Nothing can be better than owning a swimming pool, but have you started to notice that your pool water seems to be draining faster than normal or accumulating around? There is every possibility that it is leaking since leakage can seriously damage the pool and cause increased costs over time. Common causes include aged materials, ground motion, severe weather, and poor installation. In this guide, we’ll explore how to find a pool leak, locate its source using simple tests or professional methods, and apply the right fix.

Recognizing the Signs of a Pool Leak
Leaks in pools can start subtly but lead to major issues.
Unusual Water Level Drops vs. Normal Evaporation
Evaporation occurs in every pool. These depend on temperature, humidity, wind, and how often the pool is used. So up to about ¼ inch per day is about average for evaporation loss in a backyard pool. If the level drops more than that, it usually indicates a leak may be developing. Observe the water loss when the pool is not in use, and the pump is switched off to confirm. Significant drops without external factors like weather changes are a red flag.
Spotting Pool Leak Through Cracks and Drips
Leaks often manifest as visible cracks in the pool’s walls or decking. Inspect the surrounding areas for wet spots, indicating water escaping from the pool. Additionally, check equipment like pumps, filters, and heaters for any signs of dripping or moisture around fittings.
Monitoring Water Bills and Chemical Usage
A sudden spike in your water bill is another potential pool leak detection factor. Similarly, if you add chemicals more frequently to maintain water balance, a leak could be the culprit. This happens because the escaping water removes pool chemicals, throwing off the balance.
Basic Tests to Confirm a Pool Leak
Before diving into repairs, confirming there’s an actual leak is essential. Here are some simple yet effective methods:
Bucket Test: The bucket test helps differentiate between normal evaporation and a leak.
- Fill a bucket with pool water about 2 inches from the rim. Place the bucket on the pool step, keeping the water levels inside and outside equal.
- Mark both levels and let it sit for 24 hours.
- Compare the water levels. If the pool’s level drops more than the bucket’s, you likely have a leak.
Dye Test: A dye test pinpoints the leak’s location:
- Turn off the pool pump.
- Use food coloring or a pool dye kit.
- Squirt dye near suspected leak areas, such as cracks, skimmers, or returns. Watch for the dye being drawn into the leak.
Inspecting Pool Equipment: Pumps, filters, heaters, and pipes are some pieces of equipment that are prone to leaking. Look for drips, rusty spots, or loose fittings.
How to Find a Leak in an Above-Ground Pool
Above-ground pools often develop leaks in liners, frames, or connections, but a systematic approach can help locate the issue.
Inspecting Vinyl Liner Seams and Walls
Vinyl liners wear out most around the seams. If you wonder how to find a pool leak, check to see if there are any discolored areas, spots that feel softer, or spots that are damp to the touch.
Checking the Pool Frame and Connections
Above-ground pool frames can develop rust or loosened hardware, causing leaks. Inspect the frame and connection points, tightening or replacing parts as necessary.
Detecting Pool Leaks from Pinholes and Rusted Panels
Small pinholes can cause significant water loss over time. Run your hand or a soft cloth along the liner to detect tiny holes. If you suspect a hole, use a patch kit to repair it.
How to Find a Leak in an In-Ground Pool
In-ground pools are more complex than above-ground pools, requiring detailed inspections of the shell, fittings, and plumbing to find pool leaks effectively.
Examining Concrete or Fiberglass Shells
Cracks in concrete or fiberglass pools often result from ground movement or natural wear over time. Examine the shell for visible splits or hairline cracks. Even minor cracks can allow water to escape.
Investigating Skimmers, Returns, and Plumbing
Fittings like skimmers and return jets often loosen due to constant water flow and pressure. Check these areas carefully for leaks. Plumbing systems can also develop cracks or loose connections that require attention.
Professional Leak Detection Methods
Professional leak-detecting services should be contacted if none of the DIY techniques work. Use specialized leak detection instruments by the most elite professionals, such as pressure testing, ultrasonic equipment, or underwater cameras, to locate these leak problems.
Fixing Common Pool Leaks
Once you’ve identified the source of the leak, it’s time to fix it. Here are solutions for common leaks:
- Repairing Vinyl Liners: You can use a patch kit for small rips or even pinholes in a vinyl liner. Some patches can even be placed underwater, making the process quick and straightforward. For extensive damage, consider replacing the liner.
- Sealing Cracks in Concrete or Fiberglass: Epoxy or pool putty is effective for sealing minor hairline cracks in concrete or fiberglass. However, larger cracks usually require professional repairs to ensure a longer life.
- Addressing Equipment and Plumbing Issues: The most effective way to prevent your machines from leaking is to change the damaged seals, o-rings, or broken sections of pipe. Hiring a plumber is the right choice in such a scenario when the whole plumbing is in a mess.
Deciding Between DIY vs. Professional Repair
While many leaks can be fixed with DIY methods, some require expert attention. Minor issues like small tears or loose fittings are manageable with basic tools and pool leak repair kits. For some complicated structural damage problems, like the big plumbing leak, professional intervention is needed to prevent further damage to the plumbing and/or structural damage.
Preventing Future Leaks and Maintenance Tips
For pool maintenance, it is better to prevent than cure. So, check your pool regularly for cracks, drips, or unusual water loss. Look for these minor details before they escalate. Also, keep the water chemistry at equilibrium with properly balanced pH and alkalinity levels to prevent wear and tear on your pools and equipment. During colder months, winterize your pool by draining lines and using a cover to prevent freeze damage. Besides, clean and service your pool equipment routinely to make it work better and meet the best conditions possible for less likelihood of future leaks.
