I have recently moved in to a new house and have inherited a pond 8ft x
6ft x 4ft deep.
The pond is constructed of cement/brick and I have noticed that the
water level is dropping by some 4 inches overnight and then levels out,
obviously a leak.

Once the leak lowers the level to a hole and then the rate of loss
drops off, you will have established the aproximate depth of the
leaks. Add enough water to raise the pond level back up an inch or so.
Move around the pond with a dropper and use milk to track where the
flow passes through the wall. You can patch with any number of cements
or expoxies which work when wet.
Ultimately you may be forced to empty the pond and line it with EPDM
rubber or some other resealing technique.
