Pool Leak Detection Tucson:
Find and Fix Hidden Leaks
Losing water from your pool costs money every time you refill. More concerning, hidden leaks damage surrounding structures, erode soil, and waste thousands of gallons monthly. Tucson’s desert climate makes water conservation critical, yet many pool owners unknowingly lose substantial amounts through undetected leaks.
Southwest Pool Care provides professional pool leak detection Tucson homeowners trust for accurate diagnosis and permanent repairs. Our licensed technicians (ROC 332780) use specialized equipment to locate leaks without destructive digging, saving you time and property damage.

How to Tell If Your Pool Has a Leak
Normal evaporation causes water loss in Tucson’s dry climate. However, excessive loss signals actual leaks requiring professional attention. A simple bucket test helps distinguish evaporation from leaking.
Place a bucket filled with pool water on your steps. Mark the water levels inside the bucket and in the pool. After 24-48 hours, compare the difference. If pool water drops significantly more than bucket water, you likely have a leak.
Other warning signs include constantly adding water more than twice weekly, wet spots around your pool deck or equipment area, cracks in pool surfaces or tile, loose or settling pavers near the pool, and unexplained increases in water bills.
Chemical consumption also increases with leaks. Fresh water dilutes sanitizer levels, forcing you to add more chlorine and adjust chemical balances more frequently than normal. If your chemical usage suddenly spikes without explanation, investigate potential leaks.
Common Pool Leak Locations
Pool leaks develop in predictable areas based on construction methods, age, and stress points:
- Underground Plumbing – Return lines, suction lines, and drains crack from ground movement, freezing, or age. These hidden leaks waste enormous volumes of water.
- Skimmers – Leaks develop at wall penetrations where plastic meets concrete or fiberglass. Settlement cracks the bond, allowing water to seep behind pool walls. Skimmer throat cracks also permit water loss into the surrounding soil.
- Main Drains – Fittings connecting to underground plumbing develop leaks. Hydrostatic pressure from rising groundwater can crack drain assemblies from below. These leaks require pressure testing for accurate diagnosis.
- Pool Lights – Failed seals around light niches let water travel through electrical conduits to equipment areas.
- Shell Cracks – Concrete pools crack from structural movement or freeze damage. Plaster surfaces develop spider cracks, allowing water penetration. Fiberglass pools crack from poor installation or ground shifting beneath shells.

Professional Leak Detection Methods

We locate leaks using proven techniques that minimize property disruption:
- Electronic Leak Detection – We use sensitive listening equipment that amplifies sounds of water escaping under pressure. Technicians systematically scan suspected areas, identifying leak signatures. This non-invasive method locates underground plumbing leaks accurately.
- Visual Inspection – We identify obvious surface problems like cracked tiles, separated coping, or damaged fittings. Many leaks hide from visual detection, requiring technical approaches.
- Pressure Testing – We close valves, creating separate zones, then pressurize individual lines with air or water. Pressure drops indicate leaks in that specific section, pinpointing problem areas before excavation.
- Dye Testing – We inject colored dye near suspected cracks or fittings while the water remains still. Dye flowing toward leaks reveals exact entry points. This technique works particularly well for skimmer and fitting leaks.

Why Act Quickly on Pool Leaks

Delaying leak repairs compounds damage and costs. Water escaping underground erodes soil supporting pool walls and decks. This erosion causes settlement, cracking, and structural instability, requiring expensive corrections.
Wasted water impacts utility bills and strains Tucson’s limited water resources. A small leak losing one inch daily, wastes roughly 500 gallons weekly. Larger leaks waste thousands of gallons monthly at your expense.
Chemical imbalance from constant fresh water addition stresses pool surfaces and equipment. Improperly balanced water etches plaster, corrodes metal components, and requires excessive chemical purchases to maintain proper levels.

Frequently Asked Questions
Detection costs vary based on pool size and complexity. We provide upfront pricing after assessing your specific situation, allowing us to begin diagnostic work with confidence.
Most leaks are findable and repairable using modern detection methods. Occasionally, multiple small leaks or extremely old pools present challenges where total renovation proves more cost-effective than extensive repairs. We provide honest assessments of repair feasibility.
Simple leak detection completes in one to two hours. Complex situations requiring multiple testing methods or hard-to-locate leaks may need additional time. We schedule appropriately based on your pool’s characteristics and symptoms.
We minimize excavation using precise leak detection, locating exact problem areas. Small, targeted digging accesses underground leaks efficiently. We restore disturbed areas professionally after completing repairs, though some landscape restoration may be necessary.
