Patch it, don’t replace it.

Yes, you can fix a vinyl liner leak without ripping the whole thing out. Usually takes an afternoon and about $20.

First, find the leak. Wait for a calm day and look for bubbles, or use a pool leak dye kit – just squirt the dye near seams and fittings and watch where it gets sucked in. Mark the spot with a weighted object or a piece of tape on the deck.

You don’t need to drain the whole pool. Drop the water level a few inches below the leak. Clean the area with a vinyl cleaner or rubbing alcohol – oils and algae will kill the bond. Cut a patch that overlaps the hole by at least an inch on all sides, round the corners (so it doesn’t peel up), and apply underwater vinyl patch glue or a pre-glued patch. Press hard and hold it for a minute.

If the leak is at a seam or around a light housing, you might need a specialized repair kit from a pool store, but it’s still a patch job, not a liner replacement.

Don’t drain the pool completely unless you know what you’re doing – vinyl liners shrink and shift when empty, and reinstalling one is a nightmare
