Is Your Los Angeles Pool Losing More Water Than It Should?
Every pool loses a small amount of water to evaporation — especially during hot Southern California summers. But when water loss goes beyond normal evaporation, a hidden leak could be quietly wasting thousands of gallons and damaging your deck, soil, and equipment pad. Knowing the warning signs early is the difference between a targeted repair and a costly structural overhaul.
At Finest Los Angeles Leak Detection & Repairs, we've inspected pools from Beverly Hills to Glendale, and the same warning signs appear again and again before a major leak is confirmed. Here's what to watch for.
1. You're Losing More Than 1/4 Inch of Water Per Day
A quick benchmark: Los Angeles pools typically lose about a quarter inch of water daily to evaporation during warm months. If your water level is dropping faster than that — especially overnight when evaporation slows — a leak is the likely culprit. The easiest way to check is the bucket test: fill a bucket with pool water, place it on a step at the same water level, and mark both surfaces. After 24 hours, compare the drop. If the pool lost more than the bucket, call a professional.
Our pool leak detection service uses pressure testing, dye injection, and electronic acoustic equipment to pinpoint exactly where that water is going — without guesswork or unnecessary digging.
2. Your Water Bill Has Spiked Without Explanation
A slow underground plumbing leak can be nearly invisible from the surface while adding hundreds of dollars to your water bill each month. Los Angeles water rates make even a modest leak expensive over time. If you've noticed an unexplained jump in your bill and you haven't recently changed your irrigation schedule or household usage, your pool's buried return or suction lines may be the source.
Our pool plumbing leak repair team uses pressure testing to isolate the exact line that's failing before a single shovel hits the ground.
3. Wet or Soggy Soil Around Your Pool Deck
Healthy pool decks and landscaping should stay dry between rain events. If you're noticing consistently wet soil, soft spots in your lawn, or efflorescence (white mineral deposits) on your decking, water is likely migrating underground from a pool leak. This saturation can erode the soil supporting your deck and eventually cause cracking, settling, or heaving — especially in the expansive clay soils common across Los Angeles.
Skimmer and return fitting leaks are a frequent cause of localized soil saturation near the pool wall. Learn more about our skimmer and return fitting leak repair service.
4. Visible Cracks in Your Pool Shell or Tile Line
Los Angeles pools face seismic activity and expansive soil movement that few other regions experience. Hairline cracks in plaster may look cosmetic, but a crack that extends through the shell is an active water loss point that will widen over time. Cracks near fittings, at the waterline tile, or on the floor of the shallow end are especially worth investigating immediately.
Our pool shell crack repair specialists evaluate every crack to determine whether it's a surface plaster issue or a structural through-crack in the gunite — and recommend the least invasive repair method to seal it.
5. Air Bubbles in Your Return Jets or Pump Losing Prime
If you're seeing air bubbles streaming from your return jets, or your pump is struggling to hold prime and seems to be pulling air, there's likely a suction-side leak — either in the underground suction line or at the skimmer throat. Air in the system accelerates pump wear and can eventually cause motor damage if left unaddressed.
Equipment pad leaks compound the problem. Dripping pump unions, failing filter o-rings, and deteriorated valve gaskets all contribute to air intrusion and water loss. Our pool equipment leak repair service covers the full equipment pad, not just the most visible drip.
What to Do If You Spot These Warning Signs
- Perform the bucket test to confirm water loss beyond evaporation
- Note whether loss is faster with the pump on or off — this helps narrow the leak location
- Check for wet soil, staining, or soft spots around the pool perimeter
- Look for visible cracks in the plaster, tile line, or skimmer throat
- Call a professional leak detection company before attempting DIY repairs
