When the taps run cold, start here
Before anything else, confirm it is genuinely the system and not a supply issue. Run the hot tap at the kitchen sink and in the bathroom, and check whether the cold water is flowing normally. If the whole house has no water, the fault sits upstream of your hot water unit entirely.
If the tank itself is leaking, act now. Shut the isolation valve on the inlet pipe, cut the power supply to the unit at its isolator, and keep everyone clear of the water. A tank that has split cannot be patched, and every hour it drains is water on your floor.
The usual suspects, in order of cost
Not every cold tap means a dead unit. Working through the likely causes from least to most expensive saves you from assuming the worst:
- Tripped switch or blown element On electric systems, check the circuit breaker and the isolating switch near the unit first. A failed element or thermostat is one of the more affordable repairs going.
- Pilot light out Gas storage units with an extinguished pilot can often be relit following the manufacturer's instructions on the unit. If it will not stay lit, the thermocouple is the usual offender.
- Failed valve or thermostat Water that runs lukewarm rather than cold often points to a tempering valve or thermostat, both fixable without touching the tank.
- The tank itself Rusty water, a leaking casing or a unit original to the house usually means the tank has finished its working life, and hot water repair gives way to replacement.
What you can safely check yourself
A few minutes of safe checking tells you, and us, a lot before the van arrives:
- Look at the meter box and isolator for a tripped hot water circuit, and reset it once.
- Find the unit and check for water pooling underneath or rust streaks down the casing.
- On a gas unit, see whether the pilot light is burning and whether it stays lit.
- Note the unit's age from the compliance plate, because a decade-plus tank changes the repair conversation.
Never open a powered cover, work on gas fittings or attempt to drain a tank yourself. Those are licensed jobs, full stop.

When to stop checking and call us
Some faults end the troubleshooting immediately. Treat any of these as your signal to ring:
- The tank is leaking from the casing, or water is pooling faster than you can wipe it up.
- You smell gas anywhere near the unit or its supply line.
- The relief valve is discharging continuously rather than in short bursts.
If the system is simply silent and cold with no visible fault, it is still worth calling the same day, because a failed element left unattended can sometimes take the thermostat with it.
And if the loss of hot water comes with gurgling drains or water backing up, the real fault may be downstream, in which case our drainage specialists are the right people.
What we do when we arrive
Diagnosis comes first, and it is honest. We test the element, thermostat, valves and, on gas units, the thermocouple and burner, then tell you plainly whether the fix is a component or a tank.
You get one fixed written price before any work starts, and if replacement is the better answer we size the new unit to your household rather than selling you the biggest box on the van.
Every replacement is commissioned properly, with the compliance certificate lodged and supplied with the invoice.
Call and tell us
Ring (02) 9072 0504 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
Fix, test and commission
We isolate the failed component or drain the dead tank, complete the repair or swap-in, then test the full system: inlet pressure, outlet temperature at the tap, relief valve operation and, on gas, the flue and connections, so the unit leaves the visit running to specification.
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Westleigh
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Westleigh works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
The streets we cover beyond your door
Our work covers the ridge itself and the neighbouring suburbs: Cherrybrook, Normanhurst, Hornsby and Pennant Hills, with the same licensed team, the same $0 call out and the same fixed-price promise wherever you live in the catchment.
Good questions, straight answers
Hot water questions Westleigh locals keep asking
Why did my hot water stop with no warning?
Storage tanks past their design life often fail suddenly when a heating element, thermostat or valve gives out, and ageing units in long-held homes are the most common culprits we see.
Is a leaking hot water tank an emergency?
Yes, because a leaking tank cannot be repaired and water damage spreads quickly, so shut the isolation valve and the water supply, then call a licensed plumber straight away.
Should I repair or replace an old hot water system?
Failed valves or elements in a reasonably young unit are usually worth repairing, while a leaking, rusting or original-era tank is generally better replaced, and we quote both options honestly.
Can you replace a hot water system the same day?
For a like-for-like swap we can usually remove the old unit and commission the new one in a single visit, confirming the fixed price in writing before any work begins.
Do you work on gas and electric systems?
Yes, our licensed plumbers repair and replace gas storage, electric storage and continuous-flow systems, and we handle the compliance certificates your installation requires.
Why do hot water systems fail more often on the ridge?
Homes here were largely built from the late 1960s through the 1980s, so many tanks are in their first or second generation, and cooler winters at elevation make them work harder than coastal systems.
