Plumbing questions from Wolli Creek

It usually depends on where the pipe sits. Damage from a fixture inside your own lot tends to be your responsibility, while a failure in a common wall, riser or shared stack sits with the owners corporation, and we document which one it is so any claim goes to the right party.

Recurring blockages in a tower usually live in the shared stack rather than your own branch line, which is why the same drain keeps backing up after a clear. A camera run up the pipe shows exactly where it sits before anyone pays for the wrong fix.

A lot of the suburb went up quickly through the 2000s, and rushed or low-grade connections and braided hoses were fitted right through the towers. They perish and let go well before you would expect, which is why a burst flexi-hose is one of our most common after-hours calls.

Yes, the towers stand on the low Cooks River floodplain, so a heavy storm surcharges the drains and pushes water toward the lowest levels. We check the basement pump wells, gully drains and non-return valves that are meant to stop stormwater backing up into the car park.

It does, because the reclaimed floodplain holds groundwater within a metre or two of the surface. Below-ground pipework and basement drainage run under constant pressure, so any weak or cracked joint tends to weep or draw groundwater straight in.

Centralised hot water plant that serves many units is common-property work, handled through the owners corporation and its committee, while a system inside your own unit is your call. We can service or replace either one once building access is arranged.

Because the suburb sits barely above the tidal river, the local stormwater network fills quickly in a heavy downpour. Water then pushes back through the lowest gully and floor drains first, so ground-floor units and basements feel it long before anyone upstairs.

Fat and grease washed down dozens of kitchens cools and sets on the walls of the shared vertical stack, slowly narrowing it until waste stops clearing. Jetting the full stack scours it back to size, where snaking a single unit barely touches the problem.

Yes, we trace concealed leaks with acoustic and pressure testing before anything is opened up, so we cut into only the spot that genuinely needs it. That spares you a demolished bathroom wall chased on a guess.
