What is the correct position of the valves when cleaning the filters?

When cleaning the filters, the correct position of the valves is to have them open. This ensures that water can flow freely through the filtration system while you are cleaning or backwashing the filters. Open valves allow for the removal of debris and contaminants that the filter has collected, ensuring that the cleaning process is effective.

Having the valves closed during this procedure would restrict water flow, preventing proper cleaning of the filter. A half-open position might not provide sufficient water pressure or flow necessary for effective cleaning. The bypass option typically refers to a setting that allows water to circumvent the filter completely, not suitable for cleaning purposes where filtration is needed. Therefore, keeping the valves open is essential for optimal filter maintenance and ensuring the pool’s water quality remains at an acceptable level.
