Hydrostatic Plugs

The AstralPool Hydrostatic Plug (Product Code: 16100) is a crucial safety component engineered for concrete pool shells to protect them from the devastating effects of groundwater pressure. When the water table rises beneath an empty or low-water pool, intense hydrostatic pressure builds up, which can crack the concrete or even lift the entire pool shell out of the ground. This high-impact ABS plastic plug acts as a pressure-relief mechanism, allowing excess underground water to safely enter the pool and equalize pressure, thereby safeguarding the structural integrity of your swimming pool.
