I have some new drainage channels fitted for a new patio but they are about 10cm higher than than the drainage hopper so I need to lift the hopper by about 10cm. How can I bridge gap between the hopper and the pipe below? I can't find a replacement hopper, nobody seems to have the right size. I need it to be 230mm square (or in length anyway) and the pipe it connects to at the bottom is 150mm. I have seen one 230mm square but that has a 160mm downpipe from it. so that would be too big unless I get an adapter - even then I might be short of pipe. So is there a simpler way of extending this pipe - maybe with 2 adapters and more 150mm pipe in between?
