Refill packs contain 800g (approx) of Combiphos, sufficient to re-fill the whole unit, complete with ‘O-ring’ seal. The ‘O-ring’ seal should be changed each time the Combiphos is replaced.
Refill packs ordered online are supplied in a tough plastic bag for ease of postage and delivery. Replacement ‘O-ring’ seals are supplied in the bag, including refill instructions.
The refill packs can also be registered with Cistermiser to ensure the de-scaling guarantee is maintained.
