Siliphos Combimate Refill Balls 800g With O Ring Pack High Grade Combiphos Polyphosphate

COMBIMATE REFILL BALLS 800G: Polyphosphate refill pack for Cistermiser Combimate 15mm and 22mm in-line scale reducers, and other in-line limescale reducers with a refillable dome that take loose balls. Use it in place of a Combiphos refill pack POLYPHOSPHATE SCALE INHIBITOR SPHERES: Approx. 800g of glass-like antiscalant balls, not crushed crystals or granules, so the scale reducer refill pours cleanly through the filler hole and fills the dome evenly DOME O RING SEAL INCLUDED: Every refill pack comes with one replacement O ring for the scale reducer dome, so you renew the seal at each top up and help keep the unit watertight. Fit one ring only, never two HELPS PROTECT COMBI BOILERS FROM LIMESCALE: The polyphosphate dissolves slowly into incoming mains water and helps stop scale building up where water is heated, in combi boilers, water heaters, hot pipes, showers and taps in hard water areas EASY 4-STEP REFILL: Slide the cover off, unscrew the ring and empty the old media from the dome, fit the new O ring, then refit the dome and pour the balls in through the top. Always follow your unit's instructions REFILL ONCE A YEAR, CHECK YOUR UNIT: A whole-house unit typically uses 800g in about 12 months, so top up at your boiler service. A limescale inhibitor refill, not a water softener, and not for cartridge units or salt softeners
