How we work
The sand filter is the second most common point of breakdown. Filter sand compacts and saturates over time, losing its filtering efficiency. The typical sign is increasing working pressure (when it exceeds 1.5 bar, it's time for a backwash or change). Sand replacement is done every 5-7 years with normal use. It's a full-day operation. It involves emptying the filter, removing the old sand (usually around 80-120 kg for a standard domestic filter), and cleaning the collector bed. Then, refilling with new sand of the correct grit size, adjusting the multiport valve, pressure testing, and commissioning.

The sign is increasing pressure that doesn't drop with backwashing and reduced filtration efficiency.
