ClearwaterAccessories / Spares

Air blowers are matched to specific Clearwater models and their airflow requirements, so it's important to check your unit's model and serial number before ordering a replacement. Fitting the wrong blower can starve the system of oxygen, slowing down the biological treatment process. If you're unsure, the data plate on your tank or your original installation paperwork will confirm the exact model.

Most Clearwater filters benefit from a rinse or inspection every few months, with full replacement typically needed on an annual basis, though this varies with household usage and how well the system is maintained. A clogged filter restricts flow and can cause the system to back up or reduce treatment efficiency. Keeping a spare on hand means you're not left waiting when one needs swapping out.

Alarms are usually triggered by a high water level or a fault with the pump or blower, and they're designed to give you early warning before a small issue becomes a system failure. Check the control panel for any fault codes and inspect the blower and pump for obvious signs of malfunction. If the alarm continues after a basic check, it's worth arranging a service visit rather than ignoring it, as sewage systems can escalate to overflow quickly.

Standard Clearwater lids are designed for pedestrian access only and are not rated for vehicle loading. If your tank sits under or near a driveway, you'll need a load-rated cover or riser system rated for the expected traffic, fitted in line with the manufacturer's guidance. Always check ground conditions and depth before assuming a lid upgrade alone will suffice.

Simple parts like filters and lids can generally be replaced by a competent homeowner following the manufacturer's instructions. Electrical components such as blowers, pumps and alarm units should be fitted or replaced by a qualified engineer, both for safety and to avoid invalidating any warranty on your system. If you're at all unsure, it's worth getting a service technician to carry out the swap.

We keep common Clearwater spares such as filters, blowers, alarms and lids in stock for quick despatch, as we understand a faulty part can mean your treatment system isn't working properly. Less common or model-specific parts may take a little longer, so it's worth having your tank's model details ready when you enquire. If your system is showing signs of failure, isolating the power to the blower or pump can help prevent further issues while you wait for the replacement part.
