Why are fiberglass pools built without a weir?

Fiberglass pools are typically built without a weir because they rely on a different design for water circulation and filtration. Instead of using a weir, these pools often incorporate a skimmer system that effectively removes debris from the water's surface. This design minimizes the risk of leaks and structural issues associated with weirs, while also simplifying maintenance. Additionally, the smooth, non-porous surface of fiberglass helps reduce the accumulation of dirt and algae, enhancing overall pool hygiene.
