So, you’ve spotted a leak in your pool—but the thought of draining thousands of gallons of water sounds like a total nightmare, right? Don’t worry. You can absolutely patch your pool underwater, and we’re going to show you how to do it safely, step by step.
Why Patching Underwater Pools Matters
Leaks in pools can sneak up on you and cost a fortune if left alone. Constantly adding water isn’t just a money-sucker—it can damage your pool structure, increase chemical costs, and waste resources.
Patching underwater saves water, time, and a lot of stress. With the right materials and steps, it’s totally doable and totally worth it.
Is It Safe to Patch Underwater Without Draining?
Yes—if you follow proper precautions. Underwater patching is common in both home pools and professional settings. The key? Safety, planning, and the right tools.

Tools and Materials You’ll Need
Essential Pool Repair Tools
Before diving in (literally), gather your gear. Here’s what you’ll want on hand:
- Waterproof vinyl or epoxy patches
- Underwater adhesive
- Pool putty (for concrete pools)
- Scissors or utility knife
- Goggles and swim gear
- A weight belt (optional but helpful)
These tools help you stick to safe patching techniques and avoid sloppy repairs.
Choosing the Right Patch Material
Whether you go with a vinyl patch or epoxy, the right material depends on your pool type:
- Vinyl patches = best for vinyl-lined pools.
- Epoxy = best for plaster, fiberglass, or concrete pools.

Step-by-Step Safety Process
Let’s jump right into the 9 steps that make underwater patching safe and effective.
Step 1: Inspect the Damage First
Before you suit up with patches and glue, take a close look at the problem area.
Tips for Accurate Underwater Inspection
- Use goggles or a diving mask.
- Scan for bubbles—leaks often create small streams.
- Use underwater cameras or mirrors if needed.
Our inspection and diagnosis guide covers advanced techniques for tricky spots.
Step 2: Confirm the Leak Source
Leaks are sneaky. You might patch the wrong spot if you’re not careful.
Use a Dye Test for Leak Detection
Grab some pool-safe dye, squeeze it near the suspected leak, and watch where it flows. It’s one of the easiest leak detection tricks in the book.
Step 3: Turn Off Pool Equipment
Power down everything—pumps, filters, skimmers. This prevents water flow from interfering with your repair. It’s a small step with big safety implications.
Step 4: Wear Proper Safety Gear
Don’t wing it in swim trunks. Gear up to stay safe and effective.
Underwater Visibility and Protection
- Goggles/mask to see clearly
- Gloves for hand protection
- Weight belt for steady balance if you’re deep underwater
Even basic routine checks benefit from proper gear.
Step 5: Clean the Affected Area Thoroughly
Use a pool brush or sponge to scrub off algae, dirt, or debris. A dirty surface = a failed patch. Clean it well or risk doing it all over again.
Step 6: Cut Patch Material Precisely
Trim your patch to cover the damage with at least an inch of overlap on all sides. Round the corners! Sharp ones can peel off easily.
Step 7: Apply the Patch Correctly
Now it’s time to seal the deal—literally.
Using Epoxy vs. Vinyl Patch
- Epoxy: Mix as instructed, smear on, and press firmly.
- Vinyl patch: Apply underwater adhesive, then press on.
Use money-saving patch tips to make every inch count.
Step 8: Hold the Patch in Place Firmly
Don’t just slap it on and swim away.
How Long Should You Hold It?
Hold it for at least 30-60 seconds. Some adhesives need a bit longer—check the label.

Step 9: Monitor and Reinspect the Patch
After 24-48 hours, check if the patch is holding. Use dye tests again if you’re unsure.
For long-term results, consider a maintenance plan to prevent future damage.
