Pool Drain & Refill Service
Reset Pool Water That Can No Longer Be Managed Efficiently
Pool water changes over time.
Evaporation leaves minerals behind. Stabilizer can accumulate through repeated use of stabilized chlorine. Calcium hardness can continue rising as Phoenix-area fill water is added. Eventually, maintaining balanced, sanitary water may require increasingly complicated or expensive chemical treatment.
Seader Services evaluates the complete water condition before recommending partial dilution or a full drain and refill.
The goal is not simply to replace the water. It is to determine how much water should be replaced, drain it responsibly, refill the pool promptly and establish a practical new chemistry baseline.
When Water Replacement May Be Appropriate
A partial or complete drain and refill may be recommended when:
Cyanuric acid has accumulated to a level that makes proper chlorine management impractical
Calcium hardness is creating persistent scale-management problems
Multiple chemistry levels cannot be corrected reasonably through normal treatment
Previous chemical use has left the water difficult or expensive to manage
Salt or other dissolved material has accumulated excessively
The pool has undergone contamination that cannot be corrected practically
The existing water must be replaced before approved surface or repair work
A neglected pool would be more responsibly restored through water replacement than repeated chemical treatment
Not every older pool needs new water, and not every chemistry problem requires a complete drain.

Partial Drain or Complete Drain?
A full drain is not automatically the best answer.
Depending on the test results, replacing only part of the water may reduce calcium hardness, stabilizer, salt or other accumulated material enough to restore manageable conditions.
Before recommending a complete drain, we consider:
Current calcium hardness
Current cyanuric acid
Salt level when applicable
pH and total alkalinity
Pool volume
Finish type and visible condition
Severity of scale or staining
Refill-water chemistry
How much dilution is needed
Whether partial replacement can achieve the intended result
Weather and refill timing
This diagnosis-first process helps avoid replacing more water than necessary.
What the Service May Include
A standard drain-and-refill project may include:
Complete pre-service water testing
Estimating pool volume and required water replacement
Reviewing the visible condition of the pool finish
Determining whether partial or complete replacement is appropriate
Identifying the intended discharge route
Shutting down circulation equipment and the automatic fill system
Draining with a professional submersible pump
Monitoring the discharge and accessible drainage area
Removing ordinary loose debris from the pool floor
Beginning the refill promptly after draining
Restarting circulation after the water reaches the proper level
Testing the new water
Establishing initial sanitizer, pH, alkalinity and stabilizer levels
Inspecting visible equipment operation after restart
Providing post-service findings and care instructions
Stain removal, acid washing, chlorine washing, heavy debris removal, surface repair and equipment repair are separate services unless specifically included in the proposal.
When Your Filter May Need Cleaning
Filter cleaning may be appropriate when:
Pressure rises approximately 8–10 PSI above the clean baseline
Return flow becomes noticeably weaker
The filter’s service history is unknown
Water clarity begins to decline
The pool recently experienced algae or heavy debris
The filter becomes dirty shortly after backwashing
The pump appears to be working harder than normal
The pressure gauge remains elevated
Circulation problems develop despite normal pump operation
The filter has not been opened and inspected recently
Pressure should be evaluated alongside water flow and pump speed. On variable-speed systems, pressure readings should be compared at the same RPM because changing pump speed also changes filter pressure.
Our Drain-and-Refill Process
Here’s What To Expect:
1. We Test the Existing Water
We evaluate the chemistry problem and determine whether water replacement is justified.
2. Review the Pool and Timing
We consider the finish, visible condition, weather, access, refill supply and how long the pool is expected to remain empty.
3. Determine the Replacement Amount
We recommend partial dilution or a full drain based on the intended chemistry outcome.
4. Confirm the Discharge Plan
The discharge route must comply with the rules governing the property’s municipality and sewer system.
5. Drain and Monitor the Pool
A submersible pump is used to remove the approved volume of water while the discharge area is monitored.
6. Refill Promptly
Once draining and any approved empty-pool work are complete, the refill begins. The water should run continuously until the pool reaches the proper operating level.
7. Restart and Establish the New Baseline
We restart circulation when appropriate, test the refill water and make the initial balancing adjustments.
Responsible Pool-Water Discharge
Pool water cannot simply be pumped into the street.
