Sewer pump installation

It depends on the pump type, the pit, how deep the excavation runs, and what the electrical needs — no two installs are the same, so we quote each one after a site visit rather than off a list. A straight residential replacement on a sound pit is a different job to a new install with excavation and pit work, and we'll set out exactly what yours involves before anything starts.

A standard residential sewer pump replacement is usually a single day. We carry stock for the most common pumps in Sydney, so most replacements are done in one visit and water-tested before we leave. New installs that involve pit work, excavation or new electrical take longer — we'll give you a timeframe at quote stage. For pit work specifically, see our pump pit installation page.

There's overlap in the names — most sewer pumps fit several at once. A sewer pump (or sewage pump) handles raw sewage with solids and pumps it up to the main. A sewage ejector is the same physical pump, just named for ejecting to the sewer line. A grinder pump adds a macerating mechanism that pulverises solids to a fine slurry before pumping — heavier-duty, more reliable through a modern sewer system, and our usual call. A cutter pump is the lighter-duty alternative, slicing solids rather than grinding them, fine where the waste stream is predictable. And submersible isn't a pump type at all — it just means the pump sits in the pit below the waterline, which is how almost every modern Sydney sewer pump is installed. We fit and replace all of them, and pick the right one for the property rather than a name off a brochure.

Sewer pump work in Sydney has to meet NSW plumbing standards (AS/NZS 3500). We hold NSW Plumbing Licence 456767C and the disconnection and reconnection certification, so a standard residential pump replacement is covered as part of our work — we handle the compliance side. A new connection or a more involved install can carry extra requirements, and we'll tell you what applies before we start.

Recurring alarm activation, a sewage smell around the pit, slow drainage from below-ground bathrooms, the pump running constantly without shutting off, sewage backing up into showers or toilets, bearing rumble or grinding from the pump, the pump tripping the breaker, or visible rust and corrosion on the body. If your pump is over 6 to 8 years old and showing any of these, it's worth a replacement assessment.

Yes — we work directly with builders, project managers and homeowners on new builds across Sydney. We coordinate with the construction timeline, supply and install the pit and pump system, complete the pipework and pump-side electrical, and deliver it to the relevant standards. Talk to us early, before the slab is poured.

Three main causes: the pump has failed and isn't keeping up with the inflow; the pit lid isn't gas-tight (older concrete lids commonly fail this way); or the venting is wrong or blocked. We sort all three. Our custom-spec fibreglass pits with gas-tight lids — manufactured to our own thickness specification — take the smell problem off the table for good.

We're based in the Sutherland Shire and cover all of greater Sydney. Our highest-volume areas are the Sutherland Shire, Northern Beaches, Lower North Shore, Eastern Suburbs and the Inner West. Call us with your suburb — if we don't cover it, we'll tell you straight.
