Your pool should be the easiest part of your home to enjoy, rather than a mystery you’re troubleshooting every weekend. If you’ve noticed your water level dropping faster than usual, or your water bill creeping up for no clear reason, you might be dealing with a leak. Arlington-area pools stay in near-constant use through our long, hot swim season, so a small leak can turn into a big repair bill if it goes unnoticed.
Pool leaks almost always leave clues, so you just need to know what to look for. Aquamaid walks you through common pool leak signs so you’ll know when to call us for pool repair.
Signs Your Swimming Pool Is Losing Water
Every pool loses a little water to evaporation, and even more so during a Texas summer when temperatures push past 100 degrees. This makes it tricky to tell the difference between “normal” water loss and an actual leak. Many homeowners write off early warning signs as just the heat doing its thing, and the leak keeps growing.
If you notice any of these pool leak signs, your problem is likely more than normal evaporation:
1. You’re Adding Water More Than Once a Week
Evaporation typically accounts for about a quarter-inch to half-inch of water loss per day in hot weather. If you’re topping off your pool significantly more than that multiple times in the same week, it’s one of the clearest pool leak signs there is.
If you want to see how much water loss you’re having, try the bucket test.
- Fill a bucket with pool water
- Mark the water line inside the bucket
- Place the bucket on a step in your pool
- Mark the pool water level on the outside of the bucket
After 24 hours, compare the two. If the pool’s water line dropped more than the bucket’s, you likely have a leak rather than simple evaporation.
2. Your Water Bill Has Unexpectedly Spiked
If your pool has an auto-fill system, a leak can hide in plain sight; your pool goes on quietly refilling itself while your water bill climbs. Many Arlington homeowners don’t catch a leak until they open a bill that’s noticeably higher than previous months with no other explanation, like a new appliance or extra guests.
3. Cracks, Wet Spots, or Soggy Ground Near the Pool
Walk around the pool and look for:
- Cracks in the concrete deck
- Unusually soft, soggy, or sinking soil near the pool equipment or shell
- Standing water where there shouldn’t be any
- Discoloration or staining on the pool structure
These are strong visual indicators that water is escaping somewhere it shouldn’t. Leaks are most common near plumbing lines, skimmers, or the pool’s structural joints.
4. Algae or Cloudy Water That Won’t Clear Up
If you’re balancing chemicals correctly but your water keeps turning cloudy or growing algae, a leak could be the culprit. Leaks can throw off your chemical balance by constantly diluting treated water with untreated fill water, making it feel like you’re fighting a losing battle no matter how much you increase chemical usage.
5. Water Pooling Near the Filter or Equipment Pad
If you notice damp ground, dripping, or standing water around your filtration system, the leak is likely happening at the equipment pad. Cracked filter housings, worn O-rings, or a valve that isn’t sealing properly can all cause slow leaks that show up as puddling near the filter rather than a dropping water level.
Left alone, these issues tend to get worse, and what starts as a simple pool filter repair can turn into a bigger, costlier fix if the leak damages surrounding equipment or plumbing connections.
6. Your Pump Runs but the Pressure Feels Off
A drop in pump pressure, unusual air bubbles coming from your return jets, or a pump that seems to be working harder than usual can all point to a leak in the plumbing system rather than one limited to the pool’s plaster or shell. This is one of the trickier pool leak signs to diagnose yourself, since it often involves underground lines rather than a straightforward pool pump repair.
7. Cracked or Loose Tiles, or a Shifting Pool Structure
If tiles are loosening, the coping or the pool’s plaster is cracking, or you notice widening cracks and the pool deck shifting slightly, water may be seeping beneath the structure and eroding the supporting soil. This is one of the more serious signs your pool has a leak, since it can affect the pool’s structural integrity over time.
A Leak Can Cause Far Worse Damage If Not Corrected
Arlington’s clay-heavy soil expands and contracts significantly with moisture changes. A leaking pool that goes unaddressed can saturate the ground beneath it. As water escapes into the soil, it can cause shifting, cracking, and far more expensive structural repairs down the road.
What starts as a small, fixable leak can turn into a full deck or shell repair if it’s left to run through an entire swim season.
