    Common Toilet Problems We Repair Daily

    1.

    Toilet Constantly Running

    Usually caused by:

    • Worn outlet washer
    • Faulty inlet valve
    • Damaged flapper seals

    Running toilets waste thousands of liters per year.

    2.

    Leaking Toilet at the Base

    Often due to:

    • Worn wax ring
    • Damaged pan collar
    • Cracked outlet
    • Incorrect installation

    Left too long, leaks cause structural floor damage.

    3.

    Toilet Won’t Flush Properly

    Caused by:

    • Cistern faults
    • Blocked trap
    • Broken flush mechanism
    • Low water levels
    4.

    Weak or Partial Flush

    Often a sign of:

    • Blocked rim jets
    • Faulty dual-flush mechanism
    • Build-up inside the toilet
    5.

    Noisy or Hissing Toilet

    Indicates:

    • Faulty inlet valve
    • High pressure
    • Sediment blocking the valve
    6.

    Cracked Toilet Bowl or Cistern

    A crack needs immediate replacement — it can result in sudden flooding.

    7.

    Blocked Toilets

    One of Sydney’s most common emergencies.

    We clear blockages quickly and safely.

    8.

    Loose or Wobbly Toilet

    This is caused by:

    • Loose bolts
    • Damaged flange
    • Rotten flooring
    • Incorrect initial installation

    We stabilise and reseal it properly.

    Signs Your Toilet Needs Immediate Repair

    • Water around the base
    • Dripping sounds when it’s not being used
    • Toilet constantly running
    • Bad smells coming from the toilet
    • Cracks in the bowl or cistern
    • Toilet moving when you sit on it
    • Weak flush
    • Bowl doesn’t refill correctly
    • Water hammer when flushing
    • Stains on the floor around the toilet

    If any of these are present, you need repairs urgently.

    • More than 15–20 years old
    • Heavily stained
    • Cracked or damaged
    • Poorly designed
