What to ask them
- Does the quote include through-hulls, seacocks and hose, or unit only?This is where install quotes diverge most. Get the hardware itemised or you are comparing two different jobs.
- What is the cable run, and does my existing bank and breaker suit it?An undersized run drops voltage under load, which shows up as poor output and gets blamed on the membrane.
- Where will it mount, and can I reach the prefilter and membrane from there?Servicing access decides whether the system gets maintained. Ask to see the intended location before work starts.
- Is commissioning included, and will you record a TDS baseline at handover?Without a first-day reading you have nothing to compare against when output falls in year three.
What installation involves
Intake and discharge
A dedicated raw-water intake with its own seacock and strainer, and a brine discharge above the waterline where you can see it running. Sharing an engine intake is the single most common shortcut and the one that causes air locks.
The power run
A DC system pulling 20 to 60 amps needs cable sized for the run length, its own breaker and a solid connection to the bank. On AC, whether it starts on your inverter or only on shore power and genset decides where the unit can live.
Mounting and access
The high-pressure pump wants a rigid, dry, ventilated mount. More importantly you have to reach the prefilter every few weeks and the membrane housing once a year — a beautiful install you cannot service becomes an unserviced install.
Commissioning
First run, pressure set, product water tested and a TDS baseline recorded so you can tell later whether the membrane is drifting. Ask for that number in writing at handover.

Local means local. A business is listed here when its workshop address or its own stated coverage names this area and its listing claims installation. Australia-wide suppliers are shown separately and never presented as local. This page exists because two or more providers meet both tests in Sydney and Pittwater; where only one does, the region page is the better answer and no page like this is generated.
