How to Tell If Your Pool Has a Leak
Some water loss is normal due to evaporation, splash-out, and backwashing, but if you’re refilling your pool more often than usual, it could be a sign of a leak. Here are the most common warning signs:
1. Unusual Water Loss
On average, pools lose about ¼ to ½ inch of water per day due to evaporation.
If your pool is losing more than 2 inches per week, there’s likely a leak.
2. Increased Water Bills
A hidden leak can cause your water bill to spike unexpectedly.
If you’re using more water but haven’t increased pool use, check for a leak.
3. Cracks or Gaps in Pool Surfaces
Visible cracks in the pool walls, tiles, or decking can indicate structural leaks.
If the pool deck is sinking or shifting, it could be a sign of underground leaks.
4. Constantly Running Pool Pump
If your pump or auto-fill system is running nonstop, it may be struggling to keep up with water loss.
This increases energy costs and puts extra wear on your equipment.
5. Wet Spots Around the Pool
Soggy patches of grass or areas that stay damp may indicate an underground leak.
Water pooling under your deck or near equipment is a red flag.
How to Find a Pool Leak: The Bucket Test
Before calling a professional, try this simple DIY leak test:
Step 1: Fill a Bucket
Fill a 5-gallon bucket with pool water to about 1 inch from the top.
Step 2: Place the Bucket on a Step
Put the bucket on a pool step (partially submerged) and mark the water levels inside and outside the bucket.
Step 3: Wait 24 Hours
Leave the bucket undisturbed for a full day, keeping the pump off if possible.
Step 4: Compare Water Levels
If the pool water level drops more than the water inside the bucket, you have a leak.
If the levels drop evenly, the water loss is likely due to evaporation.
Common Types of Pool Leaks and How to Fix Them
Once you confirm a leak, it’s time to identify where it’s coming from. Here are the most common sources:
1. Structural Leaks (Cracks in the Pool)
Where to Look: Check for cracks in the plaster, tile, or concrete.
Fix: Small cracks can be sealed with epoxy or pool putty, but major structural damage may require professional resurfacing.
2. Plumbing Leaks (Pipes & Fittings)
Where to Look: If water loss increases when the pump is running, the pipes, skimmer, or return lines may be leaking.
Fix: A professional pressure test can pinpoint the exact location. Underground leaks may require excavation.
3. Equipment Leaks (Pump, Filter, or Heater)
Where to Look: Inspect around the pump, filter, heater, and valves for dripping water.
Fix: Tighten loose fittings or replace worn-out seals and gaskets.
4. Skimmer Leaks
Where to Look: Skimmer leaks often occur where the skimmer meets the concrete.
Fix: Use pool putty to seal small cracks. For severe damage, the skimmer may need replacement.
