Cartridge filters
Hose cartridges clean when pressure climbs above its normal running range, and replace them when the pleats no longer come clean or start to collapse. A tired cartridge quietly lets fine debris straight back into the pool.
Media filters
Sand and glass media do not last forever. When backwashing no longer restores performance, a media change usually brings filtration back to where it should be.
Chlorinator cells
Scale on the plates reduces output, so the pool reads low on chlorine even though the chlorinator looks like it is working. Cells need periodic cleaning and eventually replacement.
Before you replace anything
Plenty of faults come down to a fuse, capacitor, seal or cell rather than the whole unit. We diagnose first and explain the options — if replacement genuinely is the better value, we will tell you why.
