Rainwater tank plumbing and pumps in Bairnsdale
Rainwater tank plumbing near Bairnsdale: connecting a tank to the house, pumps, mains switching devices, filters, first flush diverters and backflow protection.
A rainwater tank plumber connects a tank to the house so it can feed toilets, the laundry, the garden or every tap, and fits the pump, filters, first flush diverter and, on a property that also has mains water, the switching device and backflow protection. On lifestyle and farm blocks around Bairnsdale the tank is often the only supply, so a pump or switch fault leaves the house dry. Up to three independent local plumbers receive your enquiry from this site, and each prices the tank work themselves.
How much rain does a tank around Bairnsdale collect?
Bairnsdale Airport records average about 644 mm of rain a year over roughly 141 rain days, according to the climate table on the Bairnsdale Wikipedia page. With that much rain, the size of the roof catchment and the tank both matter. A house that relies on tank water through a dry summer needs every bit of roof it can connect, clean gutters and a tank that does not leak.
Which tank setup do you have, or want?
| Setup | How it is plumbed | Typical work |
|---|---|---|
| Garden tank | Tank feeds a hose tap or irrigation only, with no link to the house | Outlet tap, small pump, overflow to the stormwater system |
| Tank to toilets and laundry with mains backup | Pump supplies selected fixtures; a switching device changes to mains when the tank is low or the power fails | Pump and switching device, separate pipework, backflow protection |
| Tank as the whole house supply | Every tap runs from the tank through a pump and filters | Pump sizing, pressure tank, sediment and other filters, low water troubleshooting |
| Extra tank linked in | A second tank connected to the first to store more | Linking pipe, levels matched, overflow route |
| Tank plus dam or bore | More than one non-drinking or drinking source on the property | Separate lines, labelling, backflow protection where sources could mix |
What does the pump need to do?
The Quote Yard’s Gippsland plumbing guide makes the point that a pump should be sized to the house, not to the tank. What counts is how many taps and appliances might run together and how far and how high the water has to be pushed. A pressure tank beside the pump stops it starting for every glass of water, which cuts wear and noise. A pump that has become louder over time can have worn bearings and be close to the end of its life.
If your pump starts with nothing turned on, water is escaping somewhere, and the tests on our leak detection page are the place to begin before replacing anything.
What is a switching device and why test it?
On a property with both tank and mains water, a switching device (sometimes called a rain to mains switch or changeover valve) lets the pump supply the house from the tank and changes over to mains when the tank runs low or the pump loses power. The Quote Yard guide calls it the part that fails quietly and says testing it twice a year takes minutes. A simple check is to turn off power to the pump and confirm water still comes from the taps it serves. If they go dry, the switch is not changing over. Ask your plumber to show you how to do this on your own setup.
Why does backflow protection matter?
Backflow is water flowing the wrong way, from a tank, dam, bore or irrigation system back into the drinking water main. Where a property has more than one supply, a fault or a pressure drop can let non-drinking water reach the mains, which affects your household and potentially the neighbours. The Quote Yard guide says backflow protection matters a great deal on farms and that homemade arrangements are where it fails. The water services part of the plumbing standards, AS/NZS 3500.1, covers backflow prevention, and a plumber should fit the device the risk calls for. Some devices are testable and need a yearly test by a plumber who holds the backflow authorisation.
If your property has mains plus a tank, dam or bore, mention every source in the enquiry, even ones you no longer use.
What does a careful tank plumber check?
- the roof and gutters feeding the tank, since the Quote Yard guide notes whatever is on the roof ends up in the tank
- leaf screens, the first flush diverter and the inlet strainer
- the tank outlet height and the suction line to the pump
- pump size against the household’s demand, and whether a pressure tank is fitted
- the switching device, if mains is also connected
- backflow protection where more than one supply exists
- filters and their cartridges, which wear out faster under a lot of trees
- where the overflow goes, so it drains away from the house and footings
They will not cross connect a tank, dam or bore to the drinking main without backflow protection, and should not leave a pump running dry. Overflow often joins the stormwater system, and our stormwater drainage page covers pits and drains if the overflow is soaking the yard.
How does the work go, step by step?
- Site check. The plumber looks at the tank, the roof catchment, the distance to the house and where the pump will sit, and asks what fixtures the tank should feed.
- Pump and power. The pump is placed on a level base, protected from the weather and close to an electrical supply. Any new power point or circuit is a job for a licensed electrician.
- Pipework. Lines are run from the tank outlet to the pump and from the pump to the house, kept separate from the mains supply where both exist.
- Controls. The switching device, pressure tank and filters are fitted.
- Protection. Backflow protection goes in where the supplies could meet.
- Testing. The system is filled, checked for leaks and run through a changeover test.
What about bushfire season?
Tanks are part of life on bush blocks around East Gippsland, and the 2019 to 20 fire season saw an evacuation centre set up in Bairnsdale, as noted on the town’s Wikipedia page. This page does not give firefighting water advice. If you want a tank or pump set up for fire use, ask the CFA or your local fire authority what they require first, then give those requirements to the plumber.
How much does rainwater tank plumbing cost?
The Quote Yard puts plumbing a rainwater tank into a house in Gippsland at $950 to $3,700, with the spread driven by the pump, the switching device and the filtration chosen. The tank itself, a concrete pad or a long trench to a distant tank are extra. Out of town, travel adds to the price, so an enquiry about tank plumbing that bundles a pump replacement with other jobs can save a second trip.
On larger blocks out towards Lindenow, a long run from the tank to the house changes both the pipe size and the pump choice. Holiday homes at places like Metung raise a different question: whether the pump and switch still work after months of sitting idle, so a test at the start of the season is a good habit.
Next step: send the tank and pump details
In your enquiry, give the tank size and what it is made of, a clear photo of the pump’s nameplate, and say whether mains water is also connected, along with any dam or bore. Describe what the tank feeds now and what you want it to feed, and what the fault is if something has stopped working. Then request a rainwater tank plumbing quote with your town and a photo of the pump and tank area.
Frequently asked questions
- Why does my tank pump keep turning on and off quickly?
Rapid on and off cycling usually points to a failed or waterlogged pressure tank, a faulty pressure switch or controller, or a small leak somewhere in the house. It wears the pump out early. Note how often it cycles with all taps off and include that in your enquiry.
- Is tank water safe to drink?
It can be, but quality depends on the roof, gutters, screens, first flush diverter, tank condition and filtration. Keep the catchment clean, empty the first flush diverter after heavy rain and replace filter cartridges on schedule. If you have health concerns, ask the Victorian Department of Health for its guidance on private drinking water.
- How do I stop mosquitoes breeding in my tank?
Every opening into the tank, including the inlet and the overflow, should be covered with fine insect mesh, and the lid should seal. Check the mesh after storms and when cleaning gutters, as it tears or comes loose over time. A plumber can fit screened fittings if the old ones are missing or damaged.
- Can I connect my tank to the house myself?
Pipework that supplies water to fixtures inside the house is plumbing work for a registered or licensed plumber in Victoria, and any new electrical circuit for the pump needs a licensed electrician. A simple hose tap on a garden tank is a different matter, but anything linked to the house supply should be done properly.
- My tank water looks cloudy or smells. What should I check?
Look for leaves or debris in the gutters and screens, and lift the lid to check for anything that has fallen in. Sediment stirred up after a dry spell can cloud the water for a while. A plumber can check and replace filters and look at the tank outlet height.