For properties within the City of Phoenix, pool water normally must be directed to the property’s sanitary-sewer cleanout or retained on the property under appropriate conditions. It may not be discharged into a street, alley or storm drain without specific authorization. The City also instructs users to monitor the home for sewer backup as draining begins.
Requirements can differ by municipality, property type, sewer connection and water condition. The discharge route will be discussed before service begins.
If a usable sanitary-sewer cleanout cannot be located, is blocked or cannot safely accept the discharge, plumbing assistance or municipal authorization may be required before the pool can be drained.
Timing Matters
A pool should not remain empty longer than reasonably necessary
Before scheduling, we consider:
Current and forecast weather
Pool-finish condition
Refill-water availability
Drain and refill duration
Other work planned while the pool is empty
Property access
Municipal billing periods
Whether the project can be completed without unnecessary surface exposure
Pool-finish manufacturers advise homeowners to consult a qualified pool professional before draining because exposing the finish can create risks that are not present while the pool is full.
Urgent water replacement may still be possible, but timing and surface concerns should be discussed first.
Phoenix Sewer-Billing Note
City of Phoenix residential sewer charges are recalculated using water consumption during the January through March billing cycles. A large pool refill during that period can affect the calculation.
Phoenix allows homeowners to request a Sewer Fee Review for qualifying pool fills during those months. Keep the service invoice and pool-volume information if the project occurs during a January, February or March billing cycle.
Customers served by another municipality should review that utility’s billing and adjustment policies because the calculation periods and procedures may differ.
What a Drain and Refill Does Not
Automatically Fix
Replacing the water can correct dilution-dependent chemistry problems, but it does not by itself repair:
Surface stains
Scaling attached to the pool finish
Etching or damaged plaster
Cracks or structural movement
Algae embedded in poorly maintained surfaces
Damaged filters
Circulation problems
Leaking plumbing
Failing pumps or equipment
Contamination sources that remain after refill
If another condition must be addressed before or during the project, it will be explained separately.
Pricing
Standard residential drain-and-refill projects generally begin around $399.
Final pricing may depend on:
Pool volume
Partial versus complete drainage
Access to the pool and equipment
Distance to the approved discharge point
Drainage limitations
Debris in the empty pool
Existing chemistry
Refill-water chemistry
Startup chemical requirements
Additional visits
Surface or equipment concerns
Other work requested while the pool is empty
The property owner’s municipal water charges are not included in the service price.
Specialty cleaning, stain treatment, acid washing, chlorine washing, repairs and replacement parts are quoted separately.
Frequently Asked Questions
Q: How often should a pool be drained and refilled?
There is no responsible universal schedule. Water should be replaced when testing and operating conditions show that dilution is necessary—not simply because another year has passed.
Q: Does the entire pool always need to be drained?
No. Partial water replacement may be enough to lower calcium hardness, stabilizer, salt or other accumulated material. We calculate the likely dilution before recommending a full drain.
Q: What is the best time of year?
Cooler conditions often provide more flexibility, but the best timing depends on the pool finish, weather, urgency, refill availability and municipal billing considerations.
Q: How long will the project take?
Timing depends on pool size, discharge rate and refill-water pressure. The project normally extends across the drain and refill period rather than a single brief appointment. We provide a more specific expectation after evaluating the property.
Q: Can I turn the refill water off overnight?
The refill should generally continue without interruption until the pool reaches its proper level. Stopping midway can contribute to visible waterlines or uneven exposure on some finishes.
Q: Will draining remove pool stains?
Not by itself. Draining exposes the surface so certain separately approved treatments can be performed, but fresh water alone does not remove most stains or scale.
Q: Does a green pool need to be drained?
Not necessarily. Many green pools can be recovered through debris removal, filtration, brushing and properly managed treatment. We recommend water replacement only when the complete condition justifies it.
Q: Can the old water be pumped into the street?
Generally not. Phoenix prohibits ordinary pool drainage into streets, alleys and storm drains and directs pool water to the sanitary-sewer cleanout or another authorized route. Other municipalities have their own requirements.
Q: Do I need to be home?
Usually not for the entire process, provided access, discharge arrangements and the refill-water source are confirmed. Someone must be reachable in case a drainage, sewer or refill issue develops.
