Common Water Issue in BC
Pool or Spa Losing Water
A swimming pool or hot tub losing more than the normal evaporation rate may have a structural or plumbing leak. BC's pool season runs from May to September, and an undetected leak can waste thousands of litres and cause structural damage to the pool shell or surrounding deck.
Possible Causes
- •Crack in the pool shell (concrete/gunite) or liner tear (vinyl)
- •Leak at light niche conduit or skimmer fitting
- •Underground return line leak between equipment pad and pool
- •Failed pump seal or filter valve leak
- •Heater heat exchanger leak
Recommended Steps
- 1Perform a bucket test to confirm water loss exceeds evaporation
- 2Check equipment pad — pump, filter, heater, and valves for visible drips
- 3Inspect pool light niches, skimmer throats, and return fittings for cracks
- 4Schedule professional pool leak detection with dye testing and pressure testing
