A real person answers, day or night
A toilet that misbehaves rarely fixes itself
That soft refill at two in the morning is water running through your meter without permission. We trace the fault to the inlet valve, the outlet washer or the pan seal underneath, then complete the repair on the spot wherever the part is on the van.
If the bowl is overflowing right now, toilet overflowing covers the urgent steps first.

What we repair on a toilet
Most toilet faults sit in a handful of components, and repairing the failing part properly beats resetting the problem for another month: here is what we fix, and how each repair leaves your bathroom working the way it should again.
Running cisterns
An inlet valve that never seals shut or a float sitting too high lets water trickle into the pan around the clock, so we fit a new valve, reset the level carefully and leave the cistern completely silent between flushes.
Leaking pan seals
Water pooling at the base of the pan means the seal underneath has hardened or failed, and we lift the pan carefully, fit a fresh seal and reset it level so the leak stops and the floor stays dry again.
Loose or rocking pans
A pan that rocks on its collar cracks the collar eventually, so we re-seat the fixings, check the bowl for fractures and replace seats, lids and buttons where decades of age have won the argument with the original plastic fittings.
Weak or fading flushes
Poor flush performance usually traces to a water level set below the marked line, a partly blocked trap or a worn mechanism, and we correct the actual underlying cause so a single flush genuinely clears the bowl again every time.
Seized isolation valves
The small stop tap behind the pan seizes or weeps after years of sitting untouched, so we replace it with a serviceable modern valve that gives you a working shutoff the next time the cistern or the supply line misbehaves.

The faults we see most often
- The cistern that never stops A cistern topping itself up between flushes usually means the inlet valve has scaled with sediment or the float sits badly, a small repair today and a serious water bill if ignored, so we replace the valve during the same visit.
- The slow weep at the base A slow seep where the pan meets the floor usually means a hardened seal, common in houses with original bathroom layouts, and re-seating the pan on a fresh seal stops moisture spreading into the bearers below the tiles.
- The flush that fades A weak flush on an older installation often comes down to a cistern filling below its marked line or sediment narrowing the trap passage, and we reset the fill level or clear the passage to restore full performance.
Why a small toilet fault deserves a quick call
A running or leaking toilet is a slow leak against your budget and your bathroom:
- Water bills climb quietly A cistern left trickling wastes thousands of litres across a year, and the meter records every litre of it.
- Floor damage spreads unseen A weeping pan seal soaks into timber bearers and tile grout, and the repair that costs a seal today becomes flooring and carpentry later.
- Small faults grow inconveniently A washer that weeps this month jams the flush entirely next month, usually on a Sunday night when the whole household needs the bathroom at once.
How it works
How the repair runs, step by step
- 01
Call and tell us
Ring (02) 9072 0520 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.
- 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.
- 03
Repair and re-test
We isolate the water, replace the failed valve, washer or seal, and reassemble the cistern to the manufacturer's settings, then run a full fill and flush cycle while watching every joint, so the repair is proven working rather than assumed fixed.
- 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 Thornleigh
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 Thornleigh 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.
Because a toilet repair sometimes reveals a bigger job, we quote any follow-on work separately: if the cistern is beyond saving, toilet installation covers the full swap, and bathroom plumbing handles the wider fixture renewals. The everyday upkeep that prevents these faults in the first place sits under maintenance plumbing.
Where we work
One team, five neighbouring suburbs
One licensed crew covers Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga alongside this suburb, with the same stocked vans, the same fixed pricing and the same warranty, so a running cistern in Wahroonga gets the treatment a ridge-side home expects.
Good questions, straight answers
Toilet repair questions locals ask us
How much does a toilet repair cost?
The call out is $0, your plumber inspects the cistern or pan, and you receive one fixed written price covering the complete repair before any tool comes off the van.
Can a running toilet waste much water?
A cistern left trickling can waste thousands of litres across a year, so a running toilet is worth repairing promptly rather than leaving it to worsen quietly over the months.
Do you repair the older toilets near the station?
Yes, the Federation and weatherboard houses near the railway station often run older cisterns, and we source compatible washers, valves and mechanisms so ageing fixtures keep working without a full replacement.
Can you repair a toilet the same visit?
Usually, because our vans stock the common cistern valves, inlet fittings, seals and washers, so most running, leaking and loose toilet faults are fixed during the first visit without a second trip.
Should I repair or replace my toilet?
A repair suits a cracked washer, worn valve or leaking seal, while a cracked pan or a cistern that keeps failing usually makes replacement the more economical answer over the long term.
Do you service suburbs near Thornleigh as well?
We cover Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga with the same licensed team, the same $0 call out fee and the same fixed written price before any work begins.
