Pressure Gauge Panel

Pressure gauge panel for monitoring filter pressure. Mounts on the filter or the manifold and shows the working pressure at a glance, signalling when the sand media is loaded and a backwash is due. Note the clean-filter reading after each backwash; when the needle climbs 0.5–0.7 bar above it, backwash again. A reading that never rises points to a channelled sand bed or a leaking multiport valve, while a reading that stays high after backwashing points to calcified sand that needs replacing. Fits the standard gauge port on Waterstar top-mount and side-mount filters.
