If you’ve noticed water pooling around your solar hot water system, it’s easy to assume the worst. But a leak doesn’t always mean a major failure — sometimes it’s a sign your system is doing exactly what it’s designed to do. That said, it’s important to understand the potential causes of leaks so you can act quickly and avoid long-term damage.
At Todd’s Plumbing & Electrical, we’ve been helping homeowners across the Gold Coast with their hot water systems for over 20 years. Let’s break down the most common reasons your solar hot water system might be leaking — and what to do about it.
Most solar hot water systems are fitted with a pressure and temperature relief valve (PTR valve). This valve is designed to release small amounts of water during the heating cycle — especially on hot days — to prevent excess pressure building up.
What to look for: Occasional dripping from the valve during the day.
What to do: This is normal. But if the dripping becomes constant or heavy, it could be time for a replacement valve.
Over time, pipes exposed to the elements can crack or corrode — particularly in older systems or those not regularly serviced.
What to look for: Continuous leaks, rust stains, or greenish corrosion around joints.
What to do: This should be checked by a qualified plumber right away to avoid further water loss or damage.
If your storage tank is leaking from underneath, it could indicate internal corrosion or a failed tank lining. Unfortunately, this usually means the tank is nearing the end of its life.
What to look for: Pooling water under the tank or damp insulation.
What to do: Contact a licensed plumber — you may need a replacement tank or a full system upgrade.
Leaks can also come from worn-out rubber seals or loose connections around the system’s valves and pipe fittings.
What to look for: Drips at joints or where pipes meet the tank or solar collectors.
What to do: Seals may need to be replaced, or connections re-tightened by a technician.
In colder parts of the hinterland or after a heavy storm, your system may experience damage from ice or wind-blown debris.
What to look for: Cracked panels, disconnected pipes, or leaks after extreme weather.
What to do: Call your local plumber to assess and repair the damage.
Even small leaks can lead to bigger problems, like water damage, high energy bills, or system failure. Regular servicing from a local expert can keep your solar hot water system running efficiently and extend its lifespan.
