Our rainwater tank plumbing service in Melbourne

Our licensed plumbers supply, install and repair rainwater tanks, including collection systems, pumps, filters and pipework. We help you choose a tank that suits your roof catchment and how you want to use the water, then we find a practical location so the system works cleanly on your property.

Rainwater tanks are a simple way for families to use less mains water, ease the bill, and look after the garden or the laundry with water you have already collected.

If you already have a tank, we can inspect common faults such as clogged pipes, leaks or a failing pump. Regular attention keeps the system working well and can prevent a small issue becoming a larger repair.

This work sits under our residential plumbing service and under plumbing for home owners if you own the property. Gutters and downpipes that feed the tank are covered on our guttering and downpipes page. A leaking roof nearby belongs with roof leak repairs. If water is uncontrolled or sewage is involved, treat it as 24/7 emergency plumbing.

Call 1300 575 862 when you would like advice on installing or repairing a tank, and we will talk through what we can do for your site.

Signs your rainwater tank needs a plumber

A rainwater tank should quietly collect, store and supply water for years, so it is easy to overlook until something goes wrong. Knowing the early warning signs helps you call a rainwater tank plumber before a small fault becomes an expensive one. The usual signs are a tank that empties too quickly or never fills, damp around the base, weak tank-fed pressure, discoloured or smelly water, and overflowing gutters near the tank.

It may be time to book a service if you notice any of the following:

  • The tank empties faster than usual, or never seems to fill even after solid rain, which often points to a leak or a blocked inlet.
  • Damp patches, mould or pooling water around the base of the tank or along connected pipework.
  • Weak or inconsistent pressure from tank-fed taps, the garden or the toilet, usually a pump or filter issue.
  • Discoloured or smelly water, which can signal a failed first-flush device, a cracked lid or a screen letting debris and pests in.
  • Overflowing gutters or downpipes near the tank, where water is not being directed into the tank properly.

Because tanks are often tied into your roof drainage, a problem here can quickly become a wider water issue. If you are also seeing water marks on ceilings or walls, it is worth having your guttering and downpipes and roof leak repairs checked at the same time, since these feed the tank and share the same fall and flow. A blocked drain that sits near the overflow can also affect how water leaves the property.

Rainwater tank installation and plumbing we handle

Every property is different, so our rainwater tank installation service starts with the right tank in the right place, then a clean, compliant connection to your home. As a licensed rainwater tank installer, we plan the layout, size the system to your roof catchment and household use, and make sure overflow and mains top-up are set up correctly.

We regularly supply, install, connect and repair:

  • Slimline, round, under-deck and modular tanks for homes with limited space.
  • Larger residential and light commercial tanks for gardens, sheds and rural blocks.
  • Pumps, pressure systems and controllers so tank water reaches your taps, toilets and laundry reliably.
  • First-flush diverters, leaf screens and filtration to keep stored water cleaner.
  • Inlet, outlet, overflow and mains-switch plumbing, plus connection of the tank to toilets, laundry and outdoor taps where permitted.
  • Rainwater tank repairs, including leak sealing, pump replacement, blocked pipe clearing and re-plumbing of older or poorly installed systems.

If you are choosing between a brand-new setup and reviving an existing tank, we will give you honest advice either way. We can also coordinate related work such as new downpipe connections or clearing a blocked drain that is affecting how water moves around your property. Broader plumbing services in Melbourne sit on the same site if you need more than the tank.

How our rainwater tank installation works

Our aim is a straightforward, tidy job, whether you need a plumber to install a water tank or a repair on the one you already have. We keep the process simple and keep you informed at each stage.

  1. Site assessment. We look at your roof catchment, available space, ground conditions and how you want to use the water, then recommend a suitable tank type and size.
  2. Clear written quote. Before attending, we will clearly explain the initial cost for the first half-hour. During this time, we will aim to make the situation safe, prevent further damage where possible, and assess the cause of the problem. As every plumbing issue is different, an accurate quote may not be possible until we have inspected the job. We will discuss our findings, explain the available options, and provide a quote before carrying out any further work.
  3. Installation or repair. A licensed plumber prepares the base and connection points, sets and levels the tank, then connects inlets, overflow, pump and any internal plumbing correctly.
  4. Testing and handover. We check for leaks, confirm flow and pressure, and make sure overflow and any mains top-up work as they should before we tidy the site.

Because tank plumbing is licensed work in Victoria, we provide a compliance certificate where the work requires it. You can confirm our licence through the Victorian Building Authority. Every job is backed by our 12-month workmanship guarantee. Joniec Plumbing has served south east Melbourne since 2005, and our 600+ five-star Google reviews reflect the standard we hold ourselves to on every visit.

Often, yes. Many rainwater tank problems come down to leaks, a failing pump, blocked pipes, worn screens or filters, or plumbing that was not connected well in the first place. We inspect the tank and its pipework, tell you honestly whether a repair or a replacement is the better value, and carry out rainwater tank repairs backed by our 12-month workmanship guarantee.

The right size depends on your available space, your roof catchment area and how you plan to use the water, whether that is the garden only or toilets and laundry as well. During the site assessment we weigh these up and recommend a tank that balances capacity with the space you have, including slimline options for narrow side passages. The aim is a system that suits how you use water and helps you save on mains supply.
