Davey pumps — installation, repairs & service, Sydney
Davey submersibles are some of the most common pumps in Sydney's sewer and stormwater pits — and a brand we install, repair and service every week. New systems sized properly, like-for-like replacements, and floats and valves on the van for the quick fixes.

The Davey pumps in Sydney's pits
Davey is an Australian pump maker, and it shows in Sydney's pump pits — Davey submersible sump, drainage and sewage pumps are everywhere, from single-pump pits behind homes to dual-pump packages under strata buildings. Being locally supported also means parts stay available, which keeps repairs viable on units that would be a forced replacement with lesser-known brands.
We've worked on Davey pumps for as long as we've specialised in this trade. The faults follow the same pattern as any hard-working submersible: floats foul, seals wear, and the occasional wet wipe brings the whole show to a stop. When it's a float or a jam, we fix it on the spot; when it's more than that, replacement is usually the smarter money — and we'll tell you which it is before anything comes apart.
Every Davey visit gets the same treatment as the rest of our repair work: a megger test on the motor windings, an amp-draw reading at the panel, the float run through a full cycle, and an honest call on whether the pump is worth repairing — quoted on the day, before we start.
New Davey installations & replacements
Installation is the heart of what we do — and Davey is one of the brands we fit most. New single and dual pump systems on new pits, like-for-like replacements onto existing pits and pipework, and upgrades where the old system was never sized right to begin with.
Every install is sized to the actual head and flow the system has to move — not just whatever's on the shelf. Pump, floats, non-return valves, control panel and alarm set up and commissioned as one job, with the pump-side electrical done in-house under our Restricted Electrical (Motors) endorsement.
See our sewer pump installation and stormwater pump installation pages for what a full installation involves — including our custom fibreglass pits.
What goes wrong with Davey pumps
The same handful of faults takes down most Davey systems we attend — and most of them are fixed in a single visit.
🎈
Float switch failure
The most common fault on any submersible, Davey included. Floats foul on fat and wipes in sewer pits, hang up on cabling, or the switch itself wears out. We carry compatible floats on the van and set the levels properly on the way out.
🧻
Jammed impeller
Wipes, rag and stringy material stop a vortex pump the same way on every brand. We lift the pump, clear the jam, inspect the impeller for wear and damage, and recommission with a full cycle test.
💧
Seal wear and moisture ingress
Worn shaft seals let water track into the motor. It shows up as falling insulation resistance on a megger test long before the pump dies — which is why we test every visit, and why a serviced Davey outlasts a neglected one by years.
⚡
Motor at end of life
A pump that hums but won't spin up usually has a motor on the way out. We megger-test it on the spot — and when the windings are done, the honest answer is a new pump fitted to the same pit, not money spent patching an old motor.
🚪
Non-return valve trouble
Not a fault of the pump itself, but it takes Davey systems down all the same — a jammed valve lets pumped water fall straight back into the pit. We replace valves and check the discharge side on every repair.
⏱️
Short cycling and control faults
Floats set at the wrong levels, undersized pits, or control panel faults make any pump start and stop far more than it should — and that's what wears motors out. We reset the system so it cycles the way it was designed to.

- Megger and amp-draw testing on every visit — repair decisions made on numbers, not guesses
- Pump-side electrical handled in-house under our Restricted Electrical (Motors) endorsement
- Like-for-like replacement on the existing pit and pipework when a repair isn't worth it

The credentials behind the repair
Pump repair touches licensed plumbing, restricted electrical and confined-space entry — here's what backs every Davey job we sign off.

Specialist focus since 1985
A plumbing trade since 1985, pumps-only since 2010. You deal with the same operators from first call through to commissioning.
Davey pump FAQs
Straight answers about Davey pump repairs and servicing in Sydney.
Do you install new Davey pumps?
Yes — installation is the heart of what we do. We supply and install new Davey sewer, stormwater, sump and drainage systems, single and dual, on new pits or onto your existing pit and pipework. Every system is sized to the actual head and flow it has to move, then commissioned with floats, valves, control panel and alarm as one job. See our sewer pump installation page for the full process.
Do you repair Davey sewer and stormwater pumps?
Yes — Davey is one of the brands we see most across Sydney. We repair and service Davey submersible sewer, sump, drainage and stormwater pumps, single and dual installations, including the float switches, non-return valves and control panels around them.
Do you carry Davey parts on the van?
We carry the parts for the repairs genuinely worth doing — float switches and common non-return valves compatible with Davey systems. Beyond a float or a blockage, replacement is usually the smarter money, and full replacement units are a same-day or next-day pickup from our supply partners, fitted straight onto your existing pit.
My Davey pump hums but won't start. What is it?
Usually a jammed impeller or a motor at the end of its life. We run a megger and amp test before touching anything — if it's jammed we clear it on the spot, and if the motor's done we'll say so straight: on most units a new pump beats patching an old motor on both cost and lifespan.
Is it worth repairing an older Davey pump?
If it's a fouled float or something jamming the pump — yes, that's a quick fix and worth doing. Beyond that, honestly, usually not: once the motor or seals on an older unit are gone, a new pump wins on cost and lifespan, and Davey's local availability makes like-for-like replacement easy on the existing pit. We run the megger test first and give you the straight call. See our pump repairs page for the framework we use.
Can you replace my Davey with the same model?
In most cases we can fit a current Davey equivalent — or another brand if it suits the duty better — straight onto your existing pit and pipework. We size the replacement to the actual head and flow your system needs rather than just matching the label. Our sewer pump installation page covers what replacement involves.
Do you service Davey pumps, not just repair them?
Yes — annual servicing for sewer pumps and biannual for stormwater is where most owners save money, because float fouling, seal wear and falling insulation resistance all show up on a service before they become a failed pump. See our pump servicing & maintenance page.
Prefer we call you back?
Send your name, number and what's going on — we'll get back to you the same business day. For active flooding or sewage backup, please call instead.
Urgent? Call 0415 210 267 — 24/7.
