Parts& Accessories

Blowers and motor/gearbox kits are usually model-specific, so you'll need the make and model of your treatment plant (often on a data plate near the lid or control panel) before ordering. If you're unsure, check the part number stamped on the existing unit, as manufacturers frequently update spares across several plant generations. Fitting the wrong kit can affect aeration rates and treatment performance, so match by model rather than by tank size alone.

Straightforward items like filters, air diaphragms, and ventilation covers are generally fine for a competent DIYer to fit. However, anything involving electrics — blowers, pumps, control panels — should be installed or at least isolated by a qualified electrician, and some sewage treatment plant work may need a registered installer to keep warranties and building control sign-off valid. If in doubt, check your original installation certificate before starting work.

Only use cleaning and descaling products specifically formulated for septic and sewage treatment systems, as ordinary household bleach and strong chemical cleaners can kill the beneficial bacteria that break down waste. Biological accelerants and sludge treatments help maintain digestion efficiency, especially after periods of low use. Always follow dosing instructions closely, as overuse can upset the biological balance just as much as underuse.

Yes — leak detection is particularly worthwhile for underground or bunded tanks where a slow leak might go unnoticed until water loss or contamination becomes significant. Detectors range from simple float-based alarms to more sophisticated sensors that alert you via a control panel or remote signal. This is especially useful for fuel and cylinder tanks, where early detection can prevent costly environmental or safety issues.

Diaphragms and filters on blowers typically need checking annually and replacing every one to two years, though this varies by usage and manufacturer guidance. A blower running noisier than usual, or reduced aeration in the tank, is usually a sign parts need attention sooner rather than later. Keeping spares on hand avoids extended downtime, since an inactive blower can quickly lead to odour and treatment problems.

Yes, solar kits are commonly used to power blowers, pumps or alarm systems on remote sewage treatment plants and rainwater harvesting systems where mains electricity isn't readily available. You'll need to size the panel and battery to match the running current of the equipment being powered, particularly for continuous-duty blowers. It's worth checking expected daylight hours for your site, as undersized systems in shaded or low-light locations won't keep up with demand.
