Lake Nona Pool Maintenance

Pool Drain and Refill Services in Lake Nona

Pool drain and refill is a specialized service segment within the broader Lake Nona pool maintenance sector, involving the controlled removal of pool water, inspection or treatment of the exposed shell, and reintroduction of fresh water to restore safe chemical balance. The process carries structural, chemical, and regulatory dimensions that distinguish it from routine maintenance tasks. Understanding how this service is classified, when it is warranted, and what standards govern it is essential for property owners, HOA managers, and licensed pool contractors operating in the Lake Nona area.

Definition and scope

A pool drain and refill service encompasses the complete or partial removal of water from a residential or commercial swimming pool, spa, or water feature, followed by a structured refill sequence. The service is distinct from spot treatments, filter backwashing, or partial dilution top-offs, each of which addresses water chemistry without fully evacuating the vessel.

Florida pool contractors performing drain and refill work operate under licensing requirements administered by the Florida Department of Business and Professional Regulation (DBPR) under Florida Statute Chapter 489, Part II. A Certified Pool/Spa Contractor (CPC) license is the credential class applicable to this category of work. Unlicensed pool drainage that involves structural access, plumbing manipulation, or chemical discharge may constitute a violation of Chapter 489 or applicable local ordinances.

Geographic scope and coverage limitations: This page covers pool drain and refill services within Lake Nona, a master-planned community located within the southeastern corridor of Orange County, Florida. All regulatory references apply to Orange County jurisdiction and applicable Florida state statutes. Properties in adjacent areas — including Osceola County communities near Narcoossee Road, St. Cloud, or unincorporated Kissimmee — are not covered by this page and may be subject to different local ordinances or utility policies. Water discharge regulations, permit requirements, and inspection protocols discussed here do not apply outside Orange County unless otherwise noted.

How it works

A complete pool drain and refill proceeds through four discrete phases:

  1. Pre-drain assessment — A licensed contractor evaluates water chemistry, shell condition, and hydrostatic pressure risk. Pools built over high water tables — common in Central Florida's low-elevation terrain — face risk of "floating," where groundwater pressure beneath an empty shell can lift or crack the structure. Orange County's water table levels vary seasonally, making this assessment particularly critical between June and September during the Florida rainy season.

  2. Drainage execution — Water is discharged using submersible pumps routed to a sanitary sewer cleanout or other approved discharge point. The Orange County Utilities division governs discharge into the municipal sewer system; discharging directly to stormwater drains, streets, or natural waterways may violate Florida Department of Environmental Protection (FDEP) rules under Chapter 62-620, Florida Administrative Code.

  3. Shell inspection and treatment — With the pool empty, contractors inspect plaster, tile, coping, and fittings for damage. This phase often overlaps with pool resurfacing or pool tile and coping care services when deterioration is identified. Acid washing to remove calcium scale or staining is also performed at this stage if warranted.

  4. Refill and chemical startup — Fresh water is introduced via a fill hose, and a startup chemical protocol is applied over 24–72 hours to reach balanced parameters: pH between 7.2 and 7.8, total alkalinity between 80 and 120 parts per million (ppm), and calcium hardness between 200 and 400 ppm, per standards published by the Association of Pool & Spa Professionals (APSP).

Common scenarios

Pool drain and refill is indicated under conditions that routine chemical maintenance cannot resolve. The four most common scenarios in Lake Nona's pool service market are:

Decision boundaries

The choice between a full drain, a partial drain (also called a partial drain-and-dilute), and chemical-only treatment depends on measurable parameters rather than subjective assessment.

Full drain is warranted when TDS exceeds 3,000 ppm, CYA exceeds 100 ppm, or the shell requires physical inspection or repair work that cannot be performed with water present.

Partial drain (30–50% water replacement) addresses moderate TDS elevation or CYA levels in the 70–100 ppm range without exposing the full shell to hydrostatic risk. This approach is less disruptive but may require a follow-up drain within 12–18 months if underlying chemistry inputs are not adjusted.

Chemical-only intervention is appropriate when water chemistry imbalances fall within correctable ranges — typically pH drift, alkalinity fluctuation, or calcium hardness adjustments. For guidance on those maintenance boundaries, the Lake Nona pool chemical balancing reference covers applicable treatment thresholds.

Permit requirements for drain and refill vary by scope. In Orange County, routine residential drains may not trigger a formal building permit, but any associated plumbing or shell repair work may require inspection under the Florida Building Code, Chapter 4 (Plumbing). Commercial pool drainage, particularly for facilities governed by Florida Department of Health public pool standards under Florida Administrative Code Rule 64E-9, is subject to additional inspection and documentation requirements before a commercial pool may be returned to service.
