I'm installing a cloakroom suite and have ran into an issue. I had hoped to put the new sink in the same location as the old sink was. I went to attach the waste pipe to the sink and found that I needed an inch or two more waste pipe. No problem, I thought, I'll add an extension. Well, that would have been fine if the existing pipe size was standard, but it doesn't seem to be either a 32mm or 40mm pipe (I've tried connectors for both). It looks as though the pipe is just a little larger than 32mm (35mm possibly?). Anyway, all I need is another inch or so but I can't get anything that seems to connect. Are there universal connections that will attach to varying sizes of pipe that I could use? Or does anyone have any other suggestions. I'm an amateur at this sort of thing so can't get into anything too complicated.
IF THE 35mm SIZE YOU MENTION IN YOUR POST IS THE INSIDE DIAMETER OF THE EXISTING PIPE YOU MAY BE ABLE TO CUT A LENGTH OF STANDARD 32mm COMMPRESSION WASTE PIPE (OD 34.50mm)THAT YOU CAN INSERT/SOLVENT WELD INTO EXISTING TO GIVE THE REQUIRED DIAMETER FOR THE FITTING YOU HAVE AQUIRED.
