Rainwater tanks & pumps

Tank installs · Changeovers · Pressure pumps · Tank-to-house plumbing · Filtration

For the blocks where the tank is not optional.

On acreage through Dural, Kenthurst, Annangrove and Glenorie, and on the bush blocks off the beaten track, the tank is the water supply rather than a garden accessory. When the pump goes, the house has no water, and that is a different level of urgent.

The short answer

Rainwater tank plumbing covers connecting a tank to roof catchment, plumbing it into the house, installing and repairing pressure pumps, and water filtration. On properties connected to town water, a tank usually supplies garden taps, toilets and laundry. On unsewered acreage without a town water connection, the tank is the entire household supply, so a failed pump means no water at the taps at all. Common faults are a pump that will not start or cycles constantly, low pressure, air in the lines, a blocked or unmaintained first-flush and leaf diverter, and sediment carried through into the house.

Common tank and pump problems

Most tank callouts are the pump, the plumbing between the tank and the house, or maintenance that has been skipped.

If you are on tank water and you have no water at all, treat that as urgent and call. A household cannot function without water and it is usually a same-visit fix once we are there.

How it works

How we approach tank and pump work

1

Find out what you are running

How the property gets its water, whether there is a town connection at all, tank type and size, pump make and age, and what the house actually needs. Tank setups are individual and most have been added to over time.

2

Diagnose the pump properly

Power, pressure switch, cut-in and cut-out pressures, the pressure vessel, air locks, non-return valves and the suction side. Pumps get replaced unnecessarily quite often when the fault is a switch, a valve or a leak.

3

Check the whole path the water takes

Roof catchment, gutters, leaf diverters, first-flush arrangement, inlet screens, tank outlet, filters, pump, then the run to the house. A pressure problem is frequently a blockage upstream of the pump.

4

Repair or replace, with the reasoning

If a pump is repairable and worth repairing, we repair it. If it is old, undersized for the house, or has failed a second time, we will tell you that and what a suitable replacement looks like.

5

Sort out filtration if it is needed

What filtration makes sense depends on what the water is doing and what it is used for. A garden supply and a whole-house drinking supply are different requirements and should not be treated the same.

6

Talk about maintenance before we leave

Screens, diverters, filters and gutters all need occasional attention, and a tank system that gets ten minutes twice a year has far fewer emergencies than one that gets none.

What tank and pump work costs

Pump repairs are usually a modest job. New installations depend heavily on the site.

On acreage we would rather look at the whole setup once than fix the same symptom three times. Tank systems are usually a chain of components, and the weakest link is often not the one that failed.

Questions

Tank and pump questions

Check that it has power and that the circuit breaker has not tripped, because that accounts for a decent share of these calls. Check the tank actually has water in it. If the pump is humming but not delivering, it may be air-locked or the suction side may have lost water. Beyond that, do not start dismantling a pump that is connected to power. Call us.
That is called cycling and it nearly always means one of two things: a small leak somewhere in the pressurised side losing pressure and triggering the pump, or a problem with the pressure switch or the pressure vessel. It is worth fixing quickly, because constant starting and stopping wears a pump out much faster than steady running.
Plenty of households across Sydney's rural fringe do, and have for decades. Whether it is safe at your place depends on your roof, your gutters, your inlet screens, whether the tank has been maintained, and what has been getting into it. NSW Health publishes guidance on rainwater for drinking and it is worth reading rather than taking a plumber's word for it. What we can do is make sure the plumbing, screening and filtration side is set up properly, and tell you if we see something in your setup that we would not drink from.
Sediment builds up in the bottom of any tank over years and it does eventually need dealing with. The more useful maintenance is the stuff that stops material getting in at all: keeping gutters clear, keeping inlet screens intact and in place, and keeping the first-flush and leaf diverters working. A well-screened tank needs cleaning far less often than an unscreened one.
Yes, and it is a common way to get real value out of a tank on a town-water property. It has to be plumbed so that tank water and drinking water supply cannot cross-connect, and the tank supply lines need to be identified correctly. It is licensed plumbing work for that reason.
It depends on how far and how high the water has to travel, how many outlets might run at once, and what pressure you want at the tap. This is the most common thing that gets specified badly, and the result is a house with disappointing pressure and a pump working too hard. We will size it against your actual property rather than guessing.
Where there is a town water connection available, yes. It has to be done with proper protection so tank water can never flow back into the town supply. Done correctly it means you stop worrying about running dry in a dry spell.
On rural and bushfire-prone blocks there are often requirements about static water supply and fittings for firefighting access, and those requirements come from the planning and bushfire rules for your property rather than from us. Tell us what your property is required to have and we will do the plumbing to suit it. Do not take a website's word for what your block needs, because it varies and it matters.
Very often that is a blocked filter, a partly closed valve, a blocked tank outlet screen, or an undersized supply line rather than the pump itself. This is why we look at the whole path rather than going straight to the pump.

Tank water on Sydney's rural fringe

There are two completely different conversations about rainwater tanks, and which one applies to you depends on whether you have a town water connection.

If the tank is a supplement

On a suburban block with town water, a tank is about reducing what you buy from the mains. Garden and lawn, toilets and laundry are the usual uses. The plumbing has to keep tank water and drinking water properly separated, and the value of the whole thing depends on the tank actually filling, which means the catchment plumbing and diverters need to work. A tank that has not filled properly in two years is decoration.

If the tank is the water supply

On unsewered acreage through Dural, Kenthurst, Annangrove and Glenorie, and on bush blocks without a town water connection, the tank is the household water supply. That changes everything. A failed pump is not an inconvenience, it is a house with nothing coming out of any tap. Water quality matters because people are drinking it. Running dry in a dry spell is a real risk that needs planning for, whether that is storage capacity, a mains backup where one is available, or carting water.

These properties also tend to have systems that have grown organically over decades: a tank added here, a pump replaced there, filters someone fitted in the nineties, and a run of pipe up a hill that nobody has ever calculated. When we get called out for low pressure, the fault is very often not the component the owner suspects.

The pump is usually not the problem

Pumps get replaced unnecessarily all the time. Before condemning one we check the pressure switch, the pressure vessel, non-return valves, the suction side, and whether there is a small leak somewhere in the system quietly triggering it to cycle. Those are cheaper fixes and they are frequently the actual answer. Where a pump genuinely does need replacing, sizing it correctly for the distance and height it has to push water is the part that determines whether you are happy with it.

The maintenance that prevents callouts

Keep the gutters clear, because everything on the roof ends up in the tank otherwise. Make sure inlet screens are actually in place and intact, because that is what keeps leaves, insects and animals out. Check that first-flush and leaf diverters are not blocked. Change filters when they need it rather than when the pressure has already dropped. That is twenty minutes twice a year, and it is the difference between a tank system that just works and one that surprises you.
