We have 150mm round "Osma "gully for our kitchen waste outside ,we have raised the level of the concrete yard and need to lift the gully by about 10cm.
The gully is round with square grill on top and the waste pipe is 150mm circumference it goes to 160mm round waste pipe .
We have been unable to find piece of pipe that will extend the pipe by 10cm.
What can we do ?
