A leaking swimming pool can be frustrating, especially when the issue traces back to a faulty skimmer. A pool skimmer leak is one of the most common causes of water loss, and when left unresolved, it can lead to major structural issues, wasted water, and increased chemical usage. Fortunately, pool skimmer leak repair is achievable when you understand how to detect the problem and apply the right fix.
In this complete guide, we’ll explore how to identify a skimmer leak, how to fix a leaking pool skimmer, and when to bring in professionals like Rhino Pool Pros to ensure a permanent solution.
What Is a Pool Skimmer and Why Does It Leak?
A pool skimmer sits at the waterline of your pool and removes floating debris before it reaches your filter. It plays a crucial role in keeping your pool water clean and circulating properly. However, skimmers are typically built into the pool wall or attached externally, making them vulnerable to leaks caused by:
Structural cracks in the skimmer throat or body
Improper sealing between the skimmer and pool shell
Shifting ground or settling decks
Cracks in the plumbing lines connected to the skimmer
These issues require timely pool skimmer repair to prevent more extensive damage.
Signs You Need Pool Skimmer Leak Repair
Before starting any repair, it’s important to confirm that the skimmer is the source of the leak. Here are common symptoms that point to the need for pool skimmer leak repair:
Unusual Water Loss – If you’re losing more than 1/4 inch of water per day, and evaporation has been ruled out, you likely have a leak.
Wet Soil Around Skimmer – Water escaping from a skimmer often saturates the surrounding ground.
Visible Cracks – If you can spot cracks in or around the skimmer throat or body, it’s time to act.
Air Bubbles in Pump – Air entering through a skimmer leak can cause bubbles in your return lines or noisy filtration.

How to Detect a Pool Skimmer Leak
If you suspect a leak, try these proven methods:
The Dye Test
Turn off your pool pump and let the water become still. Then, release pool dye or food coloring near the skimmer mouth. If the dye gets pulled into a crack or seam, you’ve found your leak.
Skimmer Line Plug Test
Insert a plug into the skimmer line and monitor water levels:
If the water stops dropping, the leak is in the plumbing.
If it continues, the skimmer body or connection to the pool wall is the culprit.
How to Fix a Leaking Pool Skimmer
Once the issue is diagnosed, here are the top methods to fix cracked pool skimmer components:
Apply Pool Putty or Epoxy
For hairline cracks in the skimmer body or throat:
Use underwater epoxy or pool putty.
Press it into the crack and smooth it out.
Allow time to cure according to the product instructions.
This is a quick DIY fix for minor damage.
Reseal the Skimmer Mouth
If the leak is at the skimmer’s connection to the pool shell:
Remove old silicone or sealant.
Clean the area thoroughly.
Apply a waterproof, flexible sealant around the entire perimeter.
This method addresses many common issues with vinyl and gunite pool installations.
Skimmer Replacement
For severe damage, full pool skimmer repair may require professional replacement:
Remove the old skimmer box
Cut into the surrounding deck or coping
Install and reseal the new skimmer unit
This process is best handled by professionals like Rhino Pool Pros, who specialize in custom pool renovations, deck resurfacing, and tile and coping repair.
Preventing Future Skimmer Leaks
Prevention is the best way to avoid expensive leaking swimming pool repair down the line. Here’s what you can do:
Schedule regular pool maintenance
Don’t allow your water level to drop below the skimmer line
Inspect your skimmer every season for cracks or loose fittings
Avoid heavy pool equipment placement directly above skimmer lines
If you’re closing your pool for the season, be sure to follow our winterizing guide to protect your skimmer and plumbing from freeze damage.
