Patch a small vinyl pool liner leak yourself.

Yes, you can fix it easily, and it’ll probably take less than an hour.

First, you need to find the leak. Fill a squeeze bottle with some food coloring or leak-detection dye and squirt it near the suspected area. Watch for the dye to get sucked into the hole — that’s your spot. Mark it.

Now clean the area. Scrub it with a pool liner cleaner or just rubbing alcohol. Let it dry thoroughly. Any moisture under the patch will fail.

Cut your vinyl patch round with rounded corners — sharp corners peel up. The patch should overlap the hole by at least an inch on all sides.

Apply your two-part vinyl glue (the good stuff, not general-purpose) to both the patch and the liner. Wait the time the instructions say (usually a few minutes), then press firmly and smooth out air bubbles. Weigh it down with a brick or something for a few hours.

You’re done. Future You will thank you for not calling a pool guy to do this.
