If your inground pool is leaking, call a repair technician immediately. Pools are designed to be watertight, but sealants break down over time and pools settle causing small cracks in the shell. Pools can also leak through fittings, accessories, plumbing, and equipment.
It is important to repair leaks to save water, heat, and chemicals, but also to prevent damage to structural components. A severe leak can wash away the fill dirt that supports the pool walls and pool deck.
