Customer Concern
The homeowner reported ongoing water loss and suspected a leak in the pool plumbing. Water loss increased when the circulation system was running, raising concerns about a possible underground or return-line issue.
Pool Details
Pool type: Concrete
Approximate age: Not specified
Location: Jupiter Farms, Florida
Notable features: Bench seating area with dedicated return line
Diagnostic Process
A complete swimming pool leak detection was performed using multiple diagnostic methods to isolate the source of the water loss.
Visual inspection of the pool shell, fittings, and equipment
Dye testing of suspected structural and fitting areas
Pressure testing of individual plumbing lines
General system evaluation under operating conditions
Due to steady rain during the appointment, hydrophone testing was limited. However, dye testing provided strong indicators early in the inspection.
Findings
Dye testing revealed consistent pull at the return fitting located in the bench seating area. Subsequent pressure testing confirmed that the return line serving the bench would not hold pressure, indicating a break in the plumbing line.
All other plumbing lines were appropriately tested, isolating the issue to the single bench return line.
Recommended Solutions
Two practical options were presented to the homeowner:
Option 1: Permanently turn off the compromised bench return line by keeping the valve closed and installing rubber expansion plugs in the return fitting. This removes the failed line from operation while maintaining circulation through the remaining returns.
Option 2: Perform a complete plumbing repair by cutting into the concrete deck, locating and repairing the damaged line, and repouring the deck to restore full functionality.
Each option was explained, along with its pros, cons, and level of invasiveness.
Customer Decision
The homeowner elected to proceed with Option 1, eliminating the bench return line. Because the pool had multiple other functioning return jets, circulation remained adequate without the need for deck demolition.
Outcome
The failed return line was successfully removed from operation, eliminating the source of the leak. The homeowner was provided with clear documentation of the findings and recommendations for future reference should a permanent repair be considered later.
