Why rainwater tanks leak

A leaking rainwater tank wastes the water you have collected and can undermine the tank base, so it is worth fixing promptly. Tanks leak from several points, and finding the exact source is the first step:

The outlet, tap or fitting, where a seal or connection has failed
A crack in the tank wall or base
A failed seam or joint on the tank
The connected pipework to the home or garden
The pump and its connections

A leak at a fitting is usually a straightforward repair, while a cracked tank may need more. We locate the source and repair it across Brisbane, Perth and Adelaide.

Leaking outlets, taps and fittings

The most common source of a rainwater tank leak is a fitting, the outlet, the tap, or a connection, where a seal or washer has perished or a fitting has worked loose or corroded. These are usually straightforward repairs, replacing the fitting, seal or washer, or resealing the connection, and they stop the leak without touching the tank itself. A leak at the outlet or tap is often what people notice first, water weeping or dripping from the fitting. We check and repair the outlets, taps and fittings, replacing worn parts and resealing connections, so the leak is stopped. Often a leaking tank is simply a failed fitting, which is an affordable, quick fix.

Cracked tanks

Sometimes a tank leaks because the tank wall or base is cracked, from age, UV degradation (on some plastic tanks), ground movement, or impact. Whether a cracked tank can be repaired depends on the tank and the crack, minor cracks in some tanks can be repaired, but a badly cracked or deteriorated tank may need replacing, as a failing tank will keep leaking and worsen. We assess the crack and the tank and advise honestly whether a repair is viable or replacement is the better option. If the tank is near the end of its life or badly cracked, replacing it is the lasting solution. We will give you a straight assessment rather than attempting a patch that will not hold.

Water pooling under the tank

If you notice water pooling or the ground staying wet under or around your rainwater tank, it points to a leak, from the tank base, the outlet and fittings at the bottom, or the connected pipework running from the tank. A leak at the base is a concern because, as well as wasting water, the escaping water can erode and undermine the tank’s base or stand, which over time can affect its stability, a serious issue for a heavy full tank. We investigate pooling under the tank to find whether it is the base, a fitting, or the pipework, and repair the source. Addressing a base leak promptly protects both your water and the stability of the tank.

Pump and pipework leaks

Not every rainwater tank leak is the tank itself, the pump and the pipework connecting the tank to your home or garden are common sources too. A tank pump has connections and seals that can leak, and the poly or other pipework running from the tank to the house, taps, or irrigation can crack, develop failed joints, or leak at fittings. A leak here wastes water and can affect the pump’s operation. We repair leaks in the tank pump and its connections, and in the connected pipework, so the whole system, not just the tank, holds water and works properly. If your leak is at the pump or in the pipework rather than the tank, we can find and fix it.

Finding the exact source

Because a rainwater tank leak can come from the tank, a fitting, the pump, or the pipework, we take the time to find the exact source rather than assuming. We check the outlets, taps and fittings, inspect the tank for cracks and failed seams, check the pump and its connections, and examine the connected pipework, observing where the water is actually escaping. This matters because the fix differs, a fitting repair, a tank repair or replacement, a pump repair, or a pipework repair. Once we have pinpointed the source, we carry out the right repair and confirm the leak is stopped. Accurate diagnosis means we fix the real cause, not just the first wet spot we see.

Why fix a leaking tank

A leaking rainwater tank is worth fixing for a few reasons. First, it wastes the water you have collected, which defeats the purpose of having a tank and, in dry times or on tank water, is a real loss. Second, a leak at the base can undermine the tank’s stand or footing, risking the stability of a heavy tank. Third, a small leak, from a fitting or a crack, tends to worsen over time. Fixing the leak preserves your collected water, protects the tank, and stops a minor problem becoming a bigger one. Given that most tank leaks are affordable fitting repairs, it is well worth addressing rather than letting your water, and potentially your tank, go.

Rainwater tank maintenance

Looking after your rainwater tank helps prevent leaks and keeps it working well. Periodically checking the outlets, taps and fittings for weeping or corrosion catches leaks early, while they are easy fixes. Keeping the tank and its stand or base sound, and the pump and pipework in good order, prevents bigger problems. Checking the inlet, gutters and leaf screens keeps the water clean and the system flowing. If you rely on your tank for household or garden water, a periodic check keeps it reliable. We can inspect your tank, fittings, pump and pipework as part of fixing a leak or as maintenance, and advise on keeping your rainwater system in good condition.

Tank water supply issues

Alongside leaks, rainwater tanks can have supply issues, no water coming through, low pressure, or the pump not working properly, which are often related to the pump, the pipework or the fittings rather than the tank itself. A leak in the pipework or at the pump can cause pressure problems, and a faulty pump means no supply. We can diagnose and fix tank supply problems as well as leaks, repairing or advising on the pump, clearing or repairing the pipework, and sorting the fittings and connections. If your tank is leaking and also not supplying water properly, the two may be related, and we can address both, so your tank both holds water and delivers it to the house or garden.

How much does it cost?

The cost of repairing a leaking rainwater tank depends on the source, a leaking outlet, tap or fitting is an affordable repair, while a cracked tank needing replacement, or extensive pipework or pump work, costs more. We locate the source first, so we can give you an accurate upfront fixed price for the actual repair needed, rather than guessing. For a simple fitting leak, it is a quick, inexpensive fix; for a failing tank, we will advise honestly on repair versus replacement and quote accordingly. We explain the options and costs clearly, so you can decide the best way to stop the leak and preserve your collected water.
