Backwash – Bottom Valves
BOTTOM MOUNT VALVES
A bottom mount valve is mounted in the base of the filter (as the name implies). Sometimes it will look like there is not a backwash valve on the filter but at closer inspection, the pool operator should find a handle sticking out of the base of the filter. This valve offers two settings, FILTER and BACKWASH.
