Underground pipes that carry water to and from your pool can develop leaks due to age, tree root intrusion, or ground movement.
Joints and fittings can loosen or degrade over time.

Skimmer
Cracks where the skimmer meets the concrete (called the "skimmer throat") are a frequent leak point.
Old or poorly sealed skimmers can also leak around the perimeter.
Return Lines
Underground pipes that return water to the pool can crack or separate over time, especially with shifting soil or ground movement.

Main Drain
Located at the deepest part of the pool. Leaks can form at the drain fitting or in the piping connected to it.
Especially vulnerable in older pools or those with settling.
Pool Shell (Surface Cracks)
Cracks in concrete, gunite, or fiberglass shells can lead to slow but steady leaks.
Look for cracks in corners, steps, and walls.
Light Niches
Behind pool lights, the niche can develop leaks, especially where the conduit connects.
Tile Line or Expansion Joint
The grout between waterline tiles and the joint between the pool wall and deck can crack and leak water.
Movement in decking or improper sealing is a common cause.
Plumbing & Equipment
Leaks can start in pump seals, filter housings, heaters, or pipe fittings.
Suction-side leaks (before the pump) may draw air; pressure-side leaks (after the pump) may lose water.
Autofill Valve
Malfunctioning autofills can hide a leak by constantly adding water, or the line to the autofill can leak underground.
