A failing water tank can leave your property without reliable supply

A leaking or cracked tank drains supply slowly, often going unnoticed until pressure drops or the tank runs dry. On rural and lifestyle blocks where mains water is not an option, this can leave a property without water for washing, drinking or the garden.

Peter Jackson Plumbing repairs and replaces tanks, assesses rainwater harvesting requirements and restores steady flow to taps, hoses and appliances.

Modular rainwater tanks collect and store rain, lowering bills while holding an emergency supply. The slimline design suits narrow sites and expands as demand grows. To discuss the right tank for your property or request a quote, get in touch via the

Modular rainwater tanks sized for your property

Modular rainwater tanks arrive in 1000-litre polyethylene modules with ribbed construction, joined into two-in-one or three-in-one packages as storage demand grows. Capacities range from 1000 litres to more than 5000 litres, so a system can start small and expand without replacing existing tanks.

The modules suit households, cottages, granny flats, beach houses and commercial premises, supplying gardens, laundries, toilets or emergency civil relief storage. During planning, the roof catchment and connection points are checked so capacity matches household use. Various tank colours are available.

Where a rural property needs the pump matched to the tank, arrange this through our water pumps page.

The most slimline water tank available for tight sites

At 750mm wide and 2100mm high, this slimline water tank is among the narrowest available, sitting flat against a wall, fence or boundary where a round tank would not fit.

Standing tall rather than wide, it stores a useful volume down the side of a house without taking up yard space. Before installation, the base is checked for level, access is confirmed and the position is set so the tank drains and connects correctly.

Modules still link on a narrow site, so a tight gap places no limit on capacity. For gardens, stored tank water can feed a greywater system alongside recycled household water.

Water tank pump and pressure systems

Gravity alone rarely produces enough flow to run taps, toilets, hoses and washing machines from stored water. A water tank pump supplies usable pressure, sized to household demand during planning.

Optional pressure or booster pumps and a pump housing unit are available with the modular system. Pressure switches can be fitted so the pump runs only when water is drawn, reducing wear and power consumption.

Where an existing pump has failed, repair may be possible depending on the fault, or a replacement can be quoted separately through our pumps service. Tank water is also commonly heated through hot water cylinder installation.

Water tank installation and ongoing servicing

Certified installation covers siting the tank, levelling the base, connecting inlets and confirming that the system drains and fills correctly. For drinking supply, inlet screens, first-flush diverters and filtration can be fitted, with UV treatment and periodic testing recommended where tank water is the sole source.

Tanks benefit from a clean-out every two to three years to clear sediment that settles on the base, alongside checks of inlet filters, gutter screens and diverters. A servicing schedule can be arranged to cover these checks and pump inspections.

Tank connections often tie into wider site work such as drainage on new subdivisions and rural blocks.

For a typical family home, between 25,000 and 30,000 litres usually works well. The right size depends on how many people live there, daily usage and whether the tank is sole supply or backup. Catchment and connections are assessed during installation.

Yes, a slimline water tank is designed for tight spaces, which suits narrow gaps beside a house or along a boundary. These tanks hold less than round tanks but sit flat against walls. The space is measured and the base confirmed level first.

In most cases, yes. A water tank pump supplies the pressure to run taps, toilets, hoses and washing machines from stored water, as gravity alone rarely gives enough flow. The pump is sized to household demand, with pressure switches fitted so it runs only when water is drawn.

Water storage tanks benefit from a clean-out every two to three years to remove sediment settling on the base. Checking inlet filters, gutter screens and the first-flush diverter regularly is also recommended. Pumps should be inspected for pressure and leaks, and a servicing schedule can be arranged.

Rainwater can be safe to drink with the right filtration in place. Inlet screens, first-flush diverters and filtration systems remove debris, sediment and contaminants before water reaches the taps. Where tank water is relied on for drinking, UV treatment and periodic testing are recommended.
