Isolation Tap under a laundry sink

Imagine this: there’s water pouring out under the bathroom sink, and you’ve got towels on the floor, buckets catching drips — and no idea how to shut it off. In a unit complex, that’s more common than you think.

Whether you’re a tenant or an owner, knowing where your water isolation tap (stop cock) is can save serious stress, money, and damage in an emergency.

Here’s how to find it.


🏢 If You Live in an Apartment (Unit)

Apartment isolation taps can be inside your unit — or hidden away in a shared area. Here’s where to start looking:

🔹 Inside Your Unit

  • Laundry cupboard or under the trough
  • Kitchen sink cupboard
  • Random wall tap, often next to your toilet — this can isolate the whole unit
  • Access panel in your bathroom ceiling

🔹 In Common Hallways or Cupboards

  • Water meter cupboard in the hallway, usually near your front door. Often shared with other units.
  • Access panel in the ceiling of the hallway, close to your unit.

🔹 Riser or Plumbing Shaft

These are vertical shafts behind your bathroom wall, accessible via:

  • An access panel in your bedroom cupboard, or
  • A panel on the hallway or opposite side of the bathroom wall.
    These are usually not locked and give you access to your individual water shut-off.

🔹 In the Basement or Car Park Ceiling (Top-Fed Systems)

Sometimes isolation taps are installed in the ceiling cavity above your car space.
⚠️ Important: These may isolate multiple units, so don’t touch them unless it’s an emergency — or speak with your building manager first.

🔹 In External Laundry Cupboards

If your laundry is separate from your unit, like in older complexes, you may find your isolation tap inside that laundry cupboard — often located behind or near your parking spot.


🏘️ If You Live in a Townhouse

Townhouses are a little more straightforward — but not always!

🔸 Check These Spots First:

  • Near the front hose tap – often right next to your water meter
  • In the ground near your driveway or footpath – look for a plastic or concrete pit

🔸 Other Possible Locations:

  • Inside your garage or laundry, under the tub or near the hot water system
  • On an external wall – usually near the kitchen, laundry, or front of the house
  • In a shared meter pit – in some complexes, your water meter (and isolation tap) might be grouped with others:
    • In a common garden area, or
    • Inside a neighbouring yard

If you’re not sure which tap is yours, check with your strata or building manager.


🔧 Why This Matters

Emergencies don’t give you time to fumble around — burst hoses, overflowing toilets, or leaking taps need to be isolated quickly to prevent water damage, mould, and insurance headaches.

Don’t wait until you’re ankle-deep in water to figure it out.
