A pool losing water is not automatically a liner problem. Gaskets, the skimmer throat, the light niche and the plumbing all leak, and a failed gasket is a $100 to $400 fix. This page shows the order to check things in, before anyone quotes you a liner.
Measure the drop over 24 hours with the pump off, and again with the pump running. A leak that only shows when the pump runs points at pressure-side plumbing; a steady drop with the pump off points at the shell, the liner or a fitting. Evaporation in a North Carolina summer is real, so compare against a bucket left beside the pool for the same period.
These are the fittings that fail first, and they fail again a season later if they are not replaced while the water is out.
Liner leaks show as small punctures, splits at a corner or a step, or generalised seepage through brittle vinyl. A single puncture is a $150 to $600 spot repair. Multiple leaks, or a liner that cracks when it flexes, means replacement rather than patching.
The cost of waiting is what matters: water leaking behind the liner keeps the wall wet, accelerates corrosion and washes out the floor base. That is how a gasket job becomes a $1,200 to $3,000 floor rebuild.
Wake County soil is clay-heavy and drains slowly. Water that escapes from the pool stays near the shell instead of draining away, and the ground stays saturated against the wall. On top of that, seasonal movement of expansive clay can open small cracks and separate fittings. The practical rule: fix drainage as well as the leak, or the same spot fails again.
Run the pump-off test, then the pump-on test, and compare with a bucket of water left beside the pool. If the loss only happens with the pump running, suspect plumbing. If it is constant, suspect the shell, liner or fittings.
A single puncture or tear, yes, for $150 to $600, and gasket work for $100 to $400. A brittle liner with several leaks is not a repair candidate.
Yes. Water sitting against a steel wall accelerates corrosion and can wash out the floor base under the liner, turning a small repair into a structural job.
