This filter is very easy to service , with a side mount multi-port valve you won't have to undo any plumbing to access the internals of the filter .
Air is forced into the vessel to thouroughly agitate the beads and break free the entrapped debris.
The pump then gives a thourough backwash and rinse via the multi-port valve . You will enjoy the longer intervals between backwashing with these large diameter filters. A couple of the advancements have been made to the popular Challenger line of filters is the addition of the Hydraswirl technology and Sludge drains . With the Hydraswirl addition solids are spun to the center of the vessel where they wait for the operator to open the sludge drain. With this unique feature, solids are purged under pressure, while opening the Sludge drain with the pump running.
