Filter Cartridge Replacement

What filter cartridge replacement covers

A straightforward, professional cartridge change, carried out to protect your filtration unit and your plumbing.

• Confirming the filtration unit type and cartridge specification
• Isolating the water supply and safely depressurising the housing
• Removing the used cartridge and checking the housing, threads and seals
• Fitting the new cartridge and lubricating or replacing seals where needed
• Flushing the system to clear trapped air and fine carbon or sediment
• Leak checks and flow checks at the unit and relevant taps
• Advice on replacement intervals based on usage and local water conditions

When this service is most useful

• Water flow has dropped, or the filter seems to block quickly
• Water has started to taste or smell different
• You have a limescale or sediment pre filter that is due its routine change
• You are managing a rental property and want planned, documented maintenance
• A filtration unit has been installed recently and needs its first change

How the cartridge is replaced

The system is isolated, pressure is released, and the filter housing is opened carefully to avoid damaging threads or seals. The used cartridge is removed, the housing is cleaned as appropriate, and a new cartridge is fitted correctly and tightened to the right level. The system is then flushed and checked for leaks and proper flow before being left in service.

Aftercare and ongoing value

You will be advised when the next change is likely due and what early warning signs to watch for. If your system uses more than one stage, you can also plan a schedule so cartridges are changed in the right order. Regular replacements help maintain consistent performance and reduce the risk of filter related leaks or restrictions.
