Shared water line leak solution in Burwood
A customer in Burwood contacted Doherty Plumbing Solutions after discovering a water leak between two units that shared the same water supply line. George investigated the problem and found the leak was within a concrete slab.
Repairing the damaged section directly would have required a complicated and expensive excavation.
Instead, George developed a more economical workaround. The affected water supply was bypassed, and a new line was extended over the garage roof to supply the rear unit.
For similar problems, our plumber in Burwood and leak detection service can help identify the issue and determine the most practical repair option.
Quick answer
How did we solve this shared water line leak in Burwood?
The leak was located within a concrete slab between two units sharing the same water line. Repairing the damaged section directly would have involved major concrete work and a more expensive repair.
George instead bypassed the leaking section and rerouted the water supply over the garage roof to the rear unit. This restored the water supply while avoiding unnecessary slab excavation.

The problem
The customer reported a water leak affecting two units that shared the same water supply line.
After investigating the issue, George determined that the leak was located within a concrete slab. A direct repair would have required opening the slab to access the damaged pipe. That meant considerably more disruption, labour and repair work around the property.
Rather than proceeding straight to the most invasive option, George looked for a practical alternative.
What we found
The damaged section of the shared water supply was concealed within the concrete. Because of its location, simply exposing and repairing the leak would have required significant access work.
The job photos show the existing water pipework around the property, the garage roof area and the route used for the replacement supply. This made it possible to plan a new water line that avoided the damaged section entirely.
The workaround solution
George bypassed the leaking section instead of excavating the concrete slab.
A new water supply line was extended up the building and routed across the garage roof before continuing to the rear unit.
This allowed the damaged section within the slab to be taken out of service while maintaining a reliable water supply to the property. It was a more economical and less disruptive solution for the customer.
Why a bypass can be a better option
Not every concealed pipe leak needs to be repaired at the exact point where the pipe has failed.
Where a damaged pipe runs through a difficult-to-access area such as a slab, rerouting or renewing the water line may provide a more practical solution.
The best option depends on where the damaged pipe is located, how difficult it is to access, the condition of the existing pipework, the cost and disruption involved in opening walls, floors or concrete, and whether a suitable alternative route is available.
The result
The leaking section beneath the slab was bypassed, and a new water supply route was installed for the rear unit.
The customer avoided a much larger concrete repair and the additional disruption that would have come with it. George was able to provide a practical solution that restored the water supply while keeping the work more manageable.
What this Burwood job shows
Finding the leak is only part of solving the problem.
In some situations, the most appropriate repair is not necessarily to dig directly down to the damaged pipe. A good plumbing solution should take into account access, disruption, cost and the long-term reliability of the water supply.
This Burwood job is a good example of using a water service bypass to solve a difficult concealed leak.
Frequently asked questions
Can a water pipe leak underneath a concrete slab?
Yes. Water supply pipes can run underneath or through concrete slabs. When these pipes fail, the leak may be difficult to access without opening the concrete.
Does a slab leak always require the concrete to be removed?
No. It depends on the property and the pipe layout. In some cases, rerouting or renewing the water supply may avoid the need to excavate the slab. A plumber needs to inspect the property and determine whether an alternative route is practical.
What is a water supply bypass?
A bypass involves installing a new section of water pipe around the damaged or inaccessible part of the existing line. The new pipe reconnects the water supply without relying on the failed section.
Can two units share one water supply line?
Yes. Some properties have shared water supply pipework. If a leak develops in the shared section, it can affect more than one dwelling and may require careful planning to maintain supply to both properties.
