Without a pump, the push at a tap depends on how high the tank sits above it. On the foothill lots out along Winn Road that height changes block by block, so plenty of homes hand the job to the pump. Our Cashmere plumbers work through the whole set, from tank to tap.

Pressure Pumps for Tank-Fed Cashmere Homes
A tank pump is a pressure pump: it lifts water out of the tank and feeds it through the house plumbing at a workable push. A pressure switch or controller rides along with it, firing the unit up when a tap opens and winding it down once the taps shut.
Some sets add a small sealed pressure tank beside the pump. That tank keeps a little water under pressure, so light draws like filling a kettle do not wake the motor at all. The sealed tank belongs to the pump set and has nothing to do with the rainwater tank out on the block.

How a Plumber Sizes a Pump for Your Home
Three pump styles cover the field, and where each one sits decides what it suits. A jet unit stands above ground beside the tank and pulls its water up from there. A submersible unit drops into the tank, where the water around it deadens the sound.
A multistage unit stacks its pressure stages for bigger or two-storey homes. Two numbers then drive the sizing: flow first, then head.
Flow means tallying what every outlet draws when several run together. Head means the climb from the pump up to the highest tap, plus the drag the pipe itself adds.
A longer or narrower run of pipe surrenders more push to drag along the way, which counts toward the head. On a slope, with the tank downhill of the house, the climb alone eats metres before the fittings get a look in. Our water pipe repairs work covers the supply lines that feed the pump from the tank.
The local housing makes those sums interesting. At the last census, 87.6 per cent of dwellings here had four or more bedrooms, so several taps at once is a normal evening rather than a rare event. Rainfall averaging around 1120 millimetres a year keeps the tanks worth pumping.

Signs a Tank Pump Needs a Plumber
Short, rapid bursts of starting and stopping are the loudest tell on a failing pump. Watch for any of these alongside them:
- the motor running flat while every tap stays shut
- pressure that goes weak, or swings up and down at the fixtures
- a new rattle, hum or shake from the unit
- water weeping at the pump body or its fittings
The first check costs nothing: look into the tank and see whether any water is left. A dry tank produces every one of those symptoms, and no pump swap fixes a roof that feeds it nothing. Once the tank shows water, we trace the fault on the water side.
A set that cycles with everything shut is the one to chase soon, because the usual driver is a leak somewhere in the line. That hunt belongs to our leak detection service before anyone touches the pump itself.

What Happens When the Tank Runs Empty
A rain-to-mains switch is the device that carries the house across the dry spells. While the tank holds water, the home runs on it. The moment the level bottoms out, the switch flips the supply over to the mains without anyone lifting a finger.
Queensland has one rule on that device worth knowing. Installing, removing or replacing an automatic switching device for a rainwater tank counts as minor work, so a licensee performs the job, and neither a council permit nor a Form 4 follows.
For the tank and everything around it, our rainwater tank plumbing page covers that side of the system. If the kitchen tap should pour cleaner as well, our water filter installation service handles cartridge and housing swaps on the supply.

We assess the whole pump set
We look at where the tank sits, what the controller does each time you turn a tap on, and any cycling, noise or drip you have noticed. On the hillside lots we also check the climb and the run up to the highest fixture, because both shape the pump the house needs.

Tank Pump Questions We Get
Call (07) 3524 0766What does a rain-to-mains switch do?
The switch carries the house through a dry spell. Tank water feeds the home while any remains, and once the tank empties, the switch changes the supply to Unitywater mains automatically. Queensland classes fitting or swapping one as minor work for a licensee.
Which tank pump suits a Cashmere home?
Match the pump to where it can sit and what the house demands. Above ground, a jet unit feeds the lines from beside the tank. Submerged, the same job runs quieter, since the water wraps the motor, and bigger or two-storey places usually take a multistage unit.
What size pump does a house with several taps need?
Size comes from two sums. Tally the flow each fixture draws, in litres per minute, for the outlets that run together, then add the climb to the highest tap and the pipe drag as head. A fixed quote before any work starts locks in the pump those numbers point to.
Where should a tank pump go so it stays quiet?
Inside the tank, where the set-up allows. A submerged motor gets muffled by the water around it, while an outside unit has no buffer and deserves a spot clear of bedrooms and boundaries. We place every pump with the household and the neighbours in mind.
Why does my pump start when no tap is running?
A quiet house should mean a quiet pump, so cycling with the taps shut points to a fault. If a leak sits somewhere in the line, that explains the starts; if not, the switch or the pump itself is worn. We trace the cause on the water side and quote the fix first.
