Filter (normal running), Backwash (reverses flow to flush the bed to waste), Rinse (re-settles the bed for 20–30 seconds after a backwash), Waste (drains the pool or vacuums heavy dirt straight to drain, bypassing the filter), Recirculate (circulates without filtering, used when dosing) and Closed. Always stop the pump before moving the handle.
MPV-T valves are top-mount, for the Waterstar T-series residential filters; MPV-S valves are side-mount. Both come in 1.5 inch and 2 inch — choose the size of your pump and pipework. All are 6-way with a pressure-gauge port; the MPV-T-15 connects to a 50 mm filter tree.
0.4–0.8 mm silica sand (FM-4-8-25) is the filtration layer used in every Waterstar filter. 0.8–1.2 mm (FM-8-12-25) is the intermediate layer specified on some commercial filters between the 1–2 mm gravel support bed and the fine sand. Never substitute building sand — it is neither washed nor graded and will channel.
Every few seasons, or sooner when backwash intervals get shorter, the water stays cloudy after a backwash, or the bed has channelled or formed mud balls. Replace the full charge with the grade on the filter's data sheet and rinse the new bed before the first filter cycle.
