, timing matters. In Arizona, the water table is generally lower, which reduces this risk. However, it is still a real concern in certain neighborhoods, especially near the Salt River or in areas with irrigation-heavy landscaping. A professional will assess your site before draining begins.
Sun Damage to Pool Surfaces
An empty pool exposed to the Arizona sun can suffer surface damage quickly. Plaster and fiberglass are especially vulnerable. Direct sunlight causes cracking, blistering, and discoloration when a pool sits dry for too long. Moreover, the heat radiating off an empty pool shell can cause the surrounding deck to expand and shift.
For this reason, professionals work quickly once a pool is drained. They schedule the drain, cleaning, repairs, and refill to minimize the time the pool sits empty under the hot Arizona sun.
How Valley Pool Service Drains Pools in Tempe
Our process is thorough and efficient. First, we inspect your pool and equipment before we begin. We check for any structural concerns, review your water chemistry, and confirm the best discharge method for your property.
Next, we use a submersible pump to remove the water at a controlled rate. We always follow Tempe and Maricopa County discharge guidelines. In many cases, we direct the water to your sewer cleanout, which is the safest and most compliant method available.
What Happens After the Pool Is Drained
Once the pool is empty, our team gets to work. We inspect the shell for cracks, stains, and surface damage. Then, we perform any necessary cleaning, including pressure washing or acid washing if the surface requires it.
An acid wash removes deep stains, algae residue, and mineral deposits from the plaster. It is a strong treatment, so we only recommend it when truly necessary. After the work is complete, we refill the pool and carefully balance the water chemistry before you swim.

Partial Drains vs. Full Drains
Not every situation calls for a full drain. In many cases, a partial drain is enough to solve the problem. For example, if your cyanuric acid level is slightly elevated, draining and replacing a portion of the water can bring it back into range quickly.
A partial drain is faster, less risky, and easier on your pool shell. Additionally, it uses less fresh water, which matters in a desert climate like Arizona. On the other hand, a full drain is necessary for resurfacing, major repairs, or severe water quality problems that a partial drain cannot correct.
How to Know Which Option You Need
The best way to determine the right approach is a professional water test and pool inspection. Our technicians will test your water, evaluate your equipment, and give you a clear recommendation. We always explain your options and the pros and cons of each before any work begins.
If you are unsure what your pool needs, talk with a pool care expert on our team. We service pools throughout Tempe, Gilbert, Mesa, Chandler, and the surrounding East Valley communities.
Tempe Pool Draining and Local Regulations
Tempe homeowners must follow specific rules when draining a pool. The City of Tempe, like most Arizona municipalities, restricts where pool water can be discharged. Chlorinated water can harm local plants, soil, and the municipal stormwater system.
Because of this, the preferred discharge method is the sanitary sewer. Most homes have a sewer cleanout access point that allows pool water to drain safely into the wastewater system. Our team is familiar with local requirements and always follows proper procedures.
Furthermore, we dechlorinate the water when required before discharge. This protects your landscaping and keeps you in compliance with local ordinances. When you hire Valley Pool Service, you never have to worry about fines or violations.
Tips for Tempe Homeowners Before a Pool Drain
There are a few things you can do to prepare before your drain service appointment. These steps will help the process go smoothly and protect your property.
- Clear the area around the pool – Remove furniture, toys, and loose items from the deck.
- Locate your sewer cleanout – Ask our team if you are unsure where it is located.
- Avoid running your pump dry – Do not operate your pool pump once the water level drops below the skimmer.
- Plan for a short turnaround – The pool should not sit empty for more than a day or two in Arizona heat.
- Communicate any recent repairs – Let our technicians know about any recent work done on the shell or plumbing.
Moreover, plan to be home or available during the drain if possible. Our team will walk you through what we find and what we recommend as we go.
Frequently Asked Questions About Draining a Pool in Tempe
How often should I drain my pool in Arizona?
Most Arizona pools benefit from a partial drain every one to two years. A full drain is typically needed every five to seven years, depending on usage and water quality. However, your specific pool may need service sooner if your TDS or calcium levels become unmanageable.
Can I drain my pool myself in Tempe?
Technically, yes. However, it is not recommended without experience. Improper draining can damage your pool shell, violate local discharge rules, or harm your equipment. A professional service ensures the job is done safely and in compliance with local regulations.
How long does it take to drain and refill a pool?
The draining process typically takes several hours, depending on pool size. Refilling can take a full day or more with standard water pressure. Our team plans the schedule carefully to minimize the time your pool sits empty in the Arizona heat.
What is an acid wash, and do I need one?
An acid wash is a deep cleaning treatment applied to the pool surface after draining. It removes stains, algae, and mineral buildup. Not every pool needs one. Our technicians will inspect the surface and recommend an acid wash only when it is truly necessary.
