What happens to the pressure when the filter is clogged?

When a filter becomes clogged, the pressure in the system increases. This occurs because the water flowing through the filter encounters resistance as debris and contaminants accumulate. As the ability of the filter to allow water to pass decreases, the pump must work harder to push the same volume of water through the filter, leading to an increase in pressure within the filtration system.

This rise in pressure can be critical for pool operators to monitor, as excessive pressure can indicate the need for maintenance or cleaning of the filter. If left unaddressed, high pressure can lead to more significant issues, including potential damage to the pump or filtration system. Understanding the relationship between filter condition and pressure is essential for maintaining proper pool water quality and ensuring the efficient operation of the pool’s circulation system.
