Sewer pump installation

Most sewer pump installations run between $4,000 and $10,000. A like-for-like pump replacement on a sound existing pit with reasonable access sits at the lower end. A new pit with a high-head duty, or a dual-pump system with a control panel, sits at the upper end — and large commercial or strata systems can run beyond it. What moves you along the range is the pump duty, whether the existing pit can be reused, access to the pit, and how much electrical work is involved. We quote after seeing the site, and the quote is the job.

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.

No — though plenty of people call their sewer pit a septic pit, and we know what they mean. A septic system treats and disposes of waste on your own property, usually where there is no sewer main to connect to. A sewer pump does the opposite: it lifts waste from a property sitting below the sewer main up into Sydney Water's system, so nothing is treated or stored on site. If you are connected to the sewer and your bathroom, laundry or granny flat sits below street level, what you have is a sewer pump pit — whatever you have been calling it. So if you ring us about your septic pit and it turns out to be a pump pit, you have called the right people. If it genuinely is a septic treatment system, that is not our trade and we will tell you straight.

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.
