A real person answers, day or night

When repairing stops making sense

Every system reaches the point where the next repair is money poured into a unit already on borrowed time. Rusty hot water at the taps, or a heater needing a new part every winter, tells you the end is close. We replace systems across the suburb every week.

Do not wait on this

The towers are cycling through replacements right now

  • Forum Tower was the suburb's first high-rise, completed in 1999, and everything built in that late-1990s wave around the station is now twenty-five years on.
  • Central plants and individual units across those buildings are hitting the end of their design life in waves, so whole floors of the same tower often replace within a year or two of each other.
  • We know the access routines, the riser layouts and the building managers, which is why strata replacements here run smoothly instead of dragging.

What we replace

Gas storage systems. Many of the pre-1940 brick cottages on the southern streets have run gas hot water for decades on original supply lines, so we assess those older fittings for compliance before connecting a new tank, then size the replacement to the household's actual morning demand.

Electric tanks. Units and older apartments near the UTS campus and the station commonly run compact electric tanks tucked in laundries or cupboards, and we swap them like-for-like or upsize where a household has grown, checking off-peak wiring as we go.

Continuous flow units. Instant gas systems suit compact local apartments beautifully because they free the whole cupboard wall and never run cold mid-shower, and we upgrade gas runs and fluing where an older storage unit is coming out in their favour.

Apartment and strata replacements. Replacing systems across the towers built from the Forum era onward means booking a window with the building manager, isolating the correct riser and protecting shared corridors, and we document every step so the owners corporation has a clean paper trail.

Access, timing and the weather on the ridge

The ridge works systems harder

Towers here cop strong western afternoon sun, pushing summer cooling loads up, and reverse-cycle and hot water demand run year-round in the apartment stock, so a marginal system rarely gets a gentle off-season.

Timing matters too

Replacement in a tower needs a booked access slot with the strata manager, and we schedule around it rather than leaving a household cold for days waiting on approvals.

Signs the tank is finished

Rust in the water

Brown or metallic-tinted hot water means the tank lining has failed and the steel inside is corroding, and once rust shows through the fittings the tank is living on weeks, not years.

Water where it shouldn't be

Moisture at the tank base or a slow drip from the valve housing points to internal failure rather than a loose fitting, and a weeping tank cannot be repaired, only replaced.

Repairs stacking up

A new element one winter and a thermostat the next shows the whole unit is tired, and two or three call outs in as many years usually cost more than the replacement they were delaying.
Cutting pipe to length on site

Why it matters before winter

Cold mornings arrive fast

A tank that limps through September rarely survives July, and replacing on your schedule with a fixed quote beats an emergency swap-in at the worst possible hour.

Leaking tanks damage

A failed unit in an apartment dumps water into a cupboard, a corridor or the ceiling below, and the water damage routinely costs more than the replacement would have.

New systems cost less to run

Modern units heat more efficiently and waste less standby heat, so a properly sized replacement pays you back quietly every quarter for the life of the unit.

How it works

Our replacement process

  1. 01

    Call and tell us

    Ring (02) 9072 0528 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.

  2. 02

    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.

  3. 03

    Swap, test and commission

    We isolate and drain the old unit, disconnect the services, remove the tank from the property, then fit and connect the new system, checking pressures, tempering, fluing and safety devices before running hot taps to prove the whole setup works as it should.

  4. 04

    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 St Leonards

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 St Leonards 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.

If the system still has life left in it, see whether hot water repair covers the fault instead, or if you are adding a system to a renovation rather than swapping one out, hot water installation is the right page.

Where we work

Areas we service

From the high-rise precinct around the station we work across Crows Nest, Wollstonecraft, Naremburn, Artarmon and Greenwich, replacing failing systems wherever the lower North Shore needs them. If a sudden failure leaves you cold tonight, our no hot water page handles the urgent side.

Good questions, straight answers

Questions St Leonards locals ask before replacing

How do I know my hot water system needs replacing rather than repairing?

Rusty water, a tank weeping from the base, repeated element or valve failures, and a unit past ten to fifteen years old usually signal replacement is the smarter long-term spend.

How long does a hot water replacement take?

Most like-for-like swaps are finished the same day, while a change of system type, fuel or location can add a day for gas runs, metering or compliance work.

Can you replace systems in apartment buildings?

Yes, we book access with the building manager, isolate the right riser and protect common areas, handling the strata side as part of every tower job.

Should I switch from electric to gas or instant?

If a gas line already serves the property, continuous flow systems free up space and never run out of hot water, and we talk through running costs before you commit.

What happens to my old unit?

We disconnect, drain and remove the old tank or unit, dispose of it responsibly, and leave the installation area clean, tested and ready to use.

Is the work covered by a warranty?

Every replacement carries our Lifetime Labour Warranty alongside the manufacturer's warranty on the new unit, so if our workmanship fails, we return and fix it at no cost.
