Frequently asked questions
Which filter diameter matches my pump?
Each top-mount filter is rated at 50 m³/h per m² of bed area: Ø500 mm = 10 m³/h, Ø600 = 14, Ø750 = 19, Ø900 = 32 and Ø1005 = 43.5 m³/h. Choose the filter whose rated flow is equal to or higher than the pump's design flow — a filter that is too small for the pump lets dirt through and shortens cycles. Match the multiport valve size (1.5 or 2 inch) to your pipework.
What sand does the filter take and how much?
Graded silica sand 0.4–0.8 mm (product FM-4-8-25, 25 kg bags). The Ø1005 mm filter also takes a 1–2 mm gravel underbed. The number of bags depends on the diameter and bed depth — it is on each filter's data sheet, or ask our team with the model number.
When should I backwash?
Note the pressure gauge reading with a clean bed after each backwash. When the reading rises about 0.5–0.7 bar (7–10 psi) above that, or at least weekly in season, backwash until the sight glass runs clear, then rinse for 20–30 seconds before returning to Filter. Always stop the pump before moving the valve handle.
Top-mount or side-mount?
Top-mount filters (this range, Ø500–Ø1005 mm) carry the multiport valve on the vessel and are the compact choice for villa and residential pools. Side-mount filters (Waterstar WS series, Ø1200–Ø2000 mm) have the valve on a separate manifold and a manhole for media changes, and are built for hotel, club and public pools.
