The process is powered by the water pressure
in the leaking pipe, so running costs are low.
It’s not reliant on leak noise or prior knowledge
of the pipe route to deliver extremely accurate leak locations.

1. Deflated

A robust balloon called the Ferret is put inside the leaking water pipe. It is attached to the main system by a 50m long umbilical cord
and then 
deflated so the water in the pipe can get past it to the leak.

2. Inflated

 

The Ferret is then inflated with water. When the pressure
in the Ferret is higher than in the leaking pipe, it blocks
the pipe. No water can get past it to the leak.

3. Moving

 

The pressure inside the Ferret is reduced. When the
right balance is reached between the pressures
in
the Ferret and the leaking pipe, the water in the
pipe
pushes the Ferret towards the leak.

Pipe Tracing 

and Mapping

The Ferret has line tracing and a 33kHz sonde for end tracing built in. In addition, there are distance marks at
1m intervals on the umbilical cord.

 

The line of plastic pipes can be mapped. There is a
simple way to calculate the dig depth to the sonde;
no depth measurement facility is required on the pipe tracing 
equipment to do this.

 

The Ferret locates leaks to within a few millimetres.

4. Automatic Leak Location

 

When the Ferret passes a leak, some of the water
in the pipe escapes through the hole. The pressure
force pushing the Ferret drops so that the Ferret 
automatically stops moving.

The Ferret can be inserted into the leaking pipe through certain types of meter
box without the need for an excavation.

 

A range of fittings are available for quickly connecting the Ferret Leak Locator to the leaking pipe.

Robust design with working pressure from 0.5 to 6.0 Bar.

 

Different sizes for pipes with internal diameters ranging from 10mm to 45mm.

 

The Ferret can pass easily through most types of fitting
such as couplers and tees.
