Solar Hot Water Repair Services We Provide in Melbourne

Solar Hot Water Leak Repairs
Water leaking from your roof-mounted system, dripping down the wall, or pooling around the tank? We trace the leak to its source and repair it properly: collectors, valves, fittings or pipework.

Frost Valve Replacement
A worn or stuck frost protection valve is the single most common winter call-out we get. We replace it with the correct valve for your system and check the rest of your frost protection while we're up on the roof.

Leaking Solar Panel & Collector Repairs
Cracked, leaking, or frost-damaged rooftop collectors assessed on the spot. Where a panel can be saved, we'll repair it; where it can't, we'll talk you through a bypass or replacement before any work starts.

Frost Damage Diagnosis
Woke up to water running off the roof after a frost? We diagnose whether it's a frost valve doing its job, a valve that's failed, or a collector that's cracked, so you know exactly what you're dealing with.

No Hot Water Repairs
No hot water, or water that never gets properly hot? We check the tank, booster, sensors and pipework to find why your solar hot water system has stopped delivering, and get you back into hot water fast.

Solar Hot Water System Inspection
A full plumbing inspection of your collectors, frost valve, tank, booster and pipework, ideally before winter, to catch worn valves and weak points before they turn into a burst panel.

Solar Hot Water Frost Damage & Leaking Repairs in Melbourne
This is the part most plumbers skip, and the part that matters most once the cold sets in. If you’ve spotted water running off your roof from the solar collectors, here’s what’s happening and what to do about it.
Is it your frost valve, or a cracked collector?
These are the two usual culprits, and they're very different jobs. A frost protection valve is designed to drip when the temperature near it drops to around 3-4°C. It bleeds a little warm water through the collectors so they don't freeze, so dripping on a frosty morning is normal. What isn't normal is constant leaking, water spraying rather than dripping, or water flowing on mild days. That points to a valve that's stuck open or worn out, or a collector that has already cracked from a previous freeze. A licensed plumber can tell the difference quickly.
How frost valves fail
Frost protection valves don't last forever. They typically last only a year or two before the internals wear, and they stop sealing. A failed valve does one of two things: it floods your roof and spikes your water bill, or it quietly stops protecting the collectors, leaving them exposed to the next freeze. Caught early, replacing it is a straightforward, affordable fix, which is exactly why a quick pre-winter check pays for itself.
When a panel can be repaired vs when it needs a bypass or replacement
If a system freezes (because the valve failed or was never fitted), the collectors can crack internally where you can't see it, then leak the moment they thaw. Frozen, split collectors usually can't be repaired. In that case we'll either bypass the solar collectors and keep you running on the booster, or replace the affected panel or system. We'll give you the straight call on repair versus replace before we start.
Leaking from the roof right now? Do this first.
Shut off the isolation valve on your hot water system (the tap on the cold water line feeding the unit). If you can't find it, turn off the water at your mains meter. That stops water running off your roof. Then call a licensed plumber. Don't climb onto a wet, frosty roof yourself.
Why a licensed plumber is the right next step
Solar hot water leaks are plumbing faults: valves, collectors, tanks, boosters and pipework. A licensed plumber can legally and safely work on the system, diagnose the real cause rather than guess, and either repair it on the spot or tell you honestly when replacement is the better value. It's not a job for a solar power installer or a DIY trip up a frosty ladder.

Leaking Solar Hot Water Panels
Why Solar Hot Water Panels Leak in Winter
Melbourne isn’t officially in Victoria’s frost zone, but anyone in the outer suburbs knows better. On clear, still nights, the temperature near your roof collectors can drop below freezing, and that’s exactly when solar hot water systems start leaking.
When water inside the rooftop collectors freezes, it expands. That expansion is enough to crack copper risers, split a manifold or burst a panel, damage that’s often impossible to repair and expensive to replace. Most systems have a frost protection valve to prevent it, but those valves wear out, and when one fails, the freeze damage follows.
It’s worst in Melbourne’s cooler, elevated pockets: Melton, Sunbury, Craigieburn and Whittlesea in the north and west, the Dandenong Ranges and Yarra Valley in the east, and the Macedon Ranges. But we see frost-related leaks right across the metro every winter.
How We Repair Solar Hot Water Systems

Find the Real Cause
We inspect the collectors, frost valve, tank, booster and pipework to work out exactly what's failed (valve, panel, tank, booster or pipe), not just where the water's coming out.

Fix It or Quote It Straight
Where it's a repair, we carry the common parts to fix it on the spot. Where it's a replacement, you get a clear, itemised quote before any work begins.

Test and Protect for Next Winter
We test the system end to end and check your frost protection is doing its job, so you're not back in the same spot next cold snap.

Frequently Asked Questions: Solar Hot Water Repairs Melbourne
Why is water leaking from my solar hot water panels?
In winter, it’s most often the frost protection valve doing its job, dripping to stop the collectors from freezing. Dripping only on frosty mornings is normal. If it’s leaking constantly, on mild days, or spraying water, the valve has likely failed, or a collector has cracked from a previous freeze. A licensed plumber can quickly tell which it is and repair it.
Do plumbers replace solar hot water frost valves?
Yes. Frost valve replacement is a standard plumbing job and one of the most common solar hot water repairs we do over winter. We fit the correct valve for your system and check the rest of your frost protection while we’re on the roof.
Is a leaking frost valve urgent?
It can be. A valve dripping lightly on a frosty morning is doing its job, but one leaking constantly is wasting water, pushing up your bill, and may mean your collectors are no longer protected from the next freeze. It’s worth getting it looked at promptly rather than leaving it.
Can a cracked solar hot water collector be repaired?
Sometimes, but often not. Once water freezes inside a collector and splits the internal pipework, the panel usually can’t be repaired. We’ll assess it on site and, if it can’t be saved, talk you through bypassing the collectors or replacing the panel before any work begins.
Do you install electrical solar panels?
No. We’re licensed plumbers, not a solar power company. We don’t install or repair electrical (PV) solar panels. What we handle is the plumbing in solar hot water systems: leaking rooftop collectors, frost valves, tanks, boosters and pipework.
How quickly can you repair my solar hot water system in Melbourne?
For urgent jobs like leaks, no hot water or frost damage, we offer same-day bookings across Melbourne and respond as fast as we can.
Do you repair all brands of solar hot water systems?
Yes. We repair Solahart, Rheem, Edwards, Chromagen, Dux, Apricus, Hills, Rinnai and others, whether or not we installed the system.
Should I repair or replace my solar hot water system?
It depends on the system’s age and what’s failed. A valve, sensor or booster fault is usually worth repairing. Cracked collectors, a leaking tank, or a system past 10 to 15 years often makes replacement the better long-term value. We’ll give you an honest recommendation either way.
