It's a 4" internal stack & orangey in colour. It rises just a few inches through the corner of the kitchen floor, before it connects to a plastic solvent-weld coupling & continues upwards in plastic. It's partially boxed in & fairly difficult to access. It looks like plastic, but feels denser when touched. Is there an easy way to tell? There's probably enough room to hold a lighter upto it for a few seconds, to see if it smells like plastic - but surely there's got to be a more sensible way?! Thanks in advance folks!
if its a solvent weld joint it can only be plastic and you should be able to tell anyway with a light tap to here the diffrence plastic underground drainage is orangey in colour
lol ! So is it external plastic then?.. I thought it probably was - seeing as it was glued to the grey plastic coupling above it. I need to connect a 32mm waste pipe into it. A regular strap-on boss will do the job won't it? Cheers again
