WasteWater Accessories

Compatibility comes down to the manufacturer and model of your plant — a BioDisc part won't fit a BioTec or Klargester BioFicient system, for example. Check the data plate on your tank for the model reference before ordering, and if you're unsure, get in touch with details of your make and model so we can confirm the correct fit.

Air pumps and blowers on sewage treatment plants typically run continuously, so diaphragms and internal components wear over a few years of constant use. Most manufacturers recommend checking annually and budgeting for replacement every 2-4 years depending on usage and site conditions. A failing blower is often the cause of poor treatment performance or odour complaints, so it's worth investigating first if your system isn't performing.

Yes — oil and forecourt separators require regular inspection and servicing to remain compliant with British Standard EN 858 and your discharge consent conditions. Alarms, coalescing filters and shut-off valves are all wear items that need periodic checking or replacement to ensure the separator keeps working effectively. Neglecting these accessories is a common reason separators fail environmental inspections.

A pre-filter or in-tank filter basket stops leaves and coarse debris entering the tank before storage, while a calmed inlet reduces disturbance of settled sediment at the base. Many systems also benefit from a floating suction filter, which draws water from just below the surface where it's cleanest. These accessories work together to keep water quality suitable for non-potable uses such as toilet flushing or garden irrigation.

Straightforward items like filters, alarms and float switches are generally fine for a competent homeowner or groundworker to fit. However, anything involving electrical connections — blowers, control panels, level sensors — should be installed or checked by a qualified electrician, and work on sewage treatment plants should follow the manufacturer's instructions to avoid invalidating any warranty.

Start by checking the blower or air pump is running and the diffuser isn't blocked, as loss of aeration is one of the most common causes of alarms. Also inspect the float switch for debris or fouling, as a stuck float will give false readings. If the alarm persists after checking these, it's worth arranging a service visit, as it could indicate a desludge is overdue or a mechanical fault within the plant.
