Difference between overflow in hot spring pool and overflow outside.

Operation mode and maintenance requirements.

1. Operation mode: The operation of the internal circulation system mainly depends on the circulating water pump to circulate the water in the pool and keep the water flowing. External circulation is to exchange the water in the facility with the external water source by changing water to ensure the freshness and clarity of water quality.

2. Maintenance requirements: As the internal circulating water source circulates continuously in the facility, the facility needs to be cleaned and disinfected regularly to prevent bacteria from breeding. However, due to more frequent water exchange, external circulation requires less facility maintenance.
